Sentences with phrase «atmospheric carbon dioxide from fossil fuels»

Based on documents and other evidence from an eight month investigation, ICN described how Exxon scientists were warning of potentially catastrophic effects of a buildup of atmospheric carbon dioxide from fossil fuels as early as 1977.

Not exact matches

The event commemorates the 5 November 1965 President's Council of Advisors on Science and Technology (PCAST) report to President Lyndon B. Johnson, which warned that the accumulation of atmospheric carbon dioxide from the burning of fossil fuels would «almost certainly cause significant changes» to the environment.

Human - caused climate change caused the storm to drop significantly more rain than storms would have before atmospheric carbon dioxide levels spiked from the consumption of fossil fuels, according to research published yesterday.

«Today atmospheric carbon dioxide emissions from burning fossil fuels are implicated in climate change, and carbon sequestered in forest biomass reduces carbon dioxide in the atmosphere.

As atmospheric CO2 levels increase from burning fossil fuels, this carbon dioxide is soaked up by seawater and makes the oceans more acidic.

Coral is already threatened by insidious change in sea water chemistry as ever more carbonic acid — from dissolved atmospheric carbon dioxide, the product of the combustion of fossil fuels — gets into the sea.

Now, if there's a single take - away from this summary, it would be that the science on the relationship between fossil fuel combustion, rising atmospheric carbon dioxide, and global warming and climate change was really settled by 1979.

[UPDATED 6/23, 9:30 a.m.] Twenty years ago today, James E. Hansen testified before the Senate Energy Committee — in a room kept intentionally warm by committee staff — that the atmospheric buildup of carbon dioxide and other greenhouse gases from burning fossil fuels and forests was already perceptibly influencing Earth's climate.

Otherwise it will become impractical to constrain atmospheric carbon dioxide, the greenhouse gas produced in burning fossil fuels, to a level that prevents the climate system from passing tipping points that lead to disastrous climate changes that spiral dynamically out of humanity's control.

«Due to human activities such as the combustion of fossil fuels and deforestation, and the increased release of CO2 from the oceans due to the increase in the Earth's temperature, the concentration of atmospheric carbon dioxide has increased by about 35 % since the beginning of the age of industrialization.»

«According to the cover story in Nature, the fires in Indonesia released upwards of 2.57 gigatonnes of carbon, 40 percent of the mean carbon emissions released annually from fossil fuels, and «contributing greatly to the largest annual increase in atmospheric carbon dioxide concentration detected since records began in 1957.

For example, atmospheric carbon dioxide grew by approximately 30 % during the transition from the most recent cold glacial period, about 20,000 years ago, to the current warm interglacial period; the corresponding rate of decrease in surface ocean pH, driven by geological processes, was approximately 50 times slower than the current rate driven largely by fossil fuel burning.

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.

Traditional anthropogenic theory of currently observed global warming states that release of carbon dioxide into atmosphere (partially as a result of utilization of fossil fuels) leads to an increase in atmospheric temperature because the molecules of CO2 (and other greenhouse gases) absorb the infrared radiation from the Earth's surface.

The researchers discovered a temperature increase of just 1 degree Celsius in near - surface air temperatures in the tropics leads to an average annual growth rate of atmospheric carbon dioxide equivalent to one - third of the annual global emissions from combustion of fossil fuels and deforestation combined.

Since the beginning of the Industrial Revolution (taken as the year 1750), the burning of fossil fuels and extensive clearing of native forests has contributed to a 40 % increase in the atmospheric concentration of carbon dioxide, from 280 ppm in 1750 to 392.6 ppm in 2012.

¶ ¶ 38 («when used -LSB-,]... fossil fuels release greenhouse gases), 39 («use of fossil fuels emits carbon dioxide»), 45 («emissions resulting from human activities are substantially increasing... greenhouse gases»), 48 («increase in atmospheric carbon dioxide caused by the combustion of fossil fuels»), 52 («fossil fuels -LSB-,]... when combusted, emit carbon dioxide»).

This would then lead to large, unpredictable changes in ocean ecosystem structure and productivity, on top of other large unpredictable changes to be expected from ocean acidification, the other great oceanic consequence of high atmospheric carbon dioxide concentrations from fossil fuel burning.

The «A1B» scenario assumes that 50 % of energy over the next century will come from fossil fuels, resulting in atmospheric carbon dioxide concentrations causing drastic climatic consequences.
