Global Warming & climate change

Climate change/observation that the earth's temperature has increased by ~.8degrees celsius in the last 100 years.

significant and persistent change in statistical distribution of the state of the atmosphere or ocean

global warming

-Clmate is the average state of the atmosphere or ocean, climate is what you expect, while weather is what you get.

- weather is the state of atmosphere or ocean at a point in time. However weather is chaotic and cannot be predicted more than 2 weeks into the future.

it is a single temperature calculated by averaging earth's surface temperatures from stations all accross earth.

departure from longterm average.

current one

• -decline in mountain glaciers/snow cover
• -Reduction in Northern Hemisphere sea ice.
• -troposhere warming, stratosphere cooling.
• -increase in water content.
• -Sea level rise.
• - Higher energy/temperature content in oceans

More intense storms, drought, heat wave, ocean acidification, coral bleaching

this is also  an impact of climate change - thinner ice implies fewer places to rest and forces calves and their mothers to swim farther north. This exerts energy which puts them at a greater risk for starvation or predation for the calves.
