Flood gates on Trump’s border wall blown open by monsoon rains near San Bernardino Ranch in Arizona on 16 July 2021. Much of the West is suffering through a deep megadrought, but the monsoon rains that have swept across parts of the Southwest this summer have doused the southern half of Arizona with record-setting rains. Douglas has seen nearly double its average monsoon season rainfall so far, including a blast that came through on Monday and unleashed flooding on the Arizona-Sonora border. The National Weather Service data shows 2.15 inches (5.5 centimeters) of rain fell, which in turn funneled into washes and drove flooding. Photo: Fernando Sobrazo

Trump’s border wall torn apart by Arizona monsoon rains – “It’s not often that an ecologist can actually put a time stamp on the day that the evolutionary history of an area was sealed off”

By Brian Kahn 22 August 2021 (Gizmodo) – It turns out ignoring bedrock environmental laws may not have been the best choice for a multibillion-dollar construction project. Photos show former President Donald Trump’s border wall in deep disrepair after summer monsoon rains literally blew floodgates off their hinges. The damage took place near San Bernardino Ranch, a […]

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. […]

Map showing trends of early-warning indicators of Atlantic Meridional Overturning Circulation (AMOC) collapse. a, Linear trends of the corrected restoring rate λ estimated from the HadISST dataset assuming autocorrelated noise. b, Same as (a) but for the EN4 salinity dataset. c, Linear trends of the variance estimated from the HadISST dataset. d, Same as (c) but for the EN4 salinity dataset. e, Linear trends of the AC1 estimated from the HadISST dataset. f, Same as (e) but for the EN4 salinity dataset. Note the high positive values in the northern Atlantic and the subpolar gyre region in particular for λ and AC1, but also in the southern Atlantic ocean where a salinity pileup has recently been associated with an AMOC slowdown.

Gulf Stream could be veering toward irreversible decline, a new analysis warns – Atlantic current “approaching a critical threshold beyond which the circulation system could collapse”

By Ben Turner 6 August 2021 (LiveScience) – One of the most crucial ocean current systems for regulating the Northern Hemisphere’s climate could be on the verge of total collapse due to climate change, a new study has revealed. The Atlantic Meridional Overturning Circulation (AMOC), which includes the Gulf Stream and is responsible for moderating […]

Thousands of dead mussels are seen at the waterline in British Columbia, killed by the deadly heatwave 2021. More than one billion marine animals along Canada’s Pacific coast are likely to have died from the record heatwave, experts warn, highlighting the vulnerability of ecosystems unaccustomed to extreme temperatures.

Heat dome probably killed 1 billion marine animals on Canada coast in 2021 – “A lot of species are not going to be able to keep up with the pace of change”

By Leyland Cecco 8 July 2021 TORONTO (The Guardian) – More than one billion marine animals along Canada’s Pacific coast are likely to have died from last week’s record heatwave, experts warn, highlighting the vulnerability of ecosystems unaccustomed to extreme temperatures. The “heat dome” that settled over western Canada and the north-western US for five days pushed temperatures […]

Seasonal honey bee colony loss rates in the United States, 2008-2021. Annual loss estimates (from one 1 April to the next 1 April) combine winter (1 October – 1 April) and summer (1 April – 1 October) losses. The loss rate was calculated as the total number of colonies lost divided by the number of colonies “at risk” during the season. Colonies at risk were composed of viable colonies and new colonies made or acquired, while excluding colonies sold or parted with. Graphic: Bee Informed Partnership

U.S. honey bee colonies hit by second-highest annual loss on record in 2021

By Nathalie Steinhauer, Dan Aurell, Selina Bruckner, Mikayla Wilson, Karen Rennich, Dennis vanEngelsdorp, and Geoffrey Williams 23 June 2021 (Bee Informed Partnership) – The Bee Informed Partnership (http://beeinformed.org) is a non-profit organization that works alongside beekeepers to improve honey bee colony health and survivorship across the United States. One of the organization’s longest running programs, […]

Sea level rise is killing trees along the Atlantic coast, creating “ghost forests” that are visible from space

By Emily Ury 6 April 2021 (The Conversation) – Trekking out to my research sites near North Carolina’s Alligator River National Wildlife Refuge, I slog through knee-deep water on a section of trail that is completely submerged. Permanent flooding has become commonplace on this low-lying peninsula, nestled behind North Carolina’s Outer Banks. The trees growing in […]

Criminal mining groups are encroaching on the indigenous territory that straddles Brazil and Venezuela, polluting rivers, bringing diseases […]

Western Monarch butterfly abundance at 149 overwintering sites in California, 2017-2021. These critically low numbers follow two years with fewer than 30,000 butterflies—the previous record lows, indicating that the western monarch butterfly migration is nearing collapse. Sites were visited during both the Thanksgiving and New Year’s Counts during the 2020–2021 count season. Graphic: Xerces Society

Western Monarch butterfly population closer to extinction – No Endangered Species Act protection in sight – “In only a few decades, a migration of millions has been reduced to less than two thousand butterflies”

PORTLAND, Oregon, 19 January 2021 – The Xerces Society today announced that only 1,914 monarch butterflies were recorded overwintering on the California coast this year. This critically low number follows two years with fewer than 30,000 butterflies—the previous record lows—indicating that the western monarch butterfly migration is nearing collapse.
