Sentences with phrase «atmospheric gases supporting»

«This new understanding about how life can still exist in physically extreme and nutrient - starved environments like Antarctica opens up the possibility of atmospheric gases supporting life on other planets,» adds Ferrari.

Not exact matches

The technique potentially could be used in several ways to support research on atmospheric greenhouse gases.

That such a lake can even exist lends empirical support to a seemingly blue - sky proposal: Inject excess atmospheric CO2 deep into the ocean, where the high pressure would trap the gas in a liquid form.

There are no experimental data to support the hypothesis that increases in human hydrocarbon use or in atmospheric carbon dioxide and other green house gases are causing or can be expected to cause unfavorable changes in global temperatures, weather, or landscape.

This evidence includes multiple finger - print and attribution studies, strong correlations between fossil fuel use and increases in atmospheric greenhouse gas concentrations, carbon isotope evidence that is supports that elevated carbon dioxide concentrations in the atmosphere are from fossil sources, and model predictions that best fit actual observed greenhouse gas concentrations that support human activities as the source of atmospheric concentrations.

Industry, with the full support of the administration, continues the fait accompli of radically expanded natural gas fracking across the country, with serious unresolved issues about fugitive atmospheric methane emissions and the potential for contamination of drinking water aquifers — and with no adequate federal regulatory structure in place.

And this all supports the analysis that the climate is much more sensitive to changes in greenhouse gas emissions and other «forcings» than the IPCC models have been saying and that a doubling of atmospheric concentrations of carbon dioxide from preindustrial levels to 550 ppm will ultimately warm the planet far more than 3 °C, as NASA's James Hansen argues (see «Long - term» climate sensitivity of 6 °C for doubled CO2).

For some time, the EU (supported by other parties) had been pushing for the adoption of «global pathways» that were in line with the International Panel on Climate Change (IPCC) findings: these included ensuring that global atmospheric greenhouse gas (GHG) concentrations stayed below 450 ppm (parts per million) and that we do not allow for a temperature increase above 2 degrees.

Excerpt: Essentially the site exists to promote global warming alarm - ism and attack anyone who does not agree with their declaration of doomsday (proven of course by their own computer climate models) and the need for government intervention against the life supporting, atmospheric trace gas, carbon dioxide.

CO2 is a «well mixed» gas in the atmosphere despite all the sources and sinks, despite the 180 ppm reading in the ice cores being too low to support C3 plants, despite the daily and seasonal sawtooth Also see former EPA scientist — slide 24: «Most of the atmospheric carbon dioxide is being transported by water droplets.»
