Some eye opening tidbits in here:
"The 10 warmest years on record have all occurred since 1997"
"Several scientists said the most remarkable thing about the 2014 record was that it occurred in a year that did not feature El Niño"
Of course all of this is in relation to a history starting only in the late 1800s, so we are looking at a blip on geological time scales, but still even micro-cycles within macro-cycles can be instructive and meaningful. Would like to hear from the experts on the macro view.
- jjoonathan 12y agoNot an expert, but the wiki page seems pretty accessible http://en.wikipedia.org/wiki/Temperature_record http://en.wikipedia.org/wiki/Temperature_record Satellites: 35 years Balloons: 65 years Instruments: 165 years Ice cores: 800,000 years Sediment cores: at least 500,000,000 years http://en.wikipedia.org/wiki/Geologic_temperature_record#mediaviewer/File:All_palaeotemps.svg http://en.wikipedia.org/wiki/Geologic_temperature_record#med...
- gus_massa 12y agoIt' not very clear, but the "on record" probably include only the instrument measurement period, or something like that. The ice cores graph (linked near the bottom) says that 125.000 years ago the temperature was much hotter (+8°C). http://en.wikipedia.org/wiki/Temperature_record#mediaviewer/File:EPICA_temperature_plot.svg http://en.wikipedia.org/wiki/Temperature_record#mediaviewer/...
- mark-r 12y agoThe rate of change probably matters as much as the absolute difference. Given enough time, life can adapt. I'd love to see a chart of both the temperatures and the rate of change over those time periods.
- phaemon 12y agoNote that these are Antarctic temperatures (as you might guess from "ice core"), not global temperatures.
