HEALY, ALASKA — Bitter winters still dominate life in the Alaskan interior, but a practiced eye can spot the signs of a warming climate, particularly in the ground. Beneath the rolling fields of tussock scattered just north of the Alaska Range, what was once permanently frozen is starting to thaw. The impacts could ripple across the planet.


In what would be a world first, the government of President Emmanuel Macron wants to phase out all oil and gas exploration and production in France and its overseas territories by 2040. Sounds dramatic, but the EU nation has very little to lose as it sets its sights on a greener future.


Researchers looking at air bubbles trapped in Antarctic ice have found humans are putting more methane into the atmosphere through fossil fuel emissions than previously thought.

Using ice cores from Antarctica's Taylor Glacier, an international team of researchers - including New Zealand and Australian scientists - measured natural rates of methane in the atmosphere over the last 11,000 years. And guess what? The natural levels were much lower than previously estimated. Which means methane emissions from human activities are much greater than expected.

Well, that's just great then, isn't it.


A Harvard study released Tuesday analysed 40 years worth of documents from Exxon Mobil, concluding that the fossil fuel titan has, since 1979, internally acknowledged that carbon emissions are responsible for climate change, even as it has spent thousands over the years publicly denying the global consensus. As internal findings from peer-reviewed research grew more and more conclusive of human-instigated climate change, its public face insisted that climate change research was ambiguous.


Texas Rep. Lamar Smith, the Republican chair of the House Science Committee who also happens to believe global warming might actually be a really good thing, flew off the hook this week. The cause? The New York Times publicised a draft version of a federal scientific report which climate scientists worry Donald Trump's administration is preparing to suppress or doctor.


A devastating heat wave surging through southern Europe has earned the unofficial moniker of "Lucifer," according to several news reports over the weekend. Things over there do seem pretty bad, real bad, bad enough there that the only logical conclusion is Satan danced down there himself, possibly with a fiddle, and played a song which cursed the very winds themselves with the tunes of brimstone and ruin after somebody lost a bet.


Australian-led research has found that even if global warming is kept to only 1.5℃, extreme El Nino events are likely to become twice as common. Under the Paris Agreement, the international community is aiming to limit warming to 2℃, and the researchers warn of the impact that future generations will have to face.

But what do the experts have to say?


Ideas to combat climate change by hacking Earth's climate to make it cooler - "geoengineering" - have been around for decades.

From putting physical barriers in the outer atmosphere to reflect the sun, to using chemicals such as sulphur injected into the atmosphere to mimic the cooling effect of volcanic eruptions - what are the latest theories being floated by scientists?


If there's anything that just about sums up the desperation of the Great Depression in one filthy package, it's photos of the Dust Bowl, when over-farming resulted in roving dust storms choking large swathes of the Great Plains region in the US and Canada. Now, scientists are projecting that climate change could bring those hardscrabble days to a dystopian landscape near you.


You know, in school and in newspapers, the experts warn you about all the dangers of global warming: Melting ice caps, rising sea levels, more destructive hurricanes. All bad stuff! What they don't tell you is that when it gets to be around 50C, the footpath gets so hot, it can fry a puppy paw instantly.


Yikes, is it ever gonna be hot in the western United States this week. The National Weather Service has issued an excessive heat warning for Arizona, Nevada and parts of California, where temperatures are expected to reach as high as 50C. State and local officials are asking people to take the necessary precautions.
