A new research led by MPhil student Miss Yu Yan Yau and supervised by Dr Benoit Thibodeau from the Department of Earth Sciences and the Swire Institute of Marine Science, the University of Hong Kong (HKU), highlighted the importance of reducing fossil fuel combustion not only to curb the trend of global warming, but also to improve the quality of China’s coastal waters. 

As global warming intensifies, the ice melting of polar ice sheet may release much more bioavailable Fe to the ocean and atmosphere.

How do the impacts of Covid-19 and climate change differ?

There is no longer a need to guess what ocean temperatures were like in the remote tropical Pacific hundreds of years ago. The ancient coral that lived there know all.

If circulation of deep waters in the Atlantic stops or slows due to climate change, it could cause cooling in northern North America and Europe – a scenario that has occurred during past cold glacial periods.

When hikers returned to UC Davis Stebbins Cold Canyon Reserve in 2016, a year after a wildfire swept through its expanse of oak trees and chaparral in Northern California, half of them expected to see a devastated landscape. 

Denman Glacier in East Antarctica retreated 3.4 miles (5.4 kilometers) from 1996 to 2018, according to a new study by scientists at NASA's Jet Propulsion Laboratory and the University of California, Irvine.

The shrinking of this once-vast inland lake means winds more frequently pick up dust from the exposed lakebed.

Arctic sea ice extent—the area where ice concentration is at least 15 percent—reached its apparent annual maximum on March 5, 2020.

A global analysis of over 300 marine species spanning more than 100 years, shows that mammals, plankton, fish, plants and seabirds have been changing in abundance as our climate warms.
