Global Climate Influenced By Variations In Ice Sheet Height
2014-11-05 03:58:08

In a study published today in PNAS, Dr William Roberts of Bristol's School of Geographical Sciences and colleagues use computer models to simulate a Heinrich event in Hudson Bay, Canada, adjusting the models to consider freshwater influx only, changing ice sheet height only or both factors together.

Scientists have long been concerned that global warming may push Earth's climate system across a "tipping point," where rapid melting of ice and further warming may become irreversible -- a hotly debated scenario with an unclear picture of what this point of no return may look like.

Two studies show that the movement rate of plates carrying the Earth's crust may not be constant over time.

Using sediments from a remote lake, researchers from Brown University have assembled a 60,000-year record of rainfall in central Indonesia. The analysis reveals important new details about the climate history of a region that wields a substantial influence on the global climate as a whole.

The role of the hydrological cycle during abrupt temperature changes is of prime importance for the actual impact of climate change on the continents.

Early Warning System Needed In A World With Changing Climates

The National Research Council says that even gradual climate change can have abrupt impacts in human infrastructure and ecosystems if critical thresholds are crossed, so an early warning system needs to be developed.

Earthworm Poop Could Help Improve Climate Change Models

A recent discovery about earthworm excrement could help scientists improve our models of future climate change.

Lake Elgygytgyn

An international team of scientists, led by Julie Brigham-Grette of the University of Amherst, has analyzed the longest continental sediment core ever collected in the Arctic to provide “absolutely new knowledge” of Arctic climate from 2.2 million to 3.6 million years ago.

Researchers Uncover Genetic Payload Of Ancient Plankton In Black Sea Sediments
2013-05-07 10:23:32

Sorting through the vast amounts of genetic data from the Black Sea sediment record, Woods Hole Oceanographic Institution (WHOI) marine paleoecologist Marco Coolen was astounded by the variety of past plankton species that left behind their genetic makeup.

Antarctic Ecosystem Caused Rapid Evolution 041913
