The Greening of the World

Post by Jim Steele » Wed Feb 22, 2017 1:51 am

The debate???

I posted the graph below of global greening as evidence of CO2 benefits.

Bobbo protested stating
plants may grown more green....more leaves and bulk and what not BUT THE FOOD CROPS HUMANS RELY ON ARE THEREBY NEGATIVELY AFFECTED.... because the growth goes to the green and diminishes the productivity of the food grain

I argue Bobbo could not be more wrong. More green means more energy is stored and thus enables more productivity of fruits and seeds. Although it is true plants will delay seed set in order to store more energy, that extra energy still results in more food at a later date. Again greening does not mean food grains have diminished.

Its easy to google, lets time it: starting with (co2 plant growth food productivity) and see what we get?

6:51====>First relevant hit: Climate myths: Higher CO2 levels will boost plant growth and food production

then: "Scholarly articles for co2 plant growth food productivity
Potential impact of climate change on world food … - ‎Rosenzweig - Cited by 1869
Food for thought: lower-than-expected crop yield … - ‎Long - Cited by 1095
Food security: the challenge of feeding 9 billion people - ‎Godfray - Cited by 3400

Its: "multi-factorial.".................................. so.................. pick your cherries.

6:54==not interested in reading it all again...but last read was years ago.

What's that bit blue bit in Western Australia? It doesn't seem to correlate with other maps.

It would be informative to research that point...... but JS never provides links. He likes keeping the details a secret.

It's the red desert. It's red because of the iron oxide in the soil, which is why many of our iron mines are in this region. The salt tables are just below the surface and I'm not sure how rising sea levels will "green" this area by salting the land.

It's also totally flat for areas the size of the entire UK, and floods everywhere when it rains. The soil is terrible.
