Hilarious that you posted left wing sources to show that you fell for the media lie. Go back and watch the original videos They are not saying that Covid 19 is a hoax. They are saying that democrat's are trying to take advantage of the situation. You should be embarrassed that you are that gullible that you just took MSNBC's word for it without looking into it yourself.

UPDATE: Climate experts tell us that reducing CO2 emissions will slow the rise of atmospheric CO2 levels. However, compared to the previous year, atmospheric CO2 levels have risen FASTER as of 3/26 in spite of a massive worldwide reduction in CO2 emissions over the past two months.

Data: CO2 levels vary seasonally from a low in September to a high in May-Early June. So far this year, the 3/26 weekly is 7.56 ppm higher than the 2019 low. For the same period last year, the 3/26 weekly high was only 5.93ppm higher than the 2018 low.

What does this mean? We won't know until June, but so far, observed data does NOT support the premise that the rise in atmospheric CO2 levels is primarily manmade. In fact, atmospheric CO2 levels are rising faster than the same period last year in spite of a dramatic worldwide reduction in CO2 emissions.

Caveat: Atmospheric CO2 levels fluctuate more in Feb-Mar than other months so we need a couple more months of data to see if this trend continues.

(To see 2-year data, you'll have to go to the Interactive Plot link on this page.)

Science "experts" and global warming alarmists wrong yet again? Color me shocked.

Just like with the incompetent statistics the health "experts" compile for the coronavirus that only look at people they test rather than randomization of the whole population, global warming alarmists wrongly generate misleading statistics of only the last 100 years when the Earth is billions of years old.

Hopefully we’ll see the bigger picture, in the wake of the pandemic, that change from our current lifestyle is not only possible but necessary.

Yeah but how do you account for the gigantic bushfires from earlier? And the fact that brazil went nuts with the rain forest last year as well?

Should I even mention that the phytoplankton population has been decreasing for years ? They're responsible for the biggest amount of carbon fixation in the biosphere.

6months is not enough for the biodiversity to be restored after decades of overuse. And it so the biodiversity that is a big factor in carbon fixation. So yeah they're will be a lag in the carbon curves even if we reduce drastically carbon emissions. Probably a few years..

I just think this is an oversimplification of the situation. Hopefully it will have an effect, but more importantly hopefully we will keep some of the changes made to our lifestyles lately..

I think we'll see a global slowdown through April for sure. Unless warm weather kills off the coronavirus, we could see a slowdown for many months.

I've heard that natural events have affected atmospheric CO2 levels, but I'm not knowledgeable enough to know what those effects have been in the past.

Since it's impossible to create such a draconian reduction in CO2 levels voluntarily, this is a great opportunity to see what happens when CO2 is actually reduced.

Note that there is a lot of noise in the Feb-March data and I didn't go back further than two years to see what the annual low to high has been historically. I assume that if there is something to be seen here, either the pro or con side of the AGW debate will run with it this summer.

UPDATE: For the week ending Apr 4, the weekly average was 7.78ppm higher than the seasonal low back in September compared to a 6.62ppm rise the previous year.

In spite of a draconian worldwide reduction in CO2 emissions, atmospheric CO2 levels continue to increase faster than when nations were pumping out CO2 at far higher levels last year. Since atmospheric CO2 levels tend to peak in mid-May, I'll continue to update this thread until then.

How much have CO2 emissions been reduced?

Another Leftist speaking point that is getting old. Science has become so infiltrated with politics that the truth is hard to find. If you think that scientists are some benevolent beings and can't be influenced by political ideology (and funding), you are blind, an idiot, or both. Both sides of the political aisle are guilty. Now you can go back to calling conservatives dumb, and patting your intelligent selfs on the back.

As far as the thread title, if science shows that man has little to no impact on climate change, I guarantee you that the Left will still find some "science" backing their beliefs. All hail to the Church of Climate Change!

It's kind of astonishing how closely the denier arguments line up between COVID-19 and climate change.

"Look only 10 people,...er 100 people....er, 1000 people a day are dying...no big deal...people have been dying for thousands of years!"

also ignoring things like rate of change

people still clinging to the idea that it's just the flu, even though even with extreme measures taken COVID -19 is on it's way to killing almost as many people a few weeks as the flu does in a typical year. Claiming it's just the flu at this point is moranic.

Proof positive that these people will still cling to denying climate change is happening right up to the end.

Why is it still climbing?

Because the SJWs changed the name from global warming to "climate change". Now, any time any thing changes, they get to be right! It's an argument they can't lose!

Good lord, if you think it's just a problem that instantly goes away the moment we start driving less for a few weeks no wonder you don't think we need to do anything about.

UPDATE: For the most recent weekly data ending 4/9/2020, the weekly average was 8.49 ppm higher than the previous year's low compared to a rise of only 7.75 ppm for the same week in 2019. Atmospheric CO2 levels continue to rise unabated in spite of the continued dramatic reduction in CO2 emissions.

I'll continue to update this thread until mid-May.

The source for data is here. You will have to navigate to the interactive plot page to see the updated weekly data.

Stop picking our sing data points. Follow trends over a few months. Or even longer if this continues for a year or two. Account for other factors. And then make an assessment.

On 3/25, I posted that contrary to AGW theory, atmospheric CO2 levels were continuing to arrive in spite of massive reductions in manmade CO2 emissions. On 4/14, three weeks later, this failure of AGW theory hit national awareness with an article on what is probably the world's largest contrarian climate change website. (see below)

"On April 8th, the Mauna Loa Observatory released their report on the previous month’s (March 2020) concentration, and the data was shockingly contrary to what I and others had expected. Not only was there no decrease in the level of atmospheric CO2, the rate of increase continued unchanged." ..."The lack of an effect whatsoever on global CO2 levels after the huge decline in emissions should be a wakeup call to any of the politicians advancing economically crippling measures like the Green New Deal or the Paris climate accord."

Note that the author (and I) were surprised to see atmospheric CO2 increasing unabated. More informed readers (in comments in an earlier article) pointed out that humans are only responsible for 4% of global CO2 emissions. We are now seeing that is apparently true.

typo "continuing to rise"

I really wish we had a 60-second edit after post feature on letsrun.

If carbon emissions goes down, the rate of increase of CO2 levels should, in fact, go down instantly, if the common climate change hypothesis is true. But obviously climate change activists such as yourself don't want to see hypotheses tested. That would be too much like science.

As of 4/26, the most recent weekly atmospheric CO2 level has gone down slightly from 416.45 to 415.88. For the first time since CO2 emissions dropped sharply, we are seeing a confirmation of AGW theory with a decline in weekly atmospheric CO2 levels as CO2 emissions remain reduced.

The NOAA is now following this, too, and has a comment at the top of the page I keep posting. They confirm that we should see a decline.

CO2 levels peak in mid-May. It will be interesting to see if this pause in rise of CO2 levels continues until then. I'll post updates to this thread periodically.
