Plundering Africa

Aquaculture provides seafood in a warming world. But this global industry is taking a staple called sardinella from the mouths of people who need it the most.

From the shrimp ponds of China's river deltas to the salmon cages of Norway's fjords, the industry thrives by feeding fish to other fish. Its needs are so voracious, roughly 20 percent of the world's wild-caught fish don't even go near anyone's plate but are instead ground up to make fishmeal.

Why don't CO2 and temperature correlate perfectly?



This episode discusses the factors that explain why carbon dioxide and temeperature don't correlate perfectly. 0:00-1:27 -Global Temperature and CO2 graphical representation -Decade to Decade time scale variability 1:28-4:06 -Graphs of isolated scenarios for temperature change (Anthropogenic greenhouse gases, Anthropogenic Aerosols, Volcanic Aerosols, and Solar radiation) -Graphs of all influences combined 4:07-7:34 -Internal Variability (changes in ocean heat absorption) -Fictional Example of isolated Internal Variability and example with combined Greenhouse Gases
