The Ozone Mapping and Profiler Suite (OMPS) and the Visible Infrared Imaging Radiometer Suite (VIIRS) on the NOAA-NASA Suomi NPP satellite captured this extremely think blanket of smoke along the West Coast on 9 September 2020. OMPS measured smoke clouds over the western U.S. with higher aerosol index values than anything Colin Seftor, an atmospheric scientist at NASA’s Goddard Space Flight Center, says he has ever seen with the instrument.

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 […]

On 9 September 2020, the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this natural-color image of thick smoke streaming from a line of intense fires in Oregon and California. Many communities in the region are facing extremely poor and sometimes hazardous air quality. Data: NASA EOSDIS/LANCE and GIBS/Worldview. Photo: Lauren Dauphin / NASA

Autumn could deliver the worst of California’s 2020 fire season – A scorching Labor Day weekend brought an all-time record heat and unprecedented fire spread, but fire risks climb in the fall

By Bob Henson 8 September 2020 (Yale Climate Connections) – Temperatures reached ghastly levels in southern California and wildfire carved a path close to two of the state’s iconic national parks as a historic heat dome gripped the western United States during the traditional end-of-summer Labor Day weekend. The heat had eased somewhat by Tuesday, […]

Total summer (yellow bars; 1 April – 1 October), winter (gray; 1 October – 1 April), and annual (orange bars; 1 October – 1 October) honey bee colony loss rates in the United States across years of the Bee Informed Partnership’s national honey bee colony loss survey, 2007/2008-2019/2020.

Annual U.S. honey bee survey shows Summer 2019 marked highest colony losses ever recorded

22 June 2020 (The Bee Informed Partnership) – The western honey bee, the species used across the country to support food production, to provide a natural sweetener, and to quite simply contribute to our leisure and free time, is among the most important of pollinators. To mark Pollinator Week, the Bee Informed Partnership (BIP) recently […]

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.

NOAA Annual Greenhouse Gas Index reached another record high in 2019 – Total direct radiative forcing has increased 45 percent since 1990

14 May 2020 (NOAA) – […] The NOAA monitoring program provides high-precision measurements of the global abundance and distribution of long-lived greenhouse gases that are used to calculate changes in radiative climate forcing. Air samples are collected through the NOAA/GML global air sampling network, including a cooperative program for the carbon gases which provides samples […]

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 […]

Before-and-after photos show dramatic decline in air pollution around the world during coronavirus lockdown

By Sophie Lewis 22 April 2020 (CBS News) – As humans continue to stay indoors under lockdown due to the coronavirus pandemic, the Earth is slowly healing. Wild animals have taken to roaming the streets, clear waters have returned to the Venice canals and the world is literally shaking less. With billions of people quarantined and businesses closed, travel has all but […]

Arctic ozone depletion tracks at record levels in Spring 2020

9 April 2020 (WMO) – Depletion of the ozone layer, the shield that protects life on Earth from harmful levels of ultraviolet radiation, is at an unprecedented level over large parts of the Arctic this spring . This phenomenon is caused by the continuing presence of ozone-depleting substances in the atmosphere and a very […]

Ukraine in flames: Chernobyl wildfire highlights a dangerous tradition – “We can’t afford to preserve such extreme traditions anymore”

By Veronika Melkozerova 18 April 2020 KYIV, Ukraine (NBC News) – Wind-whipped wildfires have in recent days raged perilously close to the exclusion zone at Chernobyl, the site of what is considered to have been the world’s worst nuclear disaster. But these fires were no accident — they were set by villagers who were clearing their land for […]
