There IS a problem with global warming... it stopped in 1998

GOOD NEWS!

Arctic sea ice extent is now greater than it has been since 2013.

 

What do you think that means?  Are you saying that sea Arctic Sea Ice is a measure of the effects of global warming?

"Arctic sea ice appears to have reached its annual maximum extent on March 5. The 2020 maximum sea ice extent is the eleventh lowest in the 42-year satellite record, but the highest since 2013."

And down south

"Since satellite-based measurements began in the late 1970s, Antarctic sea ice extent has shown high year-to-year variability. The overall trend is towards long-term increase" NOAA

So in other words, 7 of the lowest 11 in the last 42 years were the last 7 years (since this year's stellar performance is still one of the 11 lowest). Without even looking at the graph, sounds like sea ice is, in general, going down.

Or it is coming back, part of a natural ebb and flow cycle.

It's a pity people with no scientific background are unable to read graphs or interpret the literature.

But once again, we have proof right here.

Just what part of "Arctic sea ice extent is now greater than it has been since 2013" did I misinterpret?

If it were coming back then the extent would be greater than the average, not less than it.  This data point if taken alone or even compared to 2013 could at best be a mark towards a slower rate of loss but not a reversal.  There is about a 5 year cycle, see graph below.  March is the maximum, September is the minimum.  As you can see, both are trending towards decline.

This isn't the stock market, guaranteed to go back up eventually. Well, maybe it is, but "eventually" probably means a lot more years that matters to us.

You know, that didn't even occur to me that he would mean 20,000 years. Rush, our fisheries don't have 20,000 years.
