Scientists Warn of Emergency on Global Scale
In a “State of the Planet” declaration issued after a four-day conference, leading scientists said Earth was now facing unprecedented challenges, from water stress, pollution and species loss to spiralling demands for food.
Managing the Risks of Extreme Events and Disasters to Advance Climate Change Adaptation, IPCC
Climate change is amplifying risks from drought, floods, storms and rising seas, threatening all countries, and nations should prepare, an international panel of climate scientists warned in a report issued Wednesday. The report pointed in particular at coastal megacities.
A decade of weather extremes
The ostensibly large number of recent extreme weather events has triggered intensive discussions, both in- and outside the scientific community, on whether they are related to global warming.
Amount of Coldest Antarctic Water Near Ocean Floor Decreasing for Decades
Oceanographers find that, the coldest deep ocean water, Antarctic Bottom Water, has been disappearing at an average rate of about eight million metric tons per second over the past few decades, equivalent to about fifty times the average flow of the Mississippi River. The world’s deep ocean currents play a critical role in transporting heat and carbon around the planet, thus regulating our climate.
Climate Change Damage to Oceans to Cost $2 Trillion
Greenhouse gases are likely to result in annual costs of nearly $2 trillion in damage to the oceans by 2100, according to a new Swedish study, by the Stockholm Environment Institute.
Scientists Look Far to the North to Explain Young Whale in San Francisco Bay
Recent sightings of a gray whale and her infant calf swimming near Alcatraz and Sausalito in San Francisco Bay illuminated a likely repercussion of melting polar ice, scientists said.
Ancient Sea-Level Rise and Projections for Future Increase
The seas are creeping higher as the planet warms, but scientists have not yet reached a consensus about how high they may go. Projections for the year 2100 range from inches to several feet, or more.
Asia and Pacific: climate disasters displace 42 million
Climate-related disasters have displaced more than 42 million people in Asia over the past two years. The environment is becoming a significant driver of migration in Asia and the Pacific as the population grows in vulnerable areas, such as low-lying coastal zones and eroding river bank.
Rising Sea Levels Seen as Threat to Coastal U.S.
About 3.7 million Americans live within a few feet of high tide and risk being hit by more frequent coastal flooding in coming decades because of the sea level rise caused by global warming, according to new research.
