Yes, Climate Change Is Real

This is one of the most well-established findings in modern science, supported by multiple independent lines of evidence:

Key Evidence

•Temperature records: Global average temperatures have risen about 1.1°C (2°F) since pre-industrial times, based on thousands of measurement stations worldwide

•Ice cores: Show current CO2 levels are higher than any point in at least 800,000 years

•Sea level rise: Oceans have risen roughly 8-9 inches since 1880, with the rate accelerating

•Glacial retreat: Documented shrinking of glaciers and ice sheets globally through satellite imagery and direct observation

•Ocean acidification: Measurable changes in ocean chemistry from absorbed CO2

Scientific Consensus

•Multiple independent scientific organizations worldwide (NASA, NOAA, national academies of science from dozens of countries) agree on the basic findings

•The vast majority (97%+) of actively publishing climate scientists agree that recent warming is primarily human-caused

•This conclusion comes from thousands of peer-reviewed studies using different methods that converge on similar findings

What's Debated

While the existence of warming and human contribution to it are well-established, there's legitimate scientific discussion about:

•Precise regional impacts and timing

•Best policy responses

•Specific climate model predictions for certain variables

•Economic tradeoffs of different mitigation strategies
