Ratty, How much CO2 is being emitted into the atmosphere each year by volcanoes? Any emissions into the ocean are another category since the oceans aren’t emitting CO2 on a net basis.
Duwayne, Robyn Wylie's article is about terrestrial degassing of CO2.
Ratty, I'm glad to see you are looking into the Vocanic CO2 emissions. And I like numbers. Robyn Wylie's estimate for terrestrial Volcanic emissions appears to be about 0.6 billion tons per year. For perspective, this is equal to about 3.5% of the annual growth in atmospheric CO2.
Greenland's ice sheet is becoming smaller and smaller. The melting takes place with increased strength and at a speed that no models have previously predicted.
No - although there is recent melting it has not cut into the huge gains in the last parts of 2017 The vast majority area of Greenland has seen surface snow and ice gain over the past 9 months. Moreover, Arctic temperatures for now are below normal.
Winter snow and ice cover trend for the Northern Hemisphere has in fact been trending upwards since statistics started. And when one applies the 30-year weather mean used to define climate, the winter trend since 1987 is strongly upwards. So is the autumn trend. This 2017 winter was well above average, ranking in the top 10.
The vast majority area of Greenland has seen surface snow and ice gain over the past 9 months. Moreover, Arctic temperatures for now are below normal...The big development in recent Arctic news is the “recovery” of Arctic sea ice extent, which now is back in the normal range.
