Re-Ice the Arctic
As we are aware, Arctic ice is melting fast, diluting the salty seas with freshwater. This would result in weakening the ocean currents that help regulate the global climate by transporting heat around the globe. Any change to this would have disasterous affects on life in general. But according to Industrial engineer Peter Flynn of the University of Alberta, the idea is to make more Arctic ice, and make it salty ”by towing 8,000 ice- making barges to the Arctic, and make a salty ice cube the size of New Mexico!” (popsci.com)

Tame Storms With Cold Water
Climate change they say is warming the oceans which in turn fuel hurricanes. So what do you do? Simple. Cool down the warm surface water. New Mexico inventor Phil Kithil has hit upon an idea to put 1.6 million ocean-cooling "pumps" into the Gulf of Mexico, anchor them to the seafloor, and presto! The storms attenuate to almost nothing. But then it would take four months, some 100 barges and $5 billion to install! (popsci.com)

New data shows ocean cooling
By DENNIS AVERY and ALEX AVERY
The world's oceans cooled suddenly between 2003 and 2005, losing more than 20 percent of the global-warming heat they'd absorbed over the previous 50 years. That's a vast amount of heat, since the oceans hold 1,000 times as heat as the atmosphere. The ocean-cooling researchers say the heat was likely vented into space, since it hasn't been found stored anywhere on Earth.
“Heat waves are becoming more common, intense, prolonged, and widespread, and disproportionate warming at night and higher humidity as a result of climate change are exacerbating the health consequences. This study by U.S. PIRG dramatizes the issue for the United States, which must prepare for more summers like that of 2006, while taking concrete action to reduce harmful emissions,” said Paul R. Epstein, the Associate Director of Harvard Medical School’s Center for Health and the Global Environment.

This study examines the trends and variation patterns in daily maximum (day-time) and minimum (night-time) temperatures (hereafter referred to as Tm and Tn), extreme events, and growing season lengths over the eastern and central Tibetan Plateau (TP), in comparison with the results from other regions. Data during the period 1961-2003 from 66 weather stations over the eastern and central TP with elevations above 2000 m are used in this study, after going through rigorous quality assessment/quality control procedures. Statistically significant warming trends are identified in various measures of the temperature regime, especially in night- time temperatures, extreme warm/cold events, and diurnal temperature range (DTR).

GLOBAL HEATING FOUND HIGHER AT NIGHT
Global warming is occurring mostly at night, a new study has
confirmed, and scientists caution that we had better find out why,
or the earth's climate in the future may turn out to be far from
what we expected.
Over the past 40 years, temperatures have been rising much faster
at night than during the day, scientists from Columbia's Lamont-
Doherty Earth Observatory and the National Oceanographic and
Atmospheric Administration report in the August issue of
"Environmental Science Technology." Using data from more than
1,000 weather stations in 12 countries, mostly in the Northern
Hemisphere, they report:

Grow Super-Trees in Factories
It is said that the world's rainforests lose about 100,000 acres and as many as 100 species every day. Experts predict that the rainforests could be wiped out by 2050, with disastrous consequences. ArborGen, a biotech company in Charleston, South Carolina, is conducting research that will help farmers mass-produce genetically modified trees. They plan to mass produce designer seedlings in fully automated tree factories. Needless to say the transplanting will be carried out by robots that will be designed by them! Cost? Unknown.

Build Wetlands From Scratch
Wetlands, home to thousands of bird and animal species are fast depleting. This will result in loss of water quality, increased flooding of surrounding areas and the consequent extinction of many species. But there’s hope. As per inventor Bruce Kania, all one has to do is ”construct small archipelagos/islands the size of basketball courts out of recycled plastic and foam, plant habitat-specific vegetation, and set the islands afloat wherever natural wetlands once thrived.” (popsci.com)
Time line? Unknown. The sun would’ve probably become a red giant by then!

Insulate the Glaciers
Glaciers, which are earth's largest freshwater reservoirs, are melting at an alarming rate, shrinking by up to hundreds of feet per year in some places. Probably 75% of all glaciers would have completely melted by 2050, and perhaps nothing would be left by the end of the century. All you’ve got to do is ”wrap the thawing glaciers in football-field-size synthetic blankets that keep the cold in and the heat out”, as per Fritz Landolt, a textile manufacturer. (popsci.com)
How many millions of square feet are required for covering the thousands of glaciers? Cost? Time? (The darn outfitters took 3 weeks to make a party suit of mine. And I’m just about 6 feet tall! )

Great ideas, but how practical are they? How many billions is it going to cost and of course, there’s the time line to contend with! Why don’t we come to grips with controlling climate change in the first place, by reducing GHG emissions? Why don’t we spend those billions on control instead of trying to shut the stable after the horses have bolted, and spending billions more? I gotta ask Bush this. But darn! Dubya’s busy fighting that war in Iraq and chasing his friend Bin Laden all over the place.
