Hidden crisis of liberal democracy creates climate change paralysis

Even as the challenges of climate change grow ever more obvious, what remains largely unacknowledged is the crisis in liberal democratic politics that is preventing an effective response.

An ecomodernist’s manifesto: save wildlife by embracing new tech

With increasing human pressure on the environment, how can we save wildlife while lifting people out of poverty? A new manifesto argues for using technology to intensify energy and agriculture.
Climate change is affecting gender ratios in fish, and could hamper their ability to return to a 50:50 balance.

Climate change can tip the gender balance, but fish can tip it back

Warmer temperatures can throw off the gender balance in some species. But some fish can adjust their offspring’s gender to compensate, but only if temperatures don’t rise too high.

Warmer, wetter, hotter, drier? How to choose between climate futures

Depending on what model you use, climate change could make Sydney a little bit warmer, much hotter, wetter, or drier. Which one should we use? When it comes to planning for climate change, it’s important to look at all the possible futures.

How the US’s post-2020 climate target could fit into a global deal

The United States’ post-2020 climate target raises many questions for this year’s global climate talks, and puts pressure on Australia to raise the stakes.

BP’s extreme climate forecast puts energy giant in a bind

BP’s Energy Outlook report forecast an increase in fossil fuel use by a third. That would make it difficult to keep warming below 2C.

The tropics are getting wetter: the reason could be clumpy storms

For a long time climate models have forecast increasing rainfall in tropics. Now we know part of the reason: clumpy thunderstorms.
