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 […]

Change in primary energy by fuel, 2007-2021. Primary energy in 2021 grew by its largest amount in history, with emerging economies accounting for most of the increase. Primary energy grew by 31 exajoules (EJ) in 2021, the largest increase in history and more than reversing the sharp decline seen in 2020. Primary energy in 2021 was 8 EJ above 2019 levels. The increase in primary energy in 2021 was driven by emerging economies, which increased by 13 EJ, with China expanding by 10 EJ. Taking 2020 and 2021 together, primary energy consumption in emerging economies increased by 15 EJ, largely reflecting growth in China (13 EJ). In contrast, energy demand in developed economies in 2021 was 7 EJ below 2019 levels. The increase in primary energy between 2019 and 2021 was entirely driven by renewable energy sources. The level of fossil fuel energy consumption was unchanged between 2019 and 2021, with lower oil demand (-8 EJ) offset by higher natural gas (5 EJ) and coal (3 EJ) consumption. Graphic: BP

BP Statistical Review of World Energy 2022: Carbon emissions rebound after pandemic dip – Coal prices surge – “The world remains on an unsustainable path”

By Spencer Dale 28 June 2022 (BP) – The challenges and uncertainties facing the global energy system are at their greatest for almost 50 years, at the time of the last great energy shocks of the 1970s. Most immediate is the impact of the terrible events taking place in Ukraine, with its tragic toll on […]

Total annual global cement emissions, 1990-2021. Making cement emits carbon dioxide two ways, one from the chemical process and the other from heating the chemicals. Global carbon dioxide emissions from cement making have tripled in the last 30 years and doubled in the last 20 years. Data: Robbie Andrew / CICERO Center for International Climate Research.

Carbon dioxide emissions from cement production double in 20 years – “Each person on the planet is consuming on average more than a kilogram of cement per day”

By Seth Borenstein 22 June 2022 (AP) – Heat trapping carbon dioxide emissions from making cement, a less talked about but major source of carbon pollution, have doubled in the last 20 years, new global data shows. In 2021, worldwide emissions from making cement for buildings, roads and other infrastructure hit nearly 2.9 billion tons […]

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 daily atmospheric CO2, 2012-2022. The figure shows daily averaged CO2 from four GML Atmospheric Baseline observatories; Barrow, Alaska (in blue), Mauna Loa, Hawaii (in red), American Samoa (in green), and South Pole, Antarctica (in yellow). The thick black lines represent the average of the smoothed seasonal curves and the smoothed, de-seasonalized curves for each of the records. These lines are a very good estimate of the global average levels of CO2. Data for 2022 are through 7 May 2022. Graphic: NOAA

Earth’s atmospheric CO2 hits highest recorded level in human history – Unprecedented level comes as greenhouse gas emissions continue around the world

By Ethan Freedman 6 May 2022 NEW YORK (The Independent) – Monthly average carbon dioxide (CO2) levels have reached above 420 parts per million (ppm) for the first time on record. The new data, from Hawaii’s Mauna Loa Observatory, were released by the National Oceanic and Atmospheric Administration (NOAA). Atmospheric CO2, driven higher in large part […]

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 […]

Russia’s war on Ukraine threatens climate goals, warns UN chief – “This is madness. Addiction to fossil fuels is mutually assured destruction.”

By Fiona Harvey 21 March 2022 (The Guardian) – The war in Ukraine risks putting global targets on the climate out of reach, the UN secretary general has warned, if countries respond to Russia’s aggression by increasing their use of fossil fuels. António Guterres said the aim of limiting global temperatures to 1.5C above pre-industrial levels, […]
