About
The scientific consensus is unequivocal: Earth's climate is warming rapidly due to human emissions of greenhouse gases (CO₂, methane, nitrous oxide) from fossil fuels, deforestation, and agriculture. Global average temperature has already risen 1.1–1.2°C above pre-industrial levels; at current trajectories, 2–3°C of warming by 2100 is projected.
Consequences already visible include more frequent and intense extreme weather (hurricanes, droughts, floods), sea level rise, Arctic ice loss, species migration and extinction, and ocean acidification. The Paris Agreement (2015) committed nations to limiting warming to 1.5°C — a target increasingly difficult to meet. 97% of climate scientists agree on the human cause; the scientific question is no longer 'is it happening' but 'how bad will it get.'
