Unpredictable nature of Antarctic sea ice levels the focus at conference of meteorology experts in Australia this week

September 26, 2017 — Sea ice levels in Antarctica dropped to a record low this year, but experts say there is not a clear link to climate change. Continue reading Antarctic sea ice levels hit record low, but experts are not sure why

Plastic chunks on Arctic ice show how far pollution has spread

Discovery by UK scientists prompts fear that melting ice will allow more plastic to be released into the central Arctic Ocean – with huge effects on wildlife

September 25, 2017 — A British-led expedition has discovered sizeable chunks of polystyrene lying on remote frozen ice floes in the middle of the Arctic Ocean. Continue reading Plastic chunks on Arctic ice show how far pollution has spread

More errors identified in contrarian climate scientists’ temperature estimates

A new study suggests there are remaining biases in the oft-corrected University of Alabama at Huntsville atmospheric temperature estimates

May 11, 2017 — Human emission of heat-trapping gases is causing the Earth to warm. We’ve known that for many decades. In fact, there are no reputable scientists that dispute this fact. There are, Continue reading More errors identified in contrarian climate scientists’ temperature estimates

Climate change will affect all of us. So why the lack of urgency

From Trump to Brexit, we are all fixated on more immediate news stories. We need to look at the bigger picture

January 19, 2017 — Tomorrow the world shudders as Donald Trump becomes US president. Hopes that wise advisers would mitigate the erratic, half-crazed stream of contradictions pouring from his lips Continue reading Climate change will affect all of us. So why the lack of urgency

Global ‘greening’ has slowed rise of CO2 in the atmosphere, study finds

Increased growth of plants fertilised by higher CO2 levels is only partly offsetting emissions and will not halt dangerous warming, scientists conclude

November 8, 2016 — A global “greening” of the planet has significantly slowed the rise of carbon dioxide in the atmosphere since the start of the century, according to new research.  Continue reading Global ‘greening’ has slowed rise of CO2 in the atmosphere, study finds

Arctic summer sea ice to disappear with 2C warming, study says

A new study, published in Science, pinpoints the direct relationship between carbon emissions and the amount of Arctic sea ice melt they cause as the climate warms

November 3, 2016 — For every tonne of CO2 emitted into the atmosphere, summer sea ice cover in the Arctic shrinks by three square metres, the researchers say.  Continue reading Arctic summer sea ice to disappear with 2C warming, study says

Coral Reefs rapidly ‘wasting away’ under stress

Accelerated acidification of coastal waters has brought about structural decline of only reef in continental US, initially pegged by scientists at around 2050

May 5, 2016 — Florida’s coral reefs are disintegrating far more quickly than previously thought, with warming, acidifying oceans causing a “wasting away” of the coral structures that support an abundance of marine life, new research has found. Continue reading Coral Reefs rapidly ‘wasting away’ under stress

Obama warns of ‘climate refugees’ due to rapid Arctic warming

US Interior Secretary Sally Jewell has painted a stark picture of communities displaced by rising Arctic temperatures that are ‘washing away’ towns

April 31, 2016 — The Obama administration has warned the US will need to deal with a wave of “climate refugees” as the Arctic continues to warm, joining with the Canadian government to express alarm over how climate change is affecting indigenous communities. Continue reading Obama warns of ‘climate refugees’ due to rapid Arctic warming

Record-breaking temperatures ‘have robbed the Arctic of its winter’

Fort Yukon has recorded Alaska’s coldest ever temperatures but this winter temperatures have been much warmer than usual, leading to dangerously thin ice

March 15, 2016 — This year’s record-breaking temperatures have robbed the Arctic of its winter, sending snowmobilers plunging through thin ice into freezing rivers and forcing deliveries of snow to the starting line of Alaska’s legendary Iditarod dogsledding race.

US and Canadian leaders expected to announce a series of common measures including methane emissions cuts and protections for rapidly warming Arctic

March 9, 2016 — Barack Obama and Justin Trudeau will commit to work together to fight climate change and protect an Arctic experiencing the mildest winter ever recorded, sources familiar with the initiatives said.
