Oh noes! Exposure of US population to extreme heat could quadruple by mid-century

From the National Center for Atmospheric Research/University Corporation for Atmospheric Research and the Department of “ignored data in favor of modeled simulations” comes this claim from Trenberth’s mountain climate alarm lair. Only one problem: actual data on U.S. Temperature Extremes does not support the claim. See below. Interaction of warming climate with a growing, shifting…

Claim: If no action is taken, extreme heat waves will become the norm by the end of the century

From the Joint Research Center: Analysing heat waves – new index allows predicting their magnitude JRC scientists have developed a new index to measure the magnitude of heat waves, in cooperation with colleagues from five research organisations. According to the index projections, under the worst climate scenario of temperature rise nearing 4.8⁰C, extreme heat waves…

The ‘strawman’ albedo effect

From ETH Zurich , something that actually makes sense. Straw albedo mitigates extreme heat Wheat fields are often tilled immediately after the crop is harvested, removing the light-coloured stubble and crop residues from the soil surface and bringing dark bare earth to the top. Post-harvest tilling is a widely practised and common management technique in…

Climate Change, Heat Waves, and Adaptation

By Paul C. “Chip” Knappenberger and Patrick J. Michaels The main idea, as it is portrayed, driving the Obama administration’s pursuit of carbon dioxide regulations is that climate change is leading to all manner of bad things. Pointing to concrete example of bad things that have resulted from human greenhouse gas emissions, however, is much…

Australian heatwaves are nothing new

Guest essay by Viv Forbes No doubt we will hear how the current heatwaves in Australia are “unprecedented” and evidence of dangerous man-made global warming. They are neither “global” nor “unprecedented”. In the great heatwave of 1896, with nearly 200 deaths, the temperature at Bourke did not fall below 45.6 degC for six weeks, and…
