Such a rapid expansion of tar sands development is part of a global energy scenario that would
push average global temperatures as high as six degrees Celsius by the end of the century.
The increase in carbon dioxide levels recorded so far has played the most important role in
pushing average global temperatures up by 1 °C (1.8 °F) during the last 200 years.
Not exact matches
Even so, the IPCC estimates above indicate: 1) Total Net Atmospheric Carbon Emissions to 2100 will amount to ~ 2050 PgC (or more) on current Trends, 2) A BAU projected estimate would
push CO2 to ~ 952 ppm by 2100 (or more), and 3)
Global average temperature increase / anomaly would be as high as ~ 6.8 C by 2100
Dana, I think you are
pushing in the right direction with this; heat content is a much more direct measure of the underlying changes to the climate system than
average air
temperatures and climate science communicators should make heat content their first response to the suggestion that
global warming is something that waxes and (allegedly, recently) wanes.
But the data released today confirm that human - induced
global warming is
pushing temperatures higher at an alarming rate: 2014 was the previous record holder for
global average surface
temperature, clocking in at 0.57 °C above the 1960 to 1990
average, but last year was 0.75 °C above that
average.
(Those of you still misleadingly
pushing TSI /
global average temperature regressions: You're making false assumptions and your residuals do not pass careful diagnostics.
As the CO2 control knob
pushes the external forcing ever higher, the
average global temperature has to increase to compensate.
Policymakers should carefully consider the timescales that are relevant to GHG mitigation efforts, especially given the recent international
push to maintain
average global temperatures within 1.5 — 2 °C of the pre-industrial mean (Fearnside 2015).
Currently, human warming by Greenhouse gasses has
pushed global average surface
temperatures into a range about 1 degree Celsius hotter than the 1880s.
It is your icons in the «climate science consensus» community that
pushed supposedly
global surface air temperatures (occasionally combined with supposedly global sea surface temps) as «Global Average Temperature.&

global sea surface temps) as «
Global Average Temperature.&
Global Average Temperature.»
Greenhouse gas emissions from coal, gas and oil combustion since the dawn of the 19th century and the coming of the machine - age century have
pushed carbon dioxide ratios in the atmosphere from less than 300 parts per million to 400ppm everywhere, and
global average temperatures have risen by 1 °C.
