@ blumenkraft ….we got here because lots of people didn't take this seriously …...and it appears many still aren't
Guess we just got lucky having a woman in charge in New Zealand ….not to say that other countries haven't handled it well also
good luck everyone

The current pandemic could cause lasting climatic effects long-term if it accelerates the transition to a low carbon economy

@ pauldry600......2012 may remain at outlier....but for how much longer?
Current CO2 @ Mauna Loa 416 ppm
34 ppm to 450 ppm ….. 3ppm per year x 11.333 years = 34 ppm
450 ppm = Tipping Point

IF .....the 2020 average drops to 2million sq kms .....and we have an extreme loss .....similar to 2012 ...then we could be close to 1 million sq kms at the minimum.
The 2020's are only 7 months away.

the ice melt will happen much faster than the rebound of the land.....for example parts of Scotland are still rising as an after effect of the ice sheets melting

but have I missed it, or has the increase in sea level rise from 3mm / year to 5 mm/year not been verified yet?

@ bill fothergill............looking at your longterm graph this is perhaps an argument to be made that AGW started approximately 8000 years ago with the spread of agriculture as witnessed by the significant spike in temperature at that time .....and that our activities since then have held the temperature up higher than they would have been without our ever increasing disruption of the planets ecosystems

if you look at the long term temperature graph ....for global average temperature...the step up after the 1998 El Nino is obvious...only the la Nina years of 1999 and 2000 are below the previous global record year 1997.......and since 1998 the positive feedbacks have started to have an increasing effect

the only valid period offered is 1981-2010......as that is the only 30 year period on offer
....otherwise I would have suggested 1979-2008
as I'm sure most people know 30 years is the accepted time period for validating changes in climate
