I was alerted to an article on climate change in Mongolia which claims that temperatures there have already risen by more than 2C since the 1940s. A few minutes on Climate Explorer allowed me to check. Continue reading Temperatures in Mongolia

How "weird" has UK weather been in 2012?
A recent article on the BBC website said:
The UK has experienced its “weirdest” weather on record in the past few months, scientists say.
The question today is then, is this true? Continue reading How "weird" has UK weather been in 2012?
A 150 year temperature history from Berkshire
At a recent weather festival, Roger Brugge presented a reconstruction of temperatures from 1863 to 2011 for a small patch of the UK, namely Berkshire, which I found interesting. Continue reading A 150 year temperature history from Berkshire
The value of old weather observations
Previous posts have described some initial analysis of the data from the Old Weather project, which is using public volunteers to digitise new historical weather observations from Royal Navy ships during World War 1. The good news is that these observations will improve our knowledge of the atmospheric circulation. Continue reading The value of old weather observations
Reconstructing Atlantic atmospheric variability
In a previous post I discussed the Old Weather project which is using volunteers to transcribe the hand-written weather data from Royal Navy ships logs in the World War 1 period. The good news is the first 243 ships have been completed (providing data scattered throughout the period 1914-1923), and some simple analysis shows whether this data can help reconstruct past Atlantic atmospheric variability. Continue reading Reconstructing Atlantic atmospheric variability
Learning about past climate from ships logs
Understanding the climate of the past is extremely valuable to help put modern weather observations into a long-term context. Although we have considerable records of past weather, especially over land, more data is always welcome. Given the British obsession with the weather it is perhaps of no surprise that more data is available, it is just buried in hand-written logbooks. Transcribing this data is normally a time-consuming and expensive task…. Continue reading Learning about past climate from ships logs
A brief history of early climate science
Something a little bit different for this post…. After all the recent controversy over hacked emails, IPCC errors and the British public apparently growing more skeptical about climate science and scientists, it is perhaps interesting to take a step back and look at why we believe that emissions of various gases can influence our climate. Continue reading A brief history of early climate science
