Real Climate Science

I normally focus on NASA and NOAA altering the temperature record of the past 150 years, but once in a while it is a good idea to remember that the same alteration is being committed with the long term temperature record too. As of 1990, the IPCC showed that the MWP was much warmer than the 20th century.

It is well known that trees grew in Greenland when the Vikings lived there. Greenland is too cold for trees now.

The wineries of England competed with France at that time, but only the southern fringes of England are marginally suitable for wine production now.

But facts don’t matter in modern climate science. It is about keeping politicians like Barack Obama happy, so after the year 2000 they simply erased the MWP and created the hockey stick.

If I was from Ecuador, I would be really pissed off.

“I’m not a scientist either,” Mr. Obama told this young audience, “but we’ve got some good ones at NASA. I do know the overwhelming majority of scientists who work on climate change, including some who once disputed the data, have put the debate to rest.”

What the president is saying is that he is making up statistics about a group of people he doesn’t know much about, and that he understands those people generally keep their mouth shut because they like to keep their funding and job – and avoid McCarthyite attacks like Richard Tol and others have faced.

In my previous post, I showed how NASA has altered pre-1999 US temperatures relative to their previously published data.

The next graph shows their current adjustments since 1998, calculated across all stations with no missing data since 1990. Their post 1998 adjustments are warming the US at 3.6F/century.

In 1999, NASA reported the US was in a 70 year cooling trend.

Whither U.S. Climate?

By James Hansen, Reto Ruedy, Jay Glascoe and Makiko Sato — August 1999

Empirical evidence does not lend much support to the notion that climate is headed precipitately toward more extreme heat and drought.

in the U.S. there has been little temperature change in the past 50 years, the time of rapidly increasing greenhouse gases — in fact, there was a slight cooling throughout much of the country (Figure 2)

That story wasn’t scary and wasn’t going to raise any money for NASA, so they massively altered the data to create a warming trend. The 2014 version adds 1.3C/century warming from 1976 to 1998, which didn’t exist 15 years ago.

Obama Compares Skepticism Towards Climate Change To Believing Moon Made Of Cheese

The only scientist to ever walk on the moon is a prominent climate skeptic. Harrison Schmitt probably does not believe that the moon is made out of cheese.

Forty years ago, climatologists reported 1ºC global cooling, and warned that cooling was going to make erratic weather and starve us to death

The reported cooling has since been erased by government scientists, who are now are paid to push the global warming agenda rather than the global cooling agenda.

Obama, who cited fires in Western states, smaller snow packs in mountainous tourist areas, and flooding streets in cities like Miami to make his case about the fallout from climate change.

Miami was nearly wiped off the map by a hurricane in 1926. Florida is having their longest period on record without a hurricane strike, but they had street flooding and that proves catastrophic climate change.

The president says he doesn’t have any time to talk to global warming skeptics, but considers himself an expert about their beliefs.

EXCERPTS FROM THE CLIMATE REPORT

Published: October 21, 1983

Rapid climate change will take its place among the numerous other changes that will influence the course of society

we are deeply concerned about environmental changes of this magnitude; man-made emissions of greenhouse gases promise to impose a warming of unusual dimensions on a global climate that is already unusually warm. We may get into trouble in ways that we have barely imagined, like release of methane from marine sediments.

the ” CO2 problem” appears intractable. Viewed as a problem of changes in local environmental factors – rainfall, river flow, sea level – the myriad of individual incremental problems

And the same BS from Obama today

“One of the most significant long-term challenges that our country and our planet face (is) the growing threat of a rapidly-changing climate,” the president said at the school in Anaheim. “The overwhelming judgment of science, accumulated and measured and reviewed over decades, has put that to rest. The question (now) is whether we have the will to act before it’s too late.”

Obama told those in attendance that they must respond now to protect children and future generations — a theme he has repeated after announcing in recent weeks new rules for reducing carbon emission for plants that burn fossil fuel.

“We also have to realize, as hundreds of scientists declared last month, that climate change is no longer a distant threat but ‘has moved firmly into the present,’” said Obama in the ongoing effort by him and his supporters to win the debate on global warming and its possible causes. “The overwhelming majority of scientists who work on climate change, including some who once disputed the data, have put the debate to rest.”
