"[Each Sequoiadendron tree] can potentially pull an average of 85 kilograms of carbon out of the atmosphere per year". I will try to remind this phrase, specially the per year part.

Or about one air passenger trip to Europe. ("just plant trees" is not a viable solution to climate change unless you can plant a very large number of trees which live to maturity)

What exactly are you saying is equal to "about one air passenger trip to Europe"?

OP says 85 kg/year of Carbon per really big tree.

The first calculator I tried said a one way trip from NYC to London on a 787 is over 1000 kg of CO2: https://co2.myclimate.org/en/portfolios?calculation_id=67960...

Now, C is about 25% of the weight of CO2, so this would be 250 kg of Carbon. Is the calculator overestimating? Is my math wrong? Am I interpreting you wrong? Or are you low by a factor of 3?

Is there a handy guide to tell them apart? I live in south Texas and we have a redwood tree in our backyard, which was planted by our previous owner when he moved here from California. I have no idea which type of redwood it is. It is not Texas redwood, though.

> these seedlings will die as the duff dries in the summer Again the myth of Prometheus, "they need fire, burn, burn, burn"... Yawn. may die --On California-- UK is a little more humid. Sequoiadendron grows happy in most temperate areas, including most of Spain. Segovia has some of the tallest trees out of USA, and is a hot place on summer. We have also a few small Sequioadendron forests on the North of Spain since 1…

I've always found the idea that a tree that lives for 2000 years "needs" fire for reproduction on human timescales dubious. The places these trees grow naturally are not naturally fire prone. Go look at any lightning strike map.

forrest fires are not actually that uncommon, and contrary to what some agenda pushers say, they are not caused by climate change. a great many are by arsonists (of which the media then ignores), and the rest happens naturally. Due to poor forrest management (of preventing smaller fires), it then turns into megafires

It might be a dawn redwood (metasequoia), we have them in NJ and they do really well here. They are originally from some random valley in China and were thought to be extinct to westerners (only showing in fossil record) until 1940's or so.

Also in the LA area is a great grove of coastal redwoods: https://www.outdoorproject.com/united-states/california/redw...

That's interesting thanks for sharing, I have been there many times to mountain bike but never saw the grove, next time I will make a trip to that side of the park.

Now re-forest the whole Scottish Highlands please...

The haggis requires very specific ecological conditions for its eggs to mature.

I thought haggis were mammals. Don't they give birth to live young?

Thanks. I googled it but doesn't look the same.
