Some people say that C02 does not cause warming - recent rising temperatures are due to natural factors such as solar cycles. Others think there is a lot less global warming than the propaganda proclaims - the data has been massaged by various means to create an 'illusion' of rising temperatures. Still others accept C02 as a greenhouse gas and that as such it warms the planet - but the models labour under a false assumption and that is the idea of feedback. C02 causes greater warmth which causes more water to evaporate from the oceans - and adds to the warmth.

A Climate Change Most Foul
At http://wattsupwiththat.com/2011/04/09/the-pre-climategate-issue-that-is-... is Anthony Watts take on a piece of McIntyre sleuthing that can be view in full at http://climateaudit.org/2011/04/09/yamal-and-hide-the-decline/ which is the full disclosure of what was going on behind the scenes to upset the HADCru whistle blower leading up to the Climategate email leak about 18 months ago. In the News was covering the Yamal tree ring story as developed at the time by McIntyre.
Charlatans
Piers Corbyn, on April 5th, said that during the period April 6-9th there was a threat of a major earthquake - and this duly happened, in Mexico. This follows earlier predictions of earthquake activity that came to pass in Japan, Thailand and New Zealand. People are beginning to sit up and notice - especially when he suggests western North America is vulnerable. Corbyn's methodology involves luni-solar cycles, or astrology as AGW alarmists decried after he successfully predicted the blizzards of 2009. Seems there are a lot of charlatans out there.
Arctic Ocean Ponding
At www.sciencenews.org/view/generic/id/72214/title/Arctic_Ocean_hosts_wierd... which is caused by rivers emptying from Siberia into the Arctic Ocean in combination with the sea ice that accumulates there during the dark winters and large amounts of which melt during the summer months. Hence, the Ocean has pooled, as the saying goes, failing to mix fresh with salty waters from further afield. It is the pattern of circular polar winds that have corralled a huge pond of fresh water within the Beaufort Gyre off northern Canada.
Inuit Oil Barons to be ... cold weather in the 18th century
At www.physorg.com/print221195120.html ... it seems oil geologists are looking seriously at Greenland for untapped reserves of the black sticky substance. As can be expected the environmentalists are not very happy about this - they want oil to run out. Oil extraction is dubbed exploitation of the environment - which says it all. Unfortunately,as far as Greenland is concerned the lobby has soiled the patch. The Inuit do not have fond memories of Greenpeace and their soulmates as they campaigned to stop seal hunting - and Inuit are the major population group of Greenland.
Ozone Hole
The ozone hole above the Arctic has got the doomsayers red around the ears. It is the subject of reports at www.sciencenews.org/view/generic/id/72206/title/Record_Arctic_ozone_mini... and www.sciencedaily.com/releases/2011/04/110405102202.htm 'Record depletion of Arctic ozone layer causing increased uv radiation in Scandinavia' and at http://wattsupwiththat.com/2011/04/05/arctic-ozone-hole-in-march/ - in the Science News story the hole is actually a thinning - quite different.
Climate papers ... early April
At http://wattsupwiththat.com/2011/04/04/claim-nuclear-tests-stopped-global... - one of the bugbears to global warming theory is the fact the earth cooled from the 1940s to the late 1970s - and here is a paper from the Journal of Atmospheric and Solar-Terrestrial Physics April 2011 that claims it was due to the testing and detonation of nucleur devices in the 1950s and 1960s. When reading claims like these one wonders why they have to scratch the depths - if AGW was taking place it would be self evident without embroiderment.
North Atlantic Weather
At www.sciencedaily.com/releases/2011/03/110330131306.htm scientists have been finding out why it is cold in NE America but not in NW Europe at the same latitude (a paper in Nature, March 31st 2001). It is 10 degrees Fahrenheit warmer in NW Europe than it is on the opposite side of the Atlantic. It seems the same thing occurs in the Pacific where winters in the Vancouver and Seattle region are mild in comparison with the same latitude on the eastern side of the ocean.
Climate Update as we head towards the end of March
Over at www.weatheraction.com Piers Corbyn is predicting some extreme weather or even an earthquake in the next few days - as a result of solar activity. Meanwhile, at www.physorg.com/print220262708.html we learn that sea ice extent is at nearly its lowest point - ever (or since the modern AGW phenomenon took root some 25 to 30 years ago). However, at http://stevengoddard.wordpress.com/2011/03/25/huge-increase-in-thick-ice... where we learn the opposite side of things. It is not the extent that matters, it is being argued, but the thickness of the ice.
The Earth is Greening
At http://wattsupwiththat.com/2011/03/24/the-earths-biosphere-is-booming-da... ... global warming or not the earth's biosphere appears to be benefiting from increased C02 in the atmosphere - the earth is greening. This post is based on one paper by three Chinese scientists, Liu et al, 'Spatial and temperal variations of global LAI during 1981-2006' in the Journal of Geophysical Sciences 20 (2010) - the LAI in this instance stands for Leaf Area Index.
