EPA suspends enforcement of environmental laws indefinitely at request of petroleum industry – “The EPA uses this global pandemic to create loopholes for destroying the environment”

By Rebecca Beitsch 26 March 2020 (The Hill) – The Environmental Protection Agency (EPA) issued a sweeping suspension of its enforcement of environmental laws Thursday, telling companies they would not need to meet environmental standards during the coronavirus outbreak. The temporary policy, for which EPA has set no end date, would allow any number of […]

Satellite images show less pollution over the U.S. as coronavirus shuts down public places

By Madeline Holcombe and Sean O’Key 23 March 2020 (CNN) – As millions of Americans are kept from work, school and most public places as coronavirus is on the rise, satellite images show pollution on the decline.Images taken over the first three weeks of March show less nitrogen dioxide over parts of the United States than […]

Pollution from tire wear 1,000 times worse than exhaust emissions

OXFORD, 6 March 2020 (Emissions Analytics) – Pollution from tyre wear can be 1,000 times worse than what comes out of a car’s exhaust, Emissions Analytics has found. Harmful particle matter from tyres – and also brakes – is a very serious and growing environmental problem, one that is being exacerbated by the increasing popularity […]

University of Rochester researchers in Greenland drill for ice cores, which contain air bubbles with small quantities of ancient air trapped inside. By measuring the carbon-14 isotope in air from more than 200 years ago, the researchers found that scientists have been vastly overestimating the amount of fossil methane emitted by natural sources, and have therefore been underestimating the amount of methane humans are emitting into the atmosphere via fossil fuels.

Methane emitted via human fossil fuel use “vastly underestimated”

By Lindsey Valich 19 February 2020 (University of Rochester) – Methane is a powerful greenhouse gas and large contributor to global warming. Methane emissions to the atmosphere have increased by approximately 150 percent over the past three centuries, but it has been difficult for researchers to determine exactly where these emissions originate; heat-trapping gases like […]

Carbon emissions (CO2e) from different modes of transportation. Non-pooled ride hailing, like with Uber and lyft, emits the most carbon, by a wide margin. Graphic: UCS

Taking an Uber or Lyft pollutes more than driving, California finds – “For a one-mile trip, on average there’s another 0.7 miles of driving around to deliver that trip”

By Tony Barboza 7 March 2020 (Los Angeles Times) – Behind the tap-of-your-phone convenience of hailing an Uber or Lyft lies an inconvenient truth: Such rides generate more carbon emissions than simply driving yourself. The increased pollution comes primarily from “deadheading,” that is, drivers traveling to pick up a passenger or cruising the streets while […]

Sandstorm wreaks havoc in Canary Islands, worst such storm to hit the islands in 40 years – “I’m old enough to know all about the calima, but I don’t recall it that strong. Everything just turned red.”

By Raphael Minder 24 February 2020 MADRID – Winds from the Sahara continued to send streams of sand drifting over the Canary Islands on Monday, creating chaos as the swirling sands forced planes to be grounded, disrupted traffic and exacerbated wildfires. Ángel Víctor Torres, the regional president of the islands, a Spanish archipelago, told Spanish […]

These maps show nitrogen dioxide (NO2) values across China from 1 January 2020 to 20 January 2020 (before the quarantine) and 10 February 2020 to 25 February 2020 (during the quarantine). The data were collected by the Tropospheric Monitoring Instrument (TROPOMI) on ESA’s Sentinel-5 satellite. A related sensor, the Ozone Monitoring Instrument (OMI) on NASA’s Aura satellite, has been making similar measurements. Graphic: Joshua Stevens / NASA Earth Observatory

Airborne nitrogen dioxide plummets over China as quarantine shuts down industry

By Kasha Patel 28 February 2020 (NASA) – NASA and European Space Agency (ESA) pollution monitoring satellites have detected significant decreases in nitrogen dioxide (NO2) over China. There is evidence that the change is at least partly related to the economic slowdown following the outbreak of coronavirus. At the end of 2019, medical professionals in […]

Graph of the Day: The Future of Ocean Acidification

18 December 2019 (NOAA) – New research by NOAA, the University of Maryland, and international partners published in Nature Scientific Reports shows that the changing chemistry of seawater has implications for continued greenhouse gas absorption. The ocean has been playing an important role in helping slow down global climate change by removing the greenhouse gas carbon dioxide […]

Hundreds of billions of locusts, fueled by conflict and climate change, are swarming East Africa – 400-fold increase in their numbers by June 2020 projected

By Madeleine Stone 14 February 2020 (National Geographic) – East Africa is in the midst of a crisis that sounds like something out of the Book of Exodus: A plague of locusts is spreading across the region, threatening the food supply of tens of millions. City-sized swarms of the dreaded pests are wreaking havoc as […]

Half-a-million insect species face extinction – Scientists warn humanity about worldwide insect decline – “The current insect extinction crisis is deeply worrying. Yet, what we know is only the tip of the iceberg.”

By Marlowe Hood 10 February 2020 (PhysOrg) – Half of the one million animal and plant species on Earth facing extinction are insects, and their disappearance could be catastrophic for humankind, scientists have said in a “warning to humanity”. “The current insect extinction crisis is deeply worrying,” said Pedro Cardoso, a biologist at the Finnish […]
