The Truth About Climate Change (David Attenborough, BBC)
From Newsweek by Max Strasser
The
planet is poised for disaster, according to a landmark study released
yesterday.
Forests will burn, cities will flood and infrastructure will
collapse under the strain of a warming climate.
Climate change will also
lead to increased food insecurity and even wars over resources, says the report by the Intergovernmental Panel on Climate Change (IPCC), which was set up by the United Nations' Environment Program.
The
report, written by more than 300 scientists and based on thousands of
peer-reviewed research documents, says some of the problems of climate
change can be mitigated if warming doesn’t continue on its current
trajectory.

Greenland’s immense ice sheet is melting as a result of climate change.
But
as scientists issue yet another dire warning about the perils of
man-made climate change, will governments take action?
People concerned
about the future of humanity hope so. But science and politics are
separate topics.
The
two biggest greenhouse gas emitters, China and the United States,
remain particularly stubborn on serious cuts to greenhouse gas emissions
that could mitigate climate change.
And the U.N. framework for a
comprehensive approach to the problem remains mired in seemingly endless
negotiations, despite increasingly urgent calls to action from the
scientific community.
“The
IPCC performs an extremely important function but I would be surprised
if their truth-telling was the magic formula to get countries moving,”
says Ruth Greenspan Bell, a public policy scholar who works on climate
change issues at the Woodrow Wilson International Center for Scholars.
The
report comes as preparations are underway for more international
negotiations.
There have been more than 17 high-level international
conference in the last 9 years. In September, heads of state, business,
industry and advocacy groups will meet in New York at the invitation of
U.N. Secretary General Ban Ki-moon to discuss climate change.
If the sea level continues to rise at its current rate, Kiribati will probably be completely submerged by the end of the century.
Next
year, Paris will host the 21st United Nations Climate Change
Conference, where governments from 195 countries will once again meet to
establish emissions reduction targets.
“This
[report] was timed to come out before the build-up to the 2015 Paris
conference,” says Robert Falkner, a professor of international relations
at the London School of Economics who studies environmental
negotiations.
“Negotiators are expecting a big boost.”
They could use a boost.
In
the past, climate change negotiations under the U.N. framework have
been less than productive. In 2009, the Copenhagen Climate Change
Conference was supposed to establish a binding agreement for deep
emissions cuts that would keep global temperature increases below 1.5°C.
Instead, the parties came up with a non-binding “accord” that calls on
countries to “take note” of reduction targets.

The
weak agreement at Copenhagen—a disappointment to both poor countries
who will bear the brunt of climate change’s effects and to some of the
European countries that attempt to be leaders on the issue—was
engineered by representatives from the United States and China, the
world’s two largest emitters of greenhouse gases and the two biggest
obstacles to climate change agreements.
There
may be some encouraging signs in the U.S. though. Secretary of State
John Kerry said the IPCC report should be a wake-up call.
“Unless
we act dramatically and quickly, science tells us our climate and our
way of life are literally in jeopardy," Kerry said.
“There are those who
say we can't afford to act. But waiting is truly unaffordable. The
costs of inaction are catastrophic.”
The
Obama administration may hope to use the IPCC’s sobering warnings to
galvanize support for carbon emissions-reduction plans in the United
States, one of the few countries in the world where climate change
deniers hold positions in government (in Congress and at the state
level).
The White House has increasingly turned to executive orders on
climate change-related issues to circumvent an obstinate Congress.
Some areas of the globe are especially vulnerable to rising sea levels.
As land recedes under advancing waters, governments are faced with the costs of building defensive seawalls and relocating coastal populations — and in some extreme cases, finding new homes for entire island nations.
But there is obstinacy across the world, too.
China,
the world’s largest emitter of greenhouse gases, is hesitant to agree
to emissions targets that could curtail its rapid economic development
and industrialization.
“I
don’t see any new flexibility in the Chinese negotiating position,”
said Elizabeth Economy, an expert on Chinese environmental policy at the
Council on Foreign Relations, of the upcoming climate change
negotiations.
“They’ll say that their actions are appropriate to their
level of development.”
China
has reduced coal consumption as a percentage of its energy sources but
the real amount of coal used has grown, as has the amount of greenhouse
gas emissions per capita.
Even
as the comprehensive U.N.-backed talks over emissions reductions stall,
there may be room for progress on mitigation efforts, some advocates
say.
And the IPCC report may help spur that.
The
report predicts that climate change could cut global economic output by
up to 2 percent a year if temperatures rise by 2°C, which many
scientists predict the earth is on track to exceed.
More
solid evidence and serious warnings like these shift businesses’
cost-benefit calculations, says Falkner, pointing to institutional
investors and the insurance industry as particularly concerned about
climate change.
With
international negotiations stuck in limbo, piecemeal changes may be the
only path forward for avoiding the disastrous consequences of continued
global warming predicted by the IPCC’s report.
“There
is no silver bullet for resolving this challenge,” says Bell.
“A better
approach might be silver buckshot, a lot of initiatives with the idea
that some will make progress and others won’t.”
As
a team of hundreds of scientists predicts an impending dystopia, it’s
likely that many concerned people will to try whatever kind of
initiatives might make progress.
