Rising Carbon Dioxide Levels Raise Concerns Over Cooling in Earth’s Upper Atmosphere

Rising Carbon Dioxide Levels Raise Concerns Over Cooling in Earth’s Upper Atmosphere

While increasing carbon emissions are heating Earth’s atmosphere near the planet’s surface, higher carbon dioxide levels are cooling the upper atmosphere. Scientists say this phenomenon could impact satellites and the ozone layer, and contribute to weather changes below. A new study published in PNAS adds to the evidence of humanity’s fingerprint on climate change. While […]

    This Is the Make-or-Break Decade for Climate Action, IPCC Warns

    This Is the Make-or-Break Decade for Climate Action, IPCC Warns

    Decisions made this decade will largely determine whether world leaders can limit global warming to 1.5 or two degrees Celsius of warming below pre-industrial levels and avoid the increasingly more drastic impacts of the climate crisis.  That’s one key takeaway from the Intergovernmental Panel on Climate Change’s (IPCC) Synthesis Report of the findings gathered in […]

    Agricultural Emissions to Push World Past 1.5°C of Warming, New Study Warns

    Agricultural Emissions to Push World Past 1.5°C of Warming, New Study Warns

    Food production to meet modern human diets is expected to contribute enough emissions to push global warming past the 1.5°C target, according to a new study. The analysis found that emissions from current global food systems, which are primarily focused on meat, dairy and rice production, could contribute at least 0.7°C of warming by 2100, […]

    More Than 90 Scientists Write Open Letter Encouraging Study of Geoengineering to Cool Planet

    More than 90 scientists from around the world have written an open letter recommending that research be done on the potential of increasing solar radiation modification (SRM) — the reflection of sunlight away from Earth’s atmosphere, sometimes referred to as “solar geoengineering” — in order to slow planetary warming and lessen climate impacts. The scientists […]
