10 years to save the climate?

[Ahmed]

Who has a 200-year-old beech tree and would be willing to photograph a washer?
Occasionally I will have to look at an oak stump (not beech trees), but I doubt very much what is advanced here; Furthermore, assuming that global warming leads to faster growth of trees, as this also results in greater variability in temperatures and rainfall and above all an increase in extreme episodes (to which the averages obviously do not justice), it's a safe bet that this growth only occurs on paper or that it is canceled out by storms (your choice! ).

The increase in temperature is not the main growth factor for trees. and you question the team of Thomas Rötzer, from the Technical University of Munich and scientific research in general, there must be serious reasons for this.
Already quoted:

During the twentieth century, Europe has warmed by about 1 ° C, while its rate CO2 increased over 30% from 295 parts per million (ppm) to 1900 400 near ppm Nowadays. Same thing as to atmospheric nitrogen deposition, which increased from 2,5 9 to kilograms per hectare per year over the same period.

The main growth factor for trees remains rainfall at the right time. I do not deny the increase in CO2 and atmospheric nitrogen, no more than that in temperature, what I doubt is that more CO2 in the air automatically leads to a substantial increase in trees (excluding experiments in controlled environment, therefore).

PS: when rereading my previous message, I see that I expressed myself awkwardly: when I spoke of global warming (CR), I was thinking rather of CO2 ... but the two go together ...

CO2 increases productivity by improving plant growth and vigor.

Plants adapt better to global warming than scientists feared, suggests a new study according to which the rise in the thermometer does not permanently affect their capacity to store carbon dioxide (CO2) ... All plants, and including forests, absorb about 60 billion tonnes of CO2 annually, six times what humans produce by burning fossil fuels.

Thank you, but I have known this carbonate manure method for a very long time ... I had specified:

(excluding experiments in a controlled environment, therefore).

The study "suggests" that "plants adapt better to global warming than scientists feared" ... in consideration of a particular point.
For the moment, in real conditions and on all the factors, to my knowledge there is still no realistic diagram of adaptation of western forests to the current climatic changes (for the other regions of the globe, I do not know nothing).

[chatelot16]

so that the trees grow faster you need both sun water and CO2 ... in recent years I see near my home trees slow their growth or even die due to lack of water .. CO2 or the summer sun does not benefit them due to lack of water

same remark for the CO2 in the greenhouse, I had spoken about it to a horticulturist a long time ago: I spoke to him of the idea of ​​sending in his greenhouse the CO2 of the heating boiler ... answer, this is is useful only if you increase the lighting with electric light otherwise the additional CO2 is useless ... well it was a long time ago, and the horticulturalist had no precise data, maybe that a small increase in CO2 can be used with the normal sun ... but do not expect that the growth is proportional to the level of CO2

[Ahmed]

It does not matter the growth of forests if they are regularly ravaged by storms, fires and droughts of more brutal and more frequent climatic episodes ... The other consequences will in any case be more important than the only question of the forest, considered here under the only, rather trivial, aspect of production ... This accounting perception of CR, with its debit column and its credit column, is in line with the ideology which is its cause.

[chatelot16]

Ahmed you are desperate ... you refuse any idea of ​​improvement because you see only the worst

the case of burning forests is very sad, and it is also a lack of water

when we see what it costs firefighters to put out forest fires in France, if we spent the same amount to maintain or irrigate it would not burn and it would produce more

if we built factories to produce energy with the brush, brushing would not be an expense but an income ... and with a grid of brushed area there would be no more forest fires

and in France it's not the worst, we have firefighters who have almost sufficient means ... in other countries it burns until it goes out on its own

[Ahmed]

I do not refuse the idea of ​​improvement, on the contrary, but I note the facts which flow from the principles which are currently applied and which are only accidentally directed towards the interest of men and even more rarely, since they are the source, towards respect for other creatures and their possibility of life.
What is really hopeless is this generalized movement of self-destruction which makes derisory the "tricks" which claim to free us from it, while they are powerless to go out of its logic.
