First direct observation of carbon dioxide's increasing greenhouse effect
Scientists have observed an increase in carbon dioxide's greenhouse effect at the Earth's surface for the first time. The researchers, led by scientists from the US Department of Energy's Lawrence Berkeley ...
Evidence from warm past confirms recent IPCC estimates of climate sensitivity
New evidence showing the level of atmospheric CO2 millions of years ago supports recent climate change predications from the Intergovernmental Panel on Climate Change (IPCC).
Who will pick up the bill? Possible job cuts and revenue loss as a result of ocean acidification
Ocean acidification, a direct result of increased CO2 emission, is set to change the Earth's marine ecosystems forever and may have a direct impact on our economy, resulting in substantial revenue declines and job losses.
Transforming hydrogen into liquid fuel using atmospheric CO2
Swiss scientists have completed their solution for transforming hydrogen gas into a less flammable liquid fuel that can be safely stored and transported. Another possible application of their technology would ...
Mankind using Earth's resources at alarming rate
Humanity would need five Earths to produce the resources needed if everyone lived as profligately as Americans, according to a report issued Tuesday.
How Earth avoided global warming, last time around
Geochemists have calculated a huge rise in atmospheric CO2 was only avoided by the formation of a vast mountain range in the middle of the ancient supercontinent, Pangea. This work is being presented to the ...
Warming climates intensify greenhouse gas given out by oceans
Rising global temperatures could increase the amount of carbon dioxide naturally released by the world's oceans, fuelling further climate change, a study suggests.
Climate chief warns of 'urgency' as CO2 levels rise
The UN's climate chief called for urgency Monday as she opened a new round of global talks amid warnings that Earth-warming carbon dioxide levels were approaching a symbolic threshold never seen in human ...
New study shows three abrupt pulse of carbon dioxide during last deglaciation
A new study shows that the rise of atmospheric carbon dioxide that contributed to the end of the last ice age more than 10,000 years ago did not occur gradually, but was characterized by three "pulses" in ...
Past climate change and continental ice melt linked to varying CO2 levels
Scientists at the Universities of Southampton and Cardiff have discovered that a globally warm period in Earth's geological past featured highly variable levels of CO2.
Atmospheric carbon levels nearing historic threshold
(Phys.org) —For the first time in human history, concentrations of the greenhouse gas carbon dioxide (CO2) could rise above 400 parts per million (ppm) for sustained lengths of time throughout much of the Northern Hemisphere ...
The last ice age
A team of scientists has discovered that a giant 'burp' of carbon dioxide (CO2) from the North Pacific Ocean helped trigger the end of last ice age, around 17,000 years ago.
How hot did Earth get in the past? Scientists uncover new information
The question seems simple enough: What happens to the Earth's temperature when atmospheric carbon dioxide levels increase? The answer is elusive. However, clues are hidden in the fossil record. A new study ...
Ancient forests stabilized Earth's CO2 and climate
UK researchers have identified a biological mechanism that could explain how the Earth's atmospheric carbon dioxide and climate were stabilised over the past 24 million years. When CO2 levels became too low fo ...
