Global map showing the highest marine heatwave (MHW) category experienced at each pixel in 2021 (reference period 1982–2011). Light grey indicates that no MHW occurred in a pixel over the entire year. (b) Stacked bar plot showing the percentage of the surface of the ocean experiencing an MHW on any given day of the year. (c) Stacked bar plot showing the cumulative percentage of the surface of the ocean that experienced an MHW over the year. Note: These values are based on when in the year a pixel first experienced its highest MHW category, so no pixel is counted twice. Horizontal lines in this figure show the final percentages for each category of MHW. (d) Stacked bar plot showing the cumulative number of MHW days averaged over the surface of the ocean. Note: This average is calculated by dividing the cumulative sum of MHW days per pixel weighted by the surface area of those pixels.

WMO: Four key climate change indicators broke records in 2021 – Past seven years have been the warmest seven years on record – “A dismal litany of humanity’s failure to tackle climate disruption”

GENEVA, 18 May 2022 (WMO) – Four key climate change indicators – greenhouse gas concentrations, sea level rise, ocean heat and ocean acidification – set new records in 2021. This is yet another clear sign that human activities are causing planetary scale changes on land, in the ocean, and in the atmosphere, with harmful and […]

Russia tree cover loss, 2001-2021. The rate of loss in in boreal forests reached unprecedented levels in 2021, increasing by 29 percent over 2020. An unprecedented fire season in Russia drove much of this increase. Russia experienced the worst fire season since record-keeping began in 2001, with more than 6.5 million hectares of tree cover loss in 2021. While fires are a natural part of boreal forest ecosystems, larger, more intense fires are worrying. Hotter, drier weather related to climate change has led to fire-prone conditions, drier peatlands and melted permafrost. Siberia’s vast peatland area — the largest in the world — stores massive amounts of carbon, which is released into the atmosphere when peat dries up. Melting permafrost also releases stored carbon and methane. These conditions may represent a new normal, impacting people living in Siberia and creating a feedback loop in which increasing fires and carbon emissions reinforce each other and lead to worsening conditions.

Vast forest losses in 2021 imperil global climate targets, report says – “We’re seeing fires burning more frequently, more intensively and more broadly than they ever would under normal conditions”

By Jake Spring 28 April 2022 SAO PAULO, April 28 (Reuters) – The world lost an area of forest the size of the U.S. state of Wyoming last year, as wildfires in Russia set all-time records and Brazilian deforestation of the Amazon remains high, a global forest monitoring project report said on Thursday. Global Forest Watch, which […]

U.S. solar expansion stalled by rural land-use protests – “It’s pretty obvious that, if there’s a climate urgency, we’re not behaving that way”

By Nichola Groom 7 April 2022 (Reuters) – The Solar Star project in California is among the largest solar energy facilities in the world, boasting 1.7 million panels spread over 3,000 acres north of Los Angeles. Its gargantuan scale points to an uncomfortable fact for the industry: a natural gas power plant 100 miles south […]

WMO: Antarctic heat, rain, and ice prompt concern – “This event is rewriting record books and our expectations about what is possible in Antarctica”

1 April 2022 (WMO) – Record high temperatures, rain and the collapse of an ice shelf in East Antarctica have prompted questions and concern about the possible role of climate change in the coldest and driest part of the world. Record high temperatures, rain and the collapse of an ice shelf in East Antarctica have […]

Octopuses are using human garbage as shelter, camouflage and more, study finds – “It’s becoming so common that they’re using these items to protect themselves with instead of their natural shelters, such as seashells, which are becoming scarce in the ocean”

9 March 2022 (CBC Radio) – A new study suggests it’s becoming increasingly common for octopuses to use bottles, cans and other human trash to shelter themselves, camouflage their dens and even house their young. “We believe this is because of the high abundance of these artificial items — you know, the litter item — […]

The Amazon Rainforest is approaching a tipping point beyond which it would become savannah – “When it will be observable, it would likely be too late to stop it”

By Eric Shank 14 March 2022 (Salon) – A vast expanse of unique biological diversity hangs in the balance as the “lungs of the world” approach a tipping point from which there is no recovery. The Amazon Rainforest is losing its ability to regenerate, reported a peer-reviewed study, Monday, in Nature Climate Change. For 10% of all known species on […]
