James Lovelock Quotes

For relatively modest amounts of sulfur dioxide injected into the atmosphere, you could easily cool Earth by 1% or more, if you want.

There are many theories about the best way to remove excess carbon from the atmosphere - some are ludicrous, others are at least worth study. The most commonly discussed plan is to lace the sky with reflective chemicals.

Geoengineering involves humans making intentional, large-scale modifications to the Earths geophysical systems in order to change the environment.

To be clear, geoengineering won't solve global warming. It's not a 'techno-fix.' It would be enormously risky and almost certainly lead to troubling unforeseen consequences.

Many of the most science-fictional tools to fight climate change are untested, are almost impossible to truly test at planetary scale - we only have one planet after all. We're better off cutting our emissions so we don't need them.

I was born behind the Iron Curtain, and I remember heated discussions about large-scale terra-forming projects, such as reversing the direction of the river Ob or putting up large reflectors into space to heat up Siberia.

Geoengineering means changing the Earth's fundamental large-scale processes.

As for geoengineering, there have been serious general critiques that I think cannot be ignored, like Clive Hamilton's, along with many positive assessments. It is not a matter for subjective judgment based on guesswork and intuition. Rather, these are matters that have to be considered seriously, relying on the best scientific understanding available, without abandoning sensible precautionary principles.

The Environmental Control and Life Support System (ECLSS), which controls the living environment on shuttles and on the International Space Station, doesn't have the luxury of disposal: discharging trash into space has long been judged a bad idea.

The Space Shuttle will stop directly below the Space Station and Sergei and I will be looking out two different windows looking straight down at the Space Shuttle.

You can't tie a rope around the ice sheet. You can't build a wall around the ice sheets.

If the United States commits to the goal of reaching Mars, it will almost certainly do so in reaction to the progress of other nations - as was the case with NASA, the Apollo program, and the project that became the International Space Station.

Finally my dream came true in that there was a possibility that I could travel to the International Space Station. I've gone through the medicals and the training and now I'm officially, by the Russian Space Federation, a cosmonaut in training.

Deliberately modifying the earth's atmosphere would be a desperate gamble with significant risks. Yet the more likely climate change is to cause devastation, the more attractive even the most perilous attempts to mitigate those changes will become.

Through these ongoing activities and possibly in the future, a Canadian will go live and work on the International Space Station and we will continue to make Canadians proud of our achievements in space.

While on the space station, I kept up with news a couple of ways - Mission Control sent daily summaries, and I would scan headlines on Google News when we had an Internet connection, which was about half the time.

Canada has made a strong commitment as a partner in the International Space Station and, like the other partners, wishes to see the assembly of this unique orbiting laboratory continue.

After the Shuttle checks out on its two upcoming flights, it will be ready to take larger components up to the International Space Station later this fall.

When the International Space Station is finally launched, it will be fitted with special nickel-hydrogen batteries weighing a total of several tons, with a lifetime of just five years, requiring spares to be brought up from Earth at literally astronomical expense.

While we've taken seeds into space, and astronauts on the International Space Station have eaten lettuce they've grown, we haven't produced fruit in space, so we can't pollinate something.

Global warming and climate change is a big problem. It requires a big solution.

We have hysteria over climate change. Powers bigger than us have already figured out how to save the earth.

The most galling examples are people who argue against researching geoengineering on the basis that we already know how to solve the climate problem. To them, the climate problem is a done deal, we just haven’t implemented yet. I think that is just absurd, but you see smart people make this argument.

The American people know that climate change is the kind of problem only America can solve.

Donald Trump's administration is floating a proposal to return to the moon - and to shut down the International Space Station to help pay for it. The first part of this idea is good. The second is horrible.
