Global average temperatures could pass 1.5°C above pre-industrial levels within the next decade, new projections suggest

May 8, 2017 — The timing of when we actually hit the 1.5°C threshold will depend heavily on a natural cycle in the Pacific Ocean, the study finds, which can either dampen or accelerate global temperature rise. Continue reading Pacific Ocean shift could see 1.5C limit breached within a decade

A new study shows how a switch in a major climate system could accelerate global temperatures to a 1.5°C limit, but some scientists are challenging the assumptions

May 8, 2017 — In the Brazilian city of São Paulo, more than 80 experts, including dozens of climate scientists, gathered back in March for a giant planning meeting. Continue reading Planet could breach 1.5C warming limit within 10 years, but be aware of caveats

Scientists have long been searching for an explanation for the contrasting fortunes of sea ice at the Earth’s poles. While the Arctic has seen a rapid decline in sea ice extent in recent decades, the seas around Antarctica have slowly gained ice.

July 7, 2016 — Now, a new study suggests a natural shift from one state to another in the Pacific Ocean is responsible for the increase in Antarctic sea ice.  Continue reading Pacific Ocean behind recent Antarctic sea ice growth
