Home of polar bears, seals and walruses could be mostly water for months as early as 2035 due to fossil fuel emissions

The Arctic could have summer days with practically no sea ice within the next decade due to emissions from burning fossil fuels, a study has found.

This would transform the unique habitat, home to polar bears, seals and walruses, from a “white Arctic” to a “blue Arctic” during the summer months, scientists said. The calculation used for “ice free” means less than 1m sq km, in which case the Arctic would be mostly water.

The findings, published in the journal Nature Reviews Earth ­­& Environment, suggest the first ice-free day in the Arctic could occur more than 10 years earlier than previous projections.

The authors said consistently ice-free Septembers could be expected by 2035 to 2067. The exact year within that period is dependent on how quickly the world reduces the amount of fossil fuels burned.

‘Missing half the equation’: scientists criticise Australia over approach to fossil fuels

Prof Lesley Hughes and others says there is ‘cognitive dissonance’ between Labor’s stated commitment to the climate crisis and its policies

The Australian government is “missing half the equation” in acting on the climate crisis by backing a shift to renewable energy but having no plan to get out of fossil fuels, according to an author of a new scientific review.

Prof Lesley Hughes is a leading climate change scientist and member of the independent Climate Council and government advisory body the Climate Change Authority. Hughes said there is a “cognitive dissonance” between Labor’s stated commitment to addressing the problem and the pace at which it is moving.

The dissonance is most clear in it subsidising or approving new and expanded fossil fuel developments while arguing it supports trying to limit global heating to 1.5C – a goal agreed at UN climate conferences.

“The two things are completely at odds with each other,” she said.

Hughes is the co-author of a Climate Council review, released on Wednesday, which found Australia should be cutting national carbon dioxide emissions by 75% by 2030. The government’s legislated target is a minimum 43% cut (compared with 2005 levels).

The report said the country should be aiming to reach net zero emissions by 2035 – much sooner than the current 2050 goal. The finding is broadly consistent with other analyses that have found Australia should be moving more rapidly.
