The Climate Debate Twenty Years Later (recalling Houston’s 1999 conference)

by Robert Bradley Jr., March 7, 2019 in MasterResource

“Better climate knowledge about natural versus anthropogenic forcing seems to a decade away.” That was the major takeaway from a major 1999 climate conference in Houston, Texas as noted by Martin Cassidy of the Houston Geological Society, who  authored a conference summary, “Global Climate Change: Panel Agrees: ‘In 10 Years We Will Know‘.”

In fact, one of the conference participants, Gerald North, climatologist at Texas A&M, repeated this a decade after this conference. In his words:

In another decade of research we will have squared away a lot of our uncertainties about forced climate change. As this approaches we can be thinking about what to do if the warming does indeed appear to be caused by humans and to what extent things are changing as result. (North to Seldon B. Graham, Jr. January 6, 2010)

Now for Cassidy’s 1,000-word writeup. As you read this, ask yourself: what is really that different today, 20 years later, science-wise?

Planet-Sized Experiments – we’ve already done the 2°C test

by Willis Eschenbach, March 17, 2019 inWUWT

People often say that we’re heading into the unknown with regards to CO2 and the planet. They say we can’t know, for example, what a 2°C warming will do because we can’t do the experiment. This is seen as important because for unknown reasons, people have battened on to “2°C” as being the scary temperature rise that we’re told we have to avoid at all costs.

But actually, as it turns out, we have already done the experiment. Below I show the Berkeley Earth average surface temperature record for Europe. Europe is a good location to analyze, because some of the longest continuous temperature records are from Europe. In addition, there are a lot of stations in Europe that have been taking record for a long time. This gives us lots of good data.

So without further ado, here’s the record of the average European temperature.
