Sentences with phrase «reduction impact on global warming»

Not exact matches

«Reductions of methane and black carbon (soot) would likely have only a modest impact on near - term global climate warming,» the authors at the U.S. Department of Energy's Pacific Northwest National Laboratory wrote.

What simply amazes me (TonyB seems to agree) is that U.K. and other jurisdictions have enacted laws to mandate greenhouse gas reductions with HUGE impact on the taxpayers» lives without any evidence that they have even thought about the effectiveness of their programs in actually reducing global warming.

The nations that have pledged to voluntary reductions (EU, Australia, New Zealand) would have no discernable impact even if they shut down completely and there have been no actionable proposals by anyone, which if implemented now would cause a discernable impact on global warming by 2100.

A global phase - down could avoid 1.1 — 1.7 billion metric tons CO2 equivalent (CO2 equivalent is a measure used to compare impacts of greenhouse gases based on their global warming potential in relation to CO2) of GHG emissions per year by 2030, with cumulative emission reductions of nearly 100 billion metric tons CO2 equivalent by 2050.

The alleged rationales for anti-coal and gas policies — to reduce global warming or protect local environments — are furphies: whether or not further warming will occur and be dangerous — and both propositions are questionable and are being ignored by major emissions producers China and India, and soon the USA — Australia's emissions reductions will have no measurable impact on world climate.

Reductions in emissions of black carbon since the late 1980s, mostly from diesel engines as a result of air quality programs, have resulted in a measurable reduction of concentrations of global warming pollutants in the atmosphere, according to a first - of - its - kind study — which Berkeley Lab participated in — examining the impact of black carbon on California's climate.

Sacramento — Reductions in emissions of black carbon since the late 1980s, mostly from diesel engines as a result of air quality programs, have resulted in a measurable reduction of concentrations of global warming pollutants in the atmosphere, according to a first - of - its - kind study examining the impact of black carbon on California's climate.

«Climate science» as it is used by warmists implies adherence to a set of beliefs: (1) Increasing greenhouse gas concentrations will warm the Earth's surface and atmosphere; (2) Human production of CO2 is producing significant increases in CO2 concentration; (3) The rate of rise of temperature in the 20th and 21st centuries is unprecedented compared to the rates of change of temperature in the previous two millennia and this can only be due to rising greenhouse gas concentrations; (4) The climate of the 19th century was ideal and may be taken as a standard to compare against any current climate; (5) global climate models, while still not perfect, are good enough to indicate that continued use of fossil fuels at projected rates in the 21st century will cause the CO2 concentration to rise to a high level by 2100 (possibly 700 to 900 ppm); (6) The global average temperature under this condition will rise more than 3 °C from the late 19th century ideal; (7) The negative impact on humanity of such a rise will be enormous; (8) The only alternative to such a disaster is to immediately and sharply reduce CO2 emissions (reducing emissions in 2050 by 80 % compared to today's rate) and continue further reductions after 2050; (9) Even with such draconian CO2 reductions, the CO2 concentration is likely to reach at least 450 to 500 ppm by 2100 resulting in significant damage to humanity; (10) Such reductions in CO2 emissions are technically feasible and economically affordable while providing adequate energy to a growing world population that is increasingly industrializing.

To minimise the anticipated impact of global warming on the ski industry, development of new leisure industries more resistant to or suited to a warmer atmosphere, thus avoiding excessive reliance on the ski industry, e.g., grass - skiing, hiking, residential lodging and eco-tourism, could be helpful in compensating for the income reduction due to snow deterioration (Fukushima et al., 2002).

Wind / solar are limited to a small percentage of the total, due to the inherent lack of reliability — and, when you calculate in the CO2 from the required gas - fired standby plants for the 75 - 80 % of the time they are idle, there is very little net reduction in CO2 and essentially no impact on global warming.

Whether or not global warming is entirely or largely due to human use of carbon for fuel, the reduction of the dependence on carbon makes sense for reducing asthma in children; reducing black lung disease; reducing the production of coal ashes, residues, and effluents; reducing the impact of carbon greenhouse gasses; reducing pipeline failures; reducing coal and oil surface transport accidents; reducing pipeline - related warfare; and reducing air pollution.

Other surprises include the recognition that reducing methane emissions from whatever source has important indirect impacts on a range of other drivers and is a more effective strategy for short - term reductions in global warming than had been previously recognized.
