Physiological response curves may shift as soil microbiomes respond to drought. In the short term (minutes to days), physiological acclimation may help to sustain function, such as soil carbon decomposition. Over weeks to decades, community shifts and evolution could alter response curves to maintain functioning under dry conditions. Broken lines indicate potential variation in the breadth of the shifted response curves. Graphic: Evans, et al., 2022 / Functional Ecology

Droughts destroying Earth’s biggest carbon sink on land: study – If more carbon-releasing microbes survive than carbon-sequestering microbes, we could end up with carbon-depleted soils

By Mark Waghorn 12 April 2023 (SWNS) – Droughts are destroying Earth’s biggest carbon sink on land, according to new research. Soil stores more greenhouse gas than plants and the atmosphere combined – thanks to the microbes that live in it. Moisture plays a key role in the process. Lack of rainfall is disrupting this […]

Avian flu is killing endangered California condors at alarming rate

By Dinah Voyles Pulver 12 April 2023 (USA TODAY) – The avian influenza stalking wild and domestic bird flocks across the country has killed at least six endangered California condors since March and is suspected of killing another dozen. The U.S. Fish and Wildlife Service said Wednesday it’s now attributing all condor deaths in the […]

Sargassum seaweed soils Space Coast beaches at record levels in 2023 – “This year’s Sargassum bloom will likely be the largest ever recorded, with major impacts throughout the next few months”

By Jim Waymer 12 April 2023 (Florida Today) – We’re already in the weeds. All that stringy stuff that washed up on Brevard County beaches this past week is just the beginning of what scientists predict will grow into the largest-ever bloom of Sargassum seaweed ever recorded. Sargassum, which the Caribbean Sea delivers seasonally to the Gulf Stream […]

A wet winter won’t stave off the Colorado River’s water cuts – “There are discussions going on but they’re not making much progress. The level of distrust and animosity is really remarkable.”

By Joshua Partlow 3 April 2023 GRAND JUNCTION, Colorado (The Washington Post) – The abundant snow in the Rocky Mountains this year has been a welcome relief, but is not enough to overcome two decades of drought that has pushed major reservoirs along the Colorado River down to dangerous levels, Camille Calimlim Touton, the commissioner […]

Global monthly mean atmospheric carbon dioxide, 1979-2022. The global surface average for CO2 rose by 2.13 parts per million (ppm) to 417.06 ppm, roughly the same rate observed during the last decade. Atmospheric CO2 is now 50% higher than pre-industrial levels. 2022 was the 11th consecutive year CO2 increased by more than 2 ppm, the highest sustained rate of CO2 increases in the 65 years since monitoring began. Prior to 2013, three consecutive years of CO2 growth of 2 ppm or more had never been recorded. The Global Monitoring Division of NOAA/Earth System Research Laboratory has measured carbon dioxide and other greenhouse gases for several decades at a globally distributed network of air sampling sites. This graph shows monthly mean abundance of carbon dioxide globally averaged over marine surface sites. Graphic: NOAA Global Monitoring Laboratory

Greenhouse gases continued to increase rapidly in 2022 – Carbon dioxide, methane, and nitrous oxide rise further into uncharted levels – “Greenhouse gas emissions continue to rise at an alarming pace and will persist in the atmosphere for thousands of years”

5 April 2023 (NOAA) – Levels of carbon dioxide (CO2), methane and nitrous oxide, the three greenhouse gases emitted by human activity that are the most significant contributors to climate change, continued their historically high rates of growth in the atmosphere during 2022, according to NOAA scientists. The global surface average for CO2 rose by 2.13 […]

Deforestation in the Brazilian Amazon, February 2008 - February 2023. After a drop in January 2023, deforestation in the Amazon returned to growth in February. According to Imazon data, 325 km² of forest were cleared in February 2023, equivalent to the size of Belo Horizonte. This was the biggest devastation recorded for February in 16 years, since the research institute deployed its SAD satellite imagery monitoring system. Graphic: Imazon

A long-dormant lake has reappeared in California, bringing havoc along with it – “This impending monster – a 50-foot-plus deep snowpack that we haven’t seen in 75 years – is sitting up there, and we just don’t know how fast it’s going to turn into water and come out of the mountains”

By Evan Bush 2 April 2023 (NBC News) – People have worked for a century to make California’s Tulare Basin into a food grower’s paradise. That pastoral landscape now looks more like the Pacific Ocean in many areas. Months of atmospheric river storms have pummeled the area and saturated the basin’s soil, which sits about […]

Cocaine production is at its highest level on record, UN says – Coca cultivation soared 35 per cent from 2020 to 2021, a record high and the sharpest year-to-year increase since 2016

By Natasha Turak 16 March 2023 (CNBC) – Cocaine production is at its highest level on record, with demand rebounding post-pandemic and new trafficking hubs emerging, a report from the United Nations Office on Drugs and Crime found. The U.N.’s Global Report on Cocaine 2023 says new hubs for trafficking in the multibillion-dollar industry have […]

Record-breaking algae bloom takes aim at Florida beaches – “This year could be the biggest year yet”

By Dinah Voyles Pulver 14 March 2023 (USA TODAY) – Beachgoers in Florida and the Caribbean could be greeted by heavy blankets of smelly seaweed in the weeks ahead as a 5,000-mile swath of sargassum drifts westward and piles onto white sandy beaches. Sargassum, a naturally occurring type of macroalgae, has grown at an alarming rate this winter. The […]

The Central Valley town of Planada was devastated by widespread flooding after a severe atmospheric river event moved through the area earlier in the week. The San Francisco Bay Area and much of California continued to be drenched by powerful atmospheric river events that brought high winds and flooding rains. The storms toppled trees, flooded roads, and cut power to tens of thousands. Storms lined up over the Pacific Ocean and brought more rain and wind through the end of the week.
