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 […]

WMO: 2020 on track to be one of three warmest years on record – More than 80 percent of the global ocean experienced a marine heatwave in 2020

GENEVA, 2 December 2020 (WMO) – Climate change continued its relentless march in 2020, which is on track to be one of the three warmest years on record. 2011-2020 will be the warmest decade on record, with the warmest six years all being since 2015, according to the World Meteorological Organization. Ocean heat is at […]

California’s wildfire smoke plumes are unlike anything previously seen – California fire carbon emissions in 2020 exceed previous record by nearly 2 times

By Matthew Cappucci 12 September 2020 (The Washington Post) – More than 3.1 million acres have burned in California this year, part of a record fire season that still has four months to go. A suffocating cloud of smoke has veiled the West Coast for days, extending more than a thousand miles above the Pacific. And the […]

World consumption of primary energy in exajoules, 1994-2019. Primary energy consumption rose by 1.3 percent in 2019, less than half its rate in 2018 (2.8 percent). Growth was driven by renewables (3.2 EJ) and natural gas (2.8 EJ), which together contributed three quarters of the increase. All fuels grew at a slower rate than their 10-year averages, apart from nuclear, with coal consumption falling for the fourth time in six years (-0.9 EJ). By region, consumption fell in North America, Europe and CIS, and growth was below average in South and Central America. In the other regions, growth was roughly in line with historical averages. China was the biggest individual driver of primary energy growth, accounting for more than three quarters of net global growth. Oil continues to hold the largest share of the energy mix (33.1 percent). Coal is the second largest fuel but lost share in 2019 to account for 27.0 percent, its lowest level since 2003. The share of both natural gas and renewables rose to record highs of 24.2 percent and 5.0 percent respectively. Renewables has now overtaken nuclear, which makes up only 4.3 percent of the energy mix. The share of hydroelectricity has been stable at around 6 percent for several years. Graphic: BP

BP Statistical Review of World Energy 2020: Carbon emissions increase for another year, coal still the single largest source of power generation

By Bernard Looney 17 June 2020 (BP) – The COVID-19 pandemic may well turn out to be the most tragic and disruptive event that many of us will ever live through. As I write this – in the middle of June – over 400 thousand people globally have lost their lives to the infection. Millions […]

Annual Greenhouse Gas Index (AGGI), 1750-2019. For 2019, the AGGI was a record high 1.45, representing an increase in total direct radiative forcing of 45% since 1990. The increase in radiative forcing from CO2 alone since 1990 was 60.6%. Pre-1978 changes in the CO2-equivalent abundance and AGGI are based on the ongoing measurements of all greenhouse gases reported here, measurements of CO2 going back to the 1950s from C.D. Keeling (Keeling et al., 1958), and atmospheric changes derived from air trapped in ice and snow above glaciers (Machida et al., 1995, Battle et al., 1996, Etheridge, et al., 1996; Butler, et al., 1999). Equivalent CO2 atmospheric amounts (in ppm) are derived with the relationship between CO2 concentrations and radiative forcing from all long-lived greenhouse gases.

COVID-19 crisis causes 17 percent drop in global carbon emissions – “The drop in emissions is substantial but illustrates the challenge of reaching our Paris climate commitments”

19 May 2020 (UEA) – The COVID-19 global lockdown has had an “extreme” effect on daily carbon emissions, but it is unlikely to last – according to a new analysis by an international team of scientists. The study published in the journal Nature Climate Change shows that daily emissions decreased by 17% – or 17 […]
