NASA announces July 2023 was hottest month on record – “The science is clear this isn’t normal”

By Sheri Walsh 14 August 2023 (UPI) – July 2023 was the hottest month on record in 143 years, as Americans felt “the effects of the climate crisis,” scientists at NASA’s Goddard Institute for Space Studies in New York announced Monday. According to NASA, July 2023 was on average 0.43 degrees Fahrenheit warmer than any […]

Satellite view of an algae bloom in the waters north of the Scandinavian and Kola peninsulas, 3 August 2023. The image was acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite. One group of researchers observed large shifts in the location of summer coccolithophore blooms to the northeast between 2002 and 2018. They also identified an increasing presence of Phaeocystis pouchetii, a type of phytoplankton normally found in warmer waters that can form gelatinous colonies millimeters in diameter. The effect that such changes might have on the ecosystem is a topic of ongoing research. Data: MODIS data from NASA EOSDIS LANCE and GIBS/Worldview. Photo: Michala Garrison / NASA Earth Observatory

The ocean’s color is changing as a consequence of global warming – Color changes reflect significant shifts in essential marine ecosystems – “To actually see it happening for real is not surprising, but frightening”

By Jennifer Chu 12 July 2023 (MIT News Office) – The ocean’s color has changed significantly over the last 20 years, and the global trend is likely a consequence of human-induced climate change, report scientists at MIT, the National Oceanography Center in the U.K., and elsewhere.   In a study appearing today in Nature, the team writes […]

Striking satellite photos show the dramatic scale of California’s 2023 snowpack – “This melt really is still just getting started”

By Terry Castleman 10 May 2023 (Los Angeles Times) – After a series of atmospheric rivers and cold weather hit California, this year’s snowpack was one of the biggest in history. “This year’s result will go down as one of the largest snowpack years on record in California,” Sean de Guzman, manager of the Department of Water Resources’ snow surveys, said […]

Tulare Lake flooding due to snowpack melt seen from space – “The state has both too much water and not enough”

By Jess Thomson 5 May 2023 (Newsweek) – The long-dried basin of Lake Tulare in California has rapidly refilled in the wake of intense rainfall and snowmelt. The speed and scale of the southern San Joaquin Valley lake’s return can be seen in images taken from space by the Operational Land Imager (OLI) on NASA‘s Landsat […]

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 […]

Gas flaring soars in Mexico, derailing its climate change pledges as it seeks to boost oil output – “It’s like hell”

By Stefanie Eschenbacher 23 February 2022 (Reuters) – It never gets completely dark in Colonia El Carmen, home to Mexico’s largest natural gas processing center, in the poor southern state of Chiapas. After sunset, a red glare emanates from flares dotted around the Cactus gas processing center, run by state oil company Petroleos Mexicanos (Pemex). […]

U.S. coastline to see up to a foot of sea level rise by 2050 – Report projects a century of sea level rise in 30 years – “These numbers mean a change from a single flooding event every 2-5 years to multiple events each year”

15 February 2022 (NOAA) – The United States is expected to experience as much sea level rise by the year 2050 as it witnessed in the previous hundred years. That’s according to a NOAA-led report updating sea level rise decision-support information for the U.S. released today in partnership with half a dozen other federal agencies. […]

Video: Larger-than-average ozone hole over Antarctica in 2021 – Ozone layer recovery slower than anticipated, will be no earlier than 2070

By Elizabeth Howell 5 November 2021 (Space.com) – A new NASA video highlights the giant ozone hole that opened over Antarctica this year. A cold Southern Hemisphere winter, and possible effects of global warming, have caused the hole to grow to its 13th-largest extent since 1979. The ozone depletion you see in the NASA video is monitored by three […]

Black carbon mass density over North America from GEOS-5, 21 July 2021. Smoke from wildfires in the U.S. West poured into the eastern U.S. on 20-21 July 2021. In New York City, levels of fine particulate pollution rose above 170 on the air quality index, a level considered harmful even for healthy people.

Skies turn hazy from Pittsburgh to Washington to Boston, as smoke from fires in Canada pour into the U.S. Northeast

By Adam Voiland 23 July 2021 (NASA) – While plumes of wildfire smoke from western North America have passed over the northeastern U.S. and Canada multiple times each summer in recent years, they often go unnoticed. That is because smoke that spreads far from its source typically moves at a fairly high altitude—between 5 and 10 kilometers—as […]

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 […]
