Countries Want to Plant Trees to Offset Their Carbon Emissions, but There Isn’t Enough Land on Earth to Grow Them <https://news.google.com/articles/CBMinAFodHRwczovL2luc2lkZWNsaW1hdGVuZXdzLm9yZy9uZXdzLzAxMTEyMDIyL2NvdW50cmllcy13YW50LXRvLXBsYW50LXRyZWVzLXRvLW9mZnNldC10aGVpci1jYXJib24tZW1pc3Npb25zLWJ1dC10aGVyZS1pc250LWVub3VnaC1sYW5kLW9uLWVhcnRoLXRvLWdyb3ctdGhlbS_SAQA?hl=en-US&gl=US&ceid=US%3Aen>

Darwin came to about the same conclusions

“And God said, Let us make man in our image, after our likeness.” *

“… man hath no pre-eminence above the beast: for all is vanity.”**

*Genesis 1:26 <https://biblehub.com/genesis/1-26.htm>

Earlier this year, an IPCC report found that the majority of all adaptation actions (changes humans will need to make in response to climate change) are water-related. <https://www.eurekalert.org/news-releases/970145>

The Economist Nov 5th 2022

Briefing  <https://www.economist.com/briefing>| An inconvenient truth

The world is going to miss the totemic 1.5°C climate target
It needs to face up to the fact
https://www.economist.com/interactive/briefing/2022/11/05/the-world-is-going-to-miss-the-totemic-1-5c-climate-target <https://www.economist.com/interactive/briefing/2022/11/05/the-world-is-going-to-miss-the-totemic-1-5c-climate-target>

excerpt

Most in the field know this to be true; those who do not, should. Very few say it in public, or on the record. An activist movement based on galvanising enthusiasm is hard put to admit defeat on its chosen goal. Doing so can also feel, to those who care, like giving up on the poorest, who will suffer more than any others after the threshold is breached.

But the truth needs to be faced, and its implications explored. What does the certainty of a post-1.5°C world mean for the planet? Can a world which warms significantly more find its way back? And what will missing a totemic target mean for the credibility and sustainability of continued efforts to limit climate change?

The Hunger Games for insects

"Our study suggests that increased insect herbivory is likely to be a net long-term effect of anthropogenic pCO2 increase and warming temperatures."

"Food webs incorporating plants and phytophagous insects account for up to 75% of modern global biodiversity (2), so their response to this anthropogenic change will have a profound effect on the biosphere. Experiments show that plants grown in elevated CO2 tend to accumulate more carbon and have a higher carbon:nitrogen ratio; they are, therefore, nutritionally poorer (3–5), leading to an average compensatory increase in insect consumption rates (6) as nitrogen becomes limiting."

“Plants that are tall with isohydric stomatal regulation, low hydraulic conductance, and high leaf area are most likely to die from future drought stress. Thus, tall trees of old-growth forests are at the 
greatest risk of loss, which has ominous implications for terrestrial carbon storage.”
