Researchers have detected novel viruses in samples of glacial ice, suggesting global heating could lead to the re-emergence of historic pathogens. But the science is uncertain.
The next decades, partly as a result of our inaction over the past ones, are crucial to mitigate climate warming. It is time to embrace innovative and proactive new experiments.
The effects of climate change are raising temperatures in the Arctic faster than anywhere else, posing a threat to structures as foundations disintegrate.
It's a vicious cycle: As the weather warms, the Earth's permafrost is melting, releasing greenhouse gases that are going to make the planet even hotter.
