Judith Curry Arctic ice melt paper
- Roger Pielke writes:
"Humans do affect the climate system, and it is indeed important to
take action on energy policy-but to connect energy policy and
disasters makes little scientific or policy sense. There are no signs
that human caused climate change has increased the toll of recent
disasters, as even the most recent extreme event report of the
Intergovernmental Panel on Climate Change finds."
This is wrong. I just posted the peer reviewed report:

Everywhere in the IPCC report Pielke refers to the IPCC associates
climate change and extreme weather events and disasters. Though
Pielke could be privy to something new, he apparently refers to the
IPCC report predicated by this press release dated March 28, 2012.
IPCC releases full report on Managing the Risks of Extreme Events and
Disasters to Advance Climate Change Adaptation (SREX)
Geneva, 28 March 2012 - Evidence suggests that climate change has led
to changes in climate extremes such as heat waves, record high
temperatures and, in many regions, heavy precipitation in the past
half century, the Intergovernmental Panel on Climate Change said
Climate extremes, or even a series of non-extreme events, in
combination with social vulnerabilities and exposure to risks can
produce climate-related disasters, the IPCC said in its Special
Report on Managing the Risks of Extreme Events and Disasters to
Advance Climate Change Adaptation (SREX).
While some extreme weather and climate events lead to disasters,
others do not. Policies to avoid, prepare for, respond to and recover
from the risks of disaster can reduce the impact of these events and
increase the resilience of people exposed to extreme events, the IPCC
shows in the report, published on Wednesday
At the same time, as the IPCC notes in the report, limits to
resilience are faced when thresholds or tipping points associated
with social and/or natural systems are exceeded, posing severe
challenges for adaptation.
"The main message from the report is that we know enough to make good
decisions about managing the risks of climate-related disasters.
Sometimes we take advantage of this knowledge, but many times we do
not," said Chris Field, Co-Chair of IPCC's Working Group II, which
together with Working Group I produced the report. "The challenge for
the future has one dimension focused on improving the knowledge base
and one on empowering good decisions, even for those situations where
there is lots of uncertainty," he said.
The IPCC released the Summary for Policymakers (SPM) of the report in
November 2011. The full report released today provides the basis for
the key conclusions first presented in the SPM. It offers a greater
understanding of the human and economic costs of disasters and the
physical and social patterns that cause them. It enables
policy-makers to delve into the detailed information behind the
findings to examine the material on which the IPCC based its
Advance Climate Change Adaptation (SREX) is the latest), Technical
Papers, Methodologies and other key documents. Together these have
become the standard references for policymakers and scientists.
