Climate change is making weather more extreme around the world. Some places are experiencing unusually severe drought, while historically fierce storms batter other places. Mountains of evidence now clearly show that the climate change we are experiencing today is driven by increased carbon dioxide in the atmosphere. Everything we can do to reduce carbon dioxide, including transitioning to clean renewable fuels in place of fossil fuels, will give us better chances of someday dampening the extremes of too much water or not enough that plague so many places today.
