Global Warming

Canada has already gotten less extreme cold, longer growing seasons, shorter snow and ice cover seasons, earlier spring peak streamflow, thinning glaciers, thawing permafrost, and rising sea level. The annual average temperature in Canada has increased at roughly twice the global mean rate. Patterns are different across regions of the…

Cultivated meat – whereby meat is produced from animal cells using a combination of biotechnology, tissue engineering, molecular biology and synthetic processes – is thought to be a more environmentally sustainable alternative to conventional meat production. Indeed, much food is considered more environmentally sustainable than intensively produced meat, such as…

In the month of June, when winter bites in the southern hemisphere and the sea around the Antarctic freezes over, right whales swim north. Many of them gather in the bay outside the town of Hermanus in South Africa. Here, the warmer South African water is perfect for mating or…

The Greenland ice shelf is melting and causing a huge pool of cold water to form in the North Atlantic, Met Éireann chief forecaster Evelyn Cusack has said. Evidence of the pool has emerged over the last five years and the pooling may have an impact on the future weather…

ISLAMABAD: Federal Minister for Climate Change and Environmental Coordination Senator Sherry Rehman on Wednesday called the global community to activate the global loss and damage fund to enhance climate resilience of the vulnerable countries facing direct impacts of global warming and environmental degradation. Addressing the third breakout session titled “A…

The theory that water-breathing animals such as fish will shrink due to global warming has been called into question by a study published today in eLife. The study found that warm water pollution increased growth rates but also death rates, resulting in a population of younger, but larger fish. The…

Microbes play important roles in ecosystems, and these roles are changing with global warming. Scientists also now know that most types of microbes are infected by viruses, but they know relatively little about how these viral infections could change how microbes react to warming. In this study, scientists describe many…

(Image credit: Shutterstock)Global warming has trapped an explosive amount of energy in Earth's atmosphere in the past half century — the equivalent of about 25 billion atomic bombs, a new study finds. In the paper, published April 17 in the journal Earth…
