For those skeptics that has the earth is not warming, tell it to those who will starve as a result of global warming. All you need to do is think about the world as home, and what we can do to help clean it up.
BBC News - Climate to wreak havoc on food supply, predicts report
Some areas in the tropics face famine because of failing food production, an international research group says.
The Climate Change, Agriculture and Food Security (CCAFS) predicts large parts of South Asia and sub-Saharan Africa will be worst affected.
Its report points out that hundreds of millions of people in these regions are already experiencing a food crisis.
"We are starting to see much more clearly where the effects of climate change on agriculture could intensify hunger and poverty," said Patti Kristjanson, an agricultural economist with the CCAFS initiative that produced the report.
A leading climatologist told BBC News that agriculturalists had been slow to use global climate models to pinpoint regions most affected by rising temperatures.
This report is the first foray into the field by the CCAFS initiative. To assess how climate change will affect the world's ability to feed itself, CCAFS set about finding hotspots of climate change and food insecurity.

"We are starting to see much more clearly where the effects of climate change on agriculture could intensify hunger and poverty,"
There is a chance climate change could have an impact on hunger and poverty that already exist. As will growing populations, poor land management and market manipulation of food prices.

We really do need to find better agricultural methods.

If the temperature is too hot and there isn't enough water what exactly would you suggest? Our current agricultural methods already create more food per acre than at any time in the past by relying on the influx of petrochemical.Originally Posted by Commodore

Move everything indoors, employing aquaponics, LED/Optical lighting, and CO2 tanks to enable year round production of everything from salad staples, to tropical fruit, to cereals, to fibrous plants, to weeds for your rabbits to eat, to algae for livestock feed and vegetable oil fuel.
Oh, and you can also eat the fish.

Seems like you don't have it right... again.
More GW = more CO2 = better plant growthA team of scientists at Rothamsted, the UK’s largest agricultural research centre, suggests that extra carbon dioxide in the air from global warming, along with better fertilisers and chemicals to protect arable crops, could hugely increase yields and reduce water consumption. “Plant breeders will probably be able to increase yields considerably in the CO2 enriched environments of the future … There is a large gap between achievable yields and those delivered … but if this is closed then there is good prospect that crop production will increase by about 50% or more by 2050 without extra land”, says the paper by Dr Keith Jaggard et al
How about that!?!

Sub saharan Africa has been a ag mess for my entire life. Was there ever a time it was not ?
Population demands have depleated the ag supply and been far more of a cause of shortage than anything else will ever be. Oddly enough if we can get the more frigid parts of the world into longer growing seasons it would be a boon so let shope for continued improvement.
Oh and by the way, stop making fuel out of food. There are people dying for that corn.

Better plant growth does not necessarily equate to better CROP growth, it's more complex than that. Higher temperatures means that growing zones are changing and traditional bread-basket areas may lose their optimal temperature cycle that makes certain crops grow so well there. Having excellent weather for a particular kind of crop does you very little good if it's centered in a wasteland.
It's also a problem if more CO2 is put into the atmosphere than plants can remove, for obvious reasons.

Over 3000 year ago. Climate change has been the bane of poor populations for centuries now it would seem.

Do you think that in a world, which is already depleting its fresh water supply at a prodigious rate, we can use aquaponics to provide food for 8.9 billion people. In areas like China, Africa and India where do you think they are going to get the fresh water.

How much water do you think it would take to provide hydroponic and aquaponic food for the worlds increasing population?
There is an invisible daemon at work which most people miss. Everyone sees one problem at a time and doesn't want to see the unprecedented collection of issues coming towards us.
Increasing population (est. 8.9 billion people by 2050 ).
Commodity peaks (nitrogen, phosphorous, water, natural gas, oil, uranium, etc.)
Soil degradation (nutrient loss, erosion, pollution).
Climate change (yes, I know, your probably don't believe in it).
I know that people don't want to see the daemon but the daemon is there - a continued world population in excess of 6 billion people is simply unsustainable in a closed system. People are going to die and it is just a matter of how many, how fast and how painful.
Vice President
Yes, climate does change and has been doing so forever even without SUVs.

So do we start killing them now or do we wait and kill them off later?

Aquaponics uses considerably less water than conventional agriculture.

Ever notice how many extinct mammals were huge versions of modern mammals? Probably the most plausible reason they were so big is that the planet was warmer back then and able to support more biomass that was in turn able to support more forage for larger critters.
If there is anything to AWG, I'd say it's prophets have it exactly backwards regarding the global food supply.
