A new study in the journal Current Biology shows climate change is contributing to changes in flower pigmentation. Clemson University researchers used flower pressings dating back to the 1940s to study how their ultraviolet pigmentation, which is invisible to the human eye but can be captured through UV photography, has changed over time. They found that higher temperatures and ozone depletion correlated with pigment increases and decreases, depending on the species.
This year's historic fire season in the west has made the link between climate change and more intense and frequent wildfires abundantly clear. For firefighter Don Whittemore, it was a close call with a fireball in 2006.
Nearly half of all vehicles sold in the United States are sport utility vehicles, and the International Energy Agency reports they're second-largest contributor to the increase in greenhouse gas emissions in the last decade. But a new wave of electric SUVs and pickup trucks is on the horizon.
Climate change is expected to increase the number of hot, humid days in the Midwest. But will the heat and humidity, which are key components of derechos, translate into more of the destructive windstorms?
