It's a message no one wants to hear: To slow down global warming, we'll either have to put the brakes on economic growth or transform the way the world's economies work. That's the implication of an innovative University of Michigan study examining the evolution of atmospheric CO2, the most likely cause of global climate change. The study, conducted by José Tapia Granados and Edward Ionides of U-M and Óscar Carpintero of the University of Valladolid in Spain,...

A University of Colorado Boulder-led team has developed a new monitoring system to analyze and compare emissions from man-made fossil fuels and trace gases in the atmosphere, a technique that likely could be used to monitor the effectiveness of measures regulating greenhouse gases. The research team looked at atmospheric gas measurements taken every two weeks from aircraft over a six-year period over the northeast United States to collect samples of CO2 and other environmentally important...

Why did the atmosphere contain so little carbon dioxide (CO2) during the last Ice Age 20,000 years ago? Why did it rise when the Earth's climate became warmer? Processes in the ocean are responsible for this, says a new study based on newly developed isotope measurements. This study has now been published in the scientific journal "Science" by scientists from the Universities of Bern and Grenoble and the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association....

CO2 Emissions Could Prevent Next Ice Age

Increases in carbon dioxide emissions will prevent us from experiencing the next Ice Age, which experts believe would have occurred within the next millennium, according to research published in this week's edition of the journal Nature Geoscience. An international team of scientists examined variations in the Earth's orbit, as well as global weather and climate patterns, determining that the next worldwide deep-freeze should begin within the next 1,500 years, the Telegraph reported on...

Unprecedented levels of greenhouse gases in the Earth's atmosphere are disrupting normal patterns of glaciation, according to a study co-authored by a University of Florida researcher and published online Jan. 8 in Nature Geoscience. The Earth's current warm period that began about 11,000 years ago should give way to another ice age within about 1,500 years, according to accepted astronomical models. However, current levels of carbon dioxide are trapping too much heat in the atmosphere to...

A drastic decrease in atmospheric carbon dioxide levels appears to have been the catalyst that led to the formation of the Antarctic ice sheet, according to a new study published December 1 in the journal Science. The research, which was completed by an international team of experts led by Mark Pagani of Yale University, "helps solve a long-standing scientific puzzle and confirms the power of CO2 to dramatically alter global climate," according to a Thursday press release from the...

Atmospheric carbon dioxide (CO2) is one of the most important greenhouse gases and the increase of its abundance in the atmosphere by fossil fuel burning is the main cause of future global warming. In past times, during the transition between an ice age and a warm period, atmospheric CO2 concentrations changed by some 100 parts per million (ppm) — from an ice age value of 180 ppm to about 280 ppm during warm periods. Scientists can reconstruct these changes in the atmospheric carbon...

Researchers recommend the reworking of global carbon models in Nature The global uptake of carbon by land plants may be up to 45 per cent more than previously thought. This is the conclusion of an international team of scientists, based on the variability of heavy oxygen atoms in the carbon dioxide of the atmosphere driven by the El Niño effect. As the oxygen atoms in carbon dioxide were converted faster than expected during the El Niño years, current...

There have been instances in Earth history when average temperatures have changed rapidly, as much as 10 degrees Celsius (18 degrees Fahrenheit) over a few decades, and some have speculated the same could happen again as the atmosphere becomes overloaded with carbon dioxide. New research lends support to evidence from numerous recent studies that suggest abrupt climate change appears to be the result of alterations in ocean circulation uniquely associated with ice ages. "There might be other...

The present rate of greenhouse carbon dioxide emissions through fossil fuel burning is higher than that associated with an ancient episode of severe global warming, according to new research. The findings are published online this week by the journal Nature Geoscience. Around 55.9 million years ago, the Earth experienced a period of intense global warming known as the Palaeocene"“Eocene Thermal Maximum (PETM), which lasted for around 170,000 years. During its main phase, average annual...


Word of the Day
attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
