A new study led by a researcher at Cornell University confirms what we’ve known for some time now: that the massive wastewater injection associated with “fracking” (hydraulic fracturing) has greatly increased earthquake activity. In this case, the area of study is Oklahoma.

What We’re Up Against

There’s a post at WUWT which is really a cross-post of this by Harold Ambler. It claims that the NOAA temperature map for this February is “less than accurate.”

Arctic Sea Ice Decline

Reader “fiq” recently asked some questions about sea ice, in particular, whether or not Arctic sea ice decline can rightly be called “staggering.” That’s fine, they were good questions. But when he didn’t find the answers to his liking, he spent “a few minutes looking at the data” and decided to accuse climate modelers of institutionalized incompetence, liken me to a monkey who “sees a short stack of bananas on the next tree and reports to the other monkeys that all the bananas are going extinct,” and refer to my regular readers as “fawning uncritical thinkers,” the kind who “believes you without demanding evidence“.

Regular readers might well take offense at that. Regular readers also know my regular approach.

Let’s look at the data.

Global Temperature: the Post-1998 Surprise

Given how rapidly global temperature was rising prior to 1998, what’s the most surprising thing about global temperature since 1998?

Most who call themselves “skeptics” of global warming would probably say “No global warming since 1998!” Under the name “hiatus” or “pause,” it features prominently in public discussion and even in senate testimony (e.g. from Judith Curry). In truth, such a “pause” or “hiatus” is not that surprising, neither from a statistical point of view nor based on climate model output. But there is one thing about post-1998 temperatures, compared to the pre-1998 temperatures, that is quite a surprise.

Judith Curry responds … sort of

Let’s be crystal-clear what the issue is. The issue is temperature in the Arctic, not some sector of the Arctic, not some season in the Arctic, and the real issue (the point of dispute) is: temperatures since 2000 compared to temperatures in the 1930s (and/or 1940s if you wish). Don’t let anybody — not Judith Curry, not me — get away with avoiding the issue.

The Rise and Fall of Judith Curry

We’ve been looking closely at the written testimony from Judith Curry before a recent meeting of the Environment and Public Works committee of the U.S. Senate. What we’ve seen so far argues against relying on Curry to give accurate and relevant information.

True Lies

I’ve read the written testimony from Judith Curry before a recent meeting of the Environment and Public Works committee of the U.S. Senate. There’s plenty of stuff that gobsmacked me, but let me tell you what astounded me most on my very first reading.
