A houseboat rests in a cove at Lake Powell near Page, Arizona on 30 July 2021. In the summer of 2021, the water levels hit a historic low amid a climate change-fueled megadrought engulfing the U.S. West. Severe drought across the West drained reservoirs in 2021, slashing hydropower production and further stressing the region’s power grids. And as extreme weather becomes more common with climate change, grid operators are adapting to swings in hydropower generation. Photo: Rick Bowmer / AP Photo

Lake Powell hits historic low, raising hydropower concerns – “We clearly weren’t sufficiently prepared for the need to move this quickly”

By Sam Metz and Felicia Fonseca 16 March 2022 SALT LAKE CITY (AP) – A massive reservoir known as a boating mecca dipped below a critical threshold on Tuesday raising new concerns about a source of power that millions of people in the U.S. West rely on for electricity. Lake Powell’s fall to below 3,525 […]

Texas wildfire kills 1, as officials worry extreme drought could worsen conditions – “In the wetter parts of Texas, there will be more fuel, and things will dry out more rapidly”

By Jack Douglas and Jacob Bogage 19 March 2022 CARBON, Texas (The Washington Post) – All Raquel Robles could do was watch the video on her phone, horrified and helpless, as first smoke, then fire, moved up her driveway and then destroyed the house she and her family had lived in for 13 years. Flames […]

Pacific Northwest heatwave in 2021 was a glimpse of global warming in North America – “We’re exposed to untold damage”

By Gillian Flaccus 1 March 2022 PORTLAND, Oregon (AP) – The U.S. Pacific Northwest was in the throes of a record-shattering heat wave last summer when a woman in her 70s was wheeled into an emergency room with symptoms of a life-threatening heat stroke. Desperate to cool her, Dr. Alexander St. John grabbed a body […]

The global expansion of authoritarian rule – “The present threat to democracy is the product of 16 consecutive years of decline in global freedom”

By Sarah Repucci and Amy Slipowitz 24 February 2022 (Freedom House) – Global freedom faces a dire threat. Around the world, the enemies of liberal democracy—a form of self-government in which human rights are recognized and every individual is entitled to equal treatment under law—are accelerating their attacks. Authoritarian regimes have become more effective at […]

Onset of modern sea level rise began in 1863, international study finds – “We can be virtually certain the global rate of sea-level rise from 1940 to 2000 was faster than all previous 60-year intervals over the last 2,000 years”

18 February 2022 (Rutgers University) – An international team of scientists including Rutgers researchers has found that modern rates of sea level rise began emerging in 1863 as the Industrial Age intensified, coinciding with evidence for early ocean warming and glacier melt. The study, which used a global database of sea-level records spanning the last […]

U.S. coastline to see up to a foot of sea level rise by 2050 – Report projects a century of sea level rise in 30 years – “These numbers mean a change from a single flooding event every 2-5 years to multiple events each year”

15 February 2022 (NOAA) – The United States is expected to experience as much sea level rise by the year 2050 as it witnessed in the previous hundred years. That’s according to a NOAA-led report updating sea level rise decision-support information for the U.S. released today in partnership with half a dozen other federal agencies. […]

U.S. Drought Monitor map of the U.S. West, 10 February 2022. In February 2022, 95 percent of the Western U.S. was experiencing drought conditions. In summer 2021, according to the U.S. Bureau of Reclamation, two of the largest reservoirs in North America — Lake Mead and Lake Powell, both on the Colorado River — reached their lowest recorded levels.

Megadrought in U.S. West worsens to driest in at least 1,200 years – “We need to be preparing for conditions in the future that are far worse than this”

By Seth Borenstein 15 February 2022 (AP) – The American West’s megadrought deepened so much last year that it is now the driest in at least 1,200 years and is a worst-case climate change scenario playing out live, a new study finds. A dramatic drying in 2021 — about as dry as 2002 and one […]

Cumulative global insured losses by peril in 2021. Aggregated costs for insurers have been largely dominated by the Tropical Cyclone and Severe Weather perils this century. The two perils combined for more than $1 trillion, or 60 percent of the total cumulative industry losses, of which roughly 74 percent was incurred in the United States. The Severe Convective Storm peril has also increasingly separated itself as accounting for the highest number of billion-dollar events. Graphic: Aon

Aon: 2021 was third costliest year on record for weather and climate-related events – Germany, Belgium, Austria, Luxembourg, and China recorded the costliest insurance industry events on record

CHICAGO, 25 January 2022 (Aon) – Aon plc (NYSE: AON), a leading global professional services firm, today published its 2021 Weather, Climate and Catastrophe Insight, which evaluates the increasing frequency and severity of disruptive natural disasters and how their resulting economic losses are protected globally. This data serves as the foundation for insights that can help […]

More than 40 percent of Americans live in counties hit by climate disasters in 2021 – “More people are living in more flammable landscapes. More people are going to be interfacing with disaster.”

By Sarah Kaplan and Andrew Ba Tran 5 January 2022 (The Washington Post) – 2021 ended as it began: with disaster. Twelve months after an atmospheric river deluged California, triggering mudslides in burned landscapes and leaving a half-million people without power, a late-season wildfire destroyed hundreds of homes in the suburbs of Denver. In between, Americans suffered blistering heat […]

Alaska sets December temperature record at 67°F (19°C) – “In late December, I would not have thought such a thing possible”

By Andrew Freedman 27 December 2021 (Axios) – A weather station mounted on a tide gauge on the picturesque island of Kodiak, Alaska, recorded an air temperature of 67°F on 26 December 2021, which if verified would become the state’s record high for the month. The big picture: Such astonishingly mild conditions in America’s Arctic state come at […]
