The atmosphere has a natural supply of "greenhouse gases“
They capture heat and keep Earth warm enough for us to live on.
greenhouse effect Without the
the planet would be an frozenuninhabitable, wasteland.
Over the past 300 years, people started emitting large amounts of greenhouse gases
More and more fossil fuels were burned More and more fossil fuels are being burned
to run our cars…
And F A C T O R I E S
Adding to our natural supply of greenhouse gases.
The gases can stay in the atmosphere for at least 50 years and up to centuries.
the globe has heated up by about one degree Fahrenheit over the past century.
One degree not a big deal? Consider this…
the difference in global average temperatures between modern times
Arctic ice is rapidly
Polar bears and indigenous cultures are already suffering from the sea-ice loss.
Glaciers and mountain snows are rapidly melting Glaciers on mountains are slowly melting.
Coral reefs which are highly sensitive to small changes in water temperature
Suffered the worst bleaching-or die-off in response to stress- ever recorded in 1998
We only have one beautiful planet Earth.
And we are all affected And we are all being affected.
