Letter to MIT President Reif in effort to dispel dangerous warming delusions

without comments

In a letter dated June 2 sent to the MIT Community entitled, “Letter regarding US withdrawal from Paris climate agreement,” MIT President, Professor L. Rafael Reif criticized the decision taken by President Donald Trump to exit the Paris Agreement. In the following rebuttal of Professor Reif’s letter, we seek to clarify the state of scientific understanding of climate. We do so in order to dispel the popular delusions that we are faced with a problem of dangerous manmade global warming, and that the Paris Agreement would be beneficial.

1. “Yesterday, the White House took the position that the Paris climate agreement – a landmark effort to combat global warming by reducing greenhouse gas emissions – was a bad deal for America.” [Emphasis added to correspond to our comment.] Reif (2017).

To the best of our knowledge, there is no scientific basis unambiguously establishing that CO2 is the main driver of the modest temperature increase observed since the end of the Little Ice Age… [More]

May 2017: Global temperature ticks up for 2 months running

without comments

A good month for Mr Gore with UAH’s global average temperature figure almost on the Gore/IPCC red warming line after two months in a row of increasing temperatures. This is an uncommon event: during the 113 months of the bet, so far, temperatures have increased for two months running only 20% of the time.

Runs of temperature increases or decreases are the exception. Three months of increasing temperatures has only occurred for 6% of the bet months, so an increase again in June would be even more unusual. By contrast, three months running of falling temperatures has occurred for 9% of the 113 bet month.

Despite the warmer month, Mr Gore’s cumulative absolute forecast error remains nearly 22% greater than the error from Professor Armstrong’s Green-Armstrong-Soon no change forecast.
