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 […]

WMO annual report highlights continuous advance of climate change – “While greenhouse gas emissions continue to rise and the climate continues to change, populations worldwide continue to be gravely impacted by extreme weather and climate events”

Geneva, 21 April 2023 (WMO) – From mountain peaks to ocean depths, climate change continued its advance in 2022, according to the annual report from the World Meteorological Organization (WMO). Droughts, floods, and heatwaves affected communities on every continent and cost many billions of dollars. Antarctic sea ice fell to its lowest extent on record […]

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 […]

Termites in Australia are hungry and marching as the climate heats up – “It’s a matter of when, not if. They’re going to get here, and when they get here, they’re going to cause a lot of problems.”

By Frances Vinall 1 January 2023 TENNANT CREEK, Australia (The Washington Post) – In a forgotten restaurant behind a gas station in this country’s red center, only metal and plastic parts remain unscathed. Chris Cook grabs at a timber door frame, which crumples like paper in his hand. “This has all just collapsed,” says Cook, […]

Greenhouse gas levels hit new highs in 2022 – Biggest increase in methane since measurements began – “The continuing rise in concentrations of the main heat-trapping gases, including the record acceleration in methane levels, shows that we are heading in the wrong direction”

GENEVA / NEW YORK, 26 October 2022 (WMO) – In yet another ominous climate change warning, atmospheric levels of the three main greenhouse gases – carbon dioxide, methane and nitrous oxide all reached new record highs in 2021, according to a new report from the World Meteorological Organization (WMO). WMO’s Greenhouse Gas Bulletin reported the biggest […]

Components of the global carbon budget and their uncertainties, 1960-2021 and projected to 2022. Components are presented individually for (a) fossil CO2 and cement carbonation emissions (EFOS), (b) growth rate in atmospheric CO2 concentration (GATM), (c) emissions from land-use change (ELUC), (d) the land CO2 sink (SLAND), (e) the ocean CO2 sink (SOCEAN), and (f) the budget imbalance that is not accounted for by the other terms. Positive values of SLAND and SOCEAN represent a flux from the atmosphere to land or the ocean. All data are in GtC yr−1 with the uncertainty bounds representing ±1 standard deviation in shaded colour. Data sources are as in Fig. 3. The red dots indicate our projections for the year 2022, and the red error bars the uncertainty in the projections. Graphic: Friedlingstein, et al., 2022 / Earth System Science Data

Global Carbon Budget 2022: Global carbon emissions in 2022 remain at record levels – No sign of decrease in global CO2 emissions – “This year we see yet another rise in global fossil CO2 emissions, when we need a rapid decline”

11 November 2022 (Global Carbon Project) – Global carbon emissions in 2022 remain at record levels – with no sign of the decrease that is urgently needed to limit warming to 1.5°C, according to the Global Carbon Project science team (Global Carbon Budget 2022). If current emissions levels persist, there is now a 50% chance […]

Nord Stream rupture may mark biggest single methane release ever recorded, U.N. says – “This is the most wasteful way to generate emissions”

By Richard Valdmanis; editing by Frances Kerry and Howard Goller 30 September 2022 (Reuters) – The ruptures on the Nord Stream natural gas pipeline system under the Baltic Sea have led to what is likely the biggest single release of climate-damaging methane ever recorded, the United Nations Environment Programme said on Friday. A huge plume […]

Study finds super-emitters responsible for nearly 40 percent of methane emissions in five U.S. basins – “These findings drive home the need for swift action to advance strong methane rules in the U.S.”

PASADENA, 13 September 2022 (JPL) – A study released today by Carbon Mapper, University of Arizona, NASA’s Jet Propulsion Laboratory (JPL), Arizona State University, and Environmental Defense Fund (EDF) shows that strong methane point sources contribute an average of 40% of total emissions across multiple basins in the U.S., revealing that a small number of […]
