El calentamiento global se refiere solo a la temperatura de la superficie de la Tierra, mientras que el cambio climático incluye el calentamiento y los "efectos secundarios" de este calentamiento—como son los glaciares que se derriten, tormentas de lluvia más severas o las sequías más frecuentes. Dicho de otra manera, el calentamiento global es un síntoma del mayor problema del cambio climático causado por los seres humanos.

En realidad, desde diversos puntos de vista, es más difícil pronosticar el tiempo para dentro de dos semanas que pronosticar el clima con décadas de anticipación. 

Meteorologists at NOAA’s National Weather Service have always monitored the conditions of the atmosphere that impact the weather, but over time the equipment they use has changed. As technology advanced, our scientists began to use more efficient equipment to collect and use additional data. These technological advances enable our meteorologists to make better predictions faster than ever before.

A rapidly changing climate brings challenges to our underwater parks in ways we have never seen before. Climate-related impacts, like changing weather patterns and storm events, warming seas, ocean acidification, and sea level rise, are becoming more prevalent around the globe. Changes in climate will affect national marine sanctuaries and the overall health of the ocean, which is vital to our quality of life and, ultimately, our survival.

New research utilizes airborne measurements of carbon dioxide to estimate ocean uptake.

Even though he’s been forecasting since 1887, Punxsutawney Phil’s track record for the entire country isn’t perfect. To determine just how accurate he is, we’ve compared U.S. national temperatures with Phil’s forecasts. On average, Phil has gotten it right 40% of the time over the past 10 years.

NOAA’s Pacific Marine Environmental Laboratory in partnership with the Marine Research Institute in Iceland deployed the first high-latitude ocean acidification monitoring buoy in the Atlantic Ocean in early August. The moored buoy is the first of its kind to be deployed north of the Arctic circle in a region where very little is known about how carbon dioxide (CO2) is entering the ocean environment.

The most ambitious research expedition ever to target the central Arctic got underway as the German icebreaker R/V Polarstern pulled out of Tromso on September 20, 2019, destined for an ice floe where it will serve as a drifting base for hundreds of scientists during the next 13 months.

Volcanic eruptions have had HUGE impacts on the global climate by cooling Earth. It’s only natural to wonder, if the planet is affected by volcanic eruptions, can ENSO be?

Like a prehistoric fly trapped in amber during dinosaurs' days, airborne relics of Earth's earlier climate—including dust, air bubbles, sea salts, volcanic ash, and soot from forest fires—can end up trapped in glacial ice for eons. To climate scientists, those relics tell a story about how our planet's climate and atmosphere have changed over thousands of years.
