What do we know

about climatechange?

THE GREENHOUSE

EFFECT

1. CO2 and other greenhouse gasetrap heat from the sun in ouratmosphere.


4/68

Before the IndustrialRevolution, for thousands of

years, the amount ofcarbon in the atmospherewas at 287ppm


5/68

Now, after three centuries of burningcoal, oil, and gas, we're at 390ppm

thats above any levels weve seen inrecorded history.

If humanity wishes to preserve a

planet similar to that on whichcivilization developed and towhichlife on Earth is adapted,

paleoclimate evidence and ongoing

climate change suggest that CO2 willneed to be reduced from its current387ppm to at most 350ppm.

In fact, 117 of the most vulnerableisland and African nations weresupporting 350ppm, saying it is

'necessary for their survival,

yet they were not the 117 that have thepower. The biggest, most powerful

emitters were not ready to really take

action.

At the end of the conference, despitea lot of pressure, the rich countriesrefused to commit to what scientificfindings indicate is necessary so

what next?

so how do we get backto 350ppm and avoidclimate catastrophe?

According to Jim Hansen and otherscientists the main things we need to do

right away are:

Stop coal use by 2030

Improve agricultural and forestrypractices Dramatically reduce the use of allother fossil fuels

If we manage to accomplish these

things, we could get back to 350ppm by
