Arctic sea ice / Re: The 2017 melting season
« on: July 19, 2017, 12:01:08 PM »
2016 was hottest or second hottest on record across the arctic from Sep to  Dec and in the top  5 from June - Aug.  This year is unlikely to be anywhere near that hot and I would expect  the October peak to be much closer to  normal than last year.
Have you taken into consideration how there has not been any growth to speak of in 2017? There has not been one month of 'normal' ice since about mid September 2016. So if 2017 would have to pick up in being cold enough for new ice, it sure is taking long..

"If FF demand is significantly down do you think is in FF producing companies interest to adapt or to be in denial?"

Denial, absolutely.  They are hell-bent on razing as much of the environment as they can, to make as much money as they can, in the few years they have left.  They are "adapting" even more slowly than the legacy auto makers, who at least have a clear path forward via EVs.

Edit:  They've known this day was coming for over 50 years.  And yet still deny it -- outwardly, anyway!

Every government the last 50 yrs or more in US Europe and Russia were equally knowledgeable...

Here is an article I find more disturbing than the Wallace-Wells piece. It shows there hasn't been a leveling of oil or gas use there has been a continued increase. It also shows the downturn in coal may be far smaller than that reported because, as we have discussed here on the ASIF , Chine has been under reporting.

Since we sometimes ;) fault clean energy companies for being overly optimistic about the rise of renewables, I think it is appropriate to be a little skeptical of fossil fuel data from BP.  If they were to report that FF use was declining significantly, it could set off a global financial oil panic. 

For example, they forecast only 5 to 6% of cars will be electric in 2035.

We now have more detailed data on CO2 from satellites.  But that only shows total CO2, earth and human-caused, so that's not yet the answer.

If we were to have "proof" of CO2 emissions by region, I wonder what the response would be.  Denial?  Anger?  War?

Paranoid little? BP's graphs are based on publicly available data. They are not 100% or even 90% accurate but your paranoia that they are fudged is a little too much. There are monthly and weekly and daily reports of primary energy use that would have shown a significant slowdown in your scenario much faster than the annual updated BP report.

If FF demand is significantly down do you think is in FF producing companies interest to adapt or to be in denial?

Getting us all to accept the hardships that zero is going to result in requires some knowledge of the climate system and the carbon cycle.

I see no hope in getting almost all people concerned about climate change early enough to avoid extreme climate change.  Look at the number of people in the world who misuse alcohol, tobacco and other addictive drugs.  Or who are badly overweight.  Or drive recklessly.  Those people are doing stuff that they know will almost certainly harm themselves, sometimes soon.  People just aren't going to make changes because of something that might get nasty 100 years from now. 

We have to find replacements that are as good/better and cost no more/are cheaper.  Hopefully, better and cheaper.

I see no hardships when it comes to electricity, heating, and transportation.  The replacements we have now are 'better' and cheaper.  It's just a matter of switching over.  And as we go along our replacements are very likely to get even better and even cheaper.

I haven't dealt with ag emissions.  I tend to try to stay focused on energy and transportation.

I'm not really worried about feeding our increasing population.  We can do that by cutting waste and improving ag techniques in our least productive fields.  That's not to say that we won't see a lot of hungry/starving/dying people along the way.  We tend to fix problems after they happen rather than before.  (I suspect the massive famines we've seen in the past are now no longer going to occur due to improved communication and transportation.  Problems will be more localized because of distribution problems.)

Meat and dairy are our largest food-carbon problems, I think.  We can farm with electricity and biofuels.

I'm hopeful that factory grown meat will turn out to be cheaper than hoof-raised which should greatly solve the methane belch problem.  And turning meat grazing land into forest or other carbon sink land might cancel out dairy problems.

The ag solutions have to be 1) as good as what we now eat and 2) as cheap or cheaper.  I don't think we can legislate away meat consumption on a worldwide scale until after it's too late and the globe is in a panic.

Sorry for the OT but being overweight is not equivalent to driving recklessly or even being one's choice.  Poor people's access including their ability to buy healthy food is limited to the point that they cannot escape a vicious downard spiral.

From the China thread:

Six Million People in China Just Went 100% Renewable for a Week
It's the first major test of renewable energy on the grid in China.
“Clean energy is the ultimate way,” Han Ti, general manager of the Qinghai grid company told local news outlet Xinhua. “We need to reduce reliance on fossil fuel, improve our energy structure, and reduce carbon emissions.”

The Qinghai province has 19.7 million kW of renewable energy installed, and makes up a little over 82 percent of all the energy production in the province. Qinghai is the fourth largest province in China, spanning the northeast part of the Tibetan plateau and has the headwaters of the two largest rivers in China, the Yellow and Yangtze Rivers. Most of the energy during the test week was produced by hydro-electric power, thanks to the major rivers. Because of its renewable energy output, and the fact that it is one of the most sparsely populated regions of China, it is the ideal place to test the using only green energy.

>70% Hydro.  Worth mentioning...

Tesla is paying for the deployment of destination AC chargers that all EVs can use
Tesla operates two different charging networks. While Tesla’s Supercharger network is made of DC fast-charging stations for long distance driving, the Destination Charging network consists level 2 chargers, more specifically the ‘Tesla Wall Connector’, installed at restaurants and hotels to charge once Tesla owners arrive at their destination, hence the name.

As we already knew, the company supplies those chargers for free, officially 2 chargers, but we’ve heard of busy locations where Tesla supplied more, including covering the cost of the installation.
Electrek has talked to several business owners with Destination Chargers and some of them revealed that Tesla suggested them to install a Clipper Creek Charger, along with the Tesla Wall Connector, at no additional cost.
The total cost of those installations can easily add up to several thousands of dollars after all the equipment and installation. Yet, Tesla doesn’t even have a formal contract with the business owners – only a letter of intent to confirm that the automaker will cover the cost of chargers and the installation, while the host will cover the electricity bill....

Tesla is putting the rest of the car industry in a position where they will either have to up their game or cede more and more market to Tesla over time.

Tesla is likely to end up with the lowest manufacturing cost for a similar sized/featured EV due to their highly automated battery and vehicle factories.  Tesla isn't having to sell wholesale and let independent dealers take a cut.  As long as Tesla maintains quality while offering better charging opportunities a large portion of the EV market is likely to buy a Tesla.

How long can Tesla afford keep losing money....

Arctic sea ice / Re: The 2017 melting season
« on: June 22, 2017, 12:28:09 PM »
If such a big cyclone gets followed by high pressure and then another cyclone, things might really start to look like Mike Tyson in his prime.
You mean beaten? Or biting? =)


I imagine rain is far better , and faster, at melting ice than sunshine?

I think if you have 2 blocks of ice , one sat in water in shade but under a constant shower of water and one sat in water in full sun the heat transfer from the constant rain would be greater than the sunshine?
Depends on how much rain it is. It takes LOTS of energy to make the solid-to-liquid transition, - basically same amount of energy per gram as it takes to increase temperature of that gram of water from 0C to 83C. So, let's say rain water comes in at some 5C temperature; then to melt roughly 1 cm of ice thickness, we'd need roughly 16 cm layer of water from such "+5C" rain water to fall. 1 meter of thickness = 16 meters of rainfall. The latter's quite unrealistic, don't you think.

It is not rainfall directly which spells doom for ice; it's related effects which the cyclone produces.

1st, winds cause wave action, steering water column of the ocean - and there is HUGE amount of heat, in most places, stored in that "mixable by strong cyclone" 100 meters water column. Easily enough to melt a meter of ice on the surface.

2nd, rain creates ponds and destroys any remaining snow cover easily, and so after cyclone is gone, much reduced albedo of ponded ice allows sun to melt things times faster.

3rd, whereever ice is in much broken shape already, waves will break it further into smaller pieces, thus increasing total surface of water-ice boundary - and summer-time this can only mean faster melt whenever any warm wind and/or more rain and/or more sunshine and/or warm water current would come next.

Rain freezing on ice is what gives the energy...

Hydroelectric dams may jeopardize the Amazon's future

Hundreds of built and proposed hydroelectric dams may significantly harm life in and around the Amazon by trapping the flow of rich nutrients and modifying the climate from Central America to the Gulf of Mexico. These findings, published in Nature, emerge from a multidisciplinary, international collaboration of researchers from 10 universities, led by scientists at The University of Texas at Austin.

To meet energy needs, economic developers in South America have proposed 428 hydroelectric dams, with 140 currently built or under construction, in the Amazon basin—the largest and most complex network of river channels in the world, which sustains the highest biodiversity on Earth. The rivers and surrounding forests are the source of 20 percent of the planet's fresh water and valuable ingredients used in modern medicine.

While these hydroelectric dams have been justified for providing renewable energy and avoiding carbon emissions, little attention has been paid to the major disturbances dams present to the Amazon floodplains, rainforests, the northeast coast of South America and the regional climate, the researchers said.

Slightly off-topic, but it looks like Global sea ice area could hit a record low maximum soon, beating last year (graph from Wipneus):

I hope the global sea ice budget does not enter a new phase ( following last year's trajectory ) - the global albedo will see a step change.

My interpretation is that ice which is thinning by bottom melt is pushed below the surface by its snow load. The snow is melted away by seawater from the floe edge inward. That the snow does not disappear quickly as soon as the ice sinks must be due to low air temperatures.
Does this make sense? 

The snow does not melt because the seawater is not warm enough to melt it.  It just sits there.  Until the seawater temperature rises above 0C it can't melt the snow.
a snowball in salt water will melt through mixing and diffusion (osmotic pressure) even below 0C

Peak Solar is around midday, peak wind is early in morning and evening. You need both on the grid to maximize output. As a system ( solar + wind ) they will have a system or combine service factor. Actual capacity = Nominal capacity x service factor.

Is deep sea mining vital for a greener future, even if it destroys ecosystems? “Mining will be the greatest assault on deep-sea ecosystems ever inflicted by humans”

(The Guardian) – Mining the deep ocean floor for valuable metals is both inevitable and vital, according to the scientists, engineers, and industrialists exploring the world’s newest mining frontier.

The special metals found in rich deposits there are critical for smart electronics and crucial green technologies, such as solar power and electric cars. But as the world’s population rises, demand is now outstripping the production from mines on land for some important elements.

Those leading the global rush to place giant mining machines thousands of metres below the sea surface say the extraordinary richness of the underwater ores mean the environmental impacts will be far lower than on land. But critics say exotic and little-known ecosystems in the deep oceans could be destroyed and must be protected...

Domes of frozen methane may be warning ch for new blow-outs

Several methane domes, some 500m wide, have been mapped on the Arctic Ocean floor. They may be signs of soon-to-happen methane expulsions that have previously created massive craters in a near-by area...

"Every year we go back to the dome area with our research vessel, and every year I am anxious to see if one of these domes has become a crater," says lead author of the study Pavel Serov, PhD candidate at CAGE at UiT The Arctic University of Norway.

These domes are the present-day analogue to what scientists think preceded the craters found in the near-by area, which were recently reported in Science. The craters were formed as the ice sheet retreated from the Barents Sea during the deglaciation some 12.000 years ago.

Temperature Swing Adsorption  (using steam or external heating for CO2 description). Commercial indeed. Nonetheless rather expensive for large scale commercialization ( cost per kg CO2 captured). I guess they use the waste heat from the incinerator. Would be better to capture the CO2 directly from the flue gas of the waste incinerator.

Homeless Gasoline Tankers Are Drifting Around the Caribbean
At least three large ships awaiting delivery instructions
A few gasoline cargoes around the Caribbean Isles are looking for homes.

Three tankers holding about 1.35 million barrels of gasoline and alkylate, an octane-boosting component blended with motor fuels, are drifting with no instructions for delivery. The cargoes came from India with intent to land in the U.S., but now they’re in limbo as traders from Trafigura Group Ltd. and Mercuria Energy Group Ltd. shop around for the best selling value in the region.
“My sense of it is these may be barrels that end up in Venezuela,” Robert Campbell, head of oil products research for Energy Aspects, said by phone from New York. “They tend to bring in alkylate.”

Supplies are dangerously low in Venezuela, he said, and most of the country’s fluid catalytic cracker units that make gasoline are out of commission. Two gasoline tankers from Europe were diverted to Venezuela this week after state-owned Petroleos de Venezuela said it would boost imports after a traffic-stopping shortage in Caracas last month.

There is large need for Diesel from US refineries. As a result there is a growing glut of gasoline in US and I guess those barrels in the tankers need to find a new home. Probably are changing hands and getting traded among companies trying to maximize margins. Soon shipping costs will force the holdings companies to unload the cargo somewhere..

I get your point, but right now I don't think Venezuela is exporting oil.  At times during the last year it looks like they've been oil importers.

But if a war broke out between some of the lower cost producers Venezuela and other more expensive producers could come back into the market, driving prices up.

They imported light fractions to use as diluent for their heavy oil.

From : "LCA of pellet burning technologies" by Thomas Willem de Haan

Pellets as a heating fuel in domestic appliances can be considered as a low carbon fuel, relative to the alternative fossil fuels. The emissions of a pellet heating system can be as low as 6,04 g CO2/MJ whereas its least polluting fossil counterpart emits 62,8 g CO2/MJ. If the pellets are being transported overseas, the CO2 emission would amount to 27,7 g CO2/MJ. This is still less than half the figure for the lowest fossil heating fuel but the most optimal use of pellets is for application on a local scale. The most influential parameters are the management of the forest the used wood is taken from and the transportation of the pellets. All the calculations are based on the premise that the harvested wood is regrown. As long as the wood is being harvested in a sustainable way, the low net CO2 emission as determined in this paper can be achieved. It should be emphasized, however, that sustainable harvesting is absolutely necessary to maintain the delicate balance.  Another conclusion to be drawn from this study is that the transportation of sawdust pellets over long distances has considerable impacts. Nevertheless, even transatlantic transported pellets have a lower net CO2 emission than heating with fossil fuels.

From Climate Central: Europe’s Farming Vulnerable with Water Scarcity

Water scarcity half a world away caused by climate change could push up prices for meat and diary products in Europe by disrupting supplies of soybean, which is widely used as feed for livestock, researchers said Wednesday.

The European Union sources most soybean from outside the 28-nation bloc — mainly from Argentina, Brazil and the United States, according to an EU-funded study by Dutch-based NGO Water Footprint Network (WFN).

But 57 percent of soybean imports are from regions that are highly vulnerable to water scarcity, exposing Europe to possible shocks in supply, said Ertug Ercin, the study's co-author.

"The highest risk that the European meat and dairy sector will face due to climate change and weather extremes lies outside its borders," he said in a statement.
