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 […]

Satellite Data Reveals a Shift in Vegetation Growth at Northern Latitudes

March 11, 2013

1 Comment

In a newly published study, scientists examined the relationship between changes in surface temperature and vegetation growth, finding that temperature and vegetation growth at northern latitudes now resemble those found at 4 degrees to 6 degrees of latitude farther south as recently as 1982. Vegetation growth at Earth’s northern latitudes increasingly resembles lusher latitudes to […]

Shedding Light on the Role of Forests in Carbon Sequestration

January 29, 2013

1 Comment

Researchers at Berkeley Lab have developed an analytical method that combines satellite images, simulation modeling and fieldwork to help detect forest mortality patterns and trends, helping scientists understanding of the role of forests in carbon sequestration and the impact of climate change. The Earth’s forests perform a well-known service to the planet, absorbing a great […]

Personal Experience of Climate Change May Influence Opinion of It

January 24, 2013

1 Comment

A study from scientists at Yale University examined the extent to which 91,000 individuals in 89 countries on five continents detected recent changes in average local temperatures, finding that public opinion of climate change may shift in response to the personal experience of climate change. Human beings around the world are observing and accurately detecting […]
