May 2020 was hottest May on record – “The really large anomalies started during January, and since then this signal has been quite persistent”

By Kelly Macnamara and Marlowe Hood 5 June 2020 PARIS (AFP) – Temperatures soared 10 degrees Celsius above average last month in Siberia, home to much of Earth’s permafrost, as the world experienced its warmest May on record, the European Union’s climate monitoring network said Friday. Large swathes of Siberia have been unusually warm for […]

Millennials are the unluckiest generation in U.S. history – “It’s not just that it’s a bad recession, and that it’s hitting young people more, but that it’s hitting people who have already been hit”

By Andrew Van Dam 27 March 2020 (The Washington Post) – After accounting for the present crisis, the average millennial has experienced slower economic growth since entering the workforce than any other generation in U.S. history. Millennials will bear these economic scars over the rest of their lives, in the form of lower earnings, lower […]

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 […]

Dangerous humid heat extremes occurring decades earlier than expected – “We are already locked in to large increases in the frequency and intensity of extreme humid heat events, and the risk is much larger than most people appreciate”

8 May 2020 (NOAA) – Oppressively hot summer days often evoke the expression, “it’s not the heat, it’s the humidity.” That sticky, tropical-like air combined with high temperatures is more than unpleasant — it makes extreme heat a greater health risk. Climate models project that combinations of heat and humidity could reach deadly thresholds for […]

Two Michigan dams breached, thousands evacuated amid “devastating” record flooding – “It’s hard to believe that we’re in the midst of a 100-year crisis – a global pandemic – and a flooding event that looks to be the worst in 500 years”

By Elisha Fieldstadt and Doha Madani21 May 2020 (NBC News) – About 11,000 people in central Michigan were told to evacuate their homes after rapidly rising water overwhelmed dams, creating what the National Weather Service called a “life-threatening situation.” Gov. Gretchen Whitmer said the destruction in Midland County caused by the failures of the Edenville […]

U.S. unemployment rate soars to 14.7 percent, the worst since the Great Depression – “This is a catastrophe. When things go over a cliff, they usually they don’t recover quickly.”

By Heather Long 8 May 2020 (The Washington Post) – The U.S. unemployment rate jumped to 14.7 percent in April, the highest level since the Great Depression, as most businesses shut down or severely curtailed operations to fight the deadly coronavirus. The jobless rate was pushed higher because 20.5 million people lost their jobs last […]

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 […]

Miami is shattering heat records during a wildly-warm start to 2020 – Most of Florida has endured record heat in the past four weeks

By Matthew Cappucci 15 April 2020 (The Washington Post) – Florida is supposed to be warm. After all, it’s, well, Florida. But temperatures in the Sunshine State have been shattering records and rivaling typical readings during the heart of summer. Miami even endured its earliest heat wave on record last week, when it hit at […]

10 years after BP spill: Oil drilled deeper; rules relaxed – “I’m concerned that in the industry, the lessons aren’t fully learned — that we’re tending to backslide”
