For the first time, researchers attempted to measure all the material leaving and entering a mountain range over more than a million years and discovered that erosion caused by glaciation during ice ages can, in the right circumstances, wear down mountains faster than plate tectonics can build them.
Materials in the thin film on the ocean’s surface may affect ice cloud formation and thus climate on a global scale, especially when other known ice-forming particles like mineral dust are scarce or absent.
A period of abrupt climate change 12,000 years ago occurred rapidly in northern latitudes but much more gradually in equatorial regions, report researchers.
One of Canada’s top marine biologists is comparing the harm wrought by the accumulation of plastics in the world’s oceans to the warnings about the pesticide DDT in the famous 1962 book “Silent Spring.”
Researchers for the first time have used seismic sensors to track meltwater flowing through glaciers and into the ocean, an essential step to understanding the future of the world’s largest glaciers as climate changes.
A new study attempts to place a value of goods and services afforded by the ocean, estimating that if the planet’s seas were classified as a country, it would rank as the world’s seventh largest economy.
