Some 196 Countries have agreed a new international deal to tackle climate change following marathon United Nations talks in Paris. Delegates approved the historic agreement on Saturday, with the deal aiming to dramatically reduce greenhouse gas emissions, which are responsible for the planet heating up.
The agreement was reached after 13 days of grueling negotiations in a suburb of the French capital. The intention of the summit is to drastically change the way energy is produced and consumed on a global scale, reducing nations' reliance of fossil fuels in favour of clean energy.

According to the Washington Post, French Foreign Minister Laurent Fabius called the agreement an “historical turning point” that could prevent the Earth's seven billion people from the disastrous effects of climate change in the 21st century.
British Prime Minister David Cameron said the universal climate deal agreed in Paris "means that the whole world has signed to play its part in halting climate change", adding: "It's a moment to remember and a huge step forward in helping to secure the future of our planet."
The deal called on the world to collectively cut and then eliminate greenhouse gas pollution but stopped at imposing sanctions on countries that don't. The agreement also aims to keep global temperatures from rising another degree Celsius (1.8 Fahrenheit) between now and 2100, a key demand of poor countries ravaged by rising sea levels and other effects of climate change.
Loud applause erupted in the conference hall after Fabius gaveled the agreement. Some delegates wept and others embraced. The agreement, South African Environment Minister Edna Molewa said, "can map a turning point to a better and safer world."
"It's a victory for all of the planet and for future generations," US Secretary of State John Kerry said, adding that the pact will "prevent the worst most devastating consequences of climate change from ever happening."
Brazilian Environment Minister Izabella Teixeira added: "Today, we've proven that it's possible for every country to come together, hand in hand, to do its part to fight climate change."
In the pact, the countries pledge to limit the amount of greenhouse gases emitted by human activity to the same levels that trees, soil and oceans can absorb naturally, beginning at some point between 2050 and 2100. In practical terms, achieving that goal means the world would have to stop emitting greenhouse gases — most of which come from the burning of oil, coal and gas for energy — altogether in the next half-century, scientists said. That's because the less we pollute, the less pollution nature absorbs.
Achieving such a reduction in emissions would involve a complete transformation of how people get energy, and many activists worry that despite the pledges, countries are not ready to make such profound and costly changes.

The deal now needs to be ratified by individual governments — at least 55 countries representing at least 55 percent of global emissions — before taking effect. It is the first pact to ask all countries to join the fight against global warming, representing a sea change in UN talks that previously required only wealthy nations to reduce their emissions.
The deal commits countries to keeping the rise in global temperatures by the year 2100 compared with pre-industrial times "well below" 2 degrees Celsius (3.6 degrees Fahrenheit), and says they will "endeavor to limit" them even more, to 1.5 degrees Celsius. The world has already warmed by about 1 degree Celsius since pre-industrial times.
Ben Strauss, a sea level researcher at Climate Central, said limiting warming to 1.5 degrees instead of 2 degrees could potentially cut in half the projected 280 million people whose houses will eventually be submerged by rising seas.
More than 180 countries have already presented plans to limit greenhouse gas emissions— a breakthrough in itself after years of stalemate. But those pledges are not enough to achieve the goals in the accord, meaning countries will need to cut much more to meet the goal.
"We've agreed to what we ought to be doing, but no one yet has agreed to go do it," said Dennis Clare, a negotiator for the Federated States of Micronesia. "It's a whole lot of pomp, given the circumstances."
The agreement sets a goal of getting global greenhouse gas emissions to start falling "as soon as possible"; they have been generally rising since the industrial revolution.
It says wealthy nations should continue to provide financial support for poor nations to cope with climate change and encourages other countries to pitch in on a voluntary basis. That reflects Western attempts to expand the donor base to include advanced developing countries such as China.
In a victory for small island nations, the agreement includes a section highlighting the losses they expect to incur from climate-related disasters that it's too late to adapt to. However, a footnote specifies that it "does not involve or provide any basis for any liability or compensation" — a key US demand because it would let the Obama administration sign on to the deal without going through the Republican-led Senate.
The adoption of the agreement was held up for nearly two hours as the United States tried — successfully, in the end — to change the wording on emissions targets. The draft agreement had said developed countries "shall" commit to reducing emissions; in adopting the pact organisers changed the language to say those countries "should" make that commitment.
Experts said the final wording means the deal probably won't need congressional approval.
Nicaragua said it would not support the pact. Its envoy to the talks, Paul Oquist, said the agreement does not go far enough to cut global warming and help poor countries affected by it. Nicaragua is one of 10 participating countries that haven't submitted emissions targets.
Thousands of protesters demonstrated across Paris with a similar message, saying the accord is too weak to save the planet. People held hands beneath the Eiffel Tower and stretched a two-kilometer-long banner from the Arc de Triomphe to the business district La Defense. Police authorised the protest despite a state of emergency declared after the deadly November 13 attacks.
Kumi Naidoo of Greenpeace said the accord is a good start but isn't enough. "Today the human race has joined in a common cause, but it's what happens after this conference that really matters," he said. "This deal alone won't dig us out the hole we're in, but it makes the sides less steep."
The accord does represent a breakthrough in climate negotiations. The UN has been working for more than two decades to persuade governments to work together to reduce the man-made emissions that scientists say are warming the planet. The previous emissions treaty, the 1997 Kyoto Protocol, included only rich countries and the US never signed on. The last climate summit, in Copenhagen in 2009, ended in failure when countries couldn't agree on a binding emissions pact.

The talks were initially scheduled to end Friday but ran over as Western powers, tiny Pacific island nations and everyone in between haggled over wording. The main dispute centered over how to anchor the climate targets in a binding international pact, with China and other major developing countries insisting on different rules for rich and poor nations. The agreement struck a middle ground, removing a strict firewall between rich and poor nations and saying that expectations on countries to take climate action should grow as their capabilities evolve. It does not require them to do so.
Some scientists who had criticised earlier drafts of the pact as unrealistic praised the final language for including language that essentially means the world will have to all but stop polluting with greenhouse gases by 2070 to reach the 2-degree goal, or by 2050 to reach the 1.5-degree goal.
That's because when emissions fall, nature compensates by absorbing less carbon dioxide — and can even release old pollution once there's less of it in the air, said Princeton University's Michael Oppenheimer. Forests, oceans and soil currently absorb about half the world's man-made carbon dioxide emissions.
"It means that in the end, you have to phase out carbon dioxide," said John Schellnhuber, director of the Potsdam Institute for Climate Impact Research in Germany.
In addition to the cuts in emissions, the goal could be reached in part by increasing how much carbon dioxide is sucked out of the air by planting forests or with futuristic technology, said Princeton University's Michael Oppenheimer. But, he added, such technology would be expensive and might not come about.
