Rainfall is probably the most common natural weather event on this planet. But it is not that common when it comes to the ice sheets of Greenland, where temperatures seldom cross the freezing point. But on August 14, 2021, something unprecedented happened. The Summit of Greenland, which is the highest point of its ice sheets, received rain for the first time in recorded history.
IPCC’s* sixth assessment report (AR6) has bad news for the future. The warming beyond 1.5°C or 2°C will be breached much earlier. Average global temperatures will continue to rise and could increase by 5.7 °C by the end of this century compared to 1850–1900.Consequently, the land surface will continue to warm more than the ocean surface. The Arctic will continue to warm more than global surface temperature. Extreme changes become larger with every addition to global warming.
Scientists have discovered viruses nearly 15,000 years old in two ice samples from the Tibetan Plateau. The study conducted by the team from Ohio State University has been published in Journal microbiome. The researchers analyzed ice cores taken in 2015 from the Guliya ice cap in western China. Most of those viruses are unlike any viruses that have been catalogued to date, says the study.
The Arctic is warming three times faster than the global average, says a new report by the Arctic Monitoring and Assessment Programme (AMAP). The report is based on 40 years of observations, between 1979 and 2019. The report says that there has been an increase in extremely high temperatures and a decline in extreme cold events due to climate change.
Hailstorms are common in India during the pre-monsoon season but a rise in their frequency is worrisome.
Researchers say that global warming is a cause of frequent and high-intensity thunderstorms
The sun's heat is the most important factor in the weather patterns around the globe. Warmer ocean temperatures due to human-made activities give storms a bigger battery which not only increases the intensity but also the frequency of hurricanes and cyclones.
On the event of World Environment Day Piu and Pom talk to our planet, Earth!
Archana and her father came out of the Chennai airport into what looked like a scene from an action movie. It was raining, but she could sense when the plane touched down. Now, at the airport, the cars stood honking one behind the other. Sridhar uncle was waiting in the car.
