Climate Summary

A study has found that air passengers are exposed to extremely high levels of ultrafine particle pollution, particularly during boarding and taxiing, with levels far exceeding those defined as high by the World Health Organization.

Research indicates that polar bears in southern Greenland exhibit genetic changes that may enable them to adapt to global warming conditions, providing a glimmer of hope for this vulnerable species. Meanwhile, Alaska faces significant environmental challenges as the proposed Ambler Access Road, which would unlock mineral deposits for green energy, threatens local ecosystems and the livelihoods of Indigenous communities dependent on fish and caribou.

In the Pacific Northwest, residents are currently facing catastrophic flood threats due to days of heavy rainfall, highlighting the increasing severity of extreme weather events linked to climate change.

Furthermore, a recent study reveals that Africa's rainforests, which historically have been critical for carbon removal, are now producing carbon instead, raising concerns about their role in global climate dynamics.
