Antarctica appears to have set a new high temperature record the other day at Esperanza Base, breaking the old record also set at the same location in 2015.

Yes but that is a one day event. Looking at the ice graph, Antarctica is about at normal in ice for the season.

The Arctic ice has made a nice recovery in extent this winter. It’s currently 14th lowest on record per JAXA and the overall graph and chart is the healthiest I’ve seen in recent years. Volume is still lagging but also recovering.
And here’s how it compares overall, courtesy of the Arctic sea ice forum.

That’s pretty good considering that the Arctic has still been running AN practically every day other than in summer.

Yeah the key is the cold has been in all the key areas and there haven’t been significant warm air intrusions into the fringe areas like the Bering and Chukchi Sea areas. Volume is now 5th lowest based on PIOMAS data so still a good bit of recovery needed there.
Hard to get too warm when the big PV just cranks up there all winter. Glad there's some recovery though. Going to need to build some depth or it's not gonna hang out long.

Maybe it will tame the summer heat too when the PV relaxes.

I'm really surprised that the Arctic is STILL AN even with the record high +AO and very long strong +AO preceding it! This is disappointing.

Throughout Earth’s History, Solar System Processes Controlled the Carbon Cycle
The world is waking up to the fact that human-driven carbon emissions are responsible for warming our climate, driving unprecedented changes to ecosystems, and placing us on course for the sixth mass extinction event in Earth's history. However, new research publishing this week in the leading in

"The United States saw the largest decline in energy-related CO2 emissions in 2019 on a country basis – a fall of 140 Mt, or 2.9%, to 4.8 Gt. US emissions are now down almost 1 Gt from their peak in the year 2000, the largest absolute decline by any country over that period."

So with talk that warmer more humid weather deters the spread of viruses doesn't that kind of fly in the face of GW? Just food for thought....

Nah cause insects that carry viruses and parasites will be moving north as it gets warmer which will more that make up for it.

SER ftl. Increased MJO phases 4 and 5 frequency due to warmest waters being in and near Indonesia, which results in increased/stronger SER.

Wow, we weren’t the only ones blazing. I know everyone is rightfully concerned about Coronavirus right now, but we need to not forget other even greater threats. I was out cycling this afternoon and saw a large group of children in bathing suits running through a sprinkler, on March 20th! The world is changing in many ways and like the Coronavirus, we need to make some difficult changes now, not in the future.

CO2 emissions are down drastically thanks to the virus.

What has it done to the atmospheric CO2 levels? I assume it would take years of reduced emissions to noticeably drop the current concentrations.

I have no Idea but the plants are soaking it up now due with the growing season starting.

I've been wondering lately. With so many countries around the world shutting down all but essential travel, how's our CO2 coming along? Whatever we believe about AGW, I think we can all agree that less pollution is a positive.
I don’t have numbers on hand, but you can bet CO2 emissions are way down over the last few months.

No Doubt they are, but just wait till these Quarantines are lifted and the rubberband snaps back.

Once all these glaciers that are unstable start plunging into the sea it will make this virus look like nothing as far as disruption goes. I have zero confidence in humanity after the way this virus was handled by ignoring the warnings.

Bill Gates: How the coronavirus pandemic can help the world solve climate change
Billionaire philanthropist Bill Gates says the coronavirus pandemic is forcing some of his climate change work to the back burner, but the work being done fighting the coronavirus is also paving the way for future climate change work in productive ways.
However not everyone is so sure the global community will apply learnings from the COVID-19 response to climate change.
"COVID-19 may deliver some short-term climate benefits by curbing energy use, or even longer-term benefits if economic stimulus is linked to climate goals — or if people get used to telecommuting and thus use less oil in the future," said Jason Bordoff, a former U.S. National Security Council senior director and special assistant to President Barack Obama in an op-ed published in Foreign Policy on Friday. "Yet any climate benefits from the COVID-19 crisis are likely to be fleeting and negligible," he said.
Instead, the issues with keeping the pandemic under control indicate that solving climate change will be virtually impossible. "The pandemic is a reminder of just how wicked a problem climate change is because it requires collective action, public understanding and buy-in, and decarbonizing the energy mix while supporting economic growth and energy use around the world," said Bordoff, who is now a professor and founding director of the Center on Global Energy Policy at Columbia University's School of International and Public Affairs.

If it never gets cold or snows again... it's still not Global Warming. Maybe it just because God doesn't want us to have snow anymore.
Huh?
I. KATL Going from 1961-1990 to 1991-2020 in the means:
A. KATL lows:
- Dec: rose from 35.0 to 38.3 (+3.3)
- Jan: rose from 31.5 to 35.4 (+3.9)
- Feb: rose from 34.5 to 38.8 (+4.3)
- DJF: rose from 33.7 to 37.5 (+3.8)
B. KATL highs:
- Dec rose from 54.0 to 55.7 (+1.7)
- Jan rose from 50.4 to 53.6 (+3.2)
- Feb rose from 55.1 to 57.9 (+2.8)
- DJF rose from 53.2 to 55.7 (+2.5)
Note that winter lows rose faster than highs did. I attribute this to the increase in the airport warming effect due to weaker radiational cooling as time has gone on.
--------------------------------------------------
II. KAHN (Athens, GA, where they don't have the KATL airport warming effect on lows):
A. KAHN lows:
- Dec: rose from 35.0 to 36.4 (+1.4)
- Jan: rose from 31.9 to 33.9 (+2.0)
- Feb: rose from 34.5 to 37.0 (+2.5)
- DJF: rose from 33.8 to 35.8 (+2.0)
Note that winter lows went from 0.1 warmer than KATL for 1961-90 to a whopping 1.7 colder than KATL for 1991-2020, a clear indicator of the KATL warming effect for lows. So, this tells me increased warming effect of KATL for mean winter lows has likely been nearly 2F over last 30 years. This is independent of GW.
B. KAHN highs:
- Dec rose from 55.0 to 56.3 (+1.3)
- Jan rose from 51.6 to 54.2 (+2.6)
- Feb rose from 56.2 to 58.3 (+2.1)
- DJF rose from 54.3 to 56.3 (+2.0)
- Note that unlike KATL, winter lows rose the same amount as highs. This makes sense since KAHN doesn't have the airport related warming effect on lows.
- Since at KAHN winter lows and high both rose 2.0 F, I am guessing that GW caused N GA winters to warm ~2 F over the past 30 years.
- Note that KAHN highs remained warmer than KATL highs. That's because the airport effect is minimal for highs and the lower elevation of KAHN (219 feet) vs KATL has always favored warmer highs at KAHN (more downslope). That's even after figuring that highs when there's all day long CAD likely average 1-2 colder at KAHN.

AGW is still raging with the virus taking the spotlight. We were one of the few places on the planet below normal for May while Siberia roasted with temps reaching the 80s above the arctic circle.

May 2020: Global temperatures tie for record hottest
May 2020 tied with May 2016 as the warmest May on record for the globe, continuing 2020’s streak of having every single month either be the warmest or second-warmest month on record

Not a big fan of using single events as evidence for AGW, but this one is pretty special and unusual: https://www.cbsnews.com/news/arctic-records-its-hottest-temperature-ever-2020-06-20/
