NOAA/NCDC released a whole slew of rather grim climate news today. It’s important to remember that besides the sun and increasing greenhouse gases there is a lot of built in variability in the climate system. It’s only been in the last couple of decades that the greenhouse warming has risen out of the noise created by weather.
That said, even with El Nino gone and the sun coming out of one of it’s quietest periods of the century, the temperatures have soared. The last 4 consecutive months have been the hottest on record. The first 6 months of the year are also the hottest on record.
The mid tropospheric temps from UAH and RSS are also running near or above the warmest ever on their much shorter record.
The Arctic sea ice also continues it’s decline. The rate of decline in June was the fastest ever measured.
The Antarctic is actually gaining ice due to a complex weather pattern induced by ozone depletion and cooling in the stratosphere. This cooling is also caused by increasing greenhouse gases.
