Changes in global average sea level (background map) and local sea level (dots) between 1993 and 2021. In the global ocean, sea level has risen nearly everywhere (blue). Coastal areas where sea level has fallen (brown) are places where the land is rising as it rebounds from being compressed by ice sheets and glaciers during the last ice age.

American Meteorological Society report: Record-high greenhouse gases and sea levels in 2021 – Ocean heat content highest on record

31 August 2022 (NOAA) – Greenhouse gas concentrations, global sea levels and ocean heat content reached record highs in 2021, according to the 32nd annual State of the Climate report. The international annual review of the world’s climate, led by scientists from NOAA’s National Centers for Environmental Information and published by the Bulletin of the […]

Scientists detect second “vast” methane leak at Pemex oil field in Mexico – “It’s really alarming what is happening. Pemex should be stripped of its rights to operate it.”

MEXICO CITY, 2 September 2022 (Reuters) – Satellites recorded another large methane leak at an offshore platform belonging to Mexico’s Pemex in August, according to exclusive data shared with Reuters, even as pressure mounts on the state oil company to reduce these emissions. Three satellites recorded images of methane plumes at the Ku-Maloob-Zaap oil field […]

Annual Greenhouse Gas Index (AGGI), 1700-2021. For 2021, the AGGI was a record high 1.49, representing an increase in total direct radiative forcing of 49 percent since 1990. The atmospheric abundance of CO2 has increased by an average of 1.88 ppm per year over the past 42 years (1979-2021). This increase in CO2 is accelerating — while it averaged about 1.6 ppm per year in the 1980s and 1.5 ppm per year in the 1990s, the growth rate increased to 2.4 ppm per year during the last decade (2011-2021). The annual CO2 increase from 1 January 2021 to 1 January 2022 was 2.60 ± 0.08 ppm. Graphic: Montzka, 2022 / NOAA

Greenhouse gas pollution trapped record 49 percent more heat in 2021 than in 1990 – Methane increase in 2021 largest since 1982 – “The primary gases responsible for climate change continue rising rapidly”

23 May 2022 (NOAA) – Greenhouse gas pollution caused by human activities trapped 49 percent more heat in the atmosphere in 2021 than they did in 1990, according to NOAA scientists. NOAA’s Annual Greenhouse Gas Index, known as the AGGI, tracks increases in the warming influence of human emissions of heat-trapping gases, including carbon dioxide, methane, […]

Increase in atmospheric methane set another record during 2021 – Carbon dioxide levels also record a big jump – “The evidence is consistent, alarming, and undeniable”

7 April 2022 (NOAA) – For the second year in a row, NOAA scientists observed a record annual increase in atmospheric levels of methane, a powerful, heat-trapping greenhouse gas that’s the second biggest contributor to human-caused global warming after carbon dioxide. NOAA’s preliminary analysis showed the annual increase in atmospheric methane during 2021 was 17 […]

Global net anthropogenic greenhouse gas emissions projected to 2050. Projected global GHG emissions from Nationally Determined Contribution (NDCs) announced prior to COP26 would make it likely that warming will exceed 1.5°C and also make it harder after 2030 to limit warming to below 2°C.

Amid backsliding on climate, the renewables effort now must be tripled – “A litany of broken climate promises”

By António Guterres 4 April 2022 (The Washington Post) – A report released Monday by the Intergovernmental Panel on Climate Change is a litany of broken climate promises. Together with the IPCC’s previous two reports on physical science and adaptation in the past year, it reveals the yawning gap between climate pledges and reality. And the reality is that we are […]

Gas flaring soars in Mexico, derailing its climate change pledges as it seeks to boost oil output – “It’s like hell”

By Stefanie Eschenbacher 23 February 2022 (Reuters) – It never gets completely dark in Colonia El Carmen, home to Mexico’s largest natural gas processing center, in the poor southern state of Chiapas. After sunset, a red glare emanates from flares dotted around the Cactus gas processing center, run by state oil company Petroleos Mexicanos (Pemex). […]

WMO Greenhouse Gas Bulletin 2021: Another year, another record – “CO2 in the atmosphere breached the milestone of 400 parts per million in 2015. And just five years later, it exceeded 413 ppm.”

GENEVA, 25 October 2021 (WMO) – The abundance of heat-trapping greenhouse gases in the atmosphere once again reached a new record last year, with the annual rate of increase above the 2011-2020 average. That trend has continued in 2021, according to the World Meteorological Organization (WMO) Greenhouse Gas Bulletin. Concentration of carbon dioxide (CO2), the most […]

State of the Climate in 2021: Past seven years are on track to be the seven warmest on record – “Extreme events are the new norm”

GENEVA, 31 October 2021 (WMO) – Record atmospheric greenhouse gas concentrations and associated accumulated heat have propelled the planet into uncharted territory, with far-reaching repercussions for current and future generations, according to the World Meteorological Organization (WMO). The past seven years are on track to be the seven warmest on record, according to the provisional WMO […]

Satellites discover huge, undeclared methane emissions – “These are large emissions, and we see a lot of them on the global scale, much more than we had expected”

By Tereza Pultarova 16 November 2021 (Space.com) – Huge amounts of uncounted emissions of highly warming greenhouse gas methane are being released by “super-emitters” all over the world, satellite observations reveal. Scientists have only recently worked out how to detect methane emissions from space, but what they have seen since has taken them by surprise. […]

Time series of climate-related responses to anthropogenic drivers, 1990-2020. Out of the 31 tracked planetary vital signs, 18 were at new all-time record lows or highs in 2020. Data obtained before and after the publication of Ripple and colleagues (2020) are shown in gray and red respectively. For variables with relatively high variability, local regression trend lines are shown in black. The variables were measured at various frequencies (e.g., annual, monthly, weekly). The labels on the x-axis correspond to midpoints of years. Sources and additional details about each variable are provided in the supplemental material. Graphic: Ripple, et al., 2021 / BioScience

World scientists’ warning of a climate emergency 2021 – Humans face untold suffering from “the consequences of unrelenting business as usual”

28 July 2021 (BioScience) – In 2019, Ripple and colleagues (2020) warned of untold suffering and declared a climate emergency together with more than 11,000 scientist signatories from 153 countries. They presented graphs of planetary vital signs indicating very troubling trends, along with little progress by humanity to address climate change. On the basis of […]
