Report of concerned
citizen
I am a
concerned citizen and I am thinking that all is not well, because we don’t take
global warming seriously when we should; so, I am writing this post to
highlight my concerns. Now apart what I can say for myself, I have collected
some information from the web, where the expert tell us a few things about this
issue, and this information will be pasted here-under.
I believe that
we should all be concerned about global warming, because it seems to me that it
is being partly forgotten, even these days that there are these huge
hurricanes, like Hurricane Sandy which has devastated many states in America,
the majority of people don’t really try to talk what can be done to stop global
warming, they don’t seem interested enough to do anything much, and if they do
it is like a passive interest. What else should happen before we all try harder
to understand the situation and do something about it?
For my own
part I can describe what I see is happening in these parts of Australia. A few
years ago we had a drought then we have had two years with a lot or rain and
floods, and now the drought seems to be starting again; the weather here seems
to change suddenly from very wet to dry or very dry.
Now, let me
talk about my life experience about the weather, I have been living in Brisbane
for more than fifty years, and because I have been in a farm when I was young I
always look at what is the weather like every day, so I have a pretty good idea
what is going on and I am worried; I am worried because this issue of global
warming, or perhaps we should call this climatic change are not taken seriously
enough. I can see and feel the changes that are taking place weather-wise and I
hope that there is something that we can do, so I am looking for sign that
steps are being taken from governments. But they don’t seem to care that much,
they only seem to mention it every now and then and everything they do is very
little compared to what needs to be done.
So, I have
decided to write a few hubs or posts to publish on the internet, So that, I can
be counted in, as one that is in favor of doing something about this problem
of global warming.
Here I need
to say, that personally I cannot add much to what has already been written from
the experts, so, I am going to copy some reports that I find worth reading in
the hope that you my readers read them and let your own government know what
you think. Here I have also to say that everyone of us can help a little bit,
starting from the way we live our lives, for instance even recycling is one of
those things that can help, of course there are also many other things to
consider.

So let us
see what the experts say:

The results are in and the
reality of global warming is beyond dispute or debate. It’s not just an
environmental issue. It affects our public health and national security. It’s
an urgent matter of survival for everyone on the planet — the most urgent
threat facing humanity today. It’s going to take action from you and all of us
working together.
The second step, Keep reading below, and share this with
friends.
Global warming isn’t opinion.
It’s a scientific reality. And the science tells us that human activity has
made enormous impacts to our planet that affect our well-being and even our
survival as a species.
The world’s leading science
journals report that glaciers are melting ten times faster than previously
thought, that atmospheric greenhouse gases have reached levels not seen for
millions of years, and that species are vanishing as a result of climate
change. They also report of extreme weather events, long-term droughts, and
rising sea levels.
Fortunately, the science also
tells us how we can begin to make significant repairs to try and reverse those
impacts, but only through immediate action. That’s why we urge you to join us.

spreading the word and sharing this with others, our collective power will
force governments, corporations, and politicians everywhere to pay attention.

What is Global Warming?
The Earth as an ecosystem is
changing, attributable in great part to the effects of globalization and man.
More carbon dioxide is now in the atmosphere than has been in the past 650,000
years. This carbon stays in the atmosphere, acts like a warm blanket, and holds
in the heat — hence the name ‘global warming.’
The reason we exist on this
planet is because the earth naturally traps just enough heat in the atmosphere
to keep the temperature within a very narrow range – this creates the
conditions that give us breathable air, clean water, and the weather we depend
on to survive. Human beings have begun to tip that balance. We’ve overloaded
the atmosphere with heat-trapping gasses from our cars and factories and power
plants. If we don’t start fixing the problem now, we’re in for devastating
changes to our environment. We will experience extreme temperatures, rises in
sea levels, and storms of unimaginable destructive fury. Recently, alarming
events that are consistent with scientific predictions about the effects of
climate change have become more and more commonplace.
Environmental Destruction
The massive ice sheets in the
Arctic are melting at alarming rates. This is causing the oceans to rise.
That’s how big these ice sheets are! Most of the world’s population lives on or
near the coasts. Rising ocean levels, an estimated six feet over the next 100
years or sooner, will cause massive devastation and economic catastrophe to
population centres worldwide.
The United States, with only
four percent of the world’s population, is responsible for 22% of the world’s
greenhouse gas emissions. A rapid transition to energy efficiency and renewable
energy sources will combat global warming, protect human health, create new
jobs, protect habitat and wildlife, and ensure a secure, affordable energy
future.
Health Risks
Malaria. Dengue Fever.
Encephalitis. These names are not usually heard in emergency rooms and doctors’
offices in the United States. But if we don’t act to curb global warming, they
will be. As temperatures rise, disease-carrying mosquitoes and rodents spread,
infecting people in their wake. Doctors at the Harvard Medical School have
linked recent U.S. outbreaks of dengue fever, malaria, hantavirus and other
diseases directly to climate change.
Catastrophic Weather
Super powerful hurricanes,
fueled by warmer ocean temperatures are the “smoking gun” of global warming.
Since 1970, the number of category 4 and 5 events has jumped sharply. Human
activities are adding an alarming amount of pollution to the earth’s atmosphere
causing catastrophic shifts in weather patterns. These shifts are causing severe
heat, floods and worse.
Five Things We Can All Do
·
Spread the word, share the learning. Send this link to family,
friends, and colleagues. Share why this is so important.
·
Put the heat on your elected officials to support legislation to
stop global warming.
·
The power of the pocketbook; buy green products and donate to
environmental organizations.

I hope you see what I mean and start thinking what you can do to
help?
-----------------------------------
Some
politicians know that we need to do something about global warming soon, see
what President Barack Obama has said: I hope that he would be able to do
something about it.
We now know without
a doubt that global warming is threatening us with higher temperatures, more
drought, more wildfire, more flooding, and more erosion of our coastal
communities. People who don’t believe this can yell about it as loudly as they
want, but it doesn’t change the fact that the overwhelming scientific evidence
has proven this over and over again. We must act now with the rest of the world
to curb emissions so that we can leave our children a safer, healthier planet.
-----------------------------------------
Anyhow,
during these last few days, we have all heard about Hurricane Sandy and the
destruction it has caused in America and nearby.
This is one of the
reports I found on the web.
Hurricane Sandy: Costs to Come
By Ryan Avent (The Economist) -
November 1, 2012
THE economic approach to global
warming is relatively straightforward. The emission of greenhouse gases
generates a negative spillover—global warming—that harms others. Someone
driving a car emits carbon dioxide into the atmosphere which contributes to
climate change, but because most of the cost of the car’s contribution to
warming will be felt by people other than the driver, he has an incentive to
drive too much. Aggregate that decision to emit too much across all of the
world’s population, and you get a serious economic problem.
Luckily, there is a solution.
By taxing the emission of greenhouse gases, one can align private and public
costs. The cost of the driver’s emissions will be “internalised”, he’ll drive
less, emissions will fall, and warming will slow. All that remains is to tot up
an estimate of the “social cost of carbon” and convert that into an optimal tax
rate. And in fact, many models reckon the tax need not be too high, as it makes
sense to accommodate quite a lot of warming. The costs of climate change will
mount over time, but so too will global income, the thinking goes. Economic
actors are resilient and will be able to adapt. All in all, we shouldn’t expect
global warming to dent expected GDP growth so much that a stifling tax rate is
necessary.
There is some wisdom in this analysis.
Remarkably, Americans have adopted what is effectively an even more sanguine
view of the harm from warming, by refusing to tax carbon and investing quite
conservatively in green technology and research. But as the devastation from
Hurricane Sandy makes clear, the economic approach is a bit too anti-septic and
simplistic a way of understanding and responding too an incredibly complex and
potentially catastrophic climate phenomenon. The American approach is
out-and-out reckless.
With the superstorm now
dissipating, estimates of its economic impact are beginning to emerge. Kate
Mackenzie comments on some of them here. Goldman Sachs economist Jan Hatzius
notes that damage estimates of $10 billion to $20 billion look small and may
well be revised up (Hurricane Katrina was responsible for roughly $113 billion
in damage). Yet the observed impact of the storm on economic numbers could be
even smaller. October data will probably take a hit, but much of the shortfall
may be made up in November and December such that fourth-quarter GDP will
hardly register the event. Pimco’s Mohamed El-Erian reckons that the storm will
show up in the fourth-quarter data, but mostly because state and federal
governments are less fiscally willing and able to provide support. Still, the
fact that such an epic storm might not even knock the GDP statistics off track
lends credence to those who argue, for instance, that things like a massively
expensive sea wall to protect New York City or an Apollo programme for green
energy would represent useless waste.
But there are two problems with
this mode of thinking. One is that the economic resiliency that allows us to
shift economic activity across time and geography, holding down the cost of
such storms, has its limits. People cluster together in New York City, despite
the high cost of living, because of the extraordinary advantages of being
there, surrounded by other skilled professionals. There are “returns to scale”
that hold New York together—productivity per person rises with population and
density. Given limited disruption, the city will quickly bounce back, but a
larger disaster could disperse enough of the city’s people and businesses to
undermine the scale that acts as New York’s gravity. That could generate very
large economic losses. New York can’t easily be replaced, and even if it were
logistically possible to create another megacity there’s no guarantee that
resources would re-congeal there. They might stick, instead, to lots of smaller
cities: a much less productive distribution.
The more serious issue,
however, is simply that GDP is not capturing everything we care about. GDP is a
flow of income, for one thing. A storm that destroys existing wealth could
actually raise the flow of production in the short term as people rebuild, such
that higher GDP growth might nonetheless mean less wealth overall. Moreover,
GDP is a very imperfect measure of human welfare. Even if GDP and wealth were
relatively unharmed by the storm, we might nonetheless want to prevent a great
deal of human suffering. The damage to America’s northeast pales in comparison
with the destruction wrought in Haiti, but because Haitians are so poor the
economic cost of the damage there is almost imperceptible. The fact that the
average Haitian emits about a hundredth as much carbon dioxide each year as the
typical American suggests that unaccounted-for economic injustice may be at
least as big a concern with global warming as underestimated human costs.
And so it would be entirely
appropriate if the damage done by Sandy shakes Americans out of complacency on
the issue of global warming, despite the relatively tolerable price tag of the
storm. The storm is costlier than the estimated bill reflects. And future
storms will be costlier still.
Many scientists and journalists
are cautious in listing climate change as a causal factor behind a storm like
Sandy. Understandably so: weather emerges as part of a complex system, and it
would be impossible to say whether a storm would or would not have materialised
without global warming. But scientists are becoming ever less shy in drawing a
line between a higher frequency of “extreme” weather events and a warming
climate. Climate shifts the probability distribution of such events, and so
global warming may not have “caused” Sandy, but it makes Sandy-like storms more
probable. As the ever-less-funny joke goes, 500-year weather events seem to pop
up every one or two years these days. Frequency and intensity of storms aside,
future hurricanes that hit the east coast will do so atop rising sea levels.
Contemplate the images of seawater rushing over Manhattan streets and into
subway and highway tunnels. Then consider that sea levels are rising. And then
reflect on the fact that New York is very much like a typical megacity in being
located on the water; tracing a finger around America’s coastlines leads one
past most of the country’s largest and richest cities.
Americans may absorb all of
this and decide that the smart choice continues to be a course of inaction.
They may continue to believe that the storms—and droughts and heat waves and
blizzards and floods—to come will be manageable because they’ll be richer and
well-equipped to adapt. Hopefully, there will at least be a better sense of
what that is likely to mean and the trade-offs it will involve. Adaptation will
be an ongoing, costly slog, with a side order of substantial human suffering.
It will be one American icon after another threatened. Adaptation is not going
to be easy. Hopefully Americans will ask themselves whether it’s so much worse
than the alternatives—high carbon taxes or large public investments or
both—after all.

As I have said I am posting this, in the hope that some people
read this and become aware of things that need to be done.
May God bless us and help us all?
