Is climate change real?
Yes. Climate change is real and primarily caused by human activities—mainly the buildup of heat‑trapping gases like carbon dioxide from burning fossil fuels and deforestation.
Why scientists are confident:
•Physics: Greenhouse gases trap infrared heat; more of them means a warmer planet.
•Measurements: Global air and ocean temperatures have risen by over 1°C since the late 1800s; oceans are storing more heat; sea levels are rising; glaciers and Arctic sea ice are shrinking.
•Patterns: Increases in extreme heat, heavy rainfall, and wildfire weather match what models have long predicted for a warming world.
•Consensus: Major scientific bodies worldwide (e.g., the IPCC, U.S. NASA/NOAA, national academies) independently conclude the warming is real and largely human‑caused.
