Arctic sea ice melt slows dramatically
Arctic sea ice melt slows over 20 years, surprising scientists. Natural variations may be the cause.
Why it matters
- Slowdown in ice melt despite rising emissions.
- Natural variations may balance global heating temporarily.
By the numbers
- No significant decline in sea ice extent since 2005.
- September sea ice area halved since 1979.
- 2.5 sq meters of ice lost per tonne of CO2 emitted since 1979.
The big picture
- Temporary reprieve due to natural ocean current variations.
- Arctic still faces ice-free conditions this century.
What they're saying
- Skepticism about term "dramatic".
- Concerns about misuse by anti-science groups.
Caveats
- Slowdown likely temporary; melting expected to accelerate.
What’s next
- Monitor trends; melting may resume at double rate soon.
