The observed lack of change in global annual average surface temperature over the past 15-years or so is a fact that is being increasingly debated within the scientific literature and in the wider world. It is fair to say there is no consensus over its cause, or about how long it may continue. Although we [...]

It was whispered for months. Then, two months ago, NASA scientist Dean Pesnell came out with an official prediction that the current sunspot cycle would have two peaks instead of only one. He says the 2nd peak will be later this year and possibly last into 2014. This month’s sunspot number is out and shows a secondary [...]

With all the talk about global sea levels, it is easy to lose track of what is happening all around us, in the places where we actually live. Here in the UK, back in 2009, the government organised a series of Regional Climate Adaptation Studies, that warned us to expect sea level rises of 0.35 metres [...]

So why do they persist in making these predictions? Perhaps they just can’t help themselves, perhaps they are all pathological liars. Or perhaps they just are not very good scientists. The threat of widespread and persistent drought, ruining crops and threatening water supplies, is constantly cited as an outcome of global warming. Media talking heads, [...]

A paper published today in the Journal of Geophysical Research – Atmospheres finds “most climate models from the [IPCC] archive simulate a decrease in Antarctic sea ice area over the recent past,” however, “average Antarctic sea ice area is not retreating but has slowly increased since satellite measurements began in 1979.” Further, the authors find the latest [...]

A paper published in Nature Climate Change finds prior temperature reconstructions from tree-rings “may underestimate pre-instrumental [pre-1850] temperatures including warmth during Medieval and Roman times.” Many reconstructions show temperatures during the Medieval and Roman periods were warmer than the present, and this study suggests they were even warmer than previously thought. From the latest NIPCC Report:  Tree-ring [...]

In a new report entitled “Why was the start to spring 2013 so cold?,” the chief of the UK MET Office now admits that decreased Arctic sea ice or “Arctic amplification” was not responsible for the unusually cold spring 2013 in Europe, finding “little evidence from the comparison between the cold spring of 1962 and this [...]

Since the slowdown in surface warming over the last 15 years has been a popular topic recently, I thought I would show results for the lower tropospheric temperature (LT) compared to climate models calculated over the same atmospheric layers the satellites sense.
