Read MoreModi: Energy is 'basic human need'published at 18:24
India's Prime Minister, Narendra Modi, remained forthright about his country's need to develop:
Quote MessageDemocratic India must grow rapidly, to meet the aspirations of 1.25 billion people - 300 million of whom are without access to energy. We are determined to do so.
He also outlined "ambitious targets" to reduce emissions and switch to renewable energy - commitments that India has indicated, in its submission to COP21, will cost $2.5 trillion.
Mr Modi also said the lion's share of climate action should come from wealthy, developed countries.
Quote MessageIt is not just a question of historical responsibility. They also have the most room to make the cuts and have the largest impact.
Narendra Modi, Prime Minister of India

Mr Modi has been blaming the developed countries for failing to effectively tackle climate change. But according to a report published by WHO in 2014, 13 Indian cities are among the top 20 most polluted cities in the world with the capital, New Delhi, topping the list. What has Mr Modi done to tackle that?
Cameron: What will we tell our grandchildren?published at 17:58
David Cameron, Prime Minister of the UK, told the summit that instead of making excuses to future generations, "we should be taking action today".
He said that private finance has been under-utilised in tackling climate change:
Quote MessageHow could we argue to our grandchildren that it was too difficult... when in London alone there's five trillion dollars of funds under management?

The delegates need to concentrate on renewables and alternatives to internal combustion engines and jet engines and produce a framework around these rather than talk vaguely about percentages reduction of CO2 which are difficult to verify.
Juncker calls for binding deal; Modi calls for solar investmentpublished at 17:33
Jean-Claude Juncker, president of the European Commission, joined those calling for a climate agreement with some legal teeth.
Quote MessagePromises will no longer be enough; we need a binding, robust and lasting agreement
Jean-Claude Juncker, President, European Commission
One of the biggest stumbling blocks to that goal is likely to be the US, where a binding deal is very unlikely to be passed by the Senate.
President Obama did not mention the possibility in his speech; this tweet emphasises the responsibility of the private sector.

End of twitter post 2A long day continuespublished at 17:12
Based on their starting time, the leaders' speeches are running more than one hour behind schedule - however, organisers were not foolhardy enough to set a finishing time for this afternoon's sessions.
People are making use of the lounges in the press centre here at Le Bourget - though surprisingly few, so far, are sleeping.
We will continue our coverage on this page at least until we hear from British PM David Cameron, who is currently scheduled to speak within the next hour.

On the UN climate change website it states:
"Think before you travel. If a video conference call will suffice, spare the hassle and expense, and CO2 emissions." Yet these same people are going to create tens of thousands of tons of emissions gathering in Paris to discus how to reduce, you guessed it, emissions. Worldwide in 2014 aviation created 705 million tons of emissions. Reducing current schedules by half would therefore save 352 million tons. More than any "carbon tax" will attain.

Regardless of whether you are a developed or developing nation we must end our reliance on coal now. Even if you are one of the few still unconvinced by anthropogenic climate change, the health impacts of coal generation on humans and wildlife are undeniable. These health and environmental costs do not feature in the power price - we need to make these costs more transparent to facilitate an informed debate on how we should balance our energy mix.

Enele Sopoaga, the prime minister of Tuvalu, spoke with passion from his perspective as the leader of a small Pacific island state.
Quote MessageLike other nations in the Pacific, our survival depends on the decisions we take here in Paris. We stand on a cliff edge. Either we stand united and agree to combat climate change, or we all stumble and fall.
Image source, UNFCCQuote MessageIf we save Tuvalu, we will surely save the world.
Enele Sopoaga, Prime Minister of Tuvalu
Mr Sopoaga also called for a "permanent mechanism... anchored in the Paris treaty" to pay for damage caused by climate change - referred to as "loss and damage" in these negotiations.
He said Tuvalu, despite making a tiny contribution to global emissions, had made its own INDC, external commitment to reduce them.

Heads of state agree there is a climate problem and someone should do something.
But they are dependent on successful economies, not just for industry but for taxation that gets invested into healthcare and infrastructure.
Which of the elected representatives will sacrifice economic success at home, and reputation, to contribute to global need?

James Masters from Salisbury (12:27) said: "It's cars that are contributing most to global warming".
I disagree. Impact from cars is dwarfed by the greenhouse gas contribution of livestock. Methane and carbon dioxide from the livestock industry adds more than every plane, train, lorry and car on Earth. Yet the livestock population continues to soar, to feed nearly nine billion people - more meat, more heat!

The countries that are better placed and have the necessary technology to adopt renewable resources must take the first step. These countries have been reluctant to do so and are just passing the buck. This has been the trend that must break!
Putin and Obama share half-hour 'sit-down'published at 15:11
On the sidelines of the ongoing talks, Barack Obama has met Vladimir Putin.
They discussed tensions in Turkey and the conflict in Syria, according to a spokesman for the Russian president.
Image source, APDmitry Peskov said the two leaders both spoke in favour of a political settlement to Syria's civil war, AP reports.
Russia and the US are both involved in a new diplomatic effort in Vienna to bring about a ceasefire, potentially within weeks. According to the White House, Mr Obama told Mr Putin that Syrian President Bashar Assad must leave power as part of that transition, a long-held US position that remains at odds with Russia's support for Mr Assad.
Mr Obama also called on Russia to focus its airstrikes in Syria on Islamic State militants, not rebels fighting Mr Assad, the White House said.
