A layer of dense smoke spread through much of Alberta during the week of 14 May 2023, caused by forest fires. The smoke that enveloped Calgary briefly gave the city one of the worst air-quality ratings in the world, as the fires to the north and west led to the evacuation of roughly 29,000 people across the province.

Alberta is on fire, but discussing climate change is taboo during 2023 election – “It’s very tough to talk about oil and gas in Alberta because it’s sort of the goose that lays the golden egg”

By Ian Austen 20 May 2023 (The New York Times) – When I arrived in Alberta recently to report an upcoming political story, there was no shortage of people wanting to talk about politics and the provincial election on May 29. But, even as wildfires flared earlier than usual and raged across an unusually wide […]

Extreme heat smashes records in Asia in “one of the most brutal heat events the world has ever witnessed” – Laos, Thailand, Cambodia, and Vietnam all experience temperature spikes, in some places topping 43°C (110°F)

By Matthew Cappucci 8 May 2023 (The Washington Post) – A historic heat wave is bringing largely unprecedented temperatures to Southeast Asia, delivering a dangerous heat stress that could pose grave threats to vulnerable populations and smashing all-time records. Both Vietnam and Laos have recorded their hottest temperatures ever observed, in some places topping 110 […]

Thailand air pollution leads millions to seek medical help – “Today is so smoggy. I cough so much.”

Bangkok, 20 April 2023 (AFP) – About 2.4 million people in Thailand have sought hospital treatment for medical problems linked to air pollution since the start of the year, health officials said, as toxic smog chokes parts of the country. Bangkok and the northern city of Chiang Mai were among the most polluted cities in […]

Ocean plastic pollution reaches “unprecedented” levels – The Great Pacific Garbage Patch is now so huge and permanent that a coastal ecosystem is thriving on it – “The problem is getting bigger and bigger by the minute”

By Ivana Kottasová 18 April 2023 (CNN) – Scientists have found thriving communities of coastal creatures, including tiny crabs and anemones, living thousands of miles from their original home on plastic debris in the Great Pacific Garbage Patch – a 620,000 square mile swirl of trash in the ocean between California and Hawaii. In a new study published in the Nature […]

Video: Sargassum seaweed hits Florida Keys beaches

By Richard Burkard 17 April 2023 (Knewz) – It sounds like a B-grade movie title: The approach of the 10-million pound blob. Yet it’s real, and it’s forcing swimmers and owners of beachfront property in Florida to take action. Knewz noted in late March that a giant mass of sargassum seaweed was spotted from space. It […]

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 […]

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 […]

Gulf of Mexico oil worse for climate than thought, study – “Expanding production in shallow waters, the way it’s been done historically, would have disproportionately high climate impacts”

By Drew Costley 3 April 2023 (AP) – Offshore oil and gas operations in the Gulf of Mexico are releasing far more climate-changing methane than official estimates show, according to a new study published Monday. Using data collected from aircraft in part, climate scientists found the additional methane coming from oil and gas platforms in the Gulf […]

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 […]

Bushfires could kill almost 2500 Australians by 2030 – “This is not the first report saying this sort of thing, but each of the previous ones have to some extent been ignored by government”

By Lachlan Abbott 2 January 2023 (The Sydney Morning Herald) – Increasingly frequent and severe bushfires linked to climate change could kill nearly 2500 Australians and cost the economy billions of dollars by the end of the decade, according to new research. Modelling from Monash University’s Centre for Medicine Use and Safety has estimated 2418 […]
