Be sure to catch Cosmos this week as Neil deGrasse Tyson discusses the planetary-scale significance of climate change and refutes a number of global warming denier talking points. Sneak preview: the difference between weather and climate: Here’s the difference between weather and climate. Weather is what the atmosphere does in the short term. Hour to hour, day to day. Weather is chaotic... Climate is the long term average of the weather over a number of years. It’s shaped by global forces that alter the energy balance of the atmosphere, such as changes in the sun, tilt of the earth’s axis, the amount of sunlight the earth reflects back to space, and the concentration of greenhouse gases in the air. A change in any of them affects the climate in ways that are broadly predictable. motherjones/environment/2014/05/cosmos-tyson-sagan-climate-change-episode
