Caldeira slams anti-scientific witchhunts: “Are American politic. By Joe Romm on May 9, 2010 at 10:32 am "Caldeira slams anti-scientific witchhunts: “Are American politicians following in the footsteps of Stalin?”
" U-VA faculty Senate: Cuccinelli actions threaten “our ability to generate the knowledge upon which informed public policy relies.” Climate scientist Ken Caldeira commented on my recent post, “WashPost: University of Virginia should fight AG Cuccinelli’s faulty investigation of Michael Mann.” Since it’s well worth reading, I am reprinting it below — along with the powerful conclusion of the University of Virginia Faculty Senate Executive Council statement. I gave Caldeira a chance to edit his statement, since commenting does not always perfectly express one’s thoughts: U.S. National Academy of Sciences labels as “settled facts” that. Logical Science. Data.GISS: GISS Surface Temperature Analysis: 2011 Annual Analysis. Global Temperature in 2011, Trends, and Prospects By James Hansen, Reto Ruedy, Makiko Sato and Ken Lo — 18 January 2012 The annual 2011 surface air temperature anomaly relative to base period 1951-1980 is shown in Fig. 1 at both the 1200 km and 250 km resolutions of the GISS analysis (Hansen et al., 2010).
The global mean anomaly, averaged over the area with a defined anomaly is 0.51°C for 1200 km resolution and 0.44°C for 250 km resolution. The 1200 km resolution analysis, because it fills in estimated anomalies in Africa, Canada, Siberia, and especially in the Arctic, is believed to provide the better estimate for the full global anomaly, as discussed by Hansen et al. (2010) (note 1). Figure 1. Websites to monitor the Arctic Sea Ice. Posted on 28 May 2010 by michael sweet Guest post by Michael Sweet The Arctic melt season is starting to get into gear.
The ice really starts to melt in June and it'll be interesting to see what develops this year. This post is to describe some web sites I've found to be useful to monitor the summer ice melt in the northern hemisphere. They can also be used to track the Antarctic ice. Ice Safety. At the Canadian Ice Service (CIS), our mission is to provide the most accurate and timely information about ice in Canada's navigable waters. We work to promote safe and efficient maritime operations and to help protect Canada's environment. For the latest ice conditions, click the appropriate regional area on the map. Arctic Ocean | Western Arctic | Eastern Arctic | Hudson Bay | East Coast | Great Lakes. As Arctic sea ice shrinks faster than 2007, NSIDC director Serre. By Joe Romm on May 24, 2010 at 7:57 pm "As Arctic sea ice shrinks faster than 2007, NSIDC director Serreze says, “I think it’s quite possible we could “break another record this year.”
" Watts and Goddard seem in denial: “We are still about six weeks away from anything interesting happening in the Arctic.” The big climate news up north is the Arctic double stunner: Sea ice extent (area) is now below 2007 levels, while the even more important metric of ice volume hit a record low for March (according to the Polar Science Center). Data from both the Japan Aerospace Exploration Agency (JAXA) and National Snow and Ice Data Center (NSIDC) show Arctic sea ice extent shrinking below the level of 2007 at a rapid pace: Canada’s Globe and Mail headlines their story, “Arctic sea ice heading for new record low,” Arctic Sea Ice News & Analysis. While the U.S. experienced extreme weather in November, conditions in the Arctic were fairly ordinary.
Arctic sea ice in November followed a fairly average growth pace. Ice extent was near average over much of the Arctic with only the Chukchi Sea and Davis Strait showing below average ice conditions. Overview of conditions Figure 1. Arctic sea ice extent for November 2014 was 10.36 million square kilometers (4.00 million square miles). Polar Sea Ice Cap and Snow - Cryosphere Today. Latest GRACE data on Greenland ice mass. Posted on 28 May 2010 by John Cook I don't plan to fall into the trap of breathlessly reporting every twist and turn of short-term climate fluctuations (I went through a bit of a silly period in March and April 2008 ).
But we've been discussing Greenland trends and as it's been over a year since posting GRACE data on Greenland ice mass so I figure we're due an update. On temperature and CO2 in the past. Posted on 29 May 2010 by Riccardo Guest post by Riccardo One of the most famous paleoclimate graphs for "amateur climatologists" like me is the Vostok ice core reconstructions of temperature and CO2 concentration over the last 420 kyr.
It shows how nicely the two follow each other and that our climate has overall "oscillated" within two relatively well defined limits. One may wish to look at this correlation a little better. So let's take the Dome C ice core data which cover 800 Kyrs and plot temperature versus CO2 concentration. GISS: Science Briefs: Whither U.S. Climate? Whither U.S.

NOAA: Warmest May, spring, and Jan-May on record « Climate Progr. By Joe Romm on June 15, 2010 at 5:03 pm "NOAA: Warmest May, spring, and Jan-May on record" NOAA’s National Climatic Data Center has published its monthly “State of the Climate Report.”
The combined global land and ocean surface temperature was the warmest on record for May, March-May (Northern Hemisphere spring-Southern Hemisphere autumn), and the period January-May. The warming in May is greatest precisely where climate science suggested it would be — the high northern latitudes (see “What exactly is polar amplification and why does it matter?” — precisely the worst possible place from the perspective of amplifying feedbacks (see “Tundra 4: Permafrost loss linked to Arctic sea ice loss“): Disputing the ‘consensus’ on global warming « Climate Progress. By Joe Romm on June 16, 2010 at 3:49 pm "Disputing the ‘consensus’ on global warming" Science is in many ways the opposite of decision by consensus.
I have never liked the use of the word “consensus” as it is typically applied in the climate arena. Global Warming and Climate Change skepticism examined. NOAA Climate Services.
