Will Coronavirus give us key insights into global warming debate?

Is human activity causing atmospheric changes affecting global climate?

Absolutely.

If humans were doing nothing, would climate still see long-term, significant change?

Yes. And it's been happening for billions of years.

Human activity is only one of many, much broader factors which vary climate (temperatures, sea levels, etc.)

In past, Earth's atmosphere varied between near-zero percent oxygen to over 30% oxygen, the latter condition giving rise to super large animals/insects and widespread climate-changing forest fires.

Continental drift, their positions and subduction (creating mountain ranges, inducing vulcanization) - these have huge impact on regional climate; seasonal monsoons, creation of deserts, and such.

Before humans, Earth has been a tropical hot house and at other times a "snowball".

Only a few thousand years ago, most of North America was blanketed with miles-thick Glaciers.

There are varying and predictable variations in solar energy reaching Earth, creating cycles of Ice Ages, with a period of about 41,000 years.

The Earth's orbit is elliptical and subject to resonant perturbation from Jupiter and other planets.

And Axial tilt is also variable, with over 3 degrees change in about 20K years.

These combine in a pattern of orbital precession, drastically varying solar energy to regions and overall.

Through it all, there has been life on Earth almost 4 billion years, basically since Oceans and land formed (albeit with several mass extinction events).

And the Sun's energy output itself has varied, increasing overtime, as the star "matures".

The Earth will be here and doing fine long after humans are gone or extinct.

This isn't an invitation to reckless environmental stewardship, but neither should we overestimate our control and impact.

We need to get over ourselves.

Will Covid-19 drive changes in human understanding or behaviour which affect climate? Not one bit.

bear that in mind as the results play out over the next few weeks.

No one is saying COVID-19 is a hoax. They are saying the end result of shutting everything and preventing it is worse than letting it run its course. And that very well could be true. I had a house cleaner begging me to not cancel on them because they are so desperate right now, so we didn't cancel. The people who are already working the lowest paid jobs to put food on the table are the ones hurting the most right now.

Your opening sentence is wrong, plenty of American conservative commentators have labeled it a hoax. They’ve generally backed away from that bold prediction now, but plenty did.

Don’t make us show you the evidence. Of course as a result their minions followed suit.

There is no debate. On the one hand, you have very smart, honest people who know a lot about science telling us the truth about climate change. On the other hand, you have a bunch of English majors and Texans who get their "alternative" facts from Rush Limbaugh.

Just curious if the hundreds of illegal immigrants that trump has working at his failing golf courses get the $1200.

One of AGW's major theories will be proven or disproven in the next two months. That premise is that the rise in atmospheric CO2 levels is directly related to the rise in manmade CO2 emissions.

Whoa there. That's starting to sound like science. I don't think the Global Warming people will be too open to that.

This argument presumes that it is not possible to manage both the economic and health side of the COVID 19 crises. But lots of countries are managing this crisis without considering for a second whether to force people to go back to work and roll the dice with coronavirus exposure. S. Korea, Russia, and China have managed the crisis. The Nordics are and Euros are ensuring that rents and utility bills are suspended while guaranteeing income for displaced workers. The US and Brazil are really the only countries that are considering throwing their population to the ravages of this virus without even considering whether it is feasible to take responsible measures to lockdown the population and have the government compensate everyone during the shutdown.

Um no, fisky is very much an AGW skeptic.

Bro last glacial maximum was 23,000 years ago.

There is one unifying theme between COVID-19 idiots and Climate Change idiots: they cannot examine rates and values independently.

To them, if X is BIGGER than Y, that's all that matters, regardless of how fast X or Y is changing/did change in the past.

It's amazing

Please do show the direct evidence, I don't think you have anything except things that have been twisted by the media.

So Fisky says that if nothing changes, climate change is a hoax.

If CO2 levels drop then it is still probably a hoax.

That's not what he said at all. Read it more carefully.

No that is what he said.

Sure, if you want to get all nit-picky... glacial maximum was roughly 20,000 years ago, but it took over 10,000 years for (North American) ice sheets to abate, with some persisting until about 5,000ya A better phrase would have been "scant thousands of years ago..."

It is amusing when posters not only use the wrong word, but use the complete opposite of their intended word.

Guess that really sucks for socialism and communism which involves even more labor with an added bonus of enormous waste

It's also amusing when someone corrects language and grammar on the internet but has no idea what they are talking about. Be a descriptionist, not a prescriptionist brah.
