Iccc-14 Preview, Ep. 4: Roy Spencer On “what Recent Ocean Warming Suggests About Future Warming”

The warming predicted by the latest climate models in response to a doubling of atmospheric CO2 averages close to 4C. Using an updated model – and even assuming all warming has been due to human activity – Spencer and a colleague suggest that...

Global Peatland Dry-out Could Release 860 Million Tons Of Carbon Dioxide Per Year

Peatlands, such as fens, bogs, marshes and swamps, cover just 3% of the Earth's total land surface, yet store over one-third of the planet's soil carbon. That's more than the carbon stored in all other vegetation combined, including the world's...

Sea Level Rise Fastest In 2000 Years (or Not!)

As the actual data shows, the rate of sea level rise in New Jersey has been pretty constant since 1910, which suggests that carbon dioxide emissions have little overall effect. What we are seeing is the result of natural global warming since the...
