Policy and solutions / Re: Policy and solutions in the Netherlands
« on: November 26, 2019, 04:19:26 PM »
The problem with the pigs isn't only the CO2, but also nitrogen which pollutes our (human-planned...) nature. Almost all pigs produced in those large farms are for the export and probably also with european subsidy. So f.e. China buys our cheaps pork meat, we have the pollution and pay for it also by subsidy's.

The heating should be done by heat pumps. I think the idea is that heat pumps are more efficient than burning fossil fuels, because you also need better isolation. And burning fossil fuels in large plants is most of the time more efficient than doing it at home.

Policy and solutions / Re: Policy and solutions in the Netherlands

Well, in the Netherlands we are going off-grid with gas.

If I remember correctly since a couple of years it isn't obligated anymore when building a new houses to connect it to the gas-grid and in 2050 the gas-grid should be gone and everything should be done electric. So the gas network will be written off in 30 years.

Though it's weird our neighbours (germany f.e.) are transition to gas - which is better than what they currently have, but still weird.

We have too much people for the area of land we have/ are too efficient in using things/ are too rich compared to other countries thus our emissions are relative high, even though we are also relative clean. And the focus is too much on nations and not on continents/globally.

When we close steel factories in IJmuiden and the coal-power-plants, our emissions drop significant, but global emissions will probably be rise, because we need to buy our energy elsewhere and there still is demand for steel.

So I want us to give the good example and take action, but it shouldn't make the global situation worse. So which is the lesser evil to choose from? Do nothing or do something, but increase global emissions...

Arctic sea ice / Re: The 2019/2020 freezing season

Finally a century increase, first of this melting season;

In the last 30 years (1990-2019) only in 1996 the first century increase was later, november 26th, but 1996 also had the highest minimum in the last 3 decades.

Another maybe interesting fact, since minimum the gain was 1.271.299; When we check other years, the gain from minimum was till october 17th was on average 2.1M. (90's: 2.18, 00's 2.09, 10's 2.07). That it is the lowest gain from minimum till october 17th in the last 30 years; 2018 2nd in that ranking, 2007 3rd;

with only 1 day after minimum with a not-so-large increase, I wouldn't call minimum yet personally. Yeah, it's possible, but we are in a fluctuating period. A drop today isn't unlikely

Yeah, the difference between 2012 en 2019 is small and a huge cap with all other years; Based on this I expect that area/extent numbers will continue to show at least average drops. Low Volume should become visible in extent/area I'd say

Arctic sea ice / Re: Latest PIOMAS update (August)

I think PIOMAS overestimates the ice at the ESS, it looks really fractured at worldview on the 31st, and it doesn’t improve last days...

Clear worldview images :) One advantage of clear skies. Unfortunately it's probably bad for the ice...

I think everything to the left of the red arrow is, especially if melting conditions aren't unfavorable, at risk to completely meltout, seeing the state of the ice. Luckily only about 6 weeks till melting season ends.

And the part between the orange lines doesn't look that good either, if that melts out the CAB falls apart...

Consequences / Re: Heatwaves
« on: July 31, 2018, 04:02:55 PM »
Yeah, same here; I live near the largest 'forest' in the Netherlands, but it's all sand where it's growing on, so it's extremely dry. Lot's of small fires in the region along the roads/train tracks. All the heath is dried out and a ticking time bomb. Too often cigarettes thrown away by people...

does the atlantic ocean communicate freely with the other oceans?

So massive thickening in the CAB, so I presume melt season somehow ended already?

It measures thickness in a reliable way if there are no melt ponds and/or open water is absent. So underestimation in the summer. Although it gives an indication if melt is happening, because when thickness decreases fast during summer, there are either a lot of melt ponds, a lot of open water between floes or thickness is really decreasing.

So based on the satellite images you can safely state the ice is in a bad condition

Yeah, Kara is spectactulair/terrifying to see on Worldview when you animate last weeks

How reliable is this animation? Because if this is true almost all ice outside 80 degree is below 1m, thus doomed. Or there is a lot of open water, which lowers the ice thickness, which also isn't very good news I'd say.

Too bad we have a lot of clouds on Worldview. Any suggestions for layers/overlays to increase the visibility? I've been checking worldview and animated last month for some parts, I can only say for sure that Kara sea is doomed, which isn't a big surprise and I think the beaufort isn't an ice sheet but just a lot of floes, most of them much smaller than I would like.

For example 2 pictures of beaufort/cab 4 days ago, low on clouds, doesn't look that good. I think it's among the worst years for this region around this date (2015 and 2016 beging the other 2 worst years) but I think the 'bad' region extends closer to the pole (but those clouds...)

Arctic sea ice / Re: When will the Arctic Go Ice Free?
« on: July 12, 2018, 10:25:42 AM »
I go for 2018-2020;

I can't believe this year will be the year, although the ice is falling apart in small parts quickly, the melt season will be too short/ freezing will start soon enough, but based on the graphs/ satelite numbers etc. I think the state of the ice is changing so fast the models overestimate ice-quality and it's much worse than it appears to be.

And even then I think/fear we will reach record low numbers end of august/ in september.

I also really really like them, the more charts, the better :)

If they don't go this year, why do they need ice-breakers? ;)

Or we are quickly heading to an enormous cliff. Partial melted out areas don't show up that easily on the charts, especially is there is lots of dispersion going on.

Weaker ice is easier dispersed I guess, since it will probably be more mobile. And it doens't matter if the ocean has a lot if ice that is 200cm thick or 20cm thick, it still is 100% ice-covered. Till it goes *poof*.

Which I fear is something we will see happening
