NASA to Launch Spacecraft to Keep Track of Global Carbon Dioxide

June 26, 2014

0 Comments

NASA is about to launch the Orbiting Carbon Observatory – a satellite dedicated to the study of global carbon dioxide sources that will help researchers predict the future of climate change. In the lexicon of climate change, one word appears more often than any other: “carbon.” Carbon credits, carbon emissions, carbon sequestration…. These terms are […]

Computer Simulations Reveal Melting in East Antarctica Yields Unstoppable Sea-Level Rise

May 6, 2014

0 Comments

A new study based on computer simulations reveals that the melting of ice on East Antarctica’s shore could result in an unstoppable sea-level rise. The melting of a rather small ice volume on East Antarctica’s shore could trigger a persistent ice discharge into the ocean, resulting in unstoppable sea-level rise for thousands of years to […]

New research from Yale University shows that parts of ancient Antarctica were as warm as today’s California coast, and polar regions of the southern Pacific Ocean were similar to seawater temperatures near Florida today. Parts of ancient Antarctica were as warm as today’s California coast, and polar regions of the southern Pacific Ocean registered 21st-century […]

Smoke from Wildfires and Forest Emissions Explain Why the Pliocene Was So Hot

February 7, 2014

1 Comment

Using sophisticated Earth system modeling, new research from Yale University reveals that the release of forest emissions and smoke from wildfires 3 million years ago had a far greater impact on global warming than ancient atmospheric levels of carbon dioxide. The research provides evidence that dynamic atmospheric chemistry played an important role in past warm […]

Study Reveals Climate Change is Occurring at an Increased Pace

August 5, 2013

9 Comments

According to scientists at Stanford University, climate change is on pace to occur 10 times faster than any change recorded in past 65 million years. The planet is undergoing one of the largest changes in climate since the dinosaurs went extinct. But what might be even more troubling for humans, plants and animals is the […]

Planetary ‘Runaway Greenhouse’ Climates More Easily Triggered than Previously Thought

July 30, 2013

2 Comments

A newly published study suggests that planetary “runaway greenhouse” climates are more easily triggered than previously thought. It might be easier than previously thought for a planet to overheat into the scorchingly uninhabitable “runaway greenhouse” stage, according to new research by astronomers at the University of Washington and the University of Victoria published July 28 […]

Century-Old HMS Challenger Expedition Data Helps Confirm Ocean Warming

May 29, 2013

0 Comments

A new study using ocean data from the 135 year old HMS Challenger oceanographic expedition combined with modern measurements of ocean temperatures reveals that warming of the planet can be clearly detected since 1873 and that our oceans continue to absorb the great majority of this heat. A new NASA and university analysis of ocean […]

Middle Stone Age Innovation Linked to Rapid Climate Change

May 22, 2013

2 Comments

A newly published study presents the most convincing evidence so far that abrupt climate change was instrumental in the development human evolution. Rapid climate change during the Middle Stone Age, between 80,000 and 40,000 years ago, during the Middle Stone Age, sparked surges in cultural innovation in early modern human populations, according to new research.

Cosmic Impact Sparked Devastating Climate Change, Caused Mass Extinctions

May 21, 2013

2 Comments

A newly published study reveals evidence of a major cosmic event near the end of the Ice Age, detailing how a cosmic impact sparked climate change that caused mass extinctions. Herds of wooly mammoths once shook the earth beneath their feet, sending humans scurrying across the landscape of prehistoric Ohio. But then something much larger […]

New Climate Model Suggests Boreal Forests to Shift North and Relinquish More Carbon Than Expected

May 8, 2013

2 Comments

New climate change research from the Berkeley Lab suggests that boreal forests will likely shift north and will relinquish more trapped carbon than most current climate models predict. It’s difficult to imagine how a degree or two of warming will affect a location. Will it rain less? What will happen to the area’s vegetation? New […]
