Overall, we’re running quite close to the projections made in 2000 for carbon dioxide concentration, global temperature and sea level, Henson said.

Here’s a look at climate change indicators for 2020:

Carbon dioxide

Carbon dioxide is the greenhouse gas that scientists say is most responsible for global warming.

Since the early 1990s, the carbon dioxide level in the Earth’s atmosphere has jumped from about 358 parts per million to nearly 412…
