California’s drought tolerant landscaping may make heat waves worse

From USC and the evapotranspiration cools locally department: Hidden, local climate impacts of drought-friendly vegetation New research by USC Viterbi researchers explores the climate impact of drought vegetation efforts To address the recent drought in California, policymakers have created incentives for homeowners to replace existing lawns with drought tolerant vegetation. However, new research from George…

Study: Ocean temps predict US heat waves 50 days out

Pacific pattern often forms in advance of hot days in eastern US From the NATIONAL CENTER FOR ATMOSPHERIC RESEARCH/UNIVERSITY CORPORATION FOR ATMOSPHERIC RESEARCH BOULDER — The formation of a distinct pattern of sea surface temperatures in the middle of the North Pacific Ocean can predict an increased chance of summertime heat waves in the eastern…

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…
