Given the question: I'm taking a test and have to guess the right answer to the question after the article. Article: According to the UN Intergovernmental Panel on Climate Change, global temperatures have risen by approximately 0.6degC in the past century, caused mainly by emissions of greenhouse gases produced by human activities,such as the burning of fossil fuels and deforestation.Temperatures are to increase between 1.6degC and 5.8degC in the next century, accompanied by sea level rise and an increase in the frequency of extreme weather events. The best available evidence suggests that climate changes since the 1970s may already be causing over 150,000 deaths annually, and that greenhouse gas emissions would increase disease burdens in the coming decades.The risks are concentrated in the poorest population, who have contributed least to the problem. The Kyoto Protocol is signed by 128 nations,and commits the participating industrialized countries to cutting emissions of greenhouse gases by over 5% below 1990 level by the period of 20082012. "Over 600 thousand people died in weatherrelated disasters in the 1990s.Temperature and rainfall influence the rates of diseases and infections including malaria,and malnutrition,which together cause over 3.5 million deaths a year.The Kyoto Protocol is the first step towards protecting the climate system,which exerts such a strong influence on our health",said Dr Kerstin Leitner,Assistant DirectorGeneral for Sustainable Development and Healthy Environments. While acting to reduce greenhouse gas emissions, it is also essential to protect vulnerable communities from the effects of climate changes.WHO works to promote measures such as protection from malaria and other climate sensitive diseases, and reliable access to clean water and sanitation, for people in the most vulnerable developing countries.Increasing disease control efforts will also help to protect current and future generations from the impacts of greenhouse gas emissions. Question: What does the passage mainly talk about? Options: A: Climate changes and the effects on human health. B: Climate changes cause over 15,000 deaths annually. C: Who promotes measures such as protection from malaria. D: The Kyoto Protocol helps to protect human health.
The answer is:
A
