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.

Mid-Year Update on Global Temperatures

NOAA’s National Climatic Data Center (NCDC) have announced that the Earth has just experienced its warmest June on record, 0.68°C warmer than the 20th-century June average of 15.5°C. Most of the globe was warmer than usual, with the highest temperature anomalies seen in eastern and western Asia, eastern North America, western South America, and most …

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 …

2010 Shaping Up To Be Warmest Year

The Earth has just experienced its warmest March, April, and May on record, according to the US National Climatic Data Center (NCDC), and 2010 is well on track to becoming the warmest year on record. March 2010 was not only the warmest March globally, but also the third warmest month of all time. I don’t …

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 …

Introducing “2010 Global Temperature Watch”

There’s a good chance that 2010 will be the warmest year in the global surface temperature record. So I figured it’s worth keeping an eye on global temperatures this year. I’ll be posting regular updates on a new page called “2010 Global Temperature Watch”. Here’s a sample: 16 April 2010 According to NCDC, the global …

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 …
