As Charles Darwin showed nearly 150 years ago, species can adapt to changing environmental conditions through the trial-and-error process of natural selection. A discouraging new study shows that climate change is happening too fast for evolution to keep up, placing countless plant and animal species at risk.

Think back, if you will, to the halcyon days of 2012, when Donald Trump hadn't yet strangled the US presidency with his small, grubby orange hands. "The concept of global warming was created by and for the Chinese in order to make U.S. manufacturing non-competitive," he tweeted on November 7 of that year.

Scientists recently developed a method to convert sewage into biocrude oil, so it appears that our future will quite literally be shit. According to a report from Pacific Northwest National Laboratory, researchers converted poop to oil using a process called hydrothermal liquefaction. PNNL explains that hydrothermal liquefaction "mimics the geological conditions the Earth uses to create crude oil, using high pressure and temperature to achieve in minutes something that takes Mother Nature millions of years."

On an forbidding shoreline at the bottom of the world, the prodigious ice sheets of West Antarctica dead-end in the Amundsen sea. For decades, scientists have been monitoring this interface of rock, ice and ocean in order to understand how quickly it will retreat as the planet warms up. A new study shows that three of the Amundsen sea's frozen gateways are melting away faster than we realised, raising the spectre of an ice sheet collapse that could trigger a metre of global sea level rise.

Last week, the Paris climate agreement cleared its final hurdle, when the European Union formally signed on. With the support of 73 nations accounting for 57 per cent of global carbon emissions, the deal enters legal force on November 4. So what does that mean, and how soon do we kick our addiction to fossil fuels?

File this under bad news for humanity's climate ambitions: The dams and reservoirs we use to harness 'clean' hydroelectric power and irrigate our crops apparently emit carbon. A lot of it. All told, man-made reservoirs release roughly a gigaton of heat-trapping greenhouse gases each year. That's more than the entire nation of Canada.
