Small changes in climate are enough to destabilize nations

1. Seemingly small global temperature increases are already having huge impacts, including intensified drought, flooding, and severe weather.

 

2. As sea levels rise, glaciers melt, oceans acidify, forests die, farmland turns into desert, refugees cross borders, and diseases proliferate, our hyper-connected human civilization has become increasingly unstable.

3. The threat climate change poses to agriculture is particularly daunting.

 

4. Past civilizations have collapsed under the weight of mass agricultural failure.

*Seemingly small global temperature increases are already having huge impacts, including intensified drought, flooding, and severe weather. As the American Association for the Advancement of Science put it,  “We are at risk of pushing our climate system toward abrupt, unpredictable, and potentially irreversible changes with highly damaging impacts.” Even the early effects of climate change are already rendering millions of people homeless. As temperatures have warmed, tropical diseases such as West Nile Virus have moved North.

*As sea levels rise, glaciers melt, oceans acidify, forests die, farmland turns into desert, refugees cross borders, and diseases proliferate, our hyper-connected human civilization has become increasingly unstable. Regional water, food, and resource scarcity have helped breed civil unrest and terrorism in Africa and the Middle East. We are already seeing this devastation take place in Syria, where an epic drought led impoverished farmers to rebel against the dictatorship of Bashar al-Assad. The Syrian civil war is steadily engulfing ever greater swaths of the Middle East. American fighter jets are now dropping bombs on Syria in an attempt to contain the chaos.   

*The threat climate change poses to agriculture is particularly daunting. Climate change is already contributing to global food price shocks and will continue to negatively impact the global food supply as warming accelerates. Floods, invasive species, and increasing freshwater scarcity also threaten harvests across the planet.

*Past civilizations have collapsed under the weight of mass agricultural failure. The culprit? Natural climate changes, which unfolded significantly more slowly and gradually than contemporary, man-made climate change.
