U.S. climate envoy John Kerry is sounding the alarm after scientists reported the Earth logged its four hottest days in recorded human history last week.

John Kerry: “If you listen to the scientists, which not enough people are, the last week they have described as 'terrifying' and as 'uncharted territory.' When you see the risks of what is happening already, with global ice melt, with challenges of fires, of mudslides, of heat, people dying from the level of heat, the quality of air, people are dying around the world — in the millions, by the way. About 8 million people a year die from that.”

In Pakistan, authorities report at least 50 people have been killed in floods and landslides since the start of the monsoon season on June 25. In India, at least 18 people were killed over the weekend as torrential rains swept northern parts of the country.

Here in the United States, a massive, slow-moving storm system brought torrential rains to northeastern states on Sunday, where officials warned flooding could rival 2011’s Hurricane Irene. One person died of drowning in New York’s Hudson Valley, which received up to eight inches of rain.
