Is climate change real?

Yes. Climate change is real and primarily caused by human activities, especially burning fossil fuels and deforestation.

Key evidence:

•Temperature: Earth has warmed about 1.2°C since the late 1800s; the last decade was the warmest on record.

•Greenhouse gases: CO2 rose from ~280 ppm preindustrial to over 420 ppm today; its isotopic “fingerprint” and falling atmospheric oxygen show it’s from fossil fuels.

•Oceans: Over 90% of excess heat is going into the oceans; marine heatwaves and ocean acidification are increasing.

•Ice and snow: Global glacier mass is declining; Arctic sea ice extent at summer minimum is down ~40% since the 1980s; Greenland/Antarctica are losing ice.

•Sea level: Global sea level has risen about 20–25 cm since 1900, with acceleration in recent decades.

•Extremes and ecosystems: More frequent/intense heatwaves, heavier rainfall, severe droughts and wildfire conditions; shifts in species ranges and earlier springs.

Attribution: Multiple independent lines of evidence show the observed warming pattern matches greenhouse gas forcing, not natural drivers. For example, the stratosphere is cooling while the lower atmosphere warms, nights are warming faster than days, and solar output trends can’t explain recent warming.

Scientific consensus: Assessed by the IPCC and national academies worldwide; recent reviews find >97–99% agreement among publishing climate scientists that humans are the main cause of recent warming.
