Small islands that bear the brunt of rising sea levels also face the greatest risk of diseases linked to a warmer planet, health leaders said on Saturday, as 13 million medical professionals added to the calls for a global climate pact.

    Hundreds of thousands more people will die every year from heat stroke and tropical illnesses unless negotiators in Paris can agree a strong global deal to decrease global warming the Global Climate and Health Alliance said.

    The Would Health Organization has warned that the effects of extreme weather on the fight against malnutrition, malaria and diarrhea alone will account for an extra 250,000 premature deaths a year by 2030.

    “In the case of small island states like Tuvalu, the health impacts of climate change are palpable,” said the island's health minister.

    “When we are talking about climate change, this is important for the future health of our people, and people everywhere.”

    John Usamate, health minister for Fiji, said the island was suffering from climate-related diseases such as dengue fever and chikungunya, a disease transmitted by mosquitoes and unknown in Fiji.

    “As the climate changes, we are seeing new infectious diseases and many other health impacts,” he said.

    The Global Climate and Health Alliance groups more than 1,700 health organizations and 8,200 hospitals and health facilities.

    It is said it had collected 13 million signatories（签字者） from its members wanting to come to a medical agreement on the need to fight against global warming.

    Even without the wider effects of climate change, air pollution from fossil fuels, especially from coal-fired electricity and vehicle emissions（排放）, is a major cause of early death.

    In the European Union, more than 400,000 early deaths a year are linked to air pollution that cause respiratory disease and some forms of cancer, the European Commission has found.
