Document Summary
Scie 1p50 lecture #14 monday, october 31st, 2016. Climate influences everything around us: affects our agriculture. The fifth assessment report of the intergovernmental panel on climate. Change (ipcc) 2014 made it clear that: each of the last three decades has been successively warmer at the earth"s surface than any preceding decade since 1850. Northern hemisphere, 1983-2012 was likely the warmest 30-year period of the last 1400 years : climate change is the fastest-moving area of environmental science today. Puts together conferences to try & agree on what to do with climate. Climate = an area"s long term atmosphere conditions. What is climate change: temperature, moisture content (how much water is out there), wind, precipitation (rain, snow, ice), etc. Weather = conditions at localised sites over hours or days. Global climate change = describes trends and variations in earth"s climate: temperature, precipitation, storm frequency, etc. As earth"s surface absorbs solar radiation, the surface increases in temperature & emits infra-red radiation.
