Justin Gillis answer to  Question 5. Will reducing meat in my diet help the climate?

Yes, beef especially.

Agriculture of all types produces greenhouse gases that warm the planet, but meat production is especially harmful – and beef is the most environmentally damaging form of meat. Some methods of cattle production demand a lot of land, contributing to destruction of forests; the trees are typically burned, releasing carbon dioxide into the atmosphere. Other methods require huge amounts of water and fertilizer to grow food for the cows.

The cows themselves produce emissions of methane, a potent greenhouse gas that causes short-term warming. Meat consumption is rising worldwide as the population grows, and as economic development makes people richer and better able to afford meat.

This is worrisome: Studies have found that if the whole world were to start eating beef at the rate Americans eat it, produced by the methods typically used in the United States, that alone might erase any chance of staying below an internationally agreed-upon limit on global warming. Pork production creates somewhat lower emissions than beef production, and chicken is lower still. So reducing your meat consumption, or switching from beef and pork to chicken in your diet, are both moves in the right direction. Of course, as with any kind of behavioral change meant to benefit the climate, this will only make a difference if lots of other people do it, too, reducing the overall demand for meat products.

My answer to  Question 5. Will reducing meat in my diet help the climate?

It will do very little for the climate, but it might help your personal economy to switch your eating habits. Beef used to be cheap, but no more. Bacon, baby pork ribs, beef tenderloin, veal cutlets, chicken wings are at premium prices, and switching from beef to chicken and turkey is already under way thanks to the wonderful regulator called the free market. However, there is one thing that will help the environment and indirectly the climate:

Switch from feed-lot beef to grass fed beef. Release more grasslands for responsible grazing to preserve the environment. Here is an interesting video:

A Climate Realist’s (not so) short Answers to Hard Questions About Climate Change. Question 4 (of 16) What’s the optimistic scenario?

Answers to Question 2. How much trouble are we in?

Answers to Question 3. Is there anything I can do?

Justin Gillis answer to Question 4. What’s the optimistic scenario?

“Several things have to break our way.

In the best case that scientists can imagine, several things happen: Earth turns out to be less sensitive to greenhouse gases than currently believed; plants and animals manage to adapt to the changes that have already become inevitable; human society develops much greater political will to bring emissions under control; and major technological breakthroughs occur that help society both to limit emissions and to adjust to climate change.

The two human-influenced variables are not entirely independent, of course: Technological breakthroughs that make clean energy cheaper than fossil fuels would also make it easier to develop the political will for rapid action.

Scientists say the odds of all these things breaking our way are not very high, unfortunately. The Earth could just as easily turn out to be more sensitive to greenhouse gases than less. Global warming seems to be causing chaos in parts of the natural world already, and that seems likely to get worse, not better. So in the view of the experts, simply banking on a rosy scenario without any real plan would be dangerous. They believe the only way to limit the risks is to limit emissions.”

My answer to Question 4. What’s the optimistic scenario?

We are now in a sweet spot as to climate, not too warm and no ice age yet. Were it not for increasing CO2 levels the little ice age might have triggered the onset of a real ice age, but a lot of factors, such as coming out of the Maunder solar minimum, starting industrialization in England and Germany sooting up the growing glaciers so they started melting again, the diminishing effect from the Tycho Brahe and Kepler supernovas cosmic radiation, all contributed to get us out of the start of the new ice age. Yet, we are into the latter stages of the bog generating phase of the interglacial period, and the onset of a new ice age is overdue.

We need more CO2, not less to keep us in the climate sweet spot. Increasing CO2 levels to between 850 and 1000 ppm should delay the onset by about 2000 to 5000 years (my guess), but after that the next ice age is coming. Historically, according to the Milankovitch cycles we should have already entered the next ice age.

This picture is simplified, but together with the other cycles the picture is quite complicated.

The take home from this picture is that daily insolation (at the 60th latitude) can vary by as much as 100 w/m2 or about 50 times the effect of a doubling of the CO2 level. It is also worth noting that the normal state of the earth is ice age, and thermal runaways have never occurred, even when in past geological ages, CO2 levels were over 10000 ppm.

A Climate Realist’s (not so) short Answers to Hard Questions About Climate Change. Question 3 (of 16) Is there anything I can do?

NOV. 28, 2015 gave his answers to 16 questions in the N.Y. Times regarding Climate Change. This Climate realist added his answer.

 Answers to Question 1: How much is the planet heating up?

Answers to Question 2. How much trouble are we in?

Justin Gillis answer to Question 3. Is there anything I can do?

Fly less, drive less, waste less.

You can reduce your own carbon footprint in lots of simple ways, and most of them will save you money. You can plug leaks in your home insulation to save power, install a smart thermostat, switch to more efficient light bulbs, turn off the lights in any room where you are not using them, drive fewer miles by consolidating trips or taking public transit, waste less food, and eat less meat.

Perhaps the biggest single thing individuals can do on their own is to take fewer airplane trips; just one or two fewer plane rides per year can save as much in emissions as all the other actions combined. If you want to be at the cutting edge, you can look at buying an electric or hybrid car, putting solar panels on your roof, or both.

If you want to offset your emissions, you can buy certificates, with the money going to projects that protect forests, capture greenhouse gases and so forth. Some airlines sell these to offset emissions from their flights, and after some scandals in the early days, they started to scrutinize the projects closely, so the offsets can now be bought in good conscience. You can also buy offset certificates in a private marketplace, from companies such as TerraPass in San Francisco that follow strict rules set up by the state of California; some people even give these as holiday gifts. Yet another way: In states that allow you to choose your own electricity supplier, you can often elect to buy green electricity; you pay slightly more, with the money going into a fund that helps finance projects like wind farms.

In the end, though, experts do not believe the needed transformation in the energy system can happen without strong state and national policies. So speaking up and exercising your rights as a citizen matters as much as anything else you can do.

My answer to Question 3. Is there anything I can do?

First let us look at the so called carbon footprint. These feet are from 2010.

I would like to acknowledge Stanford Kay Studio; a version of this graphic first appeared in Miller-McCune. Thank you, Stanford! Copyright Stanford Kay 2010. China has the largest carbon footprint in the world, followed by the United States, but when it comes to carbon footprint per capita Gibraltar is number one, followed by the U.S Virgin Island.  How can that be? Everything in Gibraltar must be imported, and nearly everything is imported to the U.S. Virgin Islands.

The solution to lower the carbon footprint is to produce and buy local, and eat things produced in season.

Pipelines has less than half the carbon footprint of the same substance transported by rail.

Transport by rail has much smaller carbon footprint than transport by truck.

Electric cars make no sense as long as electricity is produced by fossil fuels. The extra energy consumed in manufacturing the batteries will never be repaid if transmission and conversion losses are taken into account.

Make food from scratch rather than eating processed food.

If possible plant a garden and eat fresh vegetables. Even a window pot with chives makes the sour cream tasty. A rosemary pot is wonderful. I could wax eloquent, but you get the point.

Don’t ever buy CFL light bulbs again, and don’t throw the old bulbs in the trash. Sometimes in the future we will have to mine the landfills.

A lot of stuff is flown in from abroad, very energy inefficient. Work to make it locally.

A Climate Realist’s not so short Answers to Hard Questions About Climate Change. Question 2 (of 16) How much trouble are we in?

NOV. 28, 2015 gave his answers to 16 questions in the N.Y. Times regarding Climate Change. This Climate realist added his answer.

 Answers to Question 1: How much is the planet heating up?

Justin Gillis answer to Question 2. How much trouble are we in?

“For future generations, big trouble.

The risks are much greater over the long run than over the next few decades, but the emissions that create those risks are happening now. Over the coming 25 or 30 years, scientists say, the climate is likely to resemble that of today, although gradually getting warmer. Rainfall will be heavier in many parts of the world, but the periods between rains will most likely grow hotter and therefore drier. The number of hurricanes and typhoons may actually fall, but the ones that do occur will draw energy from a hotter ocean surface, and therefore may be more intense, on average, than those of the past. Coastal flooding will grow more frequent and damaging.

Longer term, if emissions continue to rise unchecked, the risks are profound. Scientists fear climate effects so severe that they might destabilize governments, produce waves of refugees, precipitate the sixth mass extinction of plants and animals in Earth’s history, and melt the polar ice caps, causing the seas to rise high enough to flood most of the world’s coastal cities.

All of this could take hundreds or even thousands of years to play out, conceivably providing a cushion of time for civilization to adjust, but experts cannot rule out abrupt changes, such as a collapse of agriculture, that would throw society into chaos much sooner. Bolder efforts to limit emissions would reduce these risks, or at least slow the effects, but it is already too late to eliminate the risks entirely.”

My answer to  question: 2. How much trouble are we in?

For climate alarmists: big trouble, for climate realists, not anything out of the ordinary as to temperature rise.
The temperature rise is predicted using models that assume the major effect on the climate is from rising CO2 and ignore other factors such as a changing cloud cover. The imbalance due to rising CO2 levels is less than 2W/m2, and every percent change in cloud cover makes a larger difference. Here is the performance of 73 climate models versus observations.
There is almost no correlation between models and observations. What is the problem? Looking at how the models model clouds gives a hint:The models are way off on the amount of clouds. Antarctica is almost cloud free and the Arctic has plenty of clouds. This means the models totally underestimate the effects of water vapor (the source of clouds) and overestimate the effects of rising CO2.  It turns out that clouds are the major stabilizer of the climate on the high end, thanks to their high negative feedback – more clouds, cooler climate. This means that even with a doubling of the CO2 levels we will not even get back to even the Medieval warm period. We are in a long cooling trend.
No such feedback occurs when it cools, rather more snow means higher albedo which leads to a new ice age. More CO2 will delay the onset of the next ice age, but will not prevent it. Fear not, the next ice age is probably more than 5000 years away.

A Climate Realist’s not so short Answers to Hard Questions About Climate Change. Question 1 (of 16) How much is the planet heating up?

1. How much is the planet heating up?

As of February 2016, the Earth has warmed about 1.8 degrees Fahrenheit since 1880, when records began at a global scale. That figure includes the surface of the ocean. The warming is greater over land, and greater still in the Arctic and parts of Antarctica, but there is very little warming in the tropics.

Since pre-industrial times the CO2 level has increased from 280 ppm to 405 ppm, an increase of about 45%, and we know that for every doubling of CO2 temperatures will rise about 1.6 degrees F unless other factors dominate, such as positive or negative temperature feedbacks.

During ice-ages global temperatures hover around 10 degrees F colder with CO2 levels around 185 ppm. Global temperature was about 6 degree F colder than today and in about 4000 year time temperature rose rapidly and we came out of the ice age. During that time, and with a 300 to 800 year delay CO2 rose from 185 ppm to 265 ppm, a 43% rise.  Coming out of the ice age, if CO2 was the only factor,  the effect of doubling CO2 would increase global temperatures by 11.5 degrees F.

Al Gore saw the charts, and got so alarmed that he wrote “Earth in the balance.” What he didn’t take into account was that the major rise in temperature was not due to the increasing CO2, but the loss of albedo when the ice melted. CO2 played a supporting role, a lagging one. Then, around 9000 years ago temperatures stopped rising, CO2 levels stabilized and we entered a period of relative stability. What happened?

The albedo came back, this time in the form of increasing clouds. Once the oceans got warmer and stabilized, there was enough water vapor in the air to make more clouds, and so stabilize temperature. Since then temperatures have been on a slow decline, and the trend was accelerating until the ” little ice age”. There were 3 notable warming periods, the Minoan, the Roman, and the Medieval warming period.

During the Roman warm period wine grapes were grown almost up to the Hadrian Wall. It is well documented, and in Northhamptonshire, England there were at least 9 flourishing wineries..

The Roman Northamptonshire wine
was good, not excessively fine.
So it just goes to show
that Al Gore does not know
of Climate Change past, that’s my line.

The the dark ages came and grapes no longer ripened in England. During the Medieval Warm Period there was at least one cheese farm on Greenland “Gården under sanden”, abandoned as the glaciers regrew, starting the “Little Ice Age”. During the little ice age it got so cold, that in Jan 1658 the Swedish army crossed the Great Belt of Denmark over ice, canons and all,  and sacked Copenhagen. We are still recovering from the “little ice age.” 2016 may have been a warm year, but most years since the ice age were warmer. See Chart.Greenlandgisp-last-10000-newWe are still in the sweet spot of a remarkable stable Climate, only more CO2 will save us from a new Ice Age. We are not yet back to the Medieval warming period, much less the Roman and even less the Minoan. A doubling of CO2 will not get us back to the Roman warming period since the negative feedback from clouds will dominate and limit the temperature rise.

As to the fear mongering claim that “The heat accumulating in the Earth because of human emissions is roughly equal to the heat that would be released by 400,000 Hiroshima atomic bombs exploding across the planet every day,” I can only say that the energy from the sun is equivalent to over 25oo Hiroshima bombs per second, or about 540 times as much as comes from human energy production, about 0.2%, hardly anything to worry about.

Change of tune in next week’s G20 meeting on Climate Change, a Limerick.

G20 to meet in Black Forest

Sweet unity  no longer chorused

The encouraging word

in the Paris accord

Mnuchin to farce metamorphosed.

(Bloomberg) — Finance ministers for the U.S., China, Germany and other members of the Group of 20 economies may scale back a robust pledge for their governments to combat climate change, ceding efforts to the private sector.

Citing “scarce public resources,” the ministers said they would encourage multilateral development banks to raise private funds to accomplish goals set under the 2015 Paris climate accord, according to a preliminary statement drafted for a meeting that will be held in Germany next week.

The statement, obtained by Bloomberg News, is a significant departure from a communique issued in July, when finance ministers urged governments to quickly implement the Paris Agreement, including a call for wealthy nations to make good on commitments to mobilize $100 billion annually to cut greenhouse gases around the globe.

“It basically says governments are irrelevant. It’s complete faith in the magic of the marketplace,” John Kirton, director of the University of Toronto’s G-20 Research Group, said in an interview. “That is very different from the existing commitments they have repeatedly made.”

The shift in tone comes as U.S. President Donald Trump’s Treasury Secretary, Steven Mnuchin, prepares for his first G-20 meeting, scheduled for March 17 to 18 in the spa town of Baden-Baden. While European nations including Germany have been at the forefront of combating global warming, Trump has called climate change a hoax.

The Republican president vowed during his campaign to “cancel” the Paris agreement but has said little about the deal since taking office. His cabinet members, meanwhile, have sent mixed signals. U.S. Secretary of State Rex Tillerson said the U.S. should keep a seat at the table for international climate talks. Scott Pruitt, the head of the Environmental Protection Agency, on Thursday expressed doubt that humans were to blame for global warming and called the Paris agreement a “bad deal” for the U.S.

The most notable element of the draft is what’s missing. The statement issued after the G-20 finance ministers and central bank governors meeting in July dedicated 163 words to the Paris Agreement, pushing nations to bring the deal into force, meet emissions targets and fulfill financial pledges. This current draft dedicates just 47 words to the agreement, focusing exclusively on development banks raising private funds, without mentioning government financial support.

Germany, as the meeting’s host, leads the process of writing the statement, which will eventually be adopted via consensus by all 19 nations plus the European Union. The German finance ministry declined to comment on the draft.

“The most charitable thing to say is they’re waiting to see where Donald Trump actually lands by the time they get in Hamburg and thus, doing nothing to annoy the incoming American Treasury Secretary,” Kirton said.

German Chancellor Angela Merkel, who holds the rotating presidency of the G-20, has signaled that she would use the forum to push Trump on climate issues. The two leaders are scheduled to meet in Washington March 14.

“The takeaway is it clearly puts less emphasis on climate finance as a priority than last year’s did,” Alden Meyer, director of policy at the Union of Concerned Scientists, said in an interview. “It doesn’t talk about government action. That is a significant step back from what countries agreed to in Paris.”

Greenpeace protest got fertilized. A Limerick.

Aroma from countryside Lancashire;

the farmer gave Greenpeace its hire.

Emma Thompson got sprayed

she got frackin’ afraid.

Her bake-off, frack free, reeked of mire.

Source, The Telegraph: An angry farmer attempted to spray Oscar-winning actress Emma Thompson with manure on Wednesday after she broke a court injunction to stage a protest against fracking on his land. Ms Thompson and her sister Sophie entered a field on the Lancashire farm, where energy company Cuadrilla is planning to frack for shale gas, and baked renewable energy-themed cakes in a Greenpeace-backed protest stunt. An injunction has been in place banning protesters from the land near Preston since 2014 .The farmer, who was said to be “very upset” about being prevented from getting on with work in the field, proceeded to drive a muck-spreader around the protesters, narrowly missing the Thompson sisters and their cakes. Emma Thompson said she was staging the so-called “Frack Free Bake Off” in order to “show the government that we will not allow fracking to scar our countryside and fuel yet more climate change”.  “What better way to do that, here in Britain, than hold a Bake Off?,” she asked.

 

 

 

 

 

More trouble for Oroville Dam, a Limerick.

More trouble for Oroville Dam

Debris caused a water log-jam

Got a week-long reprieve

to remove the debris.

A scene of increasing bedlam.

The Oroville Dam is in more trouble than thought. Between one half and one million cubic yards of debris is clogging up the diversion pool causing the power plant to be shut down until it is cleared. The debris is all from erosion from the failing spillways which shows the erosive power of water not properly channelled. In addition they continue work on the emergency spillway and will attempt to shore up the breach in the main spillway.

920x1240It is a race against time. The upstream dams are all full, so all the snow-melt will fill the Oroville Dam back in no time, and there is at least one more major rain event coming down the pineapple express. The snow-pack is already way over normal for the season, so both spillways will have to be used again, and soon.

Will they succeed with the task in time?

Keep the bags packed if you live downstream. And please, pray!

The Moffat tunnel, Continental theft of water. A Limerick

What flows through the tunnel of Moffat?

It’s water for Denver’s own profit.

When South-West tries to sue.

Will they win, get their due?

I never was much of a prophet.

The Moffat tunnel in Colorado, built in 1928 is a six mile railroad and water  tunnel that goes under the continental divide. The water tunnel carries up to 105 acre-feet of water per hour to the City of Denver. The water is taken from the Colorado river watershed, which leaves the South Western states with nearly one million acre-feet less water per year.

When the tunnel was built this was not much of a problem, Nevada had less than 100, 000 inhabitants, Arizona less than 350,000 and California about 3.5 million people. Now Nevada has 25 times as many people, Arizona 15 times as many , and California 10 times as many people, all thirsty for more water.

It is time to stop robbing the South-west of water. Yes Denver has its own water problem, but the South West has much greater problem.

Lake Mead water level is now 140 feet below full capacity, and has been dropping about 10 feet per year, and will run dry unless drastic measures are taken. The Moffat tunnel takes away about 6 feet a year from the filling of Lake Mead.

Yes, thanks to this year’s rain, Lake Mead has recovered somewhat, but the long trend is still ominous.

And by the way, this has nothing to do with Climate Change.

Lake Oroville dam in more trouble. A Limerick.

Lake Oroville fills up again

Ten trillions more gallons of rain

Will the spillway give way?

It’s too early to say,

while permanent drought fears remain.

In 2005 environmental groups and structural engineers pointed out that the emergency spillway was in dire need of being reinforced, or the whole dam would fail if it was ever used. The claim was ignored, but the stimulus package of 2009 was looking for shovel ready projects, so  more than 32 million dollars was offered for dam repairs, but the Sacramento politicians chose instead to use some of that money on beautification of side-walks and a set of bike-ways for the University of California. Thanks to Climate change the spillway would never be used, and California was entering a state of permanent drought.

So much for spending billions of dollars of climate change research. A quick look at the flood of 1862 would have given them reason to keep the dams in good repairs. Now the cost of repairing Oroville Dam will run into hundreds of millions of dollars.

If a new event like 1862, the total cost to California could be up to 700 Billion dollars, part of that due to failing dams,  unless the dams are reinforced and properly maintained. The rain damage may be bigger than the damage from “the next big earthquake” another sure thing.

Meanwhile, due to debris, the 835 MW power station is out of commission, so all the water has to go down the spillway rather than generating electricity. Lake Oroville Dam has the ideal peak power plant, so they lose more than a million dollars a day in revenue as well.

California is in big trouble, and the politicians are still sticking their heads in the sand hoping it will not happen on their watch.
