EXCEPTIONS THAT DISPROVE THE AGW 'RULE'

Joanne Nova and Anthony Cox highlight a number of papers in this article at Online Opinion that demonstrate exceptions to the 'established' orthodoxy of AGW as provided by the consensus view.

"The following papers clarify AGW's uncertainty between forcings and feedbacks and show that AGW science is not clear about the distinction or effects. The papers show the IPCC assumptions about the role of CO2 and water vapor, particularly in the form of clouds, are incorrect and that the IPCC conclusions about global average temperature are both exaggerated and wrong".

GLACIERS RETREATED 6 TIMES FASTER 80 YEARS AGO

Anthony Watts at his website highlights a paper that finds alpine glaciers in Glacier National Park, Montana retreated up to 6 times faster during the 1930′s and 1940′s than over the past 40 years.

NASA'S RUBBER RULER

Is there an official long-term temperature dataset that has not been updated/homogenized?

Is it statistically plausible that every 'updated' dataset would lead to an increased warming trend?

Randall Hoven writes at The American Thinker website:

"A funny thing happened on the way to determining how hot 2012 has been on a global basis: temperatures changed in 1880.

We've been hearing that 2012 has been the "hottest on record." I had written earlier that those claims were based on the contiguous United States only, or 1.5% of the earth's surface. The "global temperature" in 2012 through June was only the 10th hottest on record. In fact, every single month of 1998 was warmer than the corresponding month of 2012".

BETTER CLIMATE MODELS NEEDED

The journal Nature editorialises about attributing weather events to climate change.

"Attribution is the attempt to deconstruct the causes of observable weather and to understand the physics of why extremes such as floods and heatwaves occur. This is important basic research. Extreme weather and changing weather patterns — the obvious manifestations of global climate change — do not simply reflect easily identifiable changes in Earth’s energy balance such as a rise in atmospheric temperature".

MEDIA COVERAGE OF ARCTIC SEA ICE EXTENT VERY EXTENSIVE

Of no surprise to many, the media coverage of extensive Arctic sea ice decline has been all pervasive while reporting of growing Antarctic sea ice extent has been fairly minimal.

Matt Ridley in the Wall Street Journal acknowledges the Arctic sea ice decline and queries the causes while James Taylor at Forbes highlights the increasing extent of Antarctic ice.

DID THE GLOBAL TEMPERATURE TREND CHANGE IN THE 1990s?

Dr Tom Quirk in this article in the Asia-Pacific Journal of Atmospheric Sciences looks at temperature trends.

"The apparent leveling of the global temperature time series at the end of the 1990s may represent a break in the upward trend. A study of the time series measurements for temperature, carbon dioxide, humidity and methane shows changes coincident with phase changes of the Atlantic and Pacific Decadal Oscillations. There are changes in carbon dioxide, humidity and methane measurement series in 2000. If these changes mark a phase change of the Pacific Decadal Oscillation then it might explain the global temperature behaviour".
