More than 100 Arctic wildfires burn in worst-ever fire season – Smoke plumes from huge blazes in Greenland, Siberia, and Alaska visible from space – “These are some of the biggest fires on the planet, with a few appearing to be larger than 100,000 hectares”

By Edward Helmore 26 July 2019 (The Guardian) – The Arctic is suffering its worst wildfire season on record, with huge blazes in Greenland, Siberia, and Alaska producing plumes of smoke that can be seen from space. The Arctic region has recorded its hottest June ever. Since the start of that month, more than 100 wildfires have […]

The full scoop on Europe’s historic onslaught of heat – At least five nations had highest temperatures on record – Hottest day ever observed at hundreds of locations

By Bob Henson 26 July 2019 (Weather Underground) – Temperatures on Friday soared above 40°C (104°F) in Germany for an unprecedented third day in a row—and that’s just one in a mind-boggling swarm of all-time heat records set across western and northern Europe this week. At least five nations saw their highest temperatures on record, […]

Pesticide exposure causes bumblebee flight to fall short – “The negative effects of pesticide exposure on flight endurance have the potential to reduce the area that colonies can forage for food”

By Hayley Dunning 30 April 2019 (Imperial College London) – Bees exposed to a neonicotinoid pesticide fly only a third of the distance that unexposed bees are able to achieve. Flight behaviour is crucial for determining how bees forage, so reduced flight performance from pesticide exposure could lead to colonies going hungry and pollination services […]

Nutrient loading lowers resistance to thermal stress in Florida Keys corals – “These data make clear that this is not an ‘either temperature or nutrients’ situation, but rather a ‘both/and’ combination of multiple stressors”

By Gisele Galoustian 15 July 2019 (FAU) – Coral reefs are considered one of the most threatened ecosystems on the planet and are dying at alarming rates around the world. Scientists attribute coral bleaching and ultimately massive coral death to a number of environmental stressors, in particular, warming water temperatures due to climate change. A […]

All-time heat records melt in Europe – Paris warmer than Singapore at 42.6°C (108.7°F) – National records broken on Wednesday fell again on Thursday – “‘If you’d have said five years ago we’d see temperature records fall this frequently, I wouldn’t have believed you”

By William Wilkes and Megan Durisin 24 July 2019 (Bloomberg) – Europe’s latest summer heatwave broke heat records just weeks after the continent had its hottest ever June, fueling concern that a shifting climate is triggering more extreme weather. Germany probably set a new all-time temperature record of 42.6 degrees Celsius (108.7 Fahrenheit) in the […]

Rare rhinos among more than 200 animals killed by devastating India floods

GUWAHATI, 24 July 2019 (AFP) – Devastating floods have killed more than 200 wild animals—including 17 threatened one-horned rhinos—in one of India’s best-known national parks, officials said Wednesday. Forty percent of Kaziranga National Park in Assam has been left under water following 10 days of torrential rains that have also killed more than 71 people […]

By 2050, many cities will have weather like they’ve never seen – “The fate of major tropical cities remains uncertain as many will experience unprecedented climate conditions”

By Stephen Leahy 10 July 2019 (National Geographic) – Climate forecast for 2050: New York City winters will have the weather of today’s Virginia Beach, damp and cold London will be hot and dry like Barcelona, wet Seattle will be like drier San Francisco, and Washington D.C. will be more like today’s Nashville but with […]

It is probably too late to stop dangerous global warming – “The hard truth is that we are not on track”

By Sam Arie 17 July 2019 (Financial Times) – Few things should make you as optimistic — or as pessimistic — as the rise of renewable energy. Optimism comes from a new sense of urgency as the UK, Germany, and Spain set record highs for use of wind and solar power, and record lows for […]

Potomac River hits record high temperature of 34°C (94°F) after weeks of relentless heat

24 July 2019 (AFP) – The Potomac River, which flows through the US capital Washington, hit a record high temperature of 94 degrees Fahrenheit (34 degrees Celsius) over the weekend—as warm as bathwater—following a major heat wave. The previous highs came in the summers of 2011 and 2012, though record keeping began only in 2007. […]
