Record downpour paralyzes Washington, D.C. with flash flood – “This event goes off the scale”

By Jason Samenow, Ian Livingston, and Jeff Halverson 8 July 2019 (The Washington Post) – A month’s worth of rain deluged the immediate D.C. area early Monday, resulting in one of its most extreme flooding events in years. The record-setting cloudburst unleashed four inches of water in a single hour, way too much for a […]

Trump officials deleting mentions of “climate change” from U.S. Geological Survey press releases – “It’s an insult to the science”

By Scott Waldman 8 July 2019 (Science) – A March news release from the U.S. Geological Survey (USGS) touted a new study that could be useful for infrastructure planning along the California coastline. At least that’s how President Donald Trump’s administration conveyed it. The news release hardly stood out. It focused on the methodology of […]

Unexpected consequences from catastrophic mangrove dieback – “What was concerning was that the dead mangrove forest emitted about eight times more methane than the living forest”

4 July 2019 (Southern Cross University) – When swathes of mangrove forests died along a 1000 kilometre stretch of coastline in northern Australia’s Gulf of Carpentaria, there was widespread shock. But the impacts of the catastrophic climate-induced mangrove dieback didn’t end there. In a world first, researchers from Southern Cross University have found that the […]

Global warming made record-breaking June 2019 European heatwave at least five times likelier – “This is a strong reminder again that climate change is happening here and now. It is not a problem for our kids only.”

By Damian Carrington 2 July 2019 (The Guardian) – The record-breaking heatwave that struck France and other European nations in June was made at least five – and possibly 100 – times more likely by climate change, scientists have calculated. Such heatwaves are also about 4C hotter than a century ago, the researchers say. Furthermore, the […]
