- In 2008, the Earth's oceans became more acidic than they ever were between 1860 and 2005. The oceans have absorbed about half of the carbon dioxide emitted from human activity since the Industrial Revolution, Climate Central reports. That absorbed carbon makes the water acidic, which is harmful to many marine species.
- Different parts of the world will exceed their historical highs at different times. The first to feel global warming's unprecedented changes will be the tropics. That's concerning because so many of Earth's species live in the tropics. Also, many tropical countries are low-income and may not have the resources to deal with hits to fishing or agriculture from climate change.
