Appeals to Curry's credentials doesn't hide the fact that she is just another attention seeking climate gadfly. She just loves to stir the pot with her opinions.

And precisely how would that be any different that say Phil Jones, Mike Mann, Gavin Schmidt, Kevin Trenberth, Peter Gleick...etc,.etc?

insert quote....glass houses....stones.

It's not, unless you cite the actual studies. She's another one who loves throw up strawmen and to proclaim since we don't know everything, we therefore can't know anything.

[ Are you claiming there have never been snowless winters in North America before?....I can remember at least two not that many years ago.

What I'd like to claim is the recent USDA Plant Hardiness Zone update which shows N.A. growing zones getting warmer.

take it up with these guys

Agriculture officials stressed that the new map is not a tool to measure climate change and that many of the boundary shifts are the product of better and more complete data and sophisticated computer algorithms.

Right, you mean all those flaky surface station sites and problematic climate computer algorithms the scientists devised must have been better then you thought. Of course it's not a tool to measure climate change, it's just an indicator of same.

as I said.....take it up with the people who publish the map.

I don't trust these so-called scientists who beg for government funding.

Why is that? How does that affect the science? Two plus two is still four, no matter how much money, or lack of it, is used.

Special Report
Managing the Risks of Extreme Events and
Disasters to Advance Climate Change
Adaptation (SREX)

From the last paragraph of the Summary for Policymakers:

There are many approaches and pathways to a sustainable and resilient future. [8.2.3, 8.4.1, 8.6.1, 8.7] However, limits to resilience are faced when thresholds or tipping points associated with social and/or natural systems are exceeded, posing severe challenges for adaptation.

Timely!

(My emphases. Even in these kinds of official documents, the issue of the danger of crossing tipping points is coming up more and more.)

Here's the discussion of it at ClimateProgress:

http://thinkprogress.org/romm/2012/03/28/454281/global-warming-sharply-increases-likelihood-of-outlandish-heat-waves/

In the case of extreme weather, my guess is that decades from now, people will look back on the staggering growth in off-the-charts “outlandish” extreme events in the past few years and conclude that a regime change had occurred in the climate.

That's pretty much my take.

U.N. report: Global warming will trigger stronger hurricanes, longer heat waves

Heat waves are likely to intensify and last longer from California to the U.S. East Coast as global warming takes hold, according to the United Nations’s most comprehensive report on extreme weather events.

Average wind speeds of hurricanes are likely to increase, with projected sea level rises compounding the impact of surges associated with the storms, the UN’s Intergovernmental Panel on Climate Change said in a 594-page report today that examines weather impacts from Alaska to Africa and Australia.

Coastal areas around the world, especially large cities and small islands, are particularly vulnerable to the impact of climate change and as much as $35 trillion, or 9 percent of projected global economic output in 2070, may be exposed to climate-related hazards in ports, the panel said. That may increase the need for migration, according to the authors.

Here's the latest from ClimateProgress:

IPCC’s Planned Obsolescence: Fifth Assessment Report Will Ignore Crucial Permafrost Carbon Feedback!

A key reason the Intergovernmental Panel on Climate Change keeps issuing instantly irrelevant reports is that it keeps ignoring the latest climate science. We have known for years that perhaps the single most important carbon-cycle feedback is the melting of the permafrost.

Yet a must-read new United Nations Environment Programme report, “Policy Implications of Warming Permafrost” reports this jaw-dropping news:

"The effect of the permafrost carbon feedback on climate has not been included in the IPCC Assessment Reports. None of the climate projections in the IPCC Fourth Assessment Report include the permafrost carbon feedback (IPCC 2007). Participating modeling teams have completed their climate projections in support of the Fifth Assessment Report, but these projections do not include the permafrost carbon feedback. Consequently, the IPCC Fifth Assessment Report, due for release in stages between September 2013 and October 2014, will not include the potential effects of the permafrost carbon feedback on global climate."

Presumably that means that methane hydrates are not included either.
