PPT-Chapter 2 | Our Changing Climate

Key Message 1 2 Ch 2 Our Changing Climate Global climate is changing rapidly compared to the pace of natural variations in climate that have occurred throughout Earths history Global average temperature has increased by about 18F from 1901 to 2017 and observational evidence does not support any credible natural explanations for this amount of warming instead the evidence consistently points to human activities especially emissions of greenhouse or heattrapping gases as the dominant cause. 4 Projecting Future Climate H ow much temperatures rise depends in large part on how much and how quickly heat-trapping emissions accumulate in the atmosphere and how the climate responds to these Climate. Part One . A very personal concern . . book research and years of observing nature have made me very aware of seasonal change and “what is normal” . a growing awareness that the usual dates of events in nature are changing, as well as the numbers and kinds of many plant and animal species . for flood risk. Dennis P. Lettenmaier. Department of Geography. University of California, Los Angeles. Climate Roundtable, “Precipitation in the U.S.”. FM Global, Boston. Jan 12, 2015. Motivating question: As the climate (and presumably precipitation and precipitation extremes) change, what will happen . Part Two . SUMMER . . . Average summer temperatures are expected to rise from 4 to 8 C . More extreme weather is predicted – summer heat, windstorms, drought and severe rainstorms . . .
