The dams, coal mines and machinery that move water to Arizona cities constitute a modern marvel, but the power plant that runs it spews air pollution that is a disaster; and global heating is reducing the water available for the system to move.

Note that water that seeps into the ground from Lake Powell and water canals may not really be a waste, if it helps refill aquifers that we are emptying. But I don't know the details of this.

US citizens: see how your congresscritter voted on "fast track" for corporate-supremacy treaties, then call to express praise or disgust.

Don't accept the description of the TPP, TTIP and TISA as "free trade" treaties. They are not about trade, they are about subjecting democracy to company power.

The Capitol Switchboard numbers are 202-224-3121, 888-818-6641 and 888-355-3588.

US citizens: call on Congress not to cut food stamps.

A journalist who has interviewed people that joined PISSI reports on their motives.

Some Muslim women (especially teenagers) attach their hopes for safety or justice to PISSI. The loss of equal rights doesn't worry them because they live in stultifying communities where in practice they have few rights to lose.

Carbon capture and storage (CCS) has been implemented in a commercial power station. The practice is therefore feasible. Now what?

With solar and wind power, plus more electricity storage, we can eliminate fossil fuel electric generation. That would take time, and lots of money, but so would applying CCS. Which one can we do faster and cheaper? I don't have a calculation, but I think it is the renewable path. If so, developing CCS for attachment to fossil fuel power plants is a distraction from replacing those plants.

Fossil fuels have other drawbacks: extracting them spreads pollution and occasionally causes disasters, and burning them creates other pollutants besides CO2.

The form of CCS that could be more significant is the one that pulls CO2 out of the air. With money, that method could be applied in hot dry places to extract the CO2 made by burning fossil fuels for reasons other than electric generation.

That would be cheaper than suffering the CO2 to remain in the air.
