Over the last two weeks significant news has occurred on the Climate Change front. First was the report from the U.S. Department of Defense (DoD) on the security threat posed by Climate Change, second was the Fifth Assessment Report (AR5) of the Intergovernmental Panel on Climate Change (IPCC), and last was the takeover of the U.S. Senate by the Republican party (GOP).
The DoD report analyses
the U.S. military’s place in combating and adapting to climate change. The U.S.
has over 7000 bases around the globe all of which need to deal with Climate
Change. Defense Secretary Hagel, who as senator once signed a resolution
labeling Climate Change as more or less baloney, has come around. “… we will integrate
Climate Change considerations into our planning, operations and training,” he
told an audience recently.
The IPCC report follows on its last one in
2007 (AR4). (For a brief note on what, who the IPCC is go here IPCC .)
What has changed since the AR4 is that the
situation has worsened and the time to address Climate Change has shortened.
I have selected and edited some excerpts from the Synthesis Report released November 2, 2014:
I have selected and edited some excerpts from the Synthesis Report released November 2, 2014:
1. Human influence on the climate system is
clear, and recent anthropogenic emissions of greenhouse gases are the highest
in history. Recent climate changes have had widespread impacts on human and
natural systems.
1.2 Anthropogenic greenhouse gas emissions
have increased since the pre-industrial era, …, and are now higher than ever.
This has led to atmospheric concentrations of carbon dioxide, methane and
nitrous oxide that are unprecedented in at least the last 800,000 years. Their
effects, … are extremely likely to have been the dominant cause of the observed
warming since the mid-20th century...
2. Continued emission of greenhouse gases
will cause further warming and long-lasting changes in all components of the
climate system, increasing the likelihood of severe, pervasive and irreversible
impacts for people and ecosystems. Limiting climate change would require
substantial and sustained reductions in greenhouse gas emissions which,
together with adaptation, can limit climate change risks...
2.2 Surface temperature is projected to
rise over the 21st century under all assessed emission scenarios. It is very
likely that heat waves will occur more often and last longer, and that extreme
precipitation events will become more intense and frequent in many regions. The
ocean will continue to warm and acidify, and global mean sea level to rise.
2.3 Climate change will amplify existing
risks and create new risks for natural and human systems. Risks are unevenly
distributed and are generally greater for disadvantaged people and communities
in countries at all levels of development.
2.4 Many aspects of climate change and
associated impacts will continue for centuries, even if anthropogenic emissions
of greenhouse gases are stopped. The risks of abrupt or irreversible changes
increase as the magnitude of the warming increases.
3. Adaptation and mitigation are
complementary strategies for reducing and managing the risks of climate change.
Substantial emissions reductions over the next few decades can reduce climate
risks in the 21st century and beyond, …
3.2 Without additional mitigation efforts
beyond those in place today, and even with adaptation, warming by the end of
the 21st century will lead to high to very high risk of severe, widespread, and
irreversible impacts globally (high confidence)...
3.4 There are multiple mitigation pathways
that are likely to limit warming to below 2°C relative to pre- industrial
levels. These pathways would require substantial emissions reductions over the
next few decades and near zero emissions of CO2 and other long-lived GHGs [greenhouse
gases] by the end of the century...
4. Many adaptation and mitigation options
can help address climate change, but no single option is sufficient by itself.
Effective implementation depends on policies and cooperation at all scales, and
can be enhanced through integrated responses that link adaptation and
mitigation with other societal objectives...
This report, the result of hundreds of the
world’s leading climate scientists synthesizing tens of thousands of research papers
published over the last seven years, barely made a ripple in the media. Why?
Because it was buried by the U.S. national elections and the non-stop frenzy of
the media in covering it. (The N.Y. Times did manage a short news item on the
report.)
What the election results mean for the future
of addressing Climate Change is that any serious action is in serious trouble. Republicans
have made known they intend to fast track the tar sands Keystone XL pipeline
and squash the oversight of the EPA on greenhouse gases and power plant emissions.
I’m guessing that’s for a start. The agenda will be more fossil fuels not less.
A direct result of the takeover of the Senate
by the GOP is the change in the committee chair of the Environment and Public
Works Committee that now goes to Senator James Inhofe, notorious for his statement,
often repeated, that Climate Change is a hoax – he even wrote a book about it.
We can expect useless Senate hearings and harassment of scientists by subpoenas
to appear before his committee.
The GOP now is in charge of Congress and signs
so far point to no action and even backwards steps on addressing climate change
(See LA Times 11/8/14 ). In a subtle change of stance the party line has shifted from denying Climate
Change is a real threat that needs to be confronted to the refrain “… I don’t know
[if climate change is happening, ..or real, ..or we are causing it], I am not a
scientist.” Sure they’re not scientists but why don’t they listen to scientists?
They must realize they appear to be utter fools. Where is the courage? What happened
to this party?
