Here is some more proof of the harm done by climate change. Of course Irma destroying Florida citrus crops will only make things worse. Eleven percent of the world population doesn't have enough food, this at a time when corporations and the wealthy are raking in record profits. This disproves both the myth that climate change doesn't exist and the myth that capitalism provides for everyone's needs.

The great nutrient collapse
In the outside world, the problem isn’t that plants are suddenly getting more light: It’s that for years, they’ve been getting more carbon dioxide.
Plants rely on both light and carbon dioxide to grow.
If shining more light results in faster-growing, less nutritious algae—junk-food algae whose ratio of sugar to nutrients was out of whack—then it seemed logical to assume that ramping up carbon dioxide might do the same. And it could also be playing out in plants all over the planet. What might that mean for the plants that people eat?
But as the zooplankton experiment showed, greater volume and better quality might not go hand-in-hand.
In fact, they might be inversely linked.
As best scientists can tell, this is what happens: Rising CO2 revs up photosynthesis, the process that helps plants transform sunlight to food. This makes plants grow, but it also leads them to pack in more carbohydrates like glucose at the expense of other nutrients that we depend on, like protein, iron and zinc.

It there is something called "The Alta Mira cycle. WSU archeologists found it on a dig in Spain. They back tracked it to the Marmesca e on the Palouse . Dating "Marmes Man" helped. Our climate flipped every 3500 years, and it's doing this now. Within a couple centuries, it will be warmer and wetter, or cooler and drier. This latter change means mass starvation around the world. Warmer only moves agricultures North a hundred miles or so! reply to: SR1TX
