I just heard about a jump in atmospheric methane that is not understood. The oil/gas industry has made some progress to curtail methane emissions so we don't think it is that gang. I wonder about millions of tons of frozen ancient vegetation in Canada and Russia beginning to rot. ?

> The oil/gas industry has made some progress to curtail methane emissions so we don't think it is that gang. I don't know if we can reach that conclusion. It's been discovered, in Canada at least, that O&G is vastly under-reporting its methane production. I imagine other areas of the world might be even worse. https://www.ctvnews.ca/climate-and-environment/30-40-per-cen...

Uzbekistan and Nigeria are pretty bad on methane emissions and the Nordstream attack also released quite a lot.

War is highly destructive environmentally and uses a lot of fuel, so this Ukraine war is not helping.

Blowing up Nord Stream in the spring probably wasn’t a good idea for the environment.

But hey at least we’re sticking it to the fascist Russians. /s

No doubt the big Canadian Barbecue had a significant effect. Not to say there is no trend, just that this particular year is exceptional for at least on reason.

I also wonder if the war in Ukraine had an effect too. To my understanding in a lot of the initial stage, Russia was extracting as much natural gas as stopping the extraction process would render it hard to restart, but with much reduced opportunities to sell it, they were just flaring the excess gas.

Of course, the traditional customers of that gas were burning gas too, sourced from elsewhere via LNG, or in some cases, coal. So in effect in 2022, we ended up double dipping on the european fossil fuel usage as it was burned both in europe and in russia.

>> No one knows the amount of thought I put into this same problem when building train tracks for my son but I had no idea how to solve the problem. My opinion is that it will rise until we reach a tipping point where changes happen that will lead to the next glaciation.

> but an acceleration of a process that has been happening for several million years

That's exactly the main issue, isn't it? A change happening over millenia/millions of years gives enough time and slack for life to adapt, an accelerated change that happens in the course of centuries will just erase many species that can't reconfigure their metabolism through evolution. Of course that life finds a way and new species adapted to a new environment will become more prevalent over time, the issue is exactly that we accelerated it to a pace where most things aren't able to cope. We depend on those things as well to survive.

That's why all the past predictions have been so accurate, right? "But we know more now." We do not. Some intellectual humility by those wanting tyranical control over our lives would be fantastic.

There is not a “decent amount of confidence” and your CNN link provides no proof that there’s any at all outside of a sentence claiming tree rings and coral mean it may be. There is so much disinformation (from both sides) and fear mongering about this subject that anything not a direct and peer reviewed source should not be taken as any kind of proof of anything.

Perhaps we're also measuring temps more than ever with greater data collection.

If we have more data points in cities, this could skew the results. I live in a forested area and going into the city can easily add 3 or 4 degrees Celsius.

Having it operational and delivering gas for decades to come would have been worse for the environment. Germany is still a bit tumbling but definitely will move from gas and oil to other means of heating.
