Alaska

Alaska is experiencing fast and expansive consequences of climate change, resulting in an increase in greenness in Arctic areas.

As the Arctic gets hotter, its landscape releases more greenhouse gases. According to a new study, the warming Arctic soil's bacteria may diversify and emit even more greenhouse gas than scientists have thought.

As the Roman Republic began to fall, the Earth suffered from extreme cold and famine that helped push Rome's instability to its ultimate collapse. The cause of the extreme climate? The eruption of an Alaskan volcano on the opposite side of the world.
