New Study: Two Thousand Years of Northern European Summer Temperatures Show a Downward Trend

In a paper published in the Journal of Quaternary Science, Esper et al. (2014) write that tree-ring chronologies of maximum latewood density (MXD) “are most suitable to reconstruct annually resolved summer temperature variations of the late Holocene.” And working with what they call “the world’s two longest MXD-based climate reconstructions” – those of Melvin et…

Guest Post by Willis Eschenbach Anthony has just posted the results from a “Press Session” at the AGU conference. In it the authors make two claims of interest. The first is that there has been a five percent decrease in the summer Arctic albedo since the year 2000: A decline in the region’s albedo –…

DECC Forced To Release Data Showing Impact Of Climate Policies On Energy Prices

By Paul Homewood http://www.telegraph.co.uk/news/earth/energy/11292367/Green-policies-to-add-up-to-40pc-to-cost-of-household-electricity.html Earlier I posted on the news that Department of Energy & Climate Change (DECC) tried to cover up official data showing how electricity prices are expected to skyrocket, as a direct result of climate policies. (See above Telegraph article). I’ve now had a chance to dissect this data. They base their…

Hump Day Hilarity – model the bouncing ball

Josh writes: Talking of Climate Models, there is another great Climate Audit post titled “Unprecedented” Model Discrepancy where Richard Betts, once again, provides cartoon inspiration in the comments. It’s a bit like watching a ball bouncing down a rocky hillside. You can predict some aspects of it behaviour but not others. You can predict it will…
