As giant swarms of locusts spread across East Africa, the Arabian Peninsula and the Middle East, devouring crops that feed millions of people, some scientists say global warming is contributing to proliferation of the destructive insects. The largest locust swarms in more than 50 years have left subsistence farmers helpless to protect their fields and will spread misery throughout the region, said Robert Cheke, a biologist with the University of Greenwich Natural Resources Institute, who has helped lead international efforts to control insect pests in Africa. “I’m concerned about the scale of devastation and the effect on human livelihoods,” Cheke said, adding that he also worried about “the impending famines.”e change

At The Times, more than 360 journalists have been publishing a torrent of stories about the pandemic, roughly 100 a day. You can reach them all through here. And, as I mentioned last week, our coronavirus coverage is open to everyone without a subscription.
Lessons from coronavirus and climate change: Don’t be deceived by small numbers
The flu has a death rate of around 0.1 percent in the U.S. COVID-19 has put an estimated death rate between 1 and 3.4 percent, although we won’t know the true death rate until the outbreak is over. The difference between 0.1 percent and 2 percent may not sound like much. Indeed, some people on social media have opined that a 97 or 98 percent survival rate sounds pretty good to them.

At 1.5 degrees C of warming, heat waves will affect 14 percent of the world’s population once every five years. At 2 degrees C, 37 percent of the world will be exposed to heat waves — 420 million more people. At 2 degrees C of warming, 61 million people more will be exposed to severe drought than if we kept warming to 1.5 degrees C. That half a degree could expose between 180 and 270 million more people to be exposed to water scarcity.
As the human onslaught against life on Earth accelerates, no part of the biosphere is left pristine. The simple act of consuming more than we actually need drives the world’s governments and corporations to endlessly destroy more and more of the Earth to extract the resources necessary to satisfy our insatiable desires. In fact, an initiative of the World Economic Forum has just reported that ‘For the first time in history, more than 100 billion tonnes of materials are entering the global economy every year’ – see ‘The Circularity Gap Report 2020’ – which means that, on average, every person on Earth uses more than 13 tonnes of materials each year extracted from the Earth.
COVID-19 Rekindles Discussion on Climate Change, Infectious Disease – The Energy Mix
“We don’t know with COVID, what role if any the climate effects that we’re already seeing in species around the world may have had on the risk of this disease emerging,” he stresses. But a warming climate has already triggered “this extraordinary migration to the poles”, as species scramble to escape the heat. “That has led to the spread of pathogens, because animals that carry pathogens came in contact with other animals that didn’t carry those pathogens, and there was transmission.”
So “the bottom line here is that if you wanted to prevent the spread of pathogens, the emergence of pathogens, as we see not just with people and COVID, but as well with wildlife, you wouldn’t transform the climate. Because that forces species to come into contact with other species that may be vulnerable to infections. There are lots of forces, and habitat loss is a major contributor to it.”
