Rebecca also spoke to Gyan Chandra Acharya, who represents a bloc of 48 of the world's poorest countries - including Bangladesh, Bhutan, Haiti and Chad.
This group is one of several saying that limiting temperature rises to 2C is not enough and we must aim for 1.5C.

That 1.5C limit is a very ambitious target, considering the intransigence that often dominates talks such as these.
But there is plenty of vocal support for action, both here in Paris and elsewhere - for example, 3.6 million people signed a petition, delivered today:

How is climate change affecting Pacific islands?
You can put your questions to the BBC's Matthew Price in Vanuatu at 21:00 GMT tonight in a live Q&A on this page.
Here's how you can get in touch:
If you add up the world's present plans to build more coal-fired power stations, it is not good news for climate action - according to an analysis presented here in Paris.
Quote MessageIf you add all of the power plants that are existing today and will still be operating in 2030, you come to 12 gigatonnes from coal fired power in 2030 and that's actually 400% higher than is necessary for 2 degrees.

Queues for food and drink are much shorter on day two at Le Bourget.
This is just as well - because the BBC team is in need of coffee, after a long and busy day covering yesterday's opening.
It comes in recyclable COP21 cups, of course

After a meeting this morning with leaders of small island states, US President Barack Obama vowed to support the needs of islanders who are "among the most vulnerable to climate change".
Referring to his childhood in Hawaii and Indonesia, he said:
Quote MessageI'm an island boy. I understand both the beauty but also the fragility.

Later in the day, Mr Obama said he believed his successor as US President - even if it were to be a Republican - would uphold any commitments made in Paris.
He said Republicans who still oppose an international agreement to reduce carbon emissions are "playing to a narrow constituency" but would feel differently if they won the presidency and felt the pressure of leading a global community.

Leaders from troubled countries surrounding Lake Chad have linked the fate of the lake, along with other dwindling resources in the region, to the prevalence of now regular attacks by the extremist group Boko Haram.
Speaking in a meeting at COP21, they called for more support in the region.
Lake Chad is surrounded by Chad, Cameroon, Niger and Nigeria and has shrunk as much as 90% compared with 1960 - changing the lives of nearby farmers, fishermen and herders. Some also say the increasing desperation is driving people into the extremists' ranks.
Quote MessageThere's a close link between the drying-up of the lake and the terrorism of Boko Haram. We must act quickly, before it's too late.

BBC environment correspondent Matt McGrath filed this short report for Newshour on the BBC World Service.
You can also read Matt's take on the leaders' speeches - and what they mean - here:
Already in small meeting rooms around the vast Le Bourget conference complex, technical negotiations are underway on different parts of the Paris treaty.
A draft of this document already exists, but it is a rather tortuous thing filled with myriad "and/or" options, conditional suggestions and alternative sub-clauses.
The business of hammering these out begins today; teams hope to have a further, shorter draft by the end of the week.
Meanwhile, one of the two huge plenary halls, lead representatives from various countries are setting out the positions of the major country groups.
Meanwhile, another of today's major news stories highlights why that solar power (see previous post) is so important.
Schools and factories have been shut as large sections of northeast China are covered by hazardous smog.
Image source, EPAA report from news agency Reuters this morning said some residents are turning to gallows humour as they deal with persistently toxic air.
A joke circulating among Chinese journalists apparently tells of a reporter approaching an old woman on the street to ask about the impact of the smog.
"The impact is huge," the interviewee replies. "First of all, I'm your uncle."
Some users of China's popular Weibo microblog traced the shapes of famous Beijing landmarks onto near-blank, smog-obscured photographs.
Celia Hatton in Beijing: "The air is so polluted it's darkened the sky"
The world's largest polluter, China has been reluctant to commit to hard targets on carbon emissions - but there are signs that those attitudes are changing.
BBC China editor Carrie Gracie reports on the world's largest solar power farm:
Leaders from indigenous communities who depend on forests attended the same session where Prince Charles was speaking.
The attendees were calling attention to shrinking global forests, from South America to Russia and Africa - forests which play an important role in absorbing carbon dioxide.
Roger Harrabin
BBC environment analyst
Speaking at a session about forestry here in Paris, the Prince of Wales has expressed hope that politicians and businesses are starting to act on the need to protect forests.
He said attitudes were beginning to change - but too many companies still turned a blind eye to their commercial activities destroying forests.
We are testing the world to destruction, he said; we cannot tackle climate change without forests.
And the best strategy, he suggested, is for governments to grant legal title to the indigenous people who inhabit them.
Quote MessageIt's very simple. We must save our forests. We must do all that we can to support the communities that live within forests. For indigenous peoples, this is a question of the proper safeguarding of their reserves, traditions and cultures.

Kiribati President Anote Tong says that any possible climate deal is already too late for his country.
He spoke yesterday to BBC environment correspondent Matt McGrath:
Quote MessageIt's grim whatever we do... There is a real possibility that some of our people will have to be relocated. Already, the process is beginning.
Anote Tong, President, Kiribati
Kiribati President Anote Tong says that any possible climate deal is already too late for his country which is planning migration with ''dignity''.
