Histograms of daily maximum wet-bulb temperature, TWmax (°C), and maps of the ensemble averaged 30-year TWmax. (A) The histograms are generated for the most populous cities in the selected regions for each scenario: HIST (blue), RCP4.5 (green), and RCP8.5 (red). Values within each panel correspond to the 2- and 25-year return period of the bias-corrected annual maxima of TWmax, and the x and y axes indicate TWmax (°C) and the number of occurrences on a logarithmic scale, respectively. The background image was obtained from NASA Visible Earth. (B to D) The spatial distributions of bias-corrected ensemble averaged 30-year TWmax for each GHG scenario: HIST (1976–2005) (B), RCP4.5 (2071–2100) (C), and RCP8.5 (2071–2100) (D).

Climate change to cause humid heatwaves that will kill even healthy people

By Damian Carrington 2 August 2017 (The Guardian) – Extreme heatwaves that kill even healthy people within hours will strike parts of the Indian subcontinent unless global carbon emissions are cut sharply and soon, according to new research. Even outside of these hotspots, three-quarters of the 1.7 billion population – particularly those farming in the Ganges […]

The world is about to install 700 million air conditioners – “Demand for cooling, particularly in hot climates, is going to be an incredible driver of electricity requirements”

By Chris Mooney and Brady Dennis 31 May 2016 (Washington Post) – As summer temperatures finally settle in, many in the United States take it for granted that they can dial down the thermostat: Americans use 5 percent of all of their electricity cooling homes and buildings. In many other countries, however — including countries […]

The deadly combination of heat and humidity

By Robert Kopp, Jonathan Buzan, and Matthew Huber 6 June 2015 (The New York Times) – The most deadly weather-related disasters aren’t necessarily caused by floods, droughts or hurricanes. They can be caused by heat waves, like the sweltering blanket that’s taken over 2,500 lives in India in recent weeks. Temperatures broke 118 degrees in parts […]

Local CFA firefighter David Tree shares his water with an injured Australian koala at Mirboo North after wildfires swept through the region, 9 February 2009. The koala, later named “Sam” suffered second- and third-degree burns to her paws in the February fires and is recovering at the Southern Ash Wildlife Shelter in Victoria state.

Remembering Australia’s Black Saturday 2009

9 January 2013 (Desdemona Despair) – In February 2009, Desdemona was new to blogging. The world was still reeling from the global financial collapse caused by the deregulated, automated, shadow banking system – currently valued at $67 trillion and growing! Global warming was fading into the background of the public consciousness. Except in Australia, where […]

How global climate change may affect violence

July 18, 2010 (NNPA) – If global warming is a scientific fact, then we’d better be prepared for the earth to become a more violent place. That according to a recent Iowa State University study that shows as the earth’s average temperature rises, so too does violent tendencies in humans. Using U.S. government data on […]
