The damage caused by climate change over this past year was at times so immense it was hard to comprehend. In Pakistan alone, extreme summer flooding killed thousands, displaced millions and caused over $40 billion in losses. Fall floods in Nigeria killed hundreds and displaced over 1 million people. Droughts in Europe, China and the U.S. dried out once-unstoppable rivers and slowed the flows of commerce on major arteries like the Mississippi and the Rhine.
