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.
The pressure to pledge for 1.5℃ grew throughout the Paris summit.
The inclusion of a 1.5℃ goal in the Paris climate deal might have surprised some observers. But in reality, the diplomatic groundwork was laid years before.
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.

COP21 ended with an agreement that is at once both historic, important – and inadequate
Job done: COP21 president Laurent Fabius.
At the Paris climate talks, the world has signed up to the first truly global treaty to tackle global warming. Our experts react.
Coal mines are increasingly incompatible with the world’s carbon budget.
The Paris climate agreement doesn't specifically address cutting down on coal, but the tide is turning against coal mining anyway.
Saleemul Huq (left) says the world’s vision should be to help everyone with climate change - even the very poorest.
A majority of countries want visionary action rather than pragmatism at the Paris climate talks, says the International Institute for Environment and Development's Saleemul Huq.
World leaders gathering at COP21 should ditch old ideas about ‘climate equity’.
The sooner nations stop viewing emissions reduction as a burden to be shared, and more as an opportunity to be grasped, the sooner real climate progress will be achieved.
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.
When it comes to gas vs renwables, it seems the balance isn’t right.
Who'd want to take part in the UK energy economy when the government keeps changing the rules?
Malcolm Turnbull, as a former investment banker, should be able to feel the prevailing global winds around climate finance.

After years of squabbling over climate policy, do we now have a prime minister prepared to clean up the mess? Given a fair wind at the Paris summit and an election win, Turnbull might just pull it off.
Ros Kelly was the first in a long line of federal ministers to address themselves to the question of Australia’s emissions target.

When Australia's government first pledged to set an emission-reduction target, Jon Bon Jovi was riding high in the charts. The progress made in the 25 years since has hardly been a blaze of glory.
Global scrutiny has pummelled VW shares.
The market reaction to the VW emissions scandal is just like that of a jilted lover.
In 2010 Malcolm Turnbull threatened to cross the floor to vote for emissions trading. Polls suggest the public would back him now, even if his party won’t.

In backing Abbott's existing climate policy, Malcolm Turnbull looks like appeasing his party. But his prospects would be better served by appealing to voters who are anxious for strong climate action.
Abbott isn’t the first leader to be toppled amid questions over his approach to climate change.

From Hawke-Keating to Rudd-Gillard, climate policy has an uncanny ability to cost Australian political leaders their jobs. And it was a key element in the rivalry between Tony Abbott and Malcolm Turnbull.
Bernie Fraser, Greg Hunt and Clive Palmer announce the Climate Change Authority’s emissions trading review last year, after Palmer prevented the authority being abolished.
The Climate Change Authority, rocked by this week's resignation of its chairman Bernie Fraser but saved last year by the Senate, will continue reviewing climate policy - even if its advice is ignored.
The best way to ensure emissions reductions are permanent is to transform the energy sector.

58 countries have submitted their climate targets ahead of international talks in Paris. We know the numbers, but not all efforts to combat climate change are equal.
Connie Hedegaard says political leaders could stop coming to climate summits unless Paris delivers significant progress.
Connie Hedegaard, who chaired the 2009 Copenhagen climate summit, says the stakes are high for this year's crunch talks in Paris, and that without a solid result, the process could begin to fragment.
Few other world leaders are as enthusiastic as Tony Abbott in endorsing coal as ‘good for humanity’.
Australia's failure to lead on climate action marks a stark shift in political priorities in the past decade. The government is all about immediate economic returns whatever the long-term costs.
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.
