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 […]

Satellite view of the turf farm site in the Qatar desert, August 2021. World Cup organisers have created a large-scale tree and turf nursery, the largest turf farm in the world, according to the organisers, in the middle of the desert. It covers an area of 425,000 m2. While irrigation uses treated sewage water, the claim that this will absorb CO2 emissions from the atmosphere and contribute to reducing the impact of the event is not credible as this carbon storage is unlikely to be permanent in these artificial and vulnerable green spaces, while carbon dioxide stays in the atmosphere for centuries to millenia. Lusail stadium is the largest of the FWC stadiums, with a capacity of 80,000 seats. It is represented here to show the scale of the turf farm. Lusail stadium is not located next to the turf farm.

World Cup 2022: The “mirage” of carbon offsetting

By Stéphane Mandard 19 November 2022 (Le Monde) – Organizers will have to buy 3.6 million carbon credits to compensate for emissions, according to FIFA. Carbon Market Watch says this estimate is too low – and a long way off. FIFA claims that the World Cup in Qatar will be the first to be “carbon […]

Projections of GHG emissions under different scenarios to 2050 and indications of emissions gap and global warming implications over this century (medians only). Looking beyond 2030, this figure projects global GHG emissions out to 2050 under different scenarios and indicates the associated global warming implications over this century. The figure illustrates the substantial increase in the emissions gap for 2050 if climate efforts implied by current policies and NDC scenarios are continued without further strengthening. Implementation of net-zero targets by around mid-century would significantly reduce these gaps, but even then, gaps with the 1.5°C scenarios would remain. Graphic: UNEP

UN: Inadequate progress on climate action makes rapid transformation of societies only option – “It is a tall, and some would say impossible, order to reform the global economy and almost halve greenhouse gas emissions by 2030, but we must try”

NAIROBI, 27 October 2022 – As intensifying climate impacts across the globe hammer home the message that greenhouse gas emissions must fall rapidly, a new UN Environment Programme (UNEP) report finds that the international community is still falling far short of the Paris goals, with no credible pathway to 1.5°C in place. However, the Emissions Gap Report […]

Climate change has come for the world’s largest greenhouse gas emitter – “There is nothing in world climatic history which is even minimally comparable to what is happening in China”

By Muizz Akhtar 29 September 2022 (Vox) – China just finished one of its most disastrous summers on record, with record-breaking heat, drought, and wildfires leading to water shortages even into the fall. More than 900 million people — or about 64 percent of China’s population — faced brutal heat waves alone, highlighting how much further the nation has to […]

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 […]

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, […]

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 […]

Global greenhouse gas reduction in 2020 from pandemic and global recession “was 10 times greater than the impact on emissions from the 2008 global financial crisis”

By Alfredo Rivera, Shweta Movalia, Hannah Pitt, and Kate Larsen 23 December 2021 (Rhodium Group) – Understanding annual trends in greenhouse gas (GHG) emissions is a critical input for decision-makers in their efforts to reach net-zero emissions, whether is at the national, state, city, or corporate levels. Tracking emissions of the 190+ Parties to the […]

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 […]
