If currently implemented policies are continued with no increase in ambition, there is a 90% chance that the Earth will warm between 2.3°C and 4.5°C, with a best estimate of 3.5°C.

Anthropogenic emissions drive global-scale warming yet the temperature increase relative to pre-industrial levels is uncertain. Using 300 years of ocean mixed-layer temperature records preserved in sclerosponge carbonate skeletons, we demonstrate that industrial-era warming began in the mid-1860s, more than 80 years earlier than instrumental sea surface temperature records. The Sr/Ca palaeothermometer was calibrated against ‘modern’ (post-1963) highly correlated (R2 = 0.91) instrumental records of global sea surface temperatures, with the pre-industrial defined by nearly constant (<±0.1 °C) temperatures from 1700 to the early 1860s. Increasing ocean and land-air temperatures overlap until the late twentieth century, when the land began warming at nearly twice the rate of the surface oceans. Hotter land temperatures, together with the earlier onset of industrial-era warming, indicate that global warming was already 1.7 ± 0.1 °C above pre-industrial levels by 2020. Our result is 0.5 °C higher than IPCC estim

Catastrophic climate change and the collapse of human societies By Josep Peñuelas, Sandra Nogué National Science Review, Volume 10, Issue 6, June 2023 The scientific community has focused the agend…

Is It Hot Enough Yet for Politicians to Take Real Action? The latest record temperatures are driving, again precisely as scientists have predicted, a cascading series of disasters around the world.…

CUNNAMULLA, Australia — Carol Godfrey gazed out her helicopter cockpit at the miles of mulgas glowing green and gold in the dawn light. For decades, the bushy trees had been little more than a last resort for farmers needing to feed their cattle in the arid Outback. But recently, the humble mulgas have become a hot commodity. It’s not the hardwoods themselves that are valuable, however. It’s what they store: carbon.

Disputé au milieu de l’été en Australie, le premier Majeur de la saison a pris des mesures il y a quelques années.

A climate protester who blocked a lane of traffic on Sydney Harbour Bridge has been sentenced to 15 months in prison with a non-parole period of eight months, with human rights advocates labelling the punishment “disproportionate”.

Fossil fuels, fisheries and farming: the world’s most destructive industries are protected – and subsidised – by governments

If 15 planned coal mining projects in Australia enter operation they would boost the country’s methane emissions from the dirtiest fossil fuel by nearly a fifth, according to an analysis from energy think tank Ember.

An Australian court has blocked a proposal for a huge coal mine, saying the emissions produced by the fuel would threaten human rights. The Galilee Coal Project would add 1.58 billion tons of carbon dioxide to the atmosphere over its lifespan — more than triple Australia’s annual domestic emissions — and impact the human rights of future generations, the Queensland Land Court ruled on Friday.

With the Australian Actuaries Institute Climate Index reaching the highest rainfall and temperature levels since the index was launched in 2018, it is not surprising that the Actuaries Institute’s latest Green Paper has warned of climate change’s impact on home insurance affordability in Australia.

If our next federal government wants to save the reef, it must tackle the main reason it is in trouble by phasing out fossil fuel use and exports as quickly as possible. Otherwise it’s like putting bandaids on an arterial wound.

The Black Summer forest fires of 2019–2020 burned more than 24 million hectares, directly causing 33 deaths and almost 450 more from smoke inhalation. But were these fires unprecedented? You might remember sceptics questioning the idea that the Black Summer fires really were worse than conflagrations like the 1939 Black Friday fires in Victoria.

The Australian Bureau of Meteorology has declared a La Niña weather event is under way, with modelling predicting it “will persist until the late southern hemisphere summer or early autumn 2022”.

The findings of the Intergovernmental Panel on Climate Change suggest Australia may have to jettison tracts of the bush unless there is a massive investment in climate-change adaptation and planning.

A group of leading international researchers have issued a stark new warning to governments that relying on technology alone will not be enough to address the growing climate emergency, saying that presumptions that economic growth can continue unchecked should be challenged.

Environment minister has 28 days to appeal historic ruling that carbon emissions from coalmine should not cause young people ‘personal injury or death’

At the tail end of winter in 2015, the ground in the Wimmera in northwestern Victoria had been a little dry but conditions weren't too bad for farmers. The crop season was going well.

the court found that one million of today’s Australian children are expected to be hospitalised because of a heat-stress episode, that substantial economic loss will be experienced, and that the Great Barrier Reef and most of Australia’s eucalypt forest won’t exist when they grow up. It found this harm is real, catastrophic, and – importantly from a legal perspective – “reasonably foreseeable”.
