The work has taken on urgency as global temperatures rise, heat waves become more frequent and intense, and casualties mount.

It is important to remember that, when it comes to pesticide levels in produce, 'legal' does not mean safe. Federal food tolerance residue levels often allow for higher exposure levels than public health advocates, including EWG, consider to be safe.

Healthy sleep habits are associated with a lower risk of heart failure. Adults with the healthiest sleep patterns (morning risers, sleeping 7-8 hours a day and no frequent insomnia, snoring or excessive daytime sleepiness) experienced a 42% reduction in the risk of heart failure compared to those with unhealthy sleep patterns.

Volcanoes rank among the most destructive and awe-inspiring phenomena on the planet. But these fiery fissures do much more than just destroy. They also create.

The busiest hurricane season ever recorded is continuing on into the late fall, with consequences so horrifying one can hardly stand to look.

There’s a whole slew of reasons to not rely on blocking the sun to cool the planet. But a new paper puts up perhaps the best one yet: It might not work if we continue to let carbon emissions skyrocket.

A package of fuel efficiency measures agreed at the International Maritime Organization is expected to shave just 1% off shipping emissions this decade.
