Here is the annual temp anomalies at the ground level (all of it since systematic global thermometer measurements began in 1880) from NASA’a GISS lab:
Notice we have risen about 1.1C = 2F since the pre-industrial baseline (which I’ll take as an average between 1880 and 1930). 2015 has been the highest ever. The trend since 1965 has been about 0.18C/decade.
GISS’s data:
Scroll to bottom and notice the over “100”s since Oct 2015 (never before reached). The last 5 months have been the hottest ever (globally).
Now for the Lower Troposphere temps (monthly) which also have recently risen very quickly.
UAH’s (Dr. Spencer’s) data reduction of the AMSU/MSU “satellite data”:
RSS (Dr. Mears') data reduction of same raw AMSU/MSU “satellite” data:
Both of these show Feb 2016 the hottest ever (and the full effect of the El Nino has probably not been felt)
Both show upward trends (.126C/decade for RSS and .15C/decade for UAH) since 1979 when the satellite data measurements began.
When the full El Nino is felt (probably this year) then we can run a line between the peak 1997 El Nino and the 2016 El Nino peak and we will have the trend of the upper bound of the satellite Lower Troposphere temps. Lower and mean trends will also show upward trends (~ .15C/decade).
Now I fully expect the temps will drop sometime in late 2016 or 2017 as the effects of the El Nino end. But we never see anything under 0.6C temp anomaly (ground GISS data) again unless there is drastic and longstanding (centuries) curtailment of ghg emissions. Only when we get that temp anomaly back to pre-industrial levels (< -0.2C) will we be able to say Global Warming has been “licked”.
Even in 2014 (before these latest big increases), Scientific American has pointed out a marked increase in Tick-borne disease (like may have caused my daughter’s paralysis) is due to global warming:
