“Observations do not show rising temperatures throughout the tropical troposphere unless you accept one single study and approach and discount a wealth of others. This is just downright dangerous. We need to communicate the uncertainty and be honest. Phil, hopefully we can find time to discuss these further if necessary,” writes Peter Thorne of the UK Met Office.
“I also think the science is being manipulated to put a political spin on it which for all our sakes might not be too clever in the long run,” Thorne adds.
Nice try Moonbat. That was from 2005 in emails when the FIRST IPCC assesment was being drafted, and underscoring the need for confidence intervals, which at that time were much more difficult to calculate.
In 2014 Thorne was a Lead Author of the FIFTH IPCC Assessment:

And what do the authors now agree on 10 years later with more data and better models?
Conclusions of AR5 are summarized below:
Working Group I
============
"Warming of the climate system is unequivocal, and since the 1950s, many of the observed changes are unprecedented over decades to millennia".
"Atmospheric concentrations of carbon dioxide, methane, and nitrous oxide have increased to levels unprecedented in at least the last 800,000 years".
“Human influence on the climate system is clear. It is extremely likely (95-100% probability) that human influence was the dominant cause of global warming between 1951-2010.”
Working Group II
=============
"Increasing magnitudes of [global] warming increase the likelihood of severe, pervasive, and irreversible impacts"
"A first step towards adaptation to future climate change is reducing vulnerability and exposure to present climate variability"
"The overall risks of climate change impacts can be reduced by limiting the rate and magnitude of climate change"
Working Group III
=============
“Without new policies to mitigate climate change, projections suggest an increase in global mean temperature in 2100 of 3.7 to 4.8 °C, relative to pre-industrial levels (median values; the range is 2.5 to 7.8 °C including climate uncertainty).”
“The current trajectory of global greenhouse gas emissions is not consistent with limiting global warming to below 1.5 or 2 °C, relative to pre-industrial levels. Pledges made as part of the Cancún Agreements are broadly consistent with cost-effective scenarios that give a "likely" chance (66-100% probability) of limiting global warming (in 2100) to below 3 °C, relative to pre-industrial levels.”
