110 million tons of manmade global warming pollution is released into the atmosphere every 24 hours and is building up and trapping heat.

The main source and cause of the rising global temperatures we see today is the result of the burning of fossil fuels.

On a global basis, more than 90% of all the extra heat energy trapped by our atmosphere in going into the oceans.

The extra heat being trapped in our atmosphere is changing our precipitation patterns causing extreme flooding and drought in places around the world.

Heat stress is beginning to decrease crop yields from rice, corn and soybeans and exposure to higher levels of CO2 is decreasing the nutrient content of many staple crops such as rice, wheat and soy.

As our world gets warmer and wetter, the range of tropical diseases expands, meaning there are more places for tropical diseases to take root. Tropical diseases include, West Nile Virus, Chikungunya, Chagas Disease, Dengue Fever and Zika Virus
