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 […]

By Rajendra Jadhav, Mayank Bhardwaj, and Nigam Prusty 15 May 2022 MUMBAI (Reuters) – India banned wheat exports on Saturday days after saying it was targeting record shipments this year, as a scorching heat wave curtailed output and domestic prices hit a record high. The government said it would still allow exports backed by already […]

Earth energy imbalance, global net flux, 2001-2021. The 12-month EEI, Mar 2021-Feb 2022, set another record. The annual Earth’s Energy Imbalance was +1.52 W/m2, the energy equivalent to 1 million Hiroshima-sized atomic bombs every day. Data: NASA CERES. Graphic: Leon Simons

New NASA data show Earth heating at unprecedented rate – “Like 800,000 nuclear power plants of 1 GW capacity heating Earth 24/7, 365 days a year”

By Leon Simons 5 May 2022 (Twitter) – NASA data shows our Earth is heating at unprecedented speed: 1.64 W/m2. CERES radiative flux data for 2021 has come available. The annual Earth’s Energy Imbalance was +1.52 W/m2, the energy equivalent to 1 million Hiroshima sized atomic bombs every day. Another 12-month EEI record (from Mar […]

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 […]

Humanity entering “spiral of self-destruction”, UN warns – “By deliberately ignoring risk and failing to integrate it in decision making, the world is effectively bankrolling its own destruction”

26 April 2022 (France 24) – Humanity is suffering from a “broken perception of risk”, spurring us into activities and behaviours that cause climate change and a surging number of disasters around the globe, the UN warned Tuesday. In a fresh report, the UN Office for Disaster Risk Reduction, or UNDRR, found that between 350 and […]

Russia tree cover loss, 2001-2021. The rate of loss in in boreal forests reached unprecedented levels in 2021, increasing by 29 percent over 2020. An unprecedented fire season in Russia drove much of this increase. Russia experienced the worst fire season since record-keeping began in 2001, with more than 6.5 million hectares of tree cover loss in 2021. While fires are a natural part of boreal forest ecosystems, larger, more intense fires are worrying. Hotter, drier weather related to climate change has led to fire-prone conditions, drier peatlands and melted permafrost. Siberia’s vast peatland area — the largest in the world — stores massive amounts of carbon, which is released into the atmosphere when peat dries up. Melting permafrost also releases stored carbon and methane. These conditions may represent a new normal, impacting people living in Siberia and creating a feedback loop in which increasing fires and carbon emissions reinforce each other and lead to worsening conditions.
