I am not sure that this high tech oriented environment is right, but I will give it a try.

There is a lot of fuss about global warming, but PhDs generate nonsense on grand scales. And Scientific American demonstrated this in its latest special issue:
Firstly by repeating a false dilemma: Biofuels or Food? As we need arable land to grow organic matter for biofuels!
Then a big Catch-22 article: Water vs. Energy. As we need fresh water to grow organic matter!
Then: Bury carbon dioxide. As there are plenty safe places underground to store compressed gas. Furthermore, nobody appears to be thinking that there is more than two tonnes of oxygen in three tonnes of carbon dioxide, oxygen we need to breathe!

I am worried about what nonsense we offer as “solutions” to our politicians. . .

Cultivating seawater algae on barren land and on massive scales offers rapid capturing of atmospheric carbon dioxide releasing oxygen we need to breath. To enable massive scales we need low tech solutions every farmer can implement. Algae themselves can be used for fertiliser, stockfeed and food production with great potential for biofuel production. With algae, farmers could also grow fish. Algae also desalinate seawater and their fresh water content can be used to increase soil humidity. This brings me to Greening Method (patent pending):

Growing seawater algae in ponds above the ground will shade the soil will reduce humidity loss. Vapour (fresh water) from seawater ponds will further reduce soil humidity loss and algae themselves will increase barren soil humidity, quality and fertility. In short, we can relatively quickly turn barren land into fertile and start growing agroforestry mixes.

Planetary problems need planetary solutions. Growing new forests on lands currently considered barren is such, long term solution. Strategically placed, new forests will induce vertical air circulation bringing rains where we need them the most, a kind of microclimate management.
If properly presented to our politicians with low tech solutions for our farmers and some incentives forests could start to grow soon all over our planet. Aid agencies could also be interested to spread such practices in poor countries.

I guess that CTO could also be interested in quite simple technologies.
