Global warming is a reality, driven by ongoing greenhouse-gas emissions from human activities. Continuing on our current path poses significant risks to livelihoods around the world.
Greenhouse gases (GHGs) driving global temperature rise
Human-induced greenhouse gases
Greenhouse gases (GHGs) trap infrared radiation (heat) in Earth’s atmosphere. These include water vapor, carbon dioxide (CO2), methane (CH4), and several others. More info
The current rate of warming is far too high
Earth’s average temperature has risen by about 1.2 °C since the late 19th century. At an increase of 0.20 °C per decade, the planet could reach dangerous heat levels by 2050. More info
Global warming: dangerous inertia
Among greenhouse-gas emissions, CO2 must be curbed rapidly due to its problematic inertia in warming the planet. More info
Fragile areas at risk from rising temperatures
Global warming could lead to extreme temperatures, particularly after 2050. The resulting heatwaves would pose major risks to vulnerable regions across the tropics. More info
