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: Last week, the University of Virginia Faculty Senate Executive Council issued a “Position Statement on Attorney General’s Investigation of Dr. 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.

Arctic Ocean | Western Arctic | Eastern Arctic | Hudson Bay | East Coast | Great Lakes Full Resolution Map | Animated Map (last 10 days) This map displays the latest ice cover in Canadian waters. To learn more about our products and how to interpret them, take a look at our Ice Products Guide. As Arctic sea ice shrinks faster than 2007, NSIDC director Serre. 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. Many thanks to Tenney Naumer of Climate Change: The Next Generation who emailed me the graph. Thanks also to John Wahr at the University of Colorado who analysed the GRACE data and granted permission to reproduce it here. Figure 1 below shows the latest satellite gravity measurements of the Greenland ice mass, through to February 2010 This graph includes 12 months more data than Velicogna 2009 and shows the rate of ice mass loss is still increasing. </i>*} What we find is over a longer time period, Greenland was in approximate mass balance in the early 1990s. 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. GISS: Science Briefs: Whither U.S. Climate? Whither U.S.
Climate? By James Hansen, Reto Ruedy, Jay Glascoe and Makiko Sato — August 1999 What's happening to our climate? Was the heat wave and drought in the Eastern United States in 1999 a sign of global warming? Empirical evidence does not lend much support to the notion that climate is headed precipitately toward more extreme heat and drought. Monckton Chronicles Part IV– Medieval Warm Period?

Skeptical Science: Examining Global Warming Skepticism. 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.
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. Scientists don’t really have a ‘consensus’ so much as they have an ‘understanding‘ of climate science. Global Warming and Climate Change skepticism examined. NOAA Climate Services.
