Dead oysters in a commercial oyster bed that were killed by the record heat wave in British Columbia in 2021. When Judy Hicks headed to the beach on 2 July 2021, she discovered that many of her oysters had cracked-open shells, indicating they’d died during the heat wave. From 25 June 2021 to 1 July 2021, during B.C.’s unprecedented “heat dome” that caused hundreds of human fatalities, record-breaking temperatures are estimated to have killed more than one billion sea animals.

BC’s shellfish farmers struggle after record heatwave decimates oysters – “I have been in this industry for 36 years, and I have never seen a mortality rate like this”

By Vaishnavi Dandekar 5 Aug 2021 (The Tyee) – Judy Hicks, a commercial shellfish grower in Okeover Inlet, B.C., started her day early on July 2. Weather forecasts had predicted that temperatures would reach the mid-20s that day — after hitting the mid-to-high 30s earlier that week — and Hicks wanted to avoid the heat. […]

Black carbon mass density over North America from GEOS-5, 21 July 2021. Smoke from wildfires in the U.S. West poured into the eastern U.S. on 20-21 July 2021. In New York City, levels of fine particulate pollution rose above 170 on the air quality index, a level considered harmful even for healthy people.

Skies turn hazy from Pittsburgh to Washington to Boston, as smoke from fires in Canada pour into the U.S. Northeast

By Adam Voiland 23 July 2021 (NASA) – While plumes of wildfire smoke from western North America have passed over the northeastern U.S. and Canada multiple times each summer in recent years, they often go unnoticed. That is because smoke that spreads far from its source typically moves at a fairly high altitude—between 5 and 10 kilometers—as […]

Total greenhouse gas emissions from China and OECD nations, 1990-2019. In 2019, China’s GHG emissions passed the 14 gigaton threshold for the first time, reaching 14,093 million metric tons of CO2 equivalent (MMt CO2e). This represents a more than tripling of 1990 levels, and a 25 percent increase over the past decade. As a result, China’s share of the 2019 global emissions total of 52 gigatons rose to 27 percent.

China’s greenhouse gas emissions exceeded the developed world for the first time in 2019

By Kate Larsen, Hannah Pitt, Mikhail Grant, and Trevor Houser 6 May 2021 (Rhodium Group) – Each year Rhodium Group provides the most up-to-date global and country-level greenhouse gas (GHG) emissions estimates through the ClimateDeck (a partnership with Breakthrough Energy). In addition to our preliminary US and China GHG estimates for 2020, Rhodium provides annual estimates of economy-wide emissions—including all […]

Anomalies of 2021 highest daily maximum temperature (TXx) in Western North America, assuming the rest of the summer is cooler than the June 2021 heatwave. Note that some stations do not have data up to the peak of the heatwave yet and hence underestimate the event. The black box indicates the study region. Data: GHCN-D downloaded on 4 July 2021.
