Climate Change

September 5, 2017

*We derive our energy from fossil fuels which are not renewable. The earth has a limited amount of natural resources.
*Sun is an open system of energy that we can gain.

Questions:
1. Must we change?
2. Can we change?
3. How we change?

Atmosphere is a sphere of outer space. It is the envelope of gases surrounding the earth or another planet.

Why earth get hot? 
-Sunlight
-As the CO2 concentration increases, more of the outgoing infrared radiation is trapped.

We are Dumping 110 Million Tons of Manmade Global Warming Pollution into the Atmosphere every 24 hours.

The biggest sources of greenhouse gases
-Coal mining
-Coal plants
-Thawing permafrost
-Oil production
-Air transport
-Fertilization
-Land Transport
-Landfills
-Industrial agriculture

*Cows (fart a lot, air pollution)
*The largest source of global warming pollution is the burning of fossil fuels.

-*Anomaly
-*Exponential curves (growth doubles up)

-Global surface temperature increasingly went up.
-The hottest year ever measured 2016.
-Ocean also got warmer.
(Death ocean; no life in the ocean)
-The Hydro-logical Cycle (evaporation, precipitation, surface on earth(rivers & seas))
-The same extra heat that evaporates more water from the ocean, causing bigger downpours and floods.
-Hotter years typically have more fires (For McMurray, Alberta, Canada)
-Glacier melt (declining ice mass in greenland)
-Sea level rise (miami)
-Climate change will likely lead to food and water shortages, pandemic diseases,disputes over refugees and,, natural disaster region cross the globe.
-Climate change is a medical emergency
-We now risk losing up to 50 % of all land-based species. (lost of habitats)
