How global warming works in 5 minutes

A team at Berkely have created a series of videos to education the public on the basics of global climate change. It’s worth a look and it doesn’t take long.


TEDx Inspirational Speaker Croix Sather – Do The Impossible

People keep telling me things like, “we can’t do that because it won’t work, it will ruin the economy or it would cost too much.” This is usually related to finding solutions to climate change. They think that transforming our energy production will somehow ruin the economy. Germany’s success in renewable energy while improving its economy is proof that it’s just not true. Others claim that if we increase the cost of fossil fuels by way of a carbon tax it will make so that people living in poverty can’t afford energy. So help the people get out of poverty. We don’t have a problem with generating wealth we just have a problem with its distribution. People who say, “I can’t” don’t accomplish much. We have to take the initiative and think positively about what we do or we’ll never get there. Yes, it will require some pain and sacrifice. We can’t afford to give up. The alternative would be a lot more painful and more costly. Just ask the insurance companies. They are losing a lot of money to costly disasters related to rising sea levels and more intense storms. Solving the problem now would be a lot cheaper than suffering the consequences later.

Reponse to “Reversing Climate Change Cannot Be Accomplished Via Geoengineering: Researchers”

Since I have made a proposal for geoengineering by building a Planetary Solar Shield this article quickly got my attention.

Geoengineering the climate has been suggested as a way to help lessen the impact of climate change, but new research published in Earth System Dynamics says this approach would not likely succeed.

German researchers say that reducing the amount of sunlight reaching the planet’s surface by geoengineering may not undo climate change.

The team used a simple energy balance analysis to explain how the Earth’s water cycle responds differently to heating by sunlight than it does to warming due to a stronger atmospheric greenhouse effect. They show that this difference implies that reflecting sunlight to reduce temperatures may have unwanted effects on the Earth’s rainfall patterns.

Many geoengineering approaches try to reduce global warming by reducing the amount of sunlight reaching the Earth’s surface. However, when the team applied their results to a geoengineering scenario like this, they found out that simultaneous changes in the water cycle and the atmosphere cannot be compensated for at the same time. This scenario would mean that reflecting sunlight by geoengineering is unlikely to restore the planet’s recent climate.

“It’s like putting a lid on the pot and turning down the heat at the same time,” Kleidon said in a statement. “While in the kitchen you can reduce your energy bill by doing so, in the Earth system this slows down the water cycle with wide-ranging potential consequences,” he says.

I agree that if you try to reduce sunlight for the whole atmosphere by spreading Aerosols you could end up with some undesirable results. We’re already experiencing disturbances in weather patterns because of warming and the melting of the Arctic. My proposal would take longer to implement but the reflecting of sunlight could be more easily controlled. It could be done just by make adjustments to the positioning and angle of the components. As I said in the post, you probably would want to situate the solar shield so that it reflects sunlight hitting one of the polar areas. They heat up much faster and they get more sunlight so the solar shield would have a much larger effect. It would be less like turning down the heat and more like moving pot so that part of it isn’t directly over the heat. You can easily experiment with this. Fill a sauce pan with water. Heat it on the stove (low or medium heat). Use a thermometer to test the temperature. When the temperature reaches the maximum possible move the pan so that about 3rd of the bottom surface area is not directly over the heating source. Wait a few minutes and take more temperature readings. This time take a reading in the center, the side closest to you and the side farthest away. If my hypothesis is correct then the water not directly over the heat source should cool down a bit and probably will reduce the average temperature of all the water a bit (after sometime being situated this way).

Another article suggest that a solar-shade could be beneficial

New research led by Carnegie’s Julia Pongratz examines the potential effects that geoengineering the climate could have on global food production and concludes that sunshade geoengineering would be more likely to improve rather than threaten food security. Their work is published online by Nature Climate Change Jan. 22.

Sometimes you have to increase the complexity of the engineering task and experiment with it in different ways to get the optimal results. I wouldn’t expect that even if the solar shield is built that we’ll return to the same climate of the previous century. By cooling the polar region(s) it might have a stabilizing effect on the weather patterns. I don’t see how anything we might do could result in returning an earlier climate situation in our history.

Geoengineering Approaches to Reduce Climate Change Unlikely to Succeed

Climate Change: Beating around the bush won’t put out the fire

Graham Wayne is correct. We need to act to confront climate change and the sooner the better.

Small Epiphanies

There is just one reason we’re failing to address climate change. It isn’t discussed much. Nobody wants to hear about it. Nobody wants to confront it. Nobody wants to acknowledge the fundamental nature of the challenge. Yet we’re all edging closer and closer to unthinkable answers, no matter how hard we try to avoid asking the unthinkable questions.

We need to develop a plan for dealing with sea level rise

Peter Sinclair posted this video on his blog. It has some troubling new information.

We need to develop an action plan to deal with the likely outcome that about 10% of the world’s population will eventually be displaced. Ideally, before it happens. It does happen slowly so there is time to come up with some ideas. The trick will be getting the other 90% to care about those affected by it enough to contribute to finding solutions. The main driver of sea level rise is climate change. Solve that and you could save the lives and property of millions of people around the world.

An idea for dealing with the problem directly would be not encouraging new development along coastlines unless it meets high standards for safety and resiliency. New homes would need to be raised up enough to not be as vulnerable to flooding, and be able to withstand hurricane force winds with ever greater intensity.

This is how climate deniers respond to climate leadership

One of my Facebook friends, Larry Lazar, wrote an excellent Op-Ed for It was called Something in the weather tells us climate change is real pointing out that the weather has changed and this is because of man-made climate change.

This is how a Mel Herr of Webster Groves responded:

Regarding “Something in the weather tells us climate change is real” by Larry Lazar (Nov. 27):

Hey, Larry, wake up and smell the coffee. Very few people are challenging climate change! What we challenge is your assumption that it is man-made. The earth has always had climate change, and now is no different.

I’m sure your old pa and his anecdotes about how cold it used to be are very entertaining. I know my dad used to tell me about walking 6 miles to school in knee-deep snow and it was uphill both ways. The fact is we only remember the exceptions and not the rule. Ask him to remember all the winters that were average, or not as cold, or a little dry. Believe me, there were far more of them than the extreme ones he remembers.

Finally, Larry, since you know everything dealing with climate change is man-made, then tell the people in the rest of the world to stop burning coal or wood just to survive the winter. Or tell the termites to stop emitting methane, by the way another more potent greenhouse gas. Or how about the volcanoes emitting millions of tons of the same gasses you’re trying to curb? So if you want to do your part in solving the problem, stop procreating. Remember the fewer of us the better for good old Mother Earth.

There are numerous indicators that Larry Lazar is correct and only someone is in denial wouldn’t see that is us that is doing it to ourselves.

Mel and climate deniers like him need to Wake up. Your life and the lives of your children are at stake here. You should be doing everything you can to make sure that your children have a livable environment well into the future.
