The cost of displacing fossil fuels: some evidence from Texas

by Peter Hartley

Although technological progress can alter the relative costs of different energy sources, depletion inevitably must raise the costs of fossil fuels leading to their displacement by alternative energy sources. What energy technology will likely be used when fossil fuels are no longer dominant? More importantly, what will be the cost of that alternative “backstop” energy supply?

Nature Unbound VI – Centennial to millennial solar cycles

by Javier

Summary: Holocene climate has been affected in different periods by several centennial to millennial solar cycles. The ~ 1000-year Eddy solar cycle seems to have dominated Holocene climate variability between 11,500-4,000 years BP, and in the last two millennia, where it defines the Roman, Medieval, and Modern warm periods. The ~ 208-year de Vries solar cycle displays strong modulation by the ~ 2400-year Bray solar cycle, both in its cosmogenic isotope signature and in its climatic effects. The Centennial, and Pentadecadal solar cycles are observable in the last 400-year sunspot record, and they are responsible for the present extended solar minimum that started in 2008.
