Annual ice loss in Greenland is bigger than previously thought

It has been known for some time that the annual ice loss during the seasonal melt in Greenland was large, but new calculations revel that it is even bigger than previously thought. The challenge of working out just how big that ice loss is has lacked data because nobody is there on the ground at key sites taking measurements. One solution to answering this is to examine the Glacial isostatic adjustment (GIA). The what? If you pile a lot of ice on […]

Huge leap forward for Paris agreement on Climate Change

Last Wednesday, 21st Sept, the ratification of the Paris Agreement on Climate Change leapt boldly towards coming into force. We are not quite there yet, but it is a lot closer. I was blogging about this a few days ago, and so this was something I did anticipate. At the time the expectation was that another 20 nations would confirm that they had bound themselves within their legal frameworks to adhering to the Paris Agreement, and so those 20 would, when added […]

#Arctic melt season is probably over, how did it go this year?

The above diagram says it all really, 2016 was the second lowest on record. It was not and is not a typical year by any measure because globally each and every single month has broken all previous records for that month and so it comes as no great surprise to observe that the Arctic ice melt is well below the average, but not as low as that most astonishing of melt years, 2012. Looking back across each and every year, […]

California extends most ambitious climate change law in US

About ten years ago back in 2006 the state of California took the very bold step of passing legislation that was designed to slash their greenhouse emissions. This was Assembly Bill (AB) 32- California Global Warming Solutions Act of 2006 and was passed with the aim of establishing a comprehensive program to reduce greenhouse gas emissions from all sources throughout the state. It has been a huge disaster and has decimated the statewide economy … oh wait, no it hasn’t. The California Air Resources Board (CARB or ARB) advises that it […]

Climate Change: Huge leap forward for Paris Agreement on 21st Sept 1

As you are no doubt aware when it comes to addressing climate change the Paris agreement is not a done deal. Currently, there are 180 signatories to the Paris Agreement.  Of these, only 27 States have also deposited their instruments of ratification, acceptance or approval accounting in total for 39.08 % of the total global greenhouse gas emissions. Signing is simply ink on paper and can be happily ignored. Ratification is something quite different, it means that the nation ratifying is […]

Climate Change: xkcd nails it with one graph

Last Month I reported that July 2016 was the Hottest July ever in human history. Now that we have the raw data for August, we can take a peek and see if it is following the ongoing trend. So is it? Yes, it very much is. OK, so I was being a tad dramatic last month when I used the qualifier “ever in human history”. The precise definition is that it is the warmest since we started recording precise numbers each and every […]
