Guest opinion by Dr. Tim Ball | Canadian Prime Minister Stephen Harper proudly announced discovery of one of Captain John Franklin’s ships, either the Erebus or Terror. Identification, of which ship will be relatively easy, based on the known dimensions of the vessels (Figure 1). Figure 1: Erebus and Terror; sketch in the London Illustrated…

Inconvenient: New paper finds the last interglacial was warmer than today – not simulated by climate models

[Reposted from the Hockey Schtick] A new paper published in Climate of the Past compares temperature reconstructions of the last interglacial period [131,000-114,000 years ago] to climate model simulations and finds climate models significantly underestimated global temperatures of the last interglacial by ~0.67C on an annual basis and by ~1.1C during the warmest month. This…

Claim: study published in Nature shows that small variations in the climate system can result in dramatic temperature changes

Has the puzzle of rapid climate change in the last ice age been solved? Bremerhaven, Germany, August 19th, 2014.  Over the past one hundred thousand years cold temperatures largely prevailed over the planet in what is known as the last ice age. However, the cold period was repeatedly interrupted by much warmer climate conditions. Scientists…
