35 years of climate change in one video

By Johnny Wood 18 November 2019 (WEF) – Q: If you subtract 95 percent from something, what’s left? A: An environmental crisis. The “something” in question is the oldest and thickest solid layer of frozen water in the Arctic Ocean, which is melting so rapidly that just 5% of its original mass remains. Scientists from the […]

This animation depicts the abundance and direction of black carbon blowing through the atmosphere from 1 November 2019 to 18 November 2019. The data for the animation come from the GEOS forward processing (GEOS-FP) model, which assimilates information from satellite, aircraft, and ground-based observing systems.

Smoke plumes from Australia bushfires crossing oceans

By Michael Carlowicz and Adam Voiland 21 November 2019 (NASA) – Three weeks into November 2019, springtime bush fires continued to blaze across southern and eastern Australian states. As of November 20, government agencies counted 45 fires in South Australia and 49 in New South Wales, and dangerously dry and windy weather was fanning flames […]

Devastating bushfire conditions to worsen in Australia – “Until we get significant rainfall, the fires will not go out”

By Lidia Kelly 17 November 2019 MELBOURNE (Reuters) – Rising temperatures, lightning strikes and erratic winds are set to fan wildfires in Australia in the week ahead, officials said on Sunday, with emergency crews already working day and night to contain more than 130 blazes. The state of New South Wales, where 367 homes have […]

Arctic shifts to a carbon source due to winter soil emissions – “The warmer it gets, the more carbon will be released into the atmosphere from the permafrost region, which will add to further warming”

By Samson Reiny 8 November 2019 (NASA) – A NASA-funded study suggests winter carbon emissions in the Arctic may be adding more carbon into the atmosphere each year than is taken up by Arctic vegetation, marking a stark reversal for a region that has captured and stored carbon for tens of thousands of years. The […]

NASA finds Typhoon Bualoi rapidly intensified

By Rob Gutro 21 October 2019 (NASA) – Typhoon Bualoi rapidly intensified over 24 hours and quickly developed an eye and powerful thunderstorms. On 21 October 2019, the eye of Typhoon Bualoi was just over 50 miles from the island of Saipan when NASA-NOAA’s Suomi NPP satellite passed overhead. Saipan is the largest island of […]

Record heatwave and extreme drought reveal lost “Spanish Stonehenge”

By Kasha Patel 19 September 2019 (NASA) – In 1963, the Spanish government under Francisco Franco built the Valdecañas Reservoir in order to bring water and electricity to underdeveloped parts of western Spain. However, the creation of the reservoir flooded some inhabited areas as well as large stone (megalithic) monuments. After fifty years underwater, one […]

Drought exacerbates wildfires in Australia rainforest

By Michael Carlowicz 14 September 2019 (NASA) – Fire season in the Australian states of Queensland and New South Wales got off to an early and ugly start in September 2019. Fueled by a long and deepening drought, more than 100 fires burned in forest and bush areas near the southeast coasts, including some subtropical […]

Summer 2019 in the Northern Hemisphere tied for warmest summer on record – Five hottest NH summers have occurred in the past five years

By Andrew Freedman 16 September 2019 (The Washington Post) – The Northern Hemisphere just had its hottest summer on record since 1880, according to National Oceanic and Atmospheric Administration data released Monday. NOAA found the average global surface temperature taken by thousands of thermometers, buoys and other sensors on land and sea tied with that of 2016 […]

NASA satellites confirm Amazon rainforest is burning at a record rate

By Passant Rabie 27 August 2019 (Space.com) – As raging fires continue to sweep through the Amazon rainforest in Brazil, NASA satellites and astronauts aboard the International Space Station are tracking the flames from above. Their view confirmed that this is the most active fire year in Brazil since 2010. Fire detections by NASA’s Moderate Resolution Imaging Spectroradiometer (MODIS) […]

Hurricane Dorian strikes Bahamas with record fury as Category 5 storm – “The winds are howling like we’ve never, ever experienced before”

By Ramón Espinosa 1 September 2019 McLEAN’S TOWN CAY, Bahamas (AP) – Hurricane Dorian struck the northern Bahamas as a catastrophic Category 5 storm Sunday, its record 185 mph winds ripping off roofs, overturning cars and tearing down power lines as hundreds hunkered down in schools, churches and shelters. Dorian slammed into Elbow Cay in […]
