New NSF paleo research claiming Arctic was warmer fails to take major ocean circulation changes 3 million years ago into account

I covered this story earlier today, and it was presented much differently in that press release. This press release takes a different tack. IMHO, it looks like a big “ooops” from the National Science Foundation. See what I found after the jump on why I think they didn’t perform due diligence on this research –…

More 'ice free Arctic' claims – we've heard it all before

From the University of Massachusetts at Amherst, something we’ve heard before. For example this claim from 2008. Gotta love the use of props to show how climate tipping points work: NASA: Arctic Ocean Could be Mostly Ice Free in 2013 Apr 4, 2008 “The sea ice is decreasing faster than all the models predicted,” says…

The curious case of rising CO2 and falling temperatures

Guest essay by Tony Brown Some readers might recall my recent article ‘The Long Slow Thaw?’ In this I reconstructed Central England temperature to 1538 from its current instrumental date of 1659. I was surprised by two notable periods of warmth around 1630 and 1530. I am indebted amongst other material, to Phil Jones excellent…

Temperature change in perspective

Guest post by Ed Hoskins The UK Met Office long term Central England Temperature record[1] has kept a continuous and consistent data set since the 1660s. It appears to be reliable and to have maintained its quality. It has not been adjusted as have so many other official temperature records.Although the CET record covers only…

Future shifts in rainfall

From UC Berkeley: Rising temperature difference between hemispheres could dramatically shift rainfall patterns in tropics By Robert Sanders, Media Relations  BERKELEY — One often ignored consequence of global climate change is that the Northern Hemisphere is becoming warmer than the Southern Hemisphere, which could significantly alter tropical precipitation patterns, according to a new study by…

From UAH – Global Temperature Report: January 2013

Second warmest January in past 35 Global climate trend since Nov. 16, 1978: +0.14 C per decade January temperatures (preliminary) Global composite temp.: +0.51 C (about 0.92 degrees Fahrenheit) above 30-year average for January. Northern Hemisphere: +0.55 C (about 0.99 degrees Fahrenheit) above 30-year average for January. Southern Hemisphere: +0.46 C (about 0.83 degrees Fahrenheit)…

Global Temperature Updates – 2012

By Paul Homewood While Obama is imploring us to stop the global warming that is bringing us “the devastating impact of raging fires, and crippling drought, and more powerful storms”, it would seem to be a good idea to see exactly what global temperatures have been doing in the last year. December Updates First, let’s…
