New Evidence Undermines Climate Alarmism

With high-altitude mountains in Himachal Pradesh experiencing up to 100 cm fresh snowfall in November month after 10 years, the abundance of snow on mountains has rejuvenated nearly one thousand Himalayan glaciers and has ensured uninterrupted supply of water for drinking, irrigation and hydel projects. While scanty snowfall and rising temperature in the last decade had sparked the possibilities of fast shrinking of glaciers, good spells of snowfall in last three years have changed the trend with glaciers almost growing to their original size. –Suresh Sharma, The Times of India, 3 December 2012

A new analysis of data from dedicated satellites shows that one of the main factors predicted to drive rising sea levels in future has been seriously overestimated, with major implications for climate talks currently underway in Doha. –Lewis Page, The Register, 28 November 2012

When the Atlantic hurricane season starts next June 1, it will have been 2,777 days since the last time an intense (that is a Category 3, 4 or 5) hurricane made landfall along the US coast (Wilma in 2005). Such a prolonged period without an intense hurricane landfall has not been observed since 1900. The long-term intense hurricane drought means that a mere “regression to the mean” will see more hurricane landfalls and considerably higher damage in the years to come. The fashionable talk these days of a “new normal” is of course utter bullsh*t. Just wait until we return to the “old normal” — I know that it may be hard to believe, but both hurricane damage and climate hype are set to increase dramatically in the years to come. –Roger Pielke Jr., 3 December 2012

When the worst drought in 60 years hit America’s corn belt this summer, many people wondered if it was caused by climate change. It is too early to say much about such a recent episode but various studies have attributed earlier individual heatwaves or drought to global warming, notably those in Europe in 2003, Russia in 2010 and the sweltering summer of 2011 in Texas. The most recent (2007) assessment by the Intergovernmental Panel on Climate Change (IPCC) said bluntly: “higher temperatures and decreased precipitation have contributed to changes in drought.” Global warming might cause drought because warm air holds on to water vapour, making rain even less likely in places that are already dry. But a study published recently in Nature casts doubt about whether that is actually happening. –The Economist, 1 December 2012

A paper published today in The Journal of Climate reconstructs snow accumulation of the Greenland ice sheet from 1600-2009 and finds “a 12% or 86 Gigaton/yr increase in ice sheet accumulation rate from the end of the Little Ice Age in ~1840 to the last decade of the reconstruction. This 1840-1996 trend is 30% higher than that of 1600-2009, suggesting an accelerating accumulation rate.” –The Hockey Schtick, 6 December 2012
