Earth’s global surface temperature has increased over the modern instrumental record.
Long-term global measurements show warming, even though individual years and places vary.
Start with a question. Stay for the evidence.
Long-term global measurements show warming, even though individual years and places vary.
Evidence identifies human greenhouse-gas emissions as the main driver of the warming observed since the mid-20th century.
CO₂ interacts with infrared light at particular wavelengths, a property measured in spectroscopy.
Tide gauges and satellite measurements show a long-term rise in global mean sea level.
Weather describes short-term atmospheric conditions. Climate describes their patterns over longer periods.
Renewable does not mean impact-free. Materials, land, construction and disposal belong in the comparison.
Battery production has emissions. Lifetime comparisons also count electricity and driving; typical EVs still come out lower.
Limited weather-modification efforts exist. No demonstrated technology allows people to direct a hurricane toward a chosen community.
