On climate change

Two interesting items in Scientific American of relevance to us in Guyana, both on climate change issues.
Firstly an article on intense rainfall which we seem to be getting more of lately:
"The heaviest rain bursts within a storm happen when it’s warmest, according to new research that suggests rising temperatures could exacerbate flooding as intense downpours are concentrated into smaller windows."
Secondly an item on plant growth. It had been expected that climate change would have boosted plant growth and agriculture worldwide however things may not be as simple as that:
"Drought and limited sunlight will undermine any gain from a warmer atmosphere. By 2100, Mora says, “there could be an 11 percent reduction in the plant growing season worldwide.”"
