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…
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…
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…
Dr. Indur Goklany writes: Earlier today on WUWT in the post, UHI and Heat Related Mortality, a researcher from Arizona claims that, “Extreme heat is the leading weather-related killer in the United States.” I am afraid that this piece of nonsense is about to become conventional wisdom. However, this is based on cherry-picking one’s data…
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…
You may remember headlines like these last summer: With Blow-Out March Heat Wave, Meteorologist Masters Says ‘This is not the atmosphere I grew up with’ The 2012 Heat Wave: “Almost Like Science Fiction” | Popular Science Record Heat Wave Pushes U.S. Belief in Climate Change to 70% US heatwave may have been made more likely by global warming … Global Warming May Have Fueled March…
More examples of the nighttime heat sink effect of UHI. Asphalt, concrete, bricks and other infrastructure holds the energy from daytime solar insolation and releases it at night as LWIR. Anyone who has ever stood next to a sun illuminated brick wall after sunset can understand this. The authors talk about the temperature record at…
