Past global warming similar to today's: Size, duration were like modern climate shift, but in two pulses
The rate at which carbon emissions warmed Earth's climate almost 56 million years ago resembles modern, human-caused global warming much more than previously believed, but involved two pulses of carbon to ...
Climate change caused by ocean, not just atmosphere, study finds
Most of the concerns about climate change have focused on the amount of greenhouse gases that have been released into the atmosphere.
Beyond LEDs: Brighter, new energy-saving flat panel lights based on carbon nanotubes
Even as the 2014 Nobel Prize in Physics has enshrined light emitting diodes (LEDs) as the single most significant and disruptive energy-efficient lighting solution of today, scientists around the world continue ...
Research confirms how global warming links to carbon emissions
Research by the University of Liverpool has identified, for the first time, how global warming is related to the amount of carbon emitted.
Why is Venus so horrible?
Venus sucks. Seriously, it's the worst. The global temperature is as hot as an oven, the atmospheric pressure is 90 times Earth, and it rains sulfuric acid. Every part of the surface of Venus would kill you ...
Students aim to put cyanobacteria on Mars to generate oxygen
Mars is a very harsh and hostile environment for future human explorers and like any other known planet it has no breathable air. That could change someday, and it may be soon enough for our generation to ...
Traces of possible Martian biological activity inside a meteorite
Did Mars ever have life? Does it still? A meteorite from Mars has reignited the old debate. An international team that includes scientists from EPFL has published a paper in the scientific journal Meteoritics ...
Recently discovered microbe is key player in climate change
As permafrost soils thaw under the influence of global warming, communities of soil microbes act as potent amplifiers of global climate change, an international study has shown.
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 ...
Rotating nanotube motors offer glimpse of future nanodevices
Scientists use 'smallest possible diamonds' to form ultra-thin nanothreads
(Phys.org) —For the first time, scientists have discovered how to produce ultra-thin "diamond nanothreads" that promise extraordinary properties, including strength and stiffness greater than that of today's ...
What would happen to the climate if we stopped emitting greenhouse gases today?
Earth's climate is changing rapidly. We know this from billions of observations, documented in thousands of journal papers and texts and summarized every few years by the United Nations' Intergovernmental Panel on Climate Change. The primary cause of that change is the release of carbon d ...
Artificial Photosynthesis: Creating fuel from sunlight
Researchers have made significant progress towards developing a process of Artificial Photosynthesis (AP) that could replace the use of fossil fuels in the future.
Climate deal: What the scientists say
A snapshot of what scientists are saying about climate change ahead of the next round of UN talks opening in Lima on Monday.
