Global Warming: We Will Need Climate Engineering

By 2060 Phoenix Arizona will have 132 days a year over 100F. Dallas will 55 and Pecos Texas 101 days.

My view about problems: We should solve them. If the Earth really does heat up substantially then we should pull the CO2 back out of the atmosphere while also releasing cooling gases. If its practical we should also raise the albedo (surface reflectivity) of the planet.

Right now cities should change their zoning laws and roads policies to make buildings, roads, and other surfaces more reflective. No more dark buildings. Use light colors of concrete, white shingles, and other surfaces that reflect more light. That would be beneficial even if the Earth was not heating up. Hot cities are unpleasant places to live.

I could tell you we should do big build-ups of nuclear, wind, and solar power. But right now the will does not exist to take radical steps. Luckily, wind and solar are getting much cheaper. Unluckily, nuclear does not appear to be getting cheaper. Batteries for electric vehicles are getting cheaper but at much too slow a pace to cause a slashing in demand for fossil fuels.

The human race has a number of big problems that have to get much worse before they'll be addressed effectively.

Utter nonsense. We are experiencing a minor up fluctuation on the long term trend down to the next ice age. We are about where we were in the 1930s. We are cooler than the Medieval Climate Optimum, which was cooler than the Roman expansion, which was cooler than the Minoan floruit, which was cooler than the early neolithic.

The Vostok ice cores, which Gore uses as a backdrop, show that temperture changes lead CO2 by 400 to 800 years--ie, temperature drives CO2. Something (probably the Sun) drives temperature, and ocean outgassing and readsorption drive CO2. The current warming also leads the current CO2 increase. We have had 20 years of increasing CO2 without any increase in temperature.

the current global warming hype is not about global warming.I don't fully understand what is going on but seems to have something to do with a global taxation scheme.Does anyone know where we stand in the current melankovich cycle?

The cost of nuclear is set by the burden of government regulations; there is no luck involved.  This is why China and S. Korea can build nuclear on time and on budget for a fraction of what it costs in the USA.

In reality. No one knows what Phoenix's weather will be like 40 years from now.

Bullshit. The world may have some big problems like too much poverty and lunatic muslims, but gerbil warming isn't one of them.

"We have had 20 years of increasing CO2 without any increase in temperature."

Unless of course you "adjust" the earlier data downward to make the warming hiatus go bye-bye; then that makes the current temperature the hottest on record.

Professor Parker,

You recently posted an article on your blog ( that I did enjoy very much. I am just a little confused. What is your take on climate change? What are the facts and what is the noise? I am very interested in what you have to say on the subject. I have been a reader of your blog and the "para" web sites since the Joe Jihad has a bad day postings. I am also a former student of yours and to this day you are the best professor I ever had. Your blog and web posting are required reading and have had a huge impact on how I advised my daughter through her education and career choices. (She is going into Medical School fall 2017). Thank you again for taking the time to blog and post on the internet. Best of everything.

we have bigger problems like insane Muslims who suicide bomb,poverty and so on. Global warming to me isn't one of them.

My biggest worry with global warming is rising seas. I think we could freeze the glaciers in Antartica at the bottom in a ring around the continent. This would keep them from sliding. It's not as farfetched as it sounds:
(1) Most of the loss of continental ice is from glaciers sliding fast into the sea rather than them melting on land
(2) Glaciers move fast because there's a tiny layer of water at the bottom
(3) The reason there is water at the bottom is because of a weak flux of geothermal heat gets trapped under a very thick layer of ice which is a good thermal insulator. The balance has been upset with global warming
(4) To freeze the glacier, you just need to drill every 1/2 mile or so a loop of thick PEX that goes to the bottom of the glacier. We recently learned how with the neutrino detector
(5) Pump sub-zero chilled brine thorugh the pex. power the chillers with wind turbines. Dump the heat from the chiller into a something that radiates to the sky at night

If you run the calc's, the energy demands aren't as crazy as it sounds. A small amount of chilling at the bottom will tack the glaciers to the ground.

Or we are about to enter another ice age.

We need to help out mother nature to combat climate change

Faked temperature data from politicized sources aren't convincing anyone except the gullible and alarmist trolls. Remember, CO2 follows temperature change rather than causes it...smh
