The Latest: Stern: GOP aim to repeal CO2 rules won't prevail

United States climate negotiator Todd Stern has told representatives of other countries that they don't need to worry about Republican efforts to repeal regulations to reduce carbon dioxide pollution from power plants.

In his first press briefing of the climate talks, Stern followed other officials' script, emphasizing how world leaders meeting in Paris on Monday provided momentum for negotiations.

In a press briefing at Paris climate talks, WHO officials emphasized the deadliness of climate change by re-releasing a study they published last year that said if carbon dioxide emissions continue to rise the number of global warming related deaths would jump from about 150,000 now to nearly a quarter of a million.

WHO public health director Maria Neira said in the past there were only a few mentions of human health in climate deals, but this year's negotiations seems to have more discussions about preventing climate related deaths.

An Indian delegate at U.N. climate talks says India will be able cut back on its carbon emissions if money is made available to boost renewable energy in an envisioned climate agreement in Paris.

In Senegal, rising sea levels and rising salt levels in farmland are making it harder to produce fruit, vegetables and poultry for traditional lemon chicken.

The head of the World Food Program is warning that hunger linked to climate change may worsen mass migrations, and is hoping for an ambitious international accord to slow global warming.

Cousin says the U.N. food agency cannot fulfill its promises to eradicate hunger without a global climate accord, and investment in preventive measures such as drought-resistant seeds and water-conserving agriculture.

Man-made global warming is causing worsening droughts and floods that are threatening traditional food sources, she said — especially in the poorest countries, where hunger is already a top problem.
