Thousands pray for rain in Indonesia as forests go up in smoke – “We’re doing everything we can, now we pray to Allah for the rain”

By Gayatri Suroyo and Jessica Damiana 11 September 2019 JAKARTA (Reuters) – Thousands of Indonesians prayed for rain in haze-hit towns on the islands of Sumatra and Borneo on Wednesday, as forest fires raged at the height of the dry season, the state Antara news agency reported. Fires have burnt through parts of Sumatra and […]

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) […]

Large rivers of melting water form on an ice sheet in western Greenland on 1 August 2019 and drain into moulin holes that empty into the ocean from underneath the ice. The heat wave that smashed high temperature records in five European countries a passed over Greenland, accelerating the melting of the island's ice sheet and causing massive ice loss in the Arctic.

Bizarre happenings in the Arctic: Lightning, tropical moisture, and more

By Bob Henson 14 August 2019 (Weather Underground) – You’ll have to forgive the Arctic. It’s had a rough summer. Sea ice is running neck and neck with 2012 for the lowest values on record for this time of year. Wildfires are ringing the Arctic, pouring more carbon dioxide into the air than in any comparable period in 17 […]

Remote sensing imagery of discolored water and algal blooms in the Florida Bay and the Florida Keys region between 1992 and 2013 showing connectivity of the mainland and the lower Florida Keys, all outlined in red. (a) Landsat true color image on 29 May 1992 shows turbid water in western Florida Bay and discolored, black water in central Florida Bay that extends southward to the lower Florida Keys; (b) AVHRR reflectance image on 12 March 1996 shows high turbidity from the Shark River Slough plume extending beyond the lower Florida Keys towards Dry Tortugas; (c, d) VIIRS chlorophyll a anomaly images show phytoplankton blooms off Shark River Slough reaching the lower Florida Keys that were partially composed of the cyanobacterium, Synechococcus, on (c) 24 November 2013 and (d) 27 January 2014.

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 […]

Image of the Day: Satellite view of deforestation in Peru’s Madre de Dios region

By by Andrea Nicolau, Andi Thomas, and Leah Kucera 18 April 2019 (NASA) – Considered a hotspot for biodiversity, the Madre de Dios region of southeastern Peru is an exceptionally fertile landscape. Standing at the edge of the Amazon basin, Madre de Dios has a rich concentration of endemic species—plants and animals that are found nowhere […]

North Atlantic Ocean phytoplankton decline coincides with warming temperatures over the last 150 years – “10 percent of the marine food base in this region has been lost over the industrial era”

North Atlantic Ocean phytoplankton decline coincides with warming temperatures over the last 150 years – “10 percent of the marine food base in this region has been lost over the industrial era”

By Jennifer Chu 6 May 2019 (MIT News) – Virtually all marine life depends on the productivity of phytoplankton — microscopic organisms that work tirelessly at the ocean’s surface to absorb the carbon dioxide that gets dissolved into the upper ocean from the atmosphere. Through photosynthesis, these microbes break down carbon dioxide into oxygen, some […]

Reducing air pollution may worsen droughts globally – “It’s mind boggling. There is a really clear signal of the effects of human greenhouse gases on the hydroclimate.”

By James Temple1 May 2019 (Technology Review) – Climate change is clearly making some regions wetter and others drier. But it’s been difficult for scientists to detect a clear, consistent human role in increasing the frequency and severity of global droughts given natural climate variability, regional differences, and limited data. A new report in Nature adds evidence […]

Due to humans, extinction risk for 1,700 animal species to increase by 2070 – “Losses in species populations can irreversibly hamper the functioning of ecosystems and human quality of life”

By Kendall Teare 4 March 2019 (Yale News) – As humans continue to expand our use of land across the planet, we leave other species little ground to stand on. By 2070, increased human land-use is expected to put 1,700 species of amphibians, birds, and mammals at greater extinction risk by shrinking their natural habitats, […]
