However, the model results are important because they show that, in all likely scenarios of future
greenhouse gas emissions,
record daily
highs should increasingly outpace
record lows over time.
To suggest that because near surface temperatures have flattened at or near the
highest on
record requires «abandoning» a sinking ship is to be grossly underinformed about the full scope and scale of the multiple changes going on and the confidence that anthropogenic climate continues unabated as it will so long as humans continue to increase
greenhouse gas concentrations.
Finally, the fact that both the oceans and the atmosphere are at their all time
highest temperatures over the past 10 year average from instrument
record and through extrapolation to near - term paleodata, we can see a remarkable consistent effect of what increasing
greenhouse gases do to overall alterations in Earth's non-tectonic energy storage.
NOVEMBER 13, 2017 Tobias Buck in Berlin and Lucy Hornby in Beijing 58 comments Stronger Chinese economic growth will push global

Both wetland drying and the increased frequency of warm dry summers and associated thunderstorms have led to more large fires in the last ten years than in any decade since
record - keeping began in the 1940s.9 In Alaskan tundra, which was too cold and wet to support extensive fires for approximately the last 5,000 years, 105 a single large fire in 2007 released as much carbon to the atmosphere as had been absorbed by the entire circumpolar Arctic tundra during the previous quarter - century.106 Even if climate warming were curtailed by reducing heat - trapping
gas (also known as
greenhouse gas) emissions (as in the B1 scenario), the annual area burned in Alaska is projected to double by mid-century and to triple by the end of the century, 107 thus fostering increased emissions of heat - trapping
gases,
higher temperatures, and increased fires.
