Wildfires in Canada’s Northwest Territories have released 97 megatons of carbon, 277 times what its people emit – Emissions from wildfires across Canada in 2023 vastly exceed the 2014 record

By Liny Lamberink 28 August 2023 (CBC News) – Wildfires in the N.W.T have emitted 97 megatonnes of carbon into the air so far this year — 277 times more than what was caused by humans in the territory back in 2021. Mark Parrington, a senior scientist working at the European Union’s Copernicus Atmosphere Monitoring Service (CAMS), […]

Changes of sea surface temperature (SST) gradient anomalies and the spatial distribution of SST to a changing CO2 pathway. (A) Time evolution of latitudinal gradient of sea surface temperature anomaly (unit: °C) in the SH (pink) from its PD value. (B) Same as (A) but for the NH (black), the North Pacific (NP; 120°E to 90°W, green dotted line), and the North Atlantic (NA; 70°W to 0°E, orange dashed line) sectors with the Atlantic meridional overturning circulation (AMOC) strength anomaly from its PD value (skyblue; unit: Sv). The SST gradient is determined by the SST differences from the tropics (0° to 15°) to the midlatitudes (45° to 60°) in each hemisphere. The AMOC strength is defined by averaging annual-mean Atlantic meridional ocean stream function within the latitudinal band from 35°N to 45°N at a depth of 1000 m. Note that the weakening of AMOC is upwards in the right axis in (B). All values are based on the ensemble mean of 28 members (subjected to an 11-year running mean), with their 1 SD ranges across the ensemble members marked with shading. (C to E) SST changes (unit: °C) for peak (2121–2160) minus early RU (2001–2040) periods, late RD (2241–2280) minus peak periods, and late RD minus early RU periods, respectively. Climatological SST in the PD climate (unit: °C) is contoured in (C) to (E). The hatched regions in (C) to (E) indicate where temperature changes are statistically insignificant at the 95% confidence level. The SH, NP, and NA sectors for the SST gradient in (A) and (B) are denoted by colored boxes in (C) to (E). Graphic: Kim, et al., 2023 / Science Advances

Removing carbon from Earth’s atmosphere may not “fix” climate change – Changes to atmospheric circulation caused by global warming may persist for centuries after CO2 concentrations decrease – “We cannot control nature. We cannot reverse the consequences that easily. We cannot fix nature.”

By Tereza Pultarova 28 July 2023 (Space.com) – Removing carbon from Earth’s atmosphere may not reverse devastating changes to weather patterns in vulnerable areas, a new study suggests. In the study, Korean researchers simulated how removing large quantities of the greenhouse gas carbon dioxide from the air might affect the progress of local climate changes […]

Primary energy global consumption (left) and share of global primary energy by source (right), 2000-2022. Primary energy demand growth slowed in 2022, increasing by 1.1 percent, compared to 5.5 percent in 2021, and taking it to around 3 percent above the 2019 pre-COVID level. Consumption increased in all regions apart from Europe (-3.8 percent) and CIS (-5.8 percent). Renewables’ (excluding hydro) share of primary energy consumption reached 7.5 percent, an increase of nearly 1 percent over the previous year. Fossil fuel consumption as a percentage of primary energy remained steady at 82 percent. Graphic: Energy Institute

China is pumping out carbon emissions in 2023 as if COVID never happened – “China’s new path seems to be less sustainable than before”

By David Stern and Khalid Ahmed 9 July 2023 (The Conversation) – Carbon emissions from China are growing faster now than before COVID-19 struck, data show, dashing hopes the pandemic may have put the world’s most polluting nation on a new emissions trajectory. We compared emissions in China over the first four months of 2019 […]

Illustration showing that Chevron omits more than 90 percent of its emissions in its “net zero” “aspiration”. Though Chevron is quick to proffer its “net zero” commitment as proof of its commitment to address climate change, its “net zero” pledge is 1) only an “aspiration”, as carefully stated on its website; and 2) only applies to its Scope 1 emissions (that result from operating the facilities/equipment/vehicles/buildings that Chevron owns) and Scope 2 emissions (produced from the energy Chevron uses), not its Scope 3 emissions (caused by the end-use of Chevron’s products – sold oil and gas).

“Worthless”: Chevron’s carbon offsets are mostly junk and some may harm – “It’s clear from this report and other research that net zero as a framework opens the door for claims of climate action while continuing with business as usual”

By Nina Lakhani 24 May 2023 NEW YORK (The Guardian) – A new investigation into Chevron’s climate pledge has found the fossil-fuel company relies on “junk” carbon offsets and “unviable” technologies, which do little to offset its vast greenhouse gas emissions and, in some cases, may actually be causing communities harm. Chevron, which reported $35.5bn […]

NOAA index tracks how greenhouse gas pollution amplified global warming in 2022 – Methane and nitrous oxide rise near record levels – “Alternative energy sources to replace fossil fuels exist, but cutting emissions associated with producing food is perhaps an even more difficult task”

23 May 2023 (NOAA) – Greenhouse gas pollution from human activity trapped 49 percent more heat in the atmosphere during 2022 than those same gases did in 1990, according to an annual NOAA report. NOAA’s Annual Greenhouse Gas Index, known as the AGGI, tracks increases in the warming influence of heat-trapping gases generated by human activity, […]

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
