Scientists dim sunlight, suck up carbon dioxide to cool planet

I must laugh to keep from crying.

Dumb.

Theres gotta be $ in for someone to be talking about pulling a stunt like this !

There are no limits to the infinite stupidity of these God playing control freaks. On top of that we are all going to be taxed more and more to fund them

There is a simple and natural solution which is already at work. Plants consume CO2, and the increase in CO2 has led to an increase in the earth's plant cover. Satellite photos have show increased "greening" around the world as plants have reacted to the increase in CO2. If CO2 levels continue to increase, so will plant consumption of C02.

We seem forget that the current level of CO2 in the atmosphere (400 ppm) is a fraction of the average level over the past 65 million years (2500 ppm). CO2 levels have been as high as 7000 ppm, and yet the world did not end.

The plan detailed above is a nice way for the state and it's cronies to spend a few billion dollars of our money. Al Gore is on his way to being the first "carbon billionaire". His net worth was $1.5 million when he left office as vice president, he is now worth $300 million. There's a lot of money to be made in fighting climate change.

And you seem to forget that while the wold didn't end back then, a double-digit percentage of all life on earth went extinct within the course of a few thousand years each time one of these fluctuations happened. This isn't a matter of making the world into a barren wasteland, but making enough changes to disrupt fishing and agriculture, leading to millions of deaths. Try to see the big picture please.

Another solution: population reduction.

Burring Co2 is not the Answer to our earths Problems It has to be converted into a solid Like Limestone then Used as a Construction Material eg Cement for Concrete Simply Shale Limestone or Lime Co2 mig then into long tube rotary angled tumbler furnace The clinker then Crushed Bagged and gorn forever as a solid.

Very true!

Plus algae and cyanobacteria in the oceans will also take up a lot.

Hasn't anybody learned after watching Highlander 2?

Attempting to such CO2 out of the atmosphere in his way is doomed to failure, it consumes energy which mitigates any beneficial impact it might have, is stupidly costly and way too ineffective to be worth while.

Yes plants can absorb CO2 so reforresting the rainforests would be a good start but what they all forget is the earth has a very efficient mechanism for regulating the CO2 level through absorption by rocks, it is just too slow to deal with the massive overload created by man. Many mining operations expos or dig up the appropriate rocks, they just need to be broken down to increase the surface area and spread out ( not currently done as no economic case) but could be done as part of the environmental offset to their activities.

Geo-engineering has many problems in implementation as it can have positive and negative impacts and the countries suffering the negative impacts are likely to get ratty over something imposed for the benefit of another country. Worse yet we have little or no understanding of the long term and peripheral impacts, so would be foolish indeed to attempt it.

Well, at least they're trying to find solutions, instead of just surrendering and letting things happen unchallenged before even finding out if they can do something about it

On top of that we are all going to be taxed more and more to fund them

Except that pretty much all of these are privately funded, by donations from the public and from people like Bill Gates. I highly doubt there's many countries, if any, that are going to raise taxes to fund these. Except maybe Canada.

They might sound like oddball ideas, but to be honest, they're more realistic than simply cutting emissions. Especially since America pulled out of the Paris Climate Accord, and that's one of the world's biggest Carbon Dioxide producers. China's another big one, but they couldn't even cut back on polluting for the Olympics. No way they're going to do it for the environment. So it falls to the more eccentric of people to come up with ideas that don't rely on governments reducing emissions.

"We're in trouble," said Janos Pasztor, head of the new Carnegie Climate Geoengineering Governance Project. "The question is not whether or not there will be an overshoot but by how many degrees and for how many decades."

A very true statement, and that's why we're likely to need these unusual methods to combat global warming. If we don't act fast, nature is going to suffer as a result. The Great Barrier Reef is already undergoing massive bleaching, and I believe reefs around Japan are starting to do the same. Heatwaves are getting hotter and lasting longer, bringing with them wildfires that devastate the landscape. We can't rely on our governments to solve the problem, so we're going to need to look elsewhere. The only people who seem willing to step up to the plate are these Geo-engineers.
