Do the IPCC use alarmist language?

This post was written for Skeptical Science. Graham Wayne has recently written rebuttals to “The IPCC consensus is phony” and “IPCC is alarmist”. But, you might say, that’s only half the story – do the IPCC present their conclusions in an alarmist way? There are many different ways you might look at this, but one …

Skeptical Science posts

I haven’t been posting very often recently, and one reason is that I’ve been busy writing for another climate blog called Skeptical Science which, unlike mine, actually has a readership. Skeptical Science is run by John Cook, and basically the core of the site is an increasingly comprehensive database of rebuttals to the arguments of …

Global Warming Contrarians Part 7: State of the Climate

Claim: There’s no evidence that the global climate is warming. Why worry about a problem that’s invisible? Fact: Just about any aspect of climate you care to look at does show signs of global warming. The US National Oceanic and Atmospheric Administration have recently released their 20th annual State of the Climate report. The report …

Scientific Opinion versus Media Balance

Renegade Conservatory Guy has created an infographic showing the discrepancy between scientific opinion on global warming and public opinion. I think this speaks for itself.

Global Warming Contrarians Part 1.1: Amateur Temperature Records

After a two-month hiatus, I’ve finally completed the next installment in my increasingly non-linear series of posts examining the (mostly bad) arguments against the reality of global warming. Originally I had planned out a sort of arc of subjects to cover, but as I learn more about climate science, I find I want to go …

CO2 hits 390 ppm

The level of carbon dioxide (CO2) in the atmosphere, as measured at Mauna Loa, has just ticked over to 390 ppm. Actually, that’s not quite true — the level is 392.39 ppm as of April. But CO2 levels are slightly higher during the northern spring than the southern spring, because the Northern Hemisphere has more …

Global Warming Contrarians Part 2.1: Cooling Trend or Noise?

In Part 2 of this series of posts examining the (mostly bad) arguments against the reality of global warming, I debunked the oft-heard claim that global warming stopped in 1998. Basically, the people who make that claim are just joining endpoints, rather than looking at the trend from 1998 to now. But there is a …

Global Warming Contrarians Part 6: Global Cooling in the Mid-20th Century

Here, at last, is the much-delayed sixth instalment in my ongoing series of posts on the (mostly bad) arguments that contrarians make against global warming. (A list of earlier parts in the series can be found here.) In this post, I want to clear out of the way one more factoid that contrarians hold up …

Global Warming Contrarians Part 5: Counting Carbon

This is the latest instalment in a continuing series of posts on the (mostly bad) arguments that contrarians make against global warming. A list of earlier parts in the series can be found at the bottom of this post. Claim: Natural CO2 emissions far outweigh our own. Fact: This claim is true but misleading. Before …

Global Warming Contrarians Part 4: Back to Basics

So far in my series of posts on the arguments contrarians make against global warming, I’ve written about the changes being observed in the Earth’s climate. I wrote about whether the global temperature has increased (short answer: yes); whether it has recently stopped increasing (short answer: probably not); and whether ice is declining around the …
