WGU C264 - Climate Change. Lecture 33: Climate Change and Biological Consequences of Climate Change. Questions & Answers, VERIFIED. The 5 take home messages regarding global warming (e.g. how many degrees warmer compared to 1880s? The trend? etc.)? - -1. Since 1880, the average global temperature has increased about 0.8C (1.4F) 2. Two thirds of the warming has occurred since 1975 at a rate of roughly 0.15-0.2C per decade 3. Global warming does not mean the temperature is warmer every year (year to year) but the overall trend is that it is 4. Increased global temperature does not mean it is getting hotter everywhere 5. Extreme weather also increased as a result of increased global temperature (severe droughts, extreme precipitation events, coastal flooding, heat waves) T/F "global warming" does means it's getting warm everywhere - -F "global warming" does not mean that it is getting warm everywhere T/F Temperature increase is directly related to increased frequency and intensity of extreme weather - -T How many proxies did Michael Mann et al. used in 1997 to estimate the global temperature since 1400? - -1000 proxies Do we know how much the increased temperature is due to greenhouse g
