Pesticide use is driving an “alarming” decline in the world’s insects that could have a “catastrophic” impact on nature’s ecosystems, researchers have warned. More than 40 per cent of insect species are at risk of extinction with decades, with climate change and pollution also to blame, according to a global scientific review. Their numbers are plummeting so precipitously that almost all […]

One of the classic science-fiction treatments of the end of civilisation was The Death of Grass, by John Christopher, in which a mysterious sickness struck down all the grasses on which most of the world’s agriculture is based, from rice to wheat. In the end, politics among the survivors of plague, war and famine was reduced […]

Obesity, climate change, and malnutrition are among the greatest global crises facing our world today. Wouldn’t it be great if there were solutions to tackle all three problems at once? That might sound far-fetched. But a new report, published Sunday in the Lancet, implores us to think about the possibility of big, systemic fixes for these […]
Dramatic increases in the rate at which ice on Greenland and East Antarctica is melting are, along with the heatwave gripping Australia, among the latest manifestations of the changes our planet and its atmosphere are undergoing. Concerns surrounding the risk of melting ice causing sea levels to rise were previously focused mainly on large glaciers. But scientists have discovered […]

For a while now, the scientific community has known that global warming is caused by humanmade emissions in the form of greenhouse gases and global cooling by air pollution in the form of aerosols. However, new research published in Science by Hebrew University of Jerusalem Professor Daniel Rosenfeld shows that the degree to which aerosols cool the […]

Global carbon emissions reached a record high in 2018, rising by an estimated 3.4 percent in the U.S. alone. This trend is making scientists, government officials, and industry leaders more anxious than ever about the future of our planet. As United Nations Secretary General António Guterres said at the opening of the 24th annual U.N. […]

The population of Antarctic krill, the favourite food of many whales, penguins, fish and seals, shifted southward during a recent period of warming in their key habitat, new research shows. Antarctic krill are shrimp-like crustaceans which occur in enormous numbers in the cold Southern Ocean surrounding Antarctica. They have a major role in the food […]

The fall lasts long enough that I have time to watch the blue ice race upward, aeons of time compressed into glacial ice, flashing by in fractions of seconds. I assume I’ve fallen far enough that I’ve pulled my climbing partner, Sean, into the crevasse with me. This is what it’s like to die in […]

Lake Baikal, the world’s oldest, deepest lake, is feeling the temperature of human-induced climate change. Situated in southern Siberia, Baikal occupies one of the fastest warming regions on the planet and, as a result, the lake itself has got warmer, seasonal ice is present for a shorter period of time and has got thinner, and its waters […]
