In the first study of its kind, scientists found a correlation between climate change and a rise in urban rat populations.

Climate change is contributing to a global rise in urban rat infestations, according to a new Science Advances study. As temperatures increase, rats are better able to thrive -- even in inclement weather that would typically deter the population's growth, the article explained.

A new study of cities across the globe has found a link between climate change and larger increases in the urban rat population.

More rats: that’s the latest indignity that climate change is dumping on major cities around the world, including in Canada’s largest city, according to a new study from a group of global rodent and public health scientists.

A new study is the first to link rising temperatures with booming rat populations in cities around the world. Rising seas, intensifying droughts, worsening floods — these are well-known effects of climate change, the consequences of pumping too much heat-trapping pollution into the air.

We are on our heels and being pushed backward,” Jonathan Richardson, the study’s lead author and an ecologist at the University of Richmond, said about the fight against rat infestations. There’s more bad news: The study found a strong link between an increase in rats and rising temperatures,

Based on individual trends within cities, Washington was by far the leader in rat increases, followed by San Francisco, Toronto, New York City and Amsterdam.

There’s a saying that in a big city you are never more than six feet away from a rat. It’s an urban myth but scientists are warning that cities across the US and beyond are becoming far rattier, and t

Winters are getting warmer and shorter as the climate changes. That's helping rat populations grow in several U.S. cities.

Global warming is worsening droughts, making sea levels rise, and fueling deadly storms. Now scientists have a new problem to add to that list: Climate change is helping rat populations thrive in U.S.

Climate change is fueling a surge in rat populations across major US cities, with Washington, DC, seeing the worst increase over the past two decades, a new study said.The study published by Science Advances on Friday,

Urban rat populations have surged dramatically in recent years, with some cities experiencing increases of nearly 400%, according to a new study.
