The concentration of carbon dioxide emissions in the atmosphere reached an unprecedented level this month. Researchers at the fossil fuel giant Exxon saw it coming decades ago.

I’m no expert on Australian politics – I don’t know all the cross-currents that will determine this week’s balloting. But I do know a fair amount about the climate crisis, having written the first book on the subject back in 1989. So I can say with confidence that if Australians want to play a serious role in fixing the greatest challenge we’ve ever faced, this may be about the last election where people retain enough leverage to make a real difference.

It’s a foregone conclusion that as long as the world keeps emitting carbon dioxide, we’ll keep setting records for how much ends up in the atmosphere. But that doesn’t make the recent high water mark of carbon dioxide any easier to swallow.

On Sunday night’s episode of Last Week Tonight, John Oliver joined the growing chorus of voices pointing out that we aren’t doing enough to save our planet. Oliver sounded the alarm in light of a new report on climate change from the United Nations that warns that lasting change is coming to the planet as soon as 2040. “That’s just 21 years from now,” Oliver pointed out. “By that point, Finn Wolfhard will only be 37, Ariana Grande will only be 46, and Lou Dobbs will only be dead for 30 years.”

Netflix recently released a new nature documentary series, Our Planet, and its bland title is only the first indication that it is attempting to compete with the BBC’s popular Planet Earth and Blue Planet series. As with those shows, it too has soothing narration by David Attenborough, and it likewise involves the editing down of unimaginable hours of nature footage into narratives neat enough for humans to consume.

Climate change is transforming life by redrawing coastlines, turning vast areas of forest into infernos, stirring enormous storms and spreading exotic diseases. An indirect casualty of this upheaval could be Joe Biden’s hopes of becoming US president. Biden, frontrunner in the polls to secure the Democratic nomination, has not laid out a plan to address the crisis.

UN Secretary-General Antonio Guterres said Sunday that the political will to fight climate change seems to be fading at the same time as things are getting worse for those feeling the effects. Guterres made the comments after arriving in Auckland, where he spoke to reporters alongside Prime Minister Jacinda Ardern. Guterres plans to spend three days in New Zealand as part of a trip to the South Pacific to highlight the problems of climate change.

A glacier that once moved 20 meters (65.6 feet) per year is now moving that fast every day, according to a post on a NASA-run U.S. government website. And, some estimate it could be racing even more quickly. NASA's Earth Observatory claims a cold-based glacier in the Russian High Arctic has been sliding "at a breakneck pace" since 2013 -- a phenomenon the space agency says "mystified" University of Colorado Boulder glaciologist Michael Willis.

Sen. Bernie Sanders will speak at a Green New Deal rally at Howard University on Monday that also features Rep. Alexandria Ocasio-Cortez, organizers said. The event, organized by the Sunrise Movement, gives the 2020 contender a high-profile platform to court the environmental left. Sanders' planned appearance comes as Democratic candidates are starting to spar over their climate plans and recent polls show environmental issues taking on...

Delays in tackling climate change could cost companies about $1.2 trillion worldwide during the next 15 years, according to the United Nations. That’s the preliminary analysis of a UN Environment Finance Initiative project that brought together 20 global fund managers to measure the impact of climate change on 30,000 of the largest listed companies. The group has created a guide for investors to assess how their holdings would respond to different levels of global warming and policy making.

The sale of new petrol and diesel fuelled cars will be banned on the Isle of Man by 2040, the Chief Minister has said. Howard Quayle said a new Climate Change Bill would be brought forward "before the end of the next legislative year". The proposed laws would also impose a ban on the use of gas and oil boilers in new houses by 2025. The Isle of Man Green Party's chairman Andrew Bentley said the pledge was a "good step in the right direction".

Plenty of people and companies have had a hand in leading the globe down the destructive, possibly irreversible path to climate catastrophe. In his New York Times Best Seller “Falter: Has the Human Game Begun to Play Itself Out?,” Bill McKibben, who has written over a dozen books about the environment and has been called “the world’s best green journalist,” fingers the Koch brothers, the Republican Party and fossil fuel companies worldwide, among countless others.

Climate change has already increased the spread and severity of a fatal disease caused by Ranavirus that infects common frogs (Rana temporaria) in the UK, according to research led by ZSL's Institute of Zoology, UCL and Queen Mary University of London published today in Global Change Biology.

Entire communities might need to be moved away from coasts and rivers as the UK takes urgent action to prepare for an average global temperature rise of 4C, the Environment Agency warned. The agency said on Thursday that difficult decisions would have to be taken in the coming years to make sure the UK was resilient amid flooding that would not be held back by higher land defences.

A fungal plant disease from Asia has been spreading across banana-growing areas of Latin America and the Caribbean since the 1960s. New research suggests that climate change is aiding the spread of this highly destructive plant infection.

34 years on from the original concert, Queen guitarist Brian May wants to see another Live Aid event to raise awareness for climate change. Back in July of 1985, the world of music changed forever. Inspired by the plight of those affected by the Ethiopian famine, Bob Geldof put in a few calls to begin organising the now-iconic Live Aid concerts.

One million animal and plant species are at imminent risk of extinction due to humankind’s relentless pursuit of economic growth, scientists said on Monday in a landmark report on the devastating impact of modern civilization on the natural world.

When future generations look back on the global-warming scare of the past 30 years, nothing will shock them more than the extent to which the official temperature records – on which the entire panic ultimately rested – were systematically “adjusted” to show the Earth as having warmed much more than the actual data justified.

The world’s leading scientists will warn the planet’s life-support systems are approaching a danger zone for humanity when they release the results of the most comprehensive study of life on Earth ever undertaken. Up to 1m species are at risk of annihilation, many within decades, according to a leaked draft of the global assessment report, which has been compiled over three years by the UN’s leading research body on nature.

The Democratic-controlled House approved a bill Thursday that would prevent President Donald Trump from fulfilling his pledge to withdraw the United States from the landmark Paris climate agreement and ensure the U.S. honors its commitments under the global accord. The bill falls far short of the ambitious Green New Deal pushed by many Democrats, but it is the first significant climate legislation approved by the House in nearly a decade. The measure was approved, 231-190, and now goes to the Republican-run Senate, where it is unlikely to move forward. Trump has said he will veto the legislation if it reaches his desk.
