Climate Change / Global Warming
Dramatic effects possible soon?
- Siberian peat bog tundra is melting
- can global warming lead to catastrophic COOLING in N. Europe?
- Greenland glacial melt shuts down "thermohaline conveyor belt"
- conveyor driven by cooling of salty (evaporation) surface water from south
- cool, salty water denser than cool unsalty water, so it sinks in N. Atlantic
- glacial melt => fresh water dilution of salty water => won't sink
