Despite pandemic shutdowns, carbon dioxide and methane surged in 2020 – Carbon dioxide levels now higher than any time in past 3.6 million years – Largest annual methane increase ever recorded

7 April 2021 (NOAA) – Levels of the two most important anthropogenic greenhouse gases, carbon dioxide and methane, continued their unrelenting rise in 2020 despite the economic slowdown caused by the coronavirus pandemic response, NOAA announced today. The global surface average for carbon dioxide (CO2), calculated from measurements collected at NOAA’s remote sampling locations, was […]

Monthly evolution of global CO2 emissions in 2020, relative to 2019. After hitting a low in April 2020, global emissions rebounded strongly and rose above 2019 levels in December. Global CO2 emissions were 2 percent, or 60 million tonnes, higher in December 2020 than they were in the same month a year earlier. Major economies led the resurgence as a pick-up in economic activity pushed energy demand higher and significant policies measures to boost clean energy were lacking. Many economies are now seeing emissions climbing above pre-crisis levels. Graphic: IEA

After steep drop in early 2020, global carbon dioxide emissions have rebounded strongly – “The rebound in global carbon emissions is a stark warning that not enough is being done to accelerate clean energy transitions worldwide”

2 March 2021 (IEA) – The Covid-19 crisis in 2020 triggered the largest annual drop in global energy-related carbon dioxide emissions since the Second World War, according to IEA data released today, but the overall decline of about 6% masks wide variations depending on the region and the time of year. After hitting a low in […]

10,000 years of carbon dioxide. Due in large part to the burning of fossil fuels, carbon dioxide levels in the atmosphere have now risen by about 50 percent% above the preindustrial level. At recent rates of growth, we would reach double the preindustrial by around the year 2075. Graphic: Dr. Robert Rohde

Dr. Robert Rohde 17 March 2021 (Twitter) – Due in large part to the burning of fossil fuels, carbon dioxide levels in the atmosphere have now risen about 50 percent above the preindustrial level. At recent rates of growth, we would reach double the preindustrial by around 2075. Dr. Robert Rohde on Twitter

EIA energy report explores impact of COVID-19 on U.S. energy mix through 2050 – Return to 2019 levels of U.S. energy consumption to take years – Energy-related CO2 emissions fall before leveling off or rising

By Ari Kahan 3 February 2021 (EIA) – The United States will likely take years to return to 2019 levels of energy consumption and carbon dioxide emissions following the impact of COVID-19 on the U.S. economy and global energy sector, according to projections in the U.S. Energy Information Administration’s (EIA) Annual Energy Outlook 2021 (AEO2021).

Atmospheric carbon dioxide to pass iconic threshold in 2021 – “Emissions have now returned almost to pre-pandemic levels … The human-caused build-up of CO2 in the atmosphere is accelerating”

By Grahame Madge 8 January 2021 (Met Office) – In 2021, carbon dioxide in the atmosphere will reach levels 50% higher than before the industrial revolution, due to human-caused emissions, says a Met Office forecast. The Met Office predicts that annual average CO2 concentration at Mauna Loa Observatory, Hawaii, will be 2.29 ± 0.55 parts per million (ppm) […]

China rations electricity for millions – “The whole city was dark”

By Vivian Wang 21 December 2020 (The New York Times) – In the city of Yiwu in eastern China, the authorities turned off streetlights for several days and ordered factories to open only part-time. In coastal Wenzhou, the government ordered some companies not to heat their offices unless temperatures are close to freezing. In southern […]

The global COVID-19 lockdowns caused fossil carbon dioxide emissions to decline by an estimated 2.4 billion tonnes in 2020 - a record drop according to researchers at the University of East Anglia, University of Exeter and the Global Carbon Project. It means that in 2020 fossil CO2 emissions are predicted to be approximately 34 GtCO2, seven per cent lower than in 2019. Emissions from transport account for the largest share of the global decrease. Those from surface transport, such as car journeys, fell by approximately half at the peak of the COVID lockdowns. Total CO2 emissions from human activities - from fossil CO2 and land-use change - are set to be around 39 GtCO2 in 2020. Video: UEA

COVID lockdown causes record drop in carbon dioxide emissions for 2020

11 December 2020 (UEA) – The global COVID-19 lockdowns caused fossil carbon dioxide emissions to decline by an estimated 2.4 billion tonnes in 2020 – a record drop according to researchers at the University of East Anglia (UEA), University of Exeter, and the Global Carbon Project. The fall is considerably larger than previous significant decreases […]

Carbon dioxide levels continue at record levels, despite COVID-19 lockdown – “The COVID-19 pandemic is not a solution for climate change”

GENEVA, 23 November 2020 (WMO) – The industrial slowdown due to the COVID-19 pandemic has not curbed record levels of greenhouse gases which are trapping heat in the atmosphere, increasing temperatures, and driving more extreme weather, ice melt, sea-level rise, and ocean acidification, according to the World Meteorological Organization (WMO). The lockdown has cut emissions […]
