“Human-caused climate change is a global emergency, which disproportionately affects the people who are least responsible for the problem,” writes David Blockstein, PhD, the co-director of Solve Climate by 2030. On April 20, he presented evidence of climate change and offered solutions that can make a difference in a free program titled “Teaching the World about Climate Solutions and Justice.”

“Although a certain amount of climate change is unstoppable,” Blockstein says, “the actions that governments, businesses, universities, and individuals take or do not take this decade will have great impact on how bad climate change will become.” His suggestions: get off fossil fuels (buy electric cars), switch to renewable energy (solar, wind and geothermal), be more efficient in energy use (reduce your carbon footprint), protect wetlands and forests (plant more trees), and vote.
