    Particles in air help fatten clouds’ water droplets

    Making their own clouds has shown scientists how the fattest water droplets form. Understanding this could lead to better forecasts of climate change.

    Concerns about Earth’s fever

    Burning fossil fuels is causing the planet to heat up, causing weather patterns to change, sea levels to rise and diseases to spread.

    Explainer: How scientists know Earth is warming

    Scientists can calculate global temperatures, both present and past. Their findings show that the planet is rapidly heating up.

    Carbon dioxide levels rise fast and high

    The buildup of carbon dioxide in the atmosphere is rising faster than at any time since dinosaurs roamed the Earth. The burning of fossil fuels is largely to blame.

    Warming’s role in extreme weather

    Extremes in temperature and precipitation will be more common as global temperatures rise. Human-led climate change is largely to blame, a new study finds.

    Arctic warming bolsters summer heat

    Rapid warming in the Arctic is sapping summer storms of their power to cool. That worsens heat waves across the Northern Hemisphere.

    Buildings may be chasing L.A.’s fog away

    Roads and buildings that have mushroomed up around Los Angeles in the past half-century. Now, a study finds they may have created conditions that limit fog. And that could further dry out this very arid part of America’s West Coast.

    Scientists confirm ‘greenhouse’ effect of human’s CO2

    Government scientists link directly, for the first time, a boost in warming at Earth’s surface to increasing levels of carbon dioxide. Much of that gas has been released by human activities, such as coal burning and gas-burning vehicles.

    Fast sea level rise is a very recent change

    Sea levels have been rising for more than a century. But that rise is now speeding up. That suggests that what is driving the rise — climate change — also has increased dramatically in recent years.

    World leaders call for action on climate change

    This week, the presidents of China and the United States pledged to take aggressive action on the release of greenhouse gases to head off dire worldwide climate effects.
