Tropical Cyclone 02A formed about 655 nautical miles south of Masirah Island, Oman. When NASA's Aqua satellite passed over the Arabian Sea, Northern Indian Ocean and captured a visible image of the newly developed storm.   

For decades, scientists have conducted research centered around the five major mass extinctions that have shaped the world we live in. The extinctions date back more than 450 million years with the Late Ordovician Mass Extinction to the deadliest extinction, the Late Permian extinction 250 million years ago that wiped out over 90 percent of species.

Over the years, scientists have figured out the main causes of the mass extinctions, which include massive volcanic eruptions, global warming, asteroid collisions, and acidic oceans as likely culprits. Other factors sure to play a part include methane eruptions and marine anoxic events – when oceans lose life-supporting oxygen.

More Canadian cities will experience damage from the emerald ash borer than previously thought. As a result of climate change and fewer days of extreme cold, the beetle may eat its way further north than originally estimated.

The UK and large parts of northern Europe could become windier if global temperatures reach 1.5˚C above pre-industrial levels, according to a new study.

Many of the European mammals whose habitat is being destroyed by climate change are not able to find new places to live elsewhere.

Current global warming has far-reaching ecological consequences, also for the Earth’s oceans. Many marine organisms are reacting by migrating towards the poles. Researchers at Geozentrum Nordbayern at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have now discovered that marine animals have been migrating for millions of years when the temperature on Earth increases or decreases (https://onlinelibrary.wiley.com/doi/full/10.1111/geb.12732).

New research identifying climate vulnerability hotspots has found that the number of people affected by multiple climate change risks could double if the global temperature rises by 2°C, compared to a rise of 1.5°C.

Two species of seal found in Antarctic seas are helping scientists collect data about the temperature and salinity of waters around vulnerable ice sheets in West Antarctica.

Orangutans, already critically endangered due to habitat loss from logging and large-scale farming, may face another threat in the form of smoke from natural and human-caused fires, a Rutgers University–New Brunswick study finds.

Onward! Our next order of business is to bid adieu to La Niña, as the sea surface temperature in the tropical Pacific returned to neutral conditions in April—that is, within 0.5°C of the long-term average.
