Welcome to my blog
Mother Nature Challenge
This post is called; Global warming article
-
Global warning article
-
Let us spread the knowledge about what is known global warming.
-
This article is from the Internet:
Earth
is a very special planet – it is close enough to the sun to receive a lot of energy, but far enough not to be scorched.
It is in what you might call the "goldilocks zone", where the conditions are just right for life as we know it.
To help keep these conditions just right, our planet is wrapped in a layer of greenhouse gases.
This layer keeps the globe warm like a blanket, shielding it from the cold universe – commonly referred to as the greenhouse effect.
While not being the most potent greenhouse gas, carbon dioxide (CO2) is the main driver for the greenhouse effect.
And this is where we have a problem.
The cause of climate change is the unlimited burning of fossil fuels - coal, oil and natural gas - releasing CO2 in the atmosphere at an ever increasing rate.
Because of this the layer of greenhouse gas gets thicker, which in turn makes the Earth warmer.
The reason we do this is to satisfy our hunger for energy. But thanks to human ingenuity there are now smarter ways to make energy.
Culprit coal
-
The biggest climate polluter is the global power sector, and it generates around 40% of all global electricity from coal. We need electricity - but when you take into account the true cost of coal there are much better ways to get it!
According to the International Energy Agency the power sector is responsible for 37% of all man-made Carbon Dioxide (CO2) emissions. It creates about 23 billion tonnes of CO2 emissions per year – in excess of 700 tonnes a second.
In turn, this CO2 continues to heat up our planet and pose an unprecedented threat to us and the environment. Read more here on the impacts of climate change.
Generating electricity through the burning of fossil fuels, in particular carbon-heavy coal, has a greater impact on the atmosphere than any other single human activity.
Coal is the world's most widely available fossil fuel
-
Weaning humanity off coal will not be easy. There is an estimated 2 billion people with no access to domestic electricity, and recoverable reserves of coal exist in about 70 countries, according to the World Coal Institute, an industry lobby group (the largest are in the United States, Russia and China). It is considered a cheap form of energy.
-
But coal is not cheap - if you have to pay for it all
The true cost of coal cannot be found on any balance sheet, but in the lives and health of people and ecosystems. If the global power sector could be made fully accountable for the true costs of pollution and climate change, it would probably turn away from fossil fuel overnight.
Too many governments still subsidize coal production and this distorts the energy market. OECD countries support their coal industry with a whopping $30 billion USD annually.
Much cleaner renewable energies are hampered in their ability to compete with a dirty fuel that is subsidized. Politicians have the power to remove fossil-fuel subsidies or, better still, transfer them to renewable energy.
-
When the true cost is taken into account, renewable energy
begins to look by far the best option for a healthy and sustainable future.

End of article
I have to say that we need to be more active about this global warming before it may become too late? So let the politician start doing something about it.

Yes indeed, who is to blame for today global warming and other threatening weather issues that seem to follow one after the other? Would you think that God has something to do with it, or
do you think that it is mankind entire fault, since we are not looking properly after our planet earth? Right now I can think of a few things and a few people that are playing the game, who is to blame? So, I am going to write down in this post my point of views about this issue, but first let us see some of the natural reasons why this is happening.

Look at what has been happening here in Australia in the last few years and what is happening right now. One cannot help to think that a couple of years ago we were so worried that there
was not enough water in the dams of south east Australia that we started to cut down our water consumption; today it is completely the opposite there are floods everywhere and we don’t know how we can avoid all the damages caused by these floods. Here I need to add that this is not happening only in Australia, but in the entire world there are problems caused by these changes caused from global warming and other factors, so mankind needs seriously look for solutions.
Therefore, we have to hope that in our community at large there are enough clever people that will be able one day to minimize these world wide problems that we are facing today. So I believe that we the people should really try to understand these issues and at the same time try to
let these clever people do their job without causing them hadship, even if sometimes what they have done may not look perfect.
Therefore, in my opinion we should try to understand first fully what is happening, and then we should also give some thoughts about what we are saying or doing, before we try to blame
somebody for what has happened. Anyhow, first of all let us see what is happening today in Australia, and after that we may try to explain who is; playing the game, who is to blame?
--------------------------------------------------
Hereunder are part of reports that I have found on the Internet news, let us start with St George QLD.

Hereunder are part of reports that I have found on the Internet news, let us start with St George QLD.
-
The Balonne River is expected to peak sometime on Tuesday morning with the levees protecting the town of St George likely to hold back the water.
Thousands of people were evacuated from the cotton-growing centre of St George and taken to the safe havens of Dalby and Brisbane, with grave concerns the Balonne River would rise above the town's levee bank.
But those worries eased on Monday afternoon, with the Bureau of Meteorology predicting the river to peak at 14.5 metres on Tuesday - short of the 15-metre mark previously feared.

Now let see NSW, the water moving downstream:

Now let see NSW, the water moving downstream:
-
Residents in north western New South Wales are bracing for more isolation as floodwaters move west across the state.
The State Emergency Service (SES) says more than 10,000 people are likely to be isolated as the flooding from Queensland moves downstream into NSW over the coming days and weeks.

More about NSW floods:
Flooded residents in northwest NSW have received a morale-boosting visit from Governor-General Quentin Bryce.
Ms Bryce flew to Moree on Tuesday morning to witness the clean-up operation after last week's inundations.
"She's been very well received," Moree mayor Katrina Humphries told AAP.
"She's a very well-informed and compassionate lady."

SEQWater senior flood engineers John Tibaldi and Terry Malone, who both testified at the reconvened floods inquiry last week, have stepped aside from their roles at the government authority.
Mr Tibaldi, the lead author of a report branded a fiction at the inquiry, did so on Friday after finishing his testimony.
Mr Malone, who testified on Sunday that no contemporary records on water releases were kept during last year's flood - in breach of dam manual requirements - followed suit on Monday.

At this very moment I am only able to say that this game may turn out to be a very dangerous game so to speak, because the politicians are trying hard to pass the buck without thinking about the future consequences. Of course I am going to explain what I mean hereunder as soon as I have the time.

As a concerned citizen I have reasons to believe that somebody is playing the game, who is to blame? But playing the game in these circumstances is not a good thing to do, because it can only cause more harm than good.
What sort of game is that, you may ask? Look it seems to me that somebody wants to find faults with the engineers that were in charge of Wivenhoe Dam when they had to release the water from the dam to save the dam, because there was far too much water in the dam and there was more water coming in at an alarming rate; what else could they do to save the dam from collapsing under the weight of the water, I believe that, that was the only option left to them release the water as they did. I know that by releasing the water some of Ipswich and Brisbane were
flooded, but so what, if the dam collapsed part of Ipswich and Brisbane could end up in the Pacific Ocean, and therefore the engineers at the Wivenhoe Dam have saved us from a major disaster.
I believe that what is happening now is that the politician want to blame the engineers for the flood in Brisbane, which is something that they did not cause, they want to do that to impress the people just because election time is coming, what else can it be?

Anyhow today the rest of my comments below are going to be brief on this subject, and I am writing them just to give the readers an idea of what articles I am going to add to this post in the future, so:
To start with, as a concerned citizen I would like to ask those who are trying to blame the engineers in charge at Wivenhoe Dam this questions; if they were in charge of the dam at
that time when all this has happened, what would they have done different from what the engineers did? To this question there must be a clear answer and no doubts or two ways about it, because today they have the advantage of knowing already what has already happened then, therefore it should be a clear cut answer and nothing else can be accepted. I hope you see what I mean?
If they don’t know how things had to be done then, even with the advantage of already knowing what was going to happen; then really these people are really worthless to know and listen to
them and perhaps they are to blame themselves, but instead of accepting their mistakes they try to blame somebody else, and so, they are playing the game, who is to blame?

I tell you what I think, the politician and anybody else that can be involved in this need to beware that what they are doing here, because it may cause even harm in the future and I am going to write hereunder what harmful affect can come from these actions, of playing the game, who is to
blame?
-----------------------------------------
Possible harmful effect:
Possible harmful effect from, Playing the game, who is to blame?
So, as I have said these politician or whoever was that has started this who is to blame game going, have to think first of all, that they are wasting taxpayer money, and then, that there may indeed be harmful effects from these political games they are playing; today we have to think that the world needs the best minds available to solve the future problems that we are facing, here we are talking about global warming and all the consequences that that might bring. At this point of time one should ask oneself, who are the best minds that can solve or at least minimise these problems? I suppose most of us will start thinking about the engineers, who else is able to make plans how to control water flow, or whatever other world problems that may arise.
Since this is very likely what is going to happen, those engineers minds that will be involved need to be free from fear of being accused of anything that they have not in reality committed, if they are not free from fear they would not be able to do their best and make new plans for the future.
Therefore politicians first of all should try harder to understand the situation and try first of all to be friendlier with those minds capable to solve the problems, instead of trying to accuse them just to gain some votes from the public. I hope you my readers can see what I mean; we are going to need the work of many engineers in the future, and if it is possible let these engineers work in a friendly environment, so that they will be able to do a better job.
Therefore let the politician see that they are at the very top of the chain of command, and so, they should try to work together with the engineers willing and openly, and since the politician are better at communication skills, they have to try harder to talk to each other in a friendly way, so my point of view here is that the politician are not doing enough for the benefit of the community they represent.

Ocean currents emerge as climate change hot-spots
-
As they warm, they shift
By Richard Chirgwin • Get more from this author
Posted in Environment, 30th January 2012 17:22 GMT
A global study that assesses the temperature change in ocean currents has made two findings – one surprising, the other less so. The unsurprising outcome is that as the Earth’s temperature rises, so does the temps in a collection of major ocean currents; the surprise is that those currents are warming faster than the globe as a whole.
According to the study, published this week in Nature Climate Change, a pattern of warming in the ocean’s long-distance currents has now been identified near Australia, Japan, Africa, and North America.
< a href="http://ad.doubleclick.net/N6978/jump/environment/environment;tile=2;ct=ns;unitnum=2;pos=top;gunit=au_top_mpu;dcove=d;sz=336x280,300x250,300x600,336x600;ord=9Tycr6cCoZHIAADWRjkkAAARW?" target="_blank">
Moreover, the warming is also sending the currents “polewards”, meaning that species migrations already observed in Australia (in which many species are moving southwards at as much as a degree per year) are almost certain to happen on a global scale.
The study, "Enhanced warming over the global subtropical western boundary currents", aims to identify whether, and to what degree, changes in ocean currents may occur due to anthropogenic greenhouse gas forcing.
The currents are important because on their thousands-of-kilometer journeys redistributing heat from equatorial regions to the mid-latitudes, they also release both heat and moisture into the atmosphere.
The currents could be thought of as heat pumps on a global scale, collecting heat nearer to the equator, and dropping it off – along with both moisture and the energy to, among other things, drive storms – further away.
According to the study, the currents are hot-spots in the climate-change picture, warming considerably faster than the average warming of the ocean. Over all the data sets, which comprise the Gulf Stream, Kurshio Current, East Australian Current, Brazil Current, and Aguhlas Current, the average warming over a century has been around 1.2°C, while the global mean rise in temperatures is 0.62°C for the same period.
One of the paper’s authors, CSIRO’s Dr. Wenju Cai, told the ABC’s The World Today that the change is significant because it’s an observation on a global scale. He told the program that while warming of the East Australian Current had already been documented, this study demonstrates that it’s not just happening “in an isolated part of the Tasman Sea.”
Because the change is global, and because the various currents have warmed pretty much in step, the US National Oceanic and Atmospheric Administration’s Michael McPhaden said the synchronized change in ocean circulation is “most likely [caused by] anthropogenic greenhouse gas forcing."
The scale of the change, at two to three times global temperature rises, is one thing that surprised McPhaden, because “we did not think there was such a tight connection between ocean circulation on these small scales near the western boundaries.”
To try and account for natural climate variability, the researchers present a second analysis in which the change in the currents is presented in two periods: from 1900 to 1949, and from 1949 to 2008.
The picture is far less uniform, the study finds, in the first 50 years, with some currents (the Kuriosho, Gulf Stream, and Anguhlas) rising noticeably, while the East Australian and Brazil currents did not. This, they say, might reflect the lower impact of greenhouse-gas forcing in the earlier period, such that some fluctuations were smaller than natural variability. ®
A hat-tip to The World Today, which first carried the story in Australia, and thanks to Dr. Wenju Cai for providing a copy of the paper so that The Register was able to expand upon the original report. ®
Update: Since this story went live, Dr Cai has provided further information via e-mail to The Register regarding the source data used in the study.
Before regular ocean temperature monitoring was put in place, wind speeds – which are fed by energy from the ocean – are the key proxy for ocean temperature. Hence, regarding data towards the 1900 start date of the projection, Dr Cai wrote, “Much of the early changes are inferred from winds, for which we have more observations.”
While “reconstructed data certainly have limitations,” he wrote, winds “are a major driver of climate change.”
Importantly, he noted that the outputs of this study agree with predictions from other sources: “Climate models project a synchronized warming under various emission scenarios”.
This suggests a secondary, but still important, result of this study: it serves to help validate other climate models.
Data comes from a variety of sources, Dr Cai said: “Since 1950, we have started to [get] good data, though the coverage is sparse, and the amount increases dramatically since 1979 (the satellite era).
“Since 2003, we have built a network of 3,000 floats around the globe, which measure SST [sea surface temperature] every 10 days.
“However, for over 60 years, CSIRO has continuous monthly measurements of ocean temperature of Maria Island in Tasmania, which show a warming rate of up to 3°C.” ®

End of report:
I hope you see what I mean, for instance; it is very worrying to know this last bit about Maria Island in Tasmania.

The picture is far less uniform, the study finds, in the first 50 years, with some currents (the Kuriosho, Gulf Stream, and Anguhlas) rising noticeably, while the East Australian and Brazil currents did not. This, they say, might reflect the lower impact of greenhouse-gas forcing in the earlier period, such that some fluctuations were smaller than natural variability. ®
A hat-tip to The World Today, which first carried the story in Australia, and thanks to Dr. Wenju Cai for providing a copy of the paper so that The Register was able to expand upon the original report. ®
Update: Since this story went live, Dr Cai has provided further information via e-mail to The Register regarding the source data used in the study.
Before regular ocean temperature monitoring was put in place, wind speeds – which are fed by energy from the ocean – are the key proxy for ocean temperature. Hence, regarding data towards the 1900 start date of the projection, Dr Cai wrote, “Much of the early changes are inferred from winds, for which we have more observations.”
While “reconstructed data certainly have limitations,” he wrote, winds “are a major driver of climate change.”
Importantly, he noted that the outputs of this study agree with predictions from other sources: “Climate models project a synchronized warming under various emission scenarios”.
This suggests a secondary, but still important, result of this study: it serves to help validate other climate models.
Data comes from a variety of sources, Dr Cai said: “Since 1950, we have started to [get] good data, though the coverage is sparse, and the amount increases dramatically since 1979 (the satellite era).
“Since 2003, we have built a network of 3,000 floats around the globe, which measure SST [sea surface temperature] every 10 days.
“However, for over 60 years, CSIRO has continuous monthly measurements of ocean temperature of Maria Island in Tasmania, which show a warming rate of up to 3°C.” ®

End of report:
I hope you see what I mean, for instance; it is very worrying to know this last bit about Maria Island in Tasmania.

TAKING NOTICE OF GLOBAL WARMING
-
Nobody seems to take notice of global warming, so today again we are
writing a post in my blog called, Mother Nature Challenge and we are talking
about global warming; it is something that cannot be avoided, because as soon
as I/we am/are in the open meaning outside or in the country, we notice that
something is different from the way it used to be when we were young. We seem
all to notice that the weather is not what it used to be, it changes suddenly
from hot to cold or vice verse, there are extreme spell of dry weather for a
long time, then it starts to rain and soon that welcome rain becomes too much
because it rains for days and it may even flood us, like it did last year here
in Brisbane, now because of all these changes in the weather pattern, one has
reasons to believe that we might have made unwelcome changes to the weather; so
we really need to think what mankind needs to do. We have been advised from
many learned people and if we just look in the Internet the reasons are
explained very well from the expert, Just look at a small part of this article
that I have just copied hereunder to see what I mean, and I quote:
-
The effects of global
warming are the ecological and social changes caused by the rise in
global temperatures. Evidence of climate
change includes the instrumental temperature record, rising sea levels, and decreased snow cover in the Northern Hemisphere.[6] Most of the observed increase in global
average temperatures since the mid-20th century is very likely due to the
observed increase in human greenhouse gas concentrations[7]. Projections of future climate change
suggest further global warming, sea level rise, and an increase in the
frequency of some extreme weather events.[8] Parties to the United Nations
Framework Convention on Climate Change (UNFCCC) have agreed to implement
policies designed to reduce their emissions of greenhouse gases to avoid dangerous climate change.
End of quote.
-
So, here I may say again that we have really
done something that is against Mother Nature liking, therefore, now it is time
that we challenge ourselves and try to meet the challenge that Mother Nature
seems to throw at us? That is do not make more mistakes, because if you do you
will be paying dearly even with our lives, because it may come a time when it
will be very hard to live well on this planet earth.

When will the giant economies wake up and do their duty for all humanity?
We the people of the world seem to worry a lot about climatic warming and the changes that will follow, but the people that count are still thinking first about how to make more money with the mighty dollars, it is time they wake up, we are saying this because of some news we have just read. Hereunder is part of what was reported:
-
(A broad coalition of civic leaders, elected officials, and labor, environmental and social activists launched a campaign Wednesday aimed at convincing U.S. politicians that they should curb greenhouse gas emissions for moral and ethical reasons.
The Climate Ethics Campaign — which kicked off with a Capitol Hill news conference headlining Senate Environment and Public Works Committee Chairman Barbara Boxer (D-Calif.) — comes as negotiators are struggling to make progress at U.N. climate talks in Durban, South Africa.

“We believe it’s time to talk about our moral obligation to prevent the human suffering -created by climate change, to safeguard the poor and most vulnerable communities from harm they did not create, and to protect the natural environment that is the source of all life,” said campaign coordinator Bob Doppelt, executive director of the Resource Innovation Group, a nonprofit association affiliated with Willam¬ette University.
But the call also comes at a moment when Congress has shown little appetite for tackling the issue of global warming. There is no serious drive to pass a cap on greenhouse gas emissions or a more-modest federal renewable energy standard.
The climate talks are the first in years with not a single member of Congress attending. Only a handful of congressional aides are making the trip.)

I hope you see what I mean when I say that people priorities are not in favour to help the world climate, as they think first and foremost about the mighty dollars to make?
We really need to wake up before it becomes too late, don’t you agree?

Top Ten Environmental Concerns of the 21st Century
-
I have found this information on the Internet in Hub Pages, so if you would like to read it in full you need to go to hub pages and find author (kerryg) You see, what I am writing in this post is only a small part of his hub just to give you an idea of what he is talking about.
-
What are the top ten environmental problems facing the world today?
-
A recent scientific paper published in Nature attempted to answer this question, with a twist. The Earth has spent roughly the last 12,000 years in a period of unusual climate stability known as the Holocene era. To put this era in perspective, all major human civilizations have existed since the beginning of the Holocene. In fact, humans have only practiced agriculture for roughly the last 10,000 years. This all-important development, which allowed civilizations from the ancient Sumerians to our own to thrive, was made possible by the stable climate of the Holocene
Unfortunately, this stable, pleasant period is currently coming to an end, and there is strong reason to believe that this is not the result of a change in the natural cycles of the Earth, but rather that the change is caused by human activity.
The authors of Planetary Boundaries: Exploring the Safe Operating Space for Humanity, attempted to identify the most serious environmental threats the human race currently faces, and identify the potential "tipping points" beyond which the pleasant Holocene era would disappear and the Earth's natural resources would be seriously depleted.
The ten most serious environmental problems they identified were:
Learn More
• Ozone Science
10. The Stratospheric Ozone Layer
The ozone layer filters out the most harmful wavelengths of UVB ultraviolet radiation from the sun before it reaches the earth's surface. A depleted ozone layer would mean increased rates of skin cancer for humans, as well as damage to plants and ecosystems. Ozone depletion received a lot of attention in the 1970's and 80's when scientists discovered a giant and growing "hole" in the ozone layer above Antarctica.
Fortunately, the scientists were able to convince the world community to act quickly to limit the production of ozone depleting substances such as CFCs and halons and the problem of ozone depletion today seems to be on the path to successful resolution, though due to the long lifetime of ozone depleting compounds the Antarctic ozone "hole" is not expected to recover completely until 2050 and the overall levels of ozone in the atmosphere will recover to pre-1980 levels only about 2060-2075.
The goal for the future will be to maintain the progress we have already made on this issue.
9. Land Use Changes
The authors of Planetary Boundaries chose Land Use Changes as one of their top environmental concerns, which I felt was a slightly redundant choice, because changes in land use, for the most part, have the same negative effects as several of their other choices. For example, loss of wildlife habitat leads to loss of biodiversity. Depending on what the habitat is replaced with, the change can also lead to air or water pollution from factories and farm fields, depleted groundwater reserves due to impervious surfaces such as city roads, and carbon emissions from almost any human activity you could name.
Land Use Changes are also particularly difficult to define a "tipping point" for because their effects vary so significantly, so that in fact the exact environmental impact of one land use change is different from the impact of every other land use change ever made.
I feel a less redundant and easier to measure choice might have been soil depletion due to erosion, desertification, and unsound agricultural practices, among other factors.
There is a lot more to learn if you can find the hub.

Here we are looking again what to do to help planet earth?
This report I found on the Internet.
-
www.sayyesaustralia.org.au/
I have found this article on the Internet, it seems to me that it is interesting enough to take into consideration, if we want make a difference and help planet earth, so I have written it hereunder, because it gives very good explanation.
-
Our atmosphere is but a thin layer of gas around a huge bulky planet. This gaseous outer ring and its greenhouse effect make life on Earth possible–and could destroy life as we know it.
The sun is the Earth’s primary energy source, a burning star so hot that we can feel its heat from over 150 million kilometers away.
About one third of this solar energy is reflected back into the universe by shimmering glaciers, water and other bright surfaces. Two thirds, however, is absorbed by the Earth, thus warming land, oceans, and the atmosphere.
Much of this heat radiates back out into space, but some of it is stored in the atmosphere. This process is called the greenhouse effect. Without it, the Earth’s average temperature would be a chilly -18 degrees Celsius, despite the sun’s constant energy supply.
In a world like this, life on Earth would probably have never emerged from the sea. Thanks to the greenhouse effect, however, we enjoy a comfortable average temperature of 14 degrees Celsius.
So, how does it work?
Radiator in space
Only about half of all solar energy that reaches the Earth is infrared radiation, which causes warming. The other half only translates into heat once it hits Earth and is reflected back into space as infrared radiation.
This transformation of solar radiation into infrared radiation is crucial, because infrared radiation can be absorbed by the atmosphere. Like a radiator in the middle of a room, our atmosphere radiates this heat in all directions.
How is this radiation absorbed?
Sunrays enter a greenhouse, heat up the ground, which, in turn, heats up the air inside the greenhouse. The glass roof and walls trap that warm air and temperatures increase.
Earth has no glass walls, but it does have the atmosphere, and within the atmosphere it has greenhouse gases.
Ninety-eight percent of the Earth’s atmosphere is made up of nitrogen, oxygen, and argon. But they do not absorb much infrared radiation, and don't contribute to the greenhouse effect.
Greenhouse gases like water vapour, carbon dioxide, ozone, methane, nitrous oxide, and chlorofluorocarbons do absorb heat, and thus increase atmospheric temperatures.
