Arctic exploration provides window on future climate change

Climate model projections show that the Arctic Ocean will be completely ice-free by the summer by 2060. However, the record lows in sea ice extent of 2007 and 2012 demonstrated that these projections were too optimistic and ...

Seafloor research expedition features live online video feed

UC Santa Cruz hydrogeologist Andrew Fisher is leading an expedition on the research vessel (R/V) Atlantis this summer to explore fluid flow and microbial habitats deep within the ocean crust. His team is returning to a set ...

Improved interpretation of volcanic traces in ice

How severely have volcanoes contaminated the atmosphere with sulfur particles in past millennia? To answer this question, scientists use ice cores, among others, as climate archives. But the results differ, particularly in ...

Limiting global warming is not enough

So far, international climate targets have been restricted to limiting the increase in temperature. But if we are to stop the rising sea levels, ocean acidification and the loss of production from agriculture, CO2 emissions ...
