Huge congratulations to SMURPHS PI, Professor Piers Forster who has been appointed to the Committee on Climate Change (CCC) by the Minister for Energy and Clean Growth, Claire Perry MP, and the devolved administrations. Piers has played a significant role authoring Intergovernmental Panel on Climate Change (IPCC) reports, and currently has a coordinating lead author role for the IPCC sixth assessment report. As well…
The Atlantic meridional overturning circulation (AMOC) is a large, basin-scale circulation located in the Atlantic Ocean that transports climatically important quantities of heat northward. It can be described schematically as a northward flow in the warm upper ocean and a southward return flow at depth in much colder water. The heat capacity of a layer…
Researchers have traced large and long-standing biases in computer simulations of climate, affecting the turbid Southern Ocean, to errors in cloud that emerge rapidly within the atmospheric models. Biases evolve over time through knock on effects that shift the location of the battering winds of the “roaring 40s”. This new method combines detailed simulations with…
New research from the University of Southampton and the Laboratoire d’Océanographie Physique et Spatiale suggests that the average temperature of Earth’s atmosphere and oceans will be abnormally warm, beyond the Long-Term Global Warming Trend, over the next five years. A new method for predicting mean temperatures, suggests that the next few years will likely be…
Dr Dan Jones At the British Antarctic Survey lead research into natural processes that can rapidly inject heat and carbon into the interior ocean.  It can remain there for decades to centuries, potentially slowing global surface warming. One of these locations is the Labrador Sea, which features strong exchanges of heat with the atmosphere and exceptionally deep…
New research publication lead by Dr. Ramiro Checa-Garcia, from the Department of Meteorology at the University of Reading. Radiative forcing is a key concept used in climate science to ascertain the strength of different agents,  in driving climate change. In this context, ozone is recognized as one of the main contributors to radiative forcing according…
This article, co-authored by SMURPHS researchers Prof. Mat Collins and Dr. Jules Kajtar, sheds light on the diminished Atlantic-Pacific connection in global climate models In recent decades, the Pacific trade winds strengthened to levels never seen in the observational record. This strengthening has been associated with the early twenty-first-century slowdown in global surface warming. Although climate models could…
In this new study, led by SMURPHS Co-Investigator Florian Sévellec, researchers looked at how melting Arctic sea-ice leads to a weakening of the Atlantic Meridional Overturning Circulation (AMOC), the ocean system responsible for the transport of heat from the Equator to high latitudes.   The study demonstrates that positive buoyancy anomalies, resulting from increased ocean…
A new study led by SMURPHS researcher Jules Kajtar, published in Climate Dynamics, concludes that the variability of decadal trends in Pacific wind stress is under-represented in CMIP5 coupled models. The strengthening of the Pacific trade winds in recent decades has been unmatched in the observational record stretching back to the early twentieth century. This…
