So, what is global warming and what’s the problem anyway?
The science is clear: global warming is happening faster than ever and humans are responsible. Global warming is caused by releasing what are called greenhouse gases into the atmosphere. The most common greenhouse gas is carbon dioxide. Many of the activities we do every day like turn the lights on, cook food, or heat or cool our homes rely on energy sources like coal and oil that emit carbon dioxide and other heat-trapping gases. This is a major problem because global warming destabilizes the delicate balance that makes life on this planet possible. Just a few degrees in temperature can completely change the world as we know it, and threaten the lives of millions of people around the world. But don’t give up hope! You can help stop global warming by taking action here at 350.org.
Either way you slice it, in terms of CO2 or CO2-e, 350 is the mark of a completely new direction—and the movement that will get us there.
These considerations have led 350.org to see the 350 ppm target not only in terms of CO2, but CO2e. On a technical level, this becomes a more ambitious target, incorporating other greenhouse gases. On a practical level, it signifies the same priorities 350 has embodied all along. Any climate target lower than where we are right now (more…)
