Racking Up Climate Milestones One President at a Time

Racking Up Climate Milestones One President at a Time

A happy Presidents Day to you. There have been 44 presidents spanning nearly 240 years of U.S. history.

Hearing about climate change may bring heat waves and sweltering summers to mind, but in most regions in the U.S., winter temperatures are also on the rise.

In the future, this combination of urbanization and climate change could raise urban temperatures to levels that threaten human health, strain energy resources, and compromise economic productivity. Summers in the U.S. have been … Read More

87 Cities, 4 Scenarios and 1 Really Hot Future

Global temperatures are rising, but nothing brings global warming home to people like a really hot summer day — those few days a year when it actually feels like the planet is boiling over. But what if those rare sweltering days, over 90° or 100°F, were not so rare and began to dominate summers? That could happen if carbon emissions continue … Read More
