Plants emit molecules while growing, reproducing, and defending themselves, and atmospheric chemical reactions turn these compounds into biogenic secondary organic aerosols (SOA). But how do human activities affect biogenic SOA?

Large volcanic eruptions significantly impact climate, so it’s surprising that climate predictions for 1954–2015 appeared less accurate when they used volcanic eruptions to force model simulations.

The Western United States has experienced a winter deluge, following a continuous drought since 2020 and a climate-driven megadrought since the early 2000s. A new webinar examines what might happen next.

Knowing which hazards could harm the things you care about is the first step in protecting them. This portal can help you understand what climate-related hazards you face, now and in the future. ...

There's a 50-60 percent chance of a much warmer than average May in parts of the Pacific Northwest, and a 50-60 percent chance of a much wetter than average May in parts of California.

A digital archive of oral history interviews related to our changing environment, climate, oceans, and coasts. The entire database houses nearly 2300 unique oral histories as part of 118 distinct collections.

Westerly winds over the North Atlantic were farther south than average in winter 2009-10, blowing steadily over the Sargasso Sea.

To better care for our Earth and mitigate the effects of climate change, we must first look to the ocean. This Earth Day, NOAA invite you to learn more about contributions to the global ocean observing system.

The new coral tree will be kept and maintained in a coral nursery off Key Biscayne, to provide a consistent coral supply for experiments conducted at the Experimental Reef Laboratory. A supply of naturally grown corals will greatly enhance the research capabilities of our Coral Program scientists.

An international study finds methane emissions from oil and gas activities over 2010–2019 were 70 percent higher than previously estimated by the US Environmental Protection Agency. But the study also finds the rate of methane emissions fell slightly over that period.
