Global temperature increases are being driven by the amplification of the greenhouse effect through human activities, such as fossil fuel combustion, deforestation, and agriculture. Atmospheric CO2 levels exceeded 420 ppm in 2023, a level not seen for millions of years. Data indicates that energy and transport sectors account for approximately 73% of global emissions, while agriculture and livestock contribute roughly 18%.

Regional warming is particularly acute in the Arctic, which is warming at approximately three times the global average rate. According to the American Meteorological Society’s ‘State of the Climate in 2025’ report, both ocean and air temperatures in the Arctic reached their second-highest levels since 1900 in 2025. These shifts have led to record-breaking spring precipitation and biological changes, including the northward expansion of shrubs and trees.

## Timeline

### 2026-08-15: Arctic warming accelerates at three times the global rate

A new climate report shows the Arctic is warming three times faster than the rest of the planet, with 2025 seeing record-high temperatures and significant shifts in precipitation and vegetation.

### 2026-08-09: Climate warming accelerates faster on land than in oceans

Global temperatures are rising, with land surfaces warming nearly twice as fast as oceans due to differences in thermal capacity and the amplification of the greenhouse effect.
