Sentences with phrase «blocked by greenhouse gases»

Not exact matches

But the planets surface will be warmer, because a larger fraction of that infrared will be blocked by the blanket of greenhouse gases.

That's part of the reason why the IPCC included a final paragraph on geoengineering, or large - scale attempts to alter the climate by either blocking sunlight or removing CO2 (or other greenhouse gases) from the atmosphere.

It's not totally about how much infrared from the surface that is blocked (currently about 90 % of surface emissions is absorbed by greenhouse gases), its also about the height within the atmosphere from which radiation escapes.

The argument for geoengineering goes like this: the world is getting inexorably warmer; governments show no sign of drastically reducing greenhouse gas emissions, so why not control the planetary thermostat by finding a way to filter, block, absorb or reflect some of the sunlight hitting the Earth?

It's worth spending some more time on the National Academy of Sciences reports on geoengineering prospects and concerns — the concerns mainly being about adding sun - blocking particles to the atmosphere to counteract global warming driven by the buildup of heat - trapping greenhouse gases.

Some conscientious climate scientists have tried hard and successfully to block discussion of geoengineering because they fear that such discussion would diminish support by the public and by government leaders for the painful, expensive task of reducing the rate at which we put greenhouse gases into the atmosphere.

Photo For years, politicians wanting to block legislation on have bolstered their arguments by pointing to the work of a handful of scientists who claim that greenhouse gases pose little risk to humanity.

WASHINGTON, D.C. — A new offshore oil and gas plan from the U.S. Department of the Interior blocks two drilling leases in the Arctic, but allows a new lease in Alaska's Cook Inlet and 10 new leases in the Gulf of Mexico over the next five years — a step that will worsen climate change by ensuring significant greenhouse gas pollution for the next 70 years.

In this report the State Department concluded that by tapping into the oil sands, KXL would produce more greenhouse gases, but that blocking the project would not prevent development of those resources.

Greenhouse gases don't block all outgoing radiant energy — it merely slows it down by capturing more infrared photons and re-emitting in all directions including down — increasing net energy retained at any instant in the atmosphere.

Sen. Lisa Murkowski, R - Alaska, joined by other Senate colleagues, talks about her efforts to block the Environmental Protection Agency from issuing greenhouse gas regulations, during a news conference on Capitol Hill Tuesday.

In addition to altering marine food webs, iron fertilization could produce greenhouse gases more potent than carbon dioxide, such as nitrous oxide and methane, or block sunlight needed by deep coral reefs.

And, according to the Ecosystem Climate Alliance, when it comes to aspects of the REDD forest protection scheme the European Union is actively blocking protecting intact forests from being converted to plantations: The ECA says the blocking by the EU — with the support of the Democratic Republic of Congo, Cameroon, Equitorial Guinea and the Republic of Congo — of language to prevent forest - to - plantation conversions essentially means that «industrial - scale logging and replacement of tropical forests with pulp or palm oil plantations could be funded by money intended to help developing countries reduce the 25 % of greenhouse gas emissions from deforestation, forest degradation and peatland destruction.»
