Trends & Impacts
Fact
- The average global temperature has increased by at least 1.1°Csince 1880.
- Most of the warming has occurred since 1975, at a rate of roughly 0.15 to 0.20°Cper decade.

Decline in Lake Water Storage
Case in the Caspian Sea
Widespread Decline in Global Lake Water Storage
- Natural lake volumes globally have beendecreasingat a rate of −26.38 ± 1.59 Gt/year.
- 56% of the decline is linked tohuman activities and climate-driven factorslike increased temperatures and evaporation.

The Caspian Sea’s Shrinking Coastline
- The Caspian’s water levels have been dropping since the mid-1990s.
- The decline could continue as climate change bringswarmer air temperatures and increased evaporation.

- At COP29 , global leaders gather to confront the pressing challenges of climate adaptation.
- Azerbaijan, hosting this key event, brings to light the critical issues facing the Caspian Sea region.
Azerbaijan’s Coastal Vulnerability
- Azerbaijan's coastline along the Caspian Sea is increasingly vulnerable.
- Impact on the Caspian Sea for a projected decline of 8–14 m by the end of the 21st century.
