...In 100 days, SARS-CoV-2 has received more attention than AGW in 20 years. That's not normal or rational. That's mass psychosis, and it's dangerous.
I agree with your sentiment entirely.
Dito. Except for the "mass psychosis" - which reeks of denialist projection. Remember the "alarmist" accusation from AGW debate? Climate alarmist! Covid alarmist! ...

One thing I welcome the Corona "mass psychosis" for: It unmasks the stupid, literally.

-----------------------
As the Covid "debate" is gaining some steam here in Germany, after a demonstration of the stupid in Berlin, I did some numbers.
August 7 2020:
Germany has 9195 Covid deaths. Compared to UK deaths/population it could be 48637 more. Compared to Sweden, 37766 more.

P.S.:
Michael Mann:
"If there is a silver lining, it is that the failure of the current administration to respond meaningfully to the pandemic lays bare the deadliness of ideologically motivated science denial. This applies to the even greater crisis of human-caused climate change and the need to treat it as the emergency it is."

The “Flat Corn” Derecho of August 10, 2020
https://www.woodtv.com/weather/particularly-dangerous-situation-derecho/amp/



... Millions of acres of corn has been blown down. If that wasn’t bad enough, many grain elevators and bins were damaged or destroyed as well.

A seiche or meteotsunami occurred on Lake Michigan this evening. The water level rose 1.5 FEET at Benton Harbor:



The strong winds from a line of thunderstorms push the water toward the Michigan shore. The water level rises at a fairly rapid rate. You can get caught out on the piers and breakwaters. As the storm passes, the water sloshes back toward the Illinois and Wisconsin shore. As it does, strong currents are possible, moving from the shore to the west and out toward open water. On July 4, 2003, seven people drowned when caught in currents following a severe thunderstorm in St. Joseph Michigan.

I agree with your sentiment entirely. But we don't have data for the varying amounts of press coverage in each country, so the actual statistical analysis is missing.

Here in Korea the coverage of Covid-19 has been enormous. Mentions of AGW are close to zero.
An outlier in the news today.
Yonhap News: S. Korean central region under 49 days of rainy season, longest on record
Quote
The monsoon season, which has begun on June 24, tied the previous record of 49 days set in 2013, the Korea Meteorological Administration (KMA) said, and will continue until Aug. 16 ...
The unusually extended rainy season is caused by climate change and the resulting warmer air that holds more moisture and brings heavier rain.

I suggest another variable that could be used to judge the level of interest in each country in AGW is the Effective Carbon Rate. In the Sustainable Development Report rankings no OECD scores well on this index. Denmark does the best followed by the Netherlands and Norway. There is no correlation between the scores on Covid-19 and  Effective Carbon Rate. The United States does badly on both. South Korea and Australia are both climate change villains but have done well against Covid-19. Denmark, the Netherlands and Norway are top for Effective Carbon Rate but average on the Covid-19 ranking.
For the data see Sustainable Development Report: Effective Carbon Rate.

The survey of nearly 500 owners and operators of restaurants, bars and nightlife establishments across the city found that a growing number of businesses could not pay rent in July.

 Numbers Continue to Climb as Indoor Dining Remains on Pause

37 Percent of Businesses Paid No Rent at All

Global Lockdowns Set to Plunge 100 Million Into Extreme Poverty
https://summit.news/2020/08/10/global-lockdowns-set-to-plunge-100-million-into-extreme-poverty/
Quote
“With the virus and its restrictions, up to 100 million more people globally could fall into the bitter existence of living on just $1.90 a day, according to the World Bank. That’s “well below any reasonable conception of a life with dignity,” the United Nations special rapporteur on extreme poverty wrote this year. And it comes on top of the 736 million people already there, half of them in just five countries: Ethiopia, India, Nigeria, Congo and Bangladesh.”

The report notes that the impact of the lockdown on the poor in countries like India was “so abrupt and punishing” that their Prime Minister, Narendra Modi, begged for forgiveness.

Antarctica / Re: Ice Apocalypse - MULTIPLE METERS SEA LEVEL RISE
« Last post by AbruptSLR on August 11, 2020, 04:34:18 PM »
The linked article indicates that a CMIP6 version of HadGEM3 (the UK's most advanced model) indicates that the Arctic may become seasonally sea ice free by 2035 (see also the associated attached image w.r.t. ECS).  If so, this would greatly increase the probability of a freshwater hosing event from the Beaufort Gyre, which, could likely trigger a bipolar seesaw cascade of subsequent freshwater hosing event such as: hosing from key ASE marine glaciers triggering hosing from key GIS marine terminating glaciers, triggering key AIS marine glaciers etc.  If so this might lead to 4 to 5m of SLR circa 2100.

Title: "Past evidence supports complete loss of Arctic sea ice by 2035"

https://phys.org/news/2020-08-evidence-loss-arctic-sea-ice.html

Extract: "During spring and early summer, shallow pools of water form on the surface of Arctic sea-ice. These 'melt ponds' are important for how much sunlight is absorbed by the ice and how much is reflected back into space. The new Hadley Centre model is the UK's most advanced physical representation of the Earth's climate and a critical tool for climate research and incorporates sea-ice and melt ponds.

Using the model to look at Arctic sea ice during the last interglacial, the team concludes that the impact of intense springtime sunshine created many melt ponds, which played a crucial role in sea-ice melt. A simulation of the future using the same model indicates that the Arctic may become sea ice-free by 2035."

https://www.nature.com/articles/s41558-020-0865-2

Abstract: "The Last Interglacial (LIG), a warmer period 130,000–116,000 years before present, is a potential analogue for future climate change. Stronger LIG summertime insolation at high northern latitudes drove Arctic land summer temperatures 4–5 °C higher than in the pre-industrial era. Climate model simulations have previously failed to capture these elevated temperatures, possibly because they were unable to correctly capture LIG sea-ice changes. Here, we show that the latest version of the fully coupled UK Hadley Center climate model (HadGEM3) simulates a more accurate Arctic LIG climate, including elevated temperatures. Improved model physics, including a sophisticated sea-ice melt-pond scheme, result in a complete simulated loss of Arctic sea ice in summer during the LIG, which has yet to be simulated in past generations of models. This ice-free Arctic yields a compelling solution to the long-standing puzzle of what drove LIG Arctic warmth and supports a fast retreat of future Arctic summer sea ice."

Out of work and with families to feed, some Americans are lining up at food banks for the first time in their lives
https://www.yahoo.com/news/food-banks-increased-demand-newcomers-unemployment-expiring-090006421.html
Quote
Across the country, Americans who’ve never had to rely on food assistance before are turning to local organizations for aid. In July, the Census Bureau reported that nearly 30 million Americans said they didn’t have enough to eat in the prior week, a situation that is likely to worsen since the expanded unemployment insurance of $600 per week ended last month. Food banks across the country are bracing for both another spike in food insecurity and the fact that the effects of the pandemic are likely to last until 2021 and beyond.
