watching F1, they laid 24,000 tonnes of asphalt on a Miami carpark and will be ripping all out after the event, track temp is 53C in spring.

just to fly a circus of 20 billionaires and millionaires across the world for one week to burn 13 sets of rubber each for the world to watch sports.

i'm loving the show but am I contributing to climate change? it seems to be the only sport i watch this year so keeping the CO2 to the minimum ...

Maybe they could donate it to us as aid when they’re done with it so we can have better roads?

We've contributed a fair bit on both sides of the ledger in the last 12 months.

On the positive side:

Installed 5kw of solar power which covered ~40% of our electrical usage.
Moved to a PHEV from an older Prius and Toyota wish, should result in a 90% reduction in petrol use per annum (mostly drive within the battery range).
Started planting out the gully with native trees and bushes.

On the negative:

Installed a pool which will probably result in a very slight net increase in electrical usage vs pre-solar, but will increase our solar utilization to ~95%.
Have been cutting down and burning all the privet, blackberry and willow that currently occupies the gully.

On the neutral:

Significantly shifted our power usage away from peak times to off-peak or solar periods, so hopefully less coal power being used...

Something Ive mentioned occasionally here, global cooling. Now its playing out.

We have increased global warming massively. Lets says its about 1 degree. But it may be 2 degrees, even though measures dont show that. The reason is the global warming could already be 2 degrees, but 1 degree is offset by the cooling effect of particles that each hold moisture. Turn the heat up 2 degrees, but have an umbrella that now makes it feel like 1 degree. But its really 2

Mentions Elon Musk, because of course.

Instead of worrying about population decline, we should be celebrating it.

South Korea has been pummelled by rain. Here in ChCh we were too, twice recently. Last year I struggled to manage my tomato plants in two unseasonal high Summer rain events. All over the place, and 100% certain these global and NZ events are standard now. More heat more atmospheric water.

Did Eric Clapton really think she looked wonderful...or was it after the 15th outfit she tried on and he just wanted to get to the party and get a drink?

Pity as that's easily solved, but too much hassle for some

Landfill should be inanimate waste, animate waste gets composted as nature does

This is an 2 year old article, but I think it's still applicable. Basically it's a positive feedback loop.

There are similar articles dating back to 2005.

The Guardian: Arctic methane deposits 'starting to release', scientists say

Scientists say they have found evidence that frozen methane deposits in the Arctic Ocean have started to be released over a large area of the continental slope off the East Siberian coast, the Guardian can reveal.

High levels of the potent greenhouse gas have been detected down to a depth of 350 metres in the Laptev Sea near Russia, prompting concern among researchers that the discovery could have “serious climate consequences”.

The slope sediments in the Arctic contain a huge quantity of frozen methane and other gases – known as hydrates. Methane has a warming effect 80 times stronger than carbon dioxide over 20 years. The United States Geological Survey has previously listed Arctic hydrate destabilisation as one of four most serious scenarios for abrupt climate change.

The international team onboard the Russian research ship R/V Akademik Keldysh said most of the bubbles were currently dissolving in the water but methane levels at the surface were four to eight times what would normally be expected and this was venting into the atmosphere.

Yep

It states "This is similar to the craters and sinkholes reported from inland Siberian tundra earlier this autumn."

I watched a doco, maybe 5+ years go, in Siberia the scientists said that the tundra is warming, it was only -0.5 or so. They made a shallow hole, lit a match and the methane lit. It will be worse now. Ive annecdotally noticed an uptick in climate change disasters, especially the last 12 months. Excessive rainfall being quite common now. I dont know how you can stop the methane feedback loop in the Arctic. Its gone too far and its too big.

tdgeek:

Yes, it's understood to mitigate the greenhouse effect by about 2°C , certainly a huge concern but only if the world stops emitting particulates, even more unlikely than not burning fossil fuels.

Lucky for us in NZ most of the more-severe action will take place in the Northern hemisphere in the immediate future, thanks to the rapid warming of the Arctic in combination with Greenland's land ice mass being offset from the north pole.

Antarctica being mostly land ice and roughly centered on the south pole will keep our weather somewhat stable. Mostly we'll be stuck with 'just' much heavier rainfall.

Hopefully we'll wake up and start planning to build new highly-sustainable towns away from low-lying areas and sea level rise threats. We shouldn't be letting ourselves descend into chaos as will certainly happen in the US.
