Energy savings work!

It had passed me by, but an outfit called the Breakthrough Institute (BTI) has been suggesting that energy savings don’t work, according to a guest post at Climate Progress. They say there is a “rebound effect” which causes 60 to 100% or more of energy savings to be lost. For example, if you save on your power bill you will spend that money on a thing or activity that uses energy. The contention has been amplified in the MSM in the US.

A thorough examination of this theory has found that the rebound effect exists, but it’s 10 to 30%. So 70 to 90% of savings are permanent. This is important because, they say, 25-40% of GHG abatement could be achieved through energy savings. Continue reading Climate clippings 62 →

East Antarctic ice sheet sits on rivers and lakes

The Science Show reported on a new survey of East Antarctica published in nature.

probably something like the Northern Territory area was actually below 500 metres below sea level, and if you look at the deepest bits, something like the size of Tasmania was more than one kilometre deep.

The implication is that at some stage the sheet will melt faster than previously thought.

The lakes are formed through thermal heat from below.
