AP Newsbreak: Obama looks at climate engineering
By SETH BORENSTEIN – 2 days ago
WASHINGTON (AP) — The president's new science adviser said Wednesday that global warming is so dire, the Obama administration is discussing radical technologies to cool Earth's air. John Holdren told The Associated Press in his first interview since being confirmed last month that the idea of geoengineering the climate is being discussed.
One such extreme option includes shooting pollution particles into the upper atmosphere to reflect the sun's rays. Holdren said such an experimental measure would only be used as a last resort.
"It's got to be looked at," he said. "We don't have the luxury of taking any approach off the table."
Holdren outlined several "tipping points" involving global warming that could be fast approaching. Once such milestones are reached, such as complete loss of summer sea ice in the Arctic, it increases chances of "really intolerable consequences," he said.
Sooooooooooo....have you ever wanted to know what chemtrails are?????

I thought our laws on vehicle emissions and mpg were on the stricter end compared to federal requirements.
As far as the approach to global warming I might support the reflection technology if it seemed a viable solution. Would rather see if early preemptive steps towards reducing our effect on the environment's warming may be more effective than trying to address the symptoms though.
For three decades, California has set the benchmarks for auto emission standards..In 1990, the California Air Resources Board adopted a regulation requiring that 2% of new car sales by 1998. 5% by 2001 and 10% of all large automobiles sold from 2003 onward be zero-emission vehicles (ZEV's) — cars powered by electricity or alternative fuels, like hydrogen. The idea was to encourage auto companies to incubate new technology rather than simply make internal combustion engines cleaner...
California law AB 1493, of the Pavley bill, so named for its sponsor Fran Pavley, is the first law in the nation to address the greenhouse gases, especially carbon dioxide, emitted in auto exhaust. The law requires the California Air Resources Board (CARB) to regulate greenhouse gases as part of the California Motor Vehicle Program. Under the Pavley bill, automakers will have until the 2009 model year to produce a new California breed of cars and trucks that will collectively emit 22 percent fewer greenhouse gases by 2012 and 30 percent fewer by 2016. Seven Northeastern states, including New York, have pledged to adopt the California standards...
# 1966 - Auto tailpipe emission standards for hydrocarbons and carbon monoxide are adopted by the California Motor Vehicle Pollution Control Board. They are the first of their kind in the nation. California Highway Patrol begins random roadside inspections of vehicle smog control devices.
# 1969 - First state Ambient Air Quality Standards are promulgated by California for total suspended particulates, photochemical oxidants, sulfur dioxide, nitrogen dioxide, and carbon monoxide
# 1976 - California limits lead in gasoline.
# 1988 - California Clean Air Act is signed by Governor Deukmejian. Sets forth the framework for how air quality will be managed in California for the next 20 years
# 1990 - California approves standards for Cleaner Burning Fuels and Low and Zero Emission Vehicles.
# 1999 - In California consumer products rules were adopted to cut smog-forming emissions and volatile organic compounds (VOC) from an estimated 2,500 common household products ranging from nail polish remover to glass cleaners.
Not ideal, we also have some of the worst air quality in the nation. Getting better though.

Ya but all that smog would reduce the suns effect and lower the temp
In all reality, they just need to stop messing with the world, let it take care of itself.

Agreed
Just saying , CA is pretty good about setting good environmental regulation that ends up being passed on to other states.

holy crap, so you will support whatever the latest "feel good" solution that is put out there ?
**** man i wish i still had my old ass bronco that got like 8 MPG and had no emissions equipment on the engine.
the whole issue of mankind causing "global warming" is what i have an issue with Humby, but if you want to do something that you think is "helping", more power to ya
It’s great more attention is being paid to taking care of the planet we live on. I wonder though how much of what we are trying to undo is really the natural progression of the planet and in trying to fix things we really are screwing up something.

And the Jefferson Parish Sheriffs Office SWAT team uses them for target practice. Late at night the cops line up on the canal and shoot them. Then they pick up the dead nutria and feed them to the gators at theAudubon Zoo.
I’m sure that wads up the panties of some of the PETA types but oh well. Those things are destroying our drainage canals and they shouldn’t be around here in the first place.
The report “I’ll Be Here Long After You’re Gone ” by Marilyn Barrett reprinted from the Volume 5 No.1 Spring/Summer 1996 edition of the Louisiana Sea Grant College Program’s Coast & Sea Magazine documents the erosion problem caused by nutria within the Jefferson Parish Storm Drainage System. Ms. Barrett’s article refers to a 1995 study by Dr. Robert Chabreck and Dr. J. Andy Nyman wildlife management experts. This study was commissioned by the Jefferson Parish Council to determine the size of the nutria population in the Parish and to evaluate means of controlling it. To see the Executive Summary of that study click here.
The Jefferson Parish Sheriff’s Office SWAT team continues their very successful nutria control program in Jefferson Parish. However it is important that the state and federal government continue and upgrade their efforts to control this invasive species.
Eradicating nutria in the burbs around New Orleans requires perfect shooting every time. We wouldn't want a bullet to fly into someone's living room, knocking over coffee-table bowls of potpourri and such.
Yeah, we as mankind are our own worst enemies.

HAI!!
back to the geo-engineering thing....
in my own myopic outlook, i think its one of those things that on the surface would appear to be a splendid idea. your typical joe lunchbox will think "ah, i get it. that makes sense", but in reality the sheer scale of what we're talking about makes it unrealistic.... be it covering the worlds glaciers and ice shelves/caps in white blankets to decrease their shrinkage, or scattering mirrors/prizms around in the space between earth and the sun to reflect/scatter the sun's energy, or whatever method..... i just dont see it as being a practical place to invest our efforts. it's the true scale involved that (imho) makes it more realistic to focus on other ideas. either spend our time fixing the SOURCE of the problem here (carbon credits my ass. what a crock), or start making strides to have a new home ready when we're done trashing the one we have now.
The current administration has basically proven that no problem is too big. We'll just throw money at it, and when we run out, we'll print more. So let's get it on with throwing big umbrellas up into space.

Whatever Mark.
I never said I bought into or supported anything being suggested.
Just that I'm not opposed to new technologies being considered.
