Despite the dramatic changes wrought by climate change, there's still room for optimism, as meteorologist Eric Holthaus writes in his defense of climate change alarmism: "Here's what our message should be: You can make a difference. In fact, you're our best hope."
One easy way to make that difference? Eat less meat. A shift toward vegetarianism - or simply eating less meat from cows, sheep and other farm animals that produce methane - would dramatically cut down on greenhouse gas emissions, as multiple studies have shown. You can also take public transit, unplug your unused gadgets and properly insulate your home to reduce your carbon footprint, too.
