Thread: Katoomba Monthly Temp average set to be SMASHED!!! AGAIN!!!

Here is a rather interesting report/read about the uptake of CO2 in Biomass.

Biomass fuels can significantly mitigate global warming | EurekAlert! Science News

I wonder if, with the plague shutting everything down everywhere, whether this has had a recordable, measurable impact to the positive to world already?

Not just in one region, but are the atmospheric people saying "well, gee whizz, look at THAT"....

Who's first then eh?

Aircraft contrails & associated albedo impacts will be affected. Whether or not this will have a measurable impact on weather is debatable. The changes from the grounding of planes after the 911 attacks were measurable, but impacts are still being analysed and initial claims of effects on weather have been refuted in some studies.

Short term changes in travel & consumer activities are not going to have a climatic impact. However if this virus were to result in long term behavioral change (such as far fewer commuters, significantly less international travel etc) then I suspect it could have a positive benefit for climate.

Seeing as how you have been the most vocal about it, lead on McDuff......

Yes. It took 150 or so years for the weather to be (noticeably) affected, so a few weeks/months off won't have any real affect at all. Certainly, just like in the weeks leading up to the Beijing Olympics, a few weeks off has an immediate affect on pollution, which can be seen. (it's like the old having a plaster cast verses poor mental health...nothing to see so it isn't real.)

Nah, some noble soul has to be last

Its was just a question

No need for executions. The WuFlu will fix that given time.

Like the grounds around Chernobyl and Fukushima, I'd be keen to see if we (as in, The Entire World) locked away in our caves for 4 or 8 weeks, will lead to a good chunk of global change in some highly measurable, non-esoteric measure.

Its one thing to look at India, Iran and China and bzzzztttt, 2 billion gone... but since we arent driving and belching into the air..... well, how long until Nature aserts itself.

Will we see a blip?

If so, those conservatives are going to have a collective coniptive hernia and stroke!

almost certainly no.

atmospheric CO2 has a half-life of 100 years. (I believe the scale is logarithmic so 100 years is probably more an approximation than an exact figure.) What that means is that in 500 year's time, call it the year 2500, 3% of the CO2 added in just 2019 will still be floating around in the atmosphere. Factor in the 50 years since just 1970 and the amount of carbon dioxide to be broken by solar radiation down is huge.

BTW
atmospheric CH4 (methane) has a half life of 12 years (same caveat as for CO2) so for a person born today, by the end if their life-time most of the methane will be gone. The only little problem being with current temperatures the permafrost is melting and the continental shelf methane clathrate deposits are potentially unstable. Methane has a global warming potential (compared to CO2) of 86 over 20 years and 34 over 100 years.


General air pollution (nitrogenous oxides, sulfur oxides, etc) on the other hand will most likely show a very obvious temporary decline.

Well, here is some bad news for the emerging tech companies....

WTI (the good stuff) is now down to $23.35 a barrel.

The poor old Aussie Dollerydoo is getting it in the neck too, but that price will translate into raw input costs of 1/4 of what was previously. Are we looking at 80c a litre fuel?

Even RBOB (essentially fuel) is down from 3.000 to 0.6698.... a 77% drop from the top.....


This is bad, bad, bad.

Not bad from a price perspective, but bad from an environment one.

The helicopter money will start very soon. What a schite-show this is......


Im tired. Its 2:30am and the markets are going mental. Bed time!

Interesting reports from CAMS (the Euro space agency satellite monitoring service), where they have been monitoring NO2 - noticeable declines over Italy & China. Also PM2.5 declines of 20 - 30% over China

As Ian says, this will only be a temporary blip.

...unless COVID 19 ensures that we are just a temporary blip.

According to Bronwyn Bishop it’s all going to plan
