PRESENTATION OUTLINE
WHY WE'RE THE LAST GENERATION
THE SCIENCE BEHIND CLIMATE CHANGE
" Multiple studies published in peer-reviewed scientific journals1 show that 97 percent or more of actively publishing climate scientists agree: Climate-warming trends over the past century are very likely due to human activities."
- NASA
"The reason that the Earth is warm enough to sustain life is because of greenhouse gases in the atmosphere. These gases act like a blanket, keeping the Earth warm by preventing some of the sun’s energy being re-radiated into space."
- Skeptical Science
EFFECTS OF CLIMATE CHANGE
" As climate change impacts rainfall patterns and rising sea levels increase the salinity of groundwater" "Tuvaluans can no longer rely on drinking groundwater and depend almost entirely on rainwater collected an stored in tanks."
- Global Environmental Facility
" More extreme temperature and precipitation can prevent crops from growing. Extreme events, especially floods and droughts, can harm crops and reduce yields."
- EPA
WHY HASN'T MORE BEEN DONE
"One cause of the delayed response is that when scientists started talking about the mounting evidence of global warming in the 1980s, powerful interests vested in fossil fuels wasted no time in executing a very effective campaign to muddy the waters."
- Larry O'Hanlon
"Most Americans have never learned the basics of climate change at school," "People have had to put together their own information. At the same time, 1 in 4 people in this country are students."
- Mark McCaffrey
HOW LONG DO WE HAVE TO DO SOMETHING?
" a global average atmospheric concentration of carbon dioxide (CO2) of 450 parts per million (ppm), could set in motion unprecedented changes in global climate and a significant increase in the severity of natural disasters—and as such could represent the dreaded point of no return."
- The Scientific American
WHAT SHOULD WE DO TO COMBAT CLIMATE CHANGE
"a fee placed on greenhouse gas pollution mainly from burning fossil fuels."
- The David Suzuki Foundation
According to the Pew Research Center Climate Chang is perceived by the global community as the greatest challenge facing humanity.
