Is climate change real?

Yes. The climate is warming and the primary cause is human activities, especially the burning of fossil fuels and deforestation.

Key evidence:

•Global temperatures have risen by about 1.1–1.3°C since the late 1800s; recent years are the hottest on record.

•Atmospheric CO2 is ~420 ppm (up from ~280 ppm preindustrial), with a fossil-fuel isotope signature and well-understood heat-trapping physics.

•Oceans are absorbing most of the excess heat; sea level has risen about 20–25 cm since 1900 and is accelerating.

•Glaciers and the Greenland/Antarctic ice sheets are losing mass; Arctic sea ice is declining.

•Heatwaves and heavy rainfall events are becoming more frequent and intense; wildfire and drought risks are increasing.

This conclusion is supported by independent measurements worldwide and by major scientific bodies (e.g., IPCC, NASA, NOAA, WMO, national academies).
