That just proves that human use of natural gas has nothing measurable to do with atmospheric methane levels.

Not exact matches

Known as a «co-benefit,» using state of the art models for human and natural systems, along with climate projections from the international community, the team was able for the first time to put a value on the global air pollution benefits of cutting greenhouse gas emissions over the 21st century.

Climate change is driven by human activity — chiefly the combustion of fossil fuels and changes in land use — and forests and other natural ecosystems play a powerful role in both soaking up the greenhouse gases released by human economic activity and at the same time sheltering many of the other 10 million or so species that share the planet.

7 - Human use of coal, oil, and natural gas has not harmfully warmed the Earth, and the extrapolation of current trends shows that it will not do so in the foreseeable future.

Drilling the crude oil, coal and natural gases from an beneath the earth has a number of environmental challenges such as extensive land deformation and deforestation; which leads to a wastage of productive land that can be used as a plantation to boost the economy, water catchments and to grow human food.

On the question of hurricanes, the theoretical arguments that more energy and water vapor in the atmosphere should lead to stronger storms are really sound (after all, storm intensity increases going from pole toward equator), but determining precisely how human influences (so including GHGs [greenhouse gases] and aerosols, and land cover change) should be changing hurricanes in a system where there are natural external (solar and volcanoes) and internal (e.g., ENSO, NAO [El Nino - Southern Oscillation, North Atlantic Oscillation]-RRB- influences is quite problematic — our climate models are just not good enough yet to carry out the types of sensitivity tests that have been done using limited area hurricane models run for relatively short times.

When Gort first visited in 1951, it spent little effort on climate change issues, focusing on other aspects of our planet instead: Gort returned in 2012 to answer puny human climatologist questions about whether climate change caused particular weather phenomena by making an obvious point: rather than struggle with theoretical analysis, you can simply use your Climate Changeometer to remove all the excess greenhouse gases and aerosols above natural levels and then measure the outcome.

It does have the disadvantage that fracking for natural gas reduces emissions of CO2 compared to coal, but this is well worth it for providing the advantages of improving human lives by using plentiful, inexpensive gas and oil.

The model included a more comprehensive set of natural and human - made climate forcings than previous studies, including changes in solar radiation, volcanic particles, human - made greenhouse gases, fine particles such as soot, the effect of the particles on clouds and land use.

The SRI industry uses a variety of excuses for why it generally continues to support fossil fuels, or to prefer natural gas over oil as a «better» option, but the primary rationale seems to be one of doing less harm or favoring financial return rather than being truly concerned about ecological or human welfare.

Larger image to save or print.The main human activity that emits CO2 is the combustion of fossil fuels (coal, natural gas, and oil) for energy and transportation, although certain industrial processes and land - use changes also emit CO2.

[7][8] The vast majority of anthropogenic carbon dioxide emissions (i.e., emissions produced by human activities) come from combustion of fossil fuels, principally coal, oil, and natural gas, with comparatively modest additional contributions coming from deforestation, changes in land use, soil erosion, and agriculture.
