    Surprising long-haul dust and tar are melting high glaciers

    Dust and tar blown onto high mountains, like the Himalayas, boost the melting of snow and ice far more than scientists had realized. Here’s why.

    Explainer: What is an algorithm?

    These step-by-step instructions underlie social media, internet searches and other computer-based activities. But what are they exactly? We explain.

    The faster trees grow, the younger they die

    As climate change spurs forest tree growth, it also shortens trees’ lives. That results in a quicker release of climate-warming carbon back into the atmosphere.

  4. Deadly heat: Expected by century’s end, it’s here already

    Instances of hot and humid conditions that threaten human lives are on the rise.

    Fossil fuels appear to release far more methane than we thought

    Ice cores reveal less methane than expected. This suggests today’s fossil fuel industry is responsible for nearly all of the methane emissions from natural sources today.

    CO2 emissions have nosedived as COVID-19 keeps people home

    The COVID-19 pandemic restricted travel that can pollute the air. By April, travel-related daily emissions of greenhouse gases was back to 2006 levels.

    A rainforest once grew near the South Pole

    A forest flourished within 1,000 kilometers of the South Pole. That was a while ago, as in millions of years ago.

    Climate change drove Australian wildfires to extremes

    Australia’s devastating 2019–2020 wildfires were at least 30 percent more likely because of human-caused climate change.

    How to curb the climate heating by contrails

    Contrails are narrow clouds left behind in the sky by jets. They add to climate change. But a new study suggests a way to curb their contribution.

    Explainer: CO2 and other greenhouse gases

    Carbon dioxide is just one of several chemicals that contribute to the greenhouse effect. Nitrous oxide, methane and CFCs are other big contributors.

    Analyze This: Climate change could make food less healthy

    Levels of important nutrients are lower in crops exposed to high levels of carbon dioxide, a greenhouse gas. How high? Try levels expected to be typical 30 years from now.
