    COVID-19 cut pollution in 2020, warming the atmosphere

    Pandemic-related lockdowns briefly warmed the planet. The reason: The cleaner air carried fewer planet-cooling aerosols.

    Explainer: What are aerosols?

    We may not see them, but tiny particles and droplets cloud the air, affecting its properties. Some may be pollutants, others all-natural products.

    Can wildfires cool the climate?

    Severe wildfires are becoming more common. Science is showing that the tiny particles they release into the air can alter Earth’s temperature — sometimes cooling it.

    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.

  8. Plants

    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.

    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.
