Countries such as Mauritania have contributed little to climate change, yet face the worst impacts such as crop failure.
The countries that have contributed the least to climate change will experience the worst of its effects.
Renewable energy is at the more expensive end of the emissions cost curve, but is a vital piece of the bigger picture.

Australia's greenhouse emissions are once again rising, after a decade of consistent declines. But the right policies are already in place to turn things around - they just need to be ramped up.
It’s a tall order - especially when it’s spelled out on the Eiffel Tower.
How will the world actually deliver on the Paris climate ambition to hold global warming to no more than 1.5℃? It's a tough scientific and technical challenge.
Laurent Fabius has brought the gavel down on a successful deal.
The Paris deal has laid the foundations for real global progress on climate change. On that score, it must be judged a huge success.
Aided by expanded farming in Asia, there’s been a global increase in greenhouse gases from farming.
The Paris climate summit yielded a pact to reduce air pollutants that contribute to global warming but missed a chance to address the interlinked effects of agriculture and climate.
There's a huge gap between what India claims it can do, and what it's actually doing to bring down emissions.
The world’s soils store four times more carbon than its plants.
A new bid to boost the amount of carbon stored in the world's soils has been launched at the Paris climate summit.

The greenhouse gases that cause climate change will take centre stage at the upcoming Paris climate talks. What are they and what are their effects?
New technique captures 78% carbon using molten tin.
Gas is the solution to some but not all our problems.
UK's decision to close coal power plants is really a statement of the obvious, and does nothing to answer the problem of what to do afterwards.
Australia can balance energy, water and food needs with the environment.

We have all the tools to achieve economic growth and environmental sustainability - we just have to choose to use them.

Using more accurate data, researchers find that waste disposal at methane-emitting landfills is two times greater than previous EPA estimates.
Conventional wisdom says Barack Obama will hit political obstacles on the way to fulfilling his climate ambitions. But they might be easier to sidestep than you think,
Much has been made of the domestic political roadblocks between US President Barack Obama and climate action. But by using existing treaties he can get around the hostile Congress and help cut global emissions.
Australia’s foreign minister Julie Bishop at the last year’s Lima climate talks, where nations agreed new transparency rules over climate targets.
Countries that drag their feet on climate action have fewer places to hide these days. Rules brought in at the 2014 Lima talks require them not just to set targets, but to publicly justify them too.
US President Barack Obama has unveiled the United States' most comprehensive climate policy so far.
US President Barack Obama's new climate plan aims to cut greenhouse emissions from the nation's coal-dominated power sector by 32% by 2030. Will it get through, and how will it affect this year's climate talks?
Replanting forests is one way to remove carbon dioxide from the atmosphere. This is a site in China.
New research shows that we'll have to remove carbon from the atmosphere for any chance of keeping warming below 2C.
It might be nice if buying the right to emit greenhouse pollution could be made a bit simpler.
The term 'carbon tax' is a political poison in Australia, thanks to the previous carbon tax which was actually an emissions trading scheme. Yet ironically, many economists prefer a tax over an ETS anyway.
Tasmanian hydro power had a boom couple of years when the carbon price was in place.
A year after the demise of the carbon tax, we might expect both coal and greenhouse emissions to have bounced back, at the expense of renewables like hydroelectricity. Sure enough, that's what happened.
To get to zero emissions, we’ll have to reform our energy sector away from fossil fuels.
To avoid dangerous climate change there is a finite amount of greenhouse gas emissions, in particular CO<sub>2</sub>, that we can add to the atmosphere - our global carbon budget. If we use our budget wisely, we have until about 2050 to transition to zero net emissions. But how do we get there?
Worldwide, the livestock industry is a bigger source of greenhouse gases than transport.

The recent Lancet Commission report rightly pointed out that climate change is a huge risk to global public health. But it shied away from one of the main issues: the world consumes far too much meat.
