Ken Caldeira

The science is settled huh?

We have been told that the science is settled with global warming, or climate change or climate disruption or whatever other title they use to describe the greatest scam ever foisted on mankind.

Except it isn’t…settled.

One of the world’s most firmly global-warmist scientists says that even if humanity deliberately sets out to burn all the fossil fuels it can find, as fast as it can, there will be no troublesome sea level rise due to melting Antarctic ice this century.

Dr Ken Caldeira’s credentials as a global warmist are impeccable. He is not a true green hardliner – he has signed a plea to his fellow greens to get over their objections to nuclear power, for instance, and he doesn’t totally rule out geoengineering as a possible global-warming solution. But that’s as far as he’ll go: in Dr Caldeira’s view, it is plain and simple unethical to release greenhouse gases into the air. There’s no middle ground on that as far as he’s concerned – he’s not OK with gas power as an alternative to coal, for instance.

But he’s a scientist, and like all proper scientists he’s willing to admit inconvenient truths. In this case, the truth in question is his own prediction that no matter what humans do in the way of carbon emissions, sea levels are not going to rise by more than 8cm this century due to melting Antarctic ice. For context, the seas have been rising faster than that for thousands of years. They rose 17cm just during the 20th century, and the Antarctic cap is far and away the biggest body of ice on the planet.   Read more »

‘Saving Humanity’ can only come via Nuclear power…and warmists have said this

My, my haven’t the tables the turned.

The warmists are now advocating for greater use of nuclear power as the ONLY way to save humanity from global warming. Not just any warmists either…the high priests no less.

Watch the Greens go puce over this.

Four of the best-known scientists espousing the belief that humanity’s carbon emissions are an immediate and deadly threat have issued a statement begging their fellow greens to support nuclear power.

Doctors James Hansen, Ken Caldeira, Kerry Emanuel and Tom Wigley co-signed an open letter over the weekend in which they address “those influencing environmental policy, but opposed to nuclear power”. The four scientists write that “continued opposition to nuclear power threatens humanity’s ability to avoid dangerous climate change … there is no credible path to climate stabilization that does not include a substantial role for nuclear power”.   Read more »

Inmates take over the asylum

Not content with demanding the use of biofuels, with the results that:

  •  Rainforests have been levelled
  •  Subsidence farmers driven from their land
  •  and the world’s poor starve

Green scientists are now proposing to release aerosols all over the globe to “cure” the imaginary disease of global warming.

Solar radiation management is a type of geoengineering that would manipulate the climate in order to reduce the impact of global warming caused by greenhouse gasses. Ideas include increasing the amount of aerosols in the stratosphere, which could scatter incoming solar light away from Earth’s surface, or creating low-altitude marine clouds to reflect these same rays.

Research models have indicated that the climatic effect of this type of geoengineering will vary by region, because the climate systems respond differently to the reflecting substances than they do to the atmospheric carbon dioxide that traps warmth in Earth’s atmosphere. New work from a team including Carnegie’s Ken Caldeira uses a climate model to look at maximizing the effectiveness of solar radiation management techniques. Their work is published October 21st by Nature Climate Change.

Attempting to counteract the warming effect of greenhouse gases with a uniform layer of aerosols in the stratosphere, would cool the tropics much more than it affects polar areas. Greenhouse gases tend to suppress precipitation and an offsetting reduction in amount of sunlight absorbed by Earth would not restore this precipitation. Both greenhouse gases and aerosols affect the distribution of heat and rain on this planet, but they change temperature and precipitation in different ways in different places. Varying the amount of sunlight deflected away from the Earth both regionally and seasonally could combat some of this problem.

The Green movement is the true threat to the Earth and our environment.
