El Niño is on the prowl in the tropical Pacific. How loud do forecasters think it's going to roar?

Coastal storms brought heavy rains and flooding to the East Coast, and 111 counties had their warmest September on record.

Sharks, seals, birds, and fish count among predator species in the Northeastern Pacific that are ecologically, culturally, and commercially valuable. A new study shows how marine heatwaves affect predators differently.

Sea surface temperatures, storms, greenhouse gases, aerosols, and natural radiation all affect the tropical Atlantic climate. A new study finds that a north-to-south ocean temperature gradient is a key driver of Atlantic hurricanes and Sahel rainfall.

The ocean is storing 91% of the excess heat from global warming, contributing to sea level rise, ice shelf retreat, and stress on marine life. ...

NOAA and partner scientists recently completed two successful field tests in the US Arctic merging new technologies and traditional ship surveys of phytoplankton species distributions in response to surface warming.

Summary: CDC’s Climate and Health Program helps states, cities, territories, and tribes protect human health from a changing climate. CDC provides data, tools, and technical guidance to help U.S. health agencies reduce vulnerability and increase resilience to the health effects of climate change.

El Niño communicates with North America by tweaking the jet stream. How does all that work?

Of all the potential impacts of global warming, increases in extreme heat are the most certain. Yet it's the one extreme U.S. communities have paid the least attention to so far. Ladd Keith hopes to change that.

Extreme heat has implications for power grid infrastructure, food production and nutrition, childhood education, worker health and safety, and crime.
