September 2017: New research study published in Nature Climate Change, ‘Arctic sea ice decline weakens the Atlantic Meridional Overturning Circulation

Thursday, September 14th, 2017

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 […]

June 2017: New publication, ‘Model under-representation of decadal Pacific trade wind trends and its link to tropical Atlantic bias’

Thursday, June 29th, 2017

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 […]

June 2017, new Nature article: ‘Strong constraints on aerosol–cloud interactions from volcanic eruptions’

Wednesday, June 28th, 2017

Recent research on aerosol-cloud interactions from volcanic eruptions will reduce uncertainty in climate model projections. An international team of climate scientists, including SMURPHS partners Reading and Leeds, studied the effects that the 2014-15 eruption at Holuhraun in Iceland had on cloud formations in the surrounding region, using this prolonged event to study how tiny aerosol particles […]

May 2017: SMURPHS Project-wide research meeting held at NOC

Wednesday, May 10th, 2017

In May 2017 we held the second, annual, project-wide research meeting. This two-day gathering of SMURPHS teams was held at the National Oceanography Centre in Southampton and was attended by researchers from all 9 partner institutions. The event was kicked-off with a keynote presentation by SMURPHS Adviser Professor Matthew England, Deputy Director of Climate Change […]

April 2017: Richard Allan publishes comment on warming slowdown in Nature Climate Change

Wednesday, April 26th, 2017

Global surface warming was slower than expected in the first decade of the twenty-first century. Might this have been due to ocean or atmosphere fluctuations as research suggests, or was it in fact due to something more subtle? In his ‘News and Views’ article in Nature Climate Change Principal Investigator (Reading), Richard Allan comments that, ‘ the […]

New publication: Surface flux and ocean heat transport convergence contributions to seasonal and interannual variations of ocean heat content

Monday, February 6th, 2017

The ocean plays a crucial role in the global energy budget as it is Earth’s primary heat reservoir on climate-relevant time scales. As such, variations in ocean heat content play a fundamental role in global and regional climate variability and the transient response to climate. In addition, ocean heat uptake is one of the major […]

New publication: Estimating changes in global temperature since the pre-industrial period

Thursday, January 26th, 2017

Defining ‘pre-industrial’ The UN Paris Agreement on climate change aims to ensure increases in global temperature are less than 2°C above ‘pre-industrial’ levels, with an aspirational 1.5°C limit. However, the ‘starting line’ of the pre-industrial era is not defined by the UN agreements, or by the Intergovernmental Panel on Climate Change (IPCC). A new analysis […]

New publication: Radiative forcing of carbon dioxide, methane, and nitrous oxide: A significant revision of the methane radiative forcing

Tuesday, January 24th, 2017

New, detailed, radiative transfer calculations of greenhouse gas radiative forcing have been performed by Gunnar Myhre (a SMURPHS External Partner at the Centre for International Climate and Environmental Research – Oslo) in collaboration with the University of Reading (a member of the SMURPHS consortium).  They show that the radiative forcing due to methane changes are […]

New publication: The rogue nature of hiatuses in a global warming climate

Tuesday, December 13th, 2016

Can the so-called hiatus be described as an unlikely rogue event? Recent research by SMURPHS teams at National Oceanography Centre (NOC) and University of Southampton has analysed surface air temperature from 20 climate models to estimate the historical and future likelihood of hiatuses and “surges”, and has shown that the global hiatus of the early […]

New publication: The contribution of greenhouse gases to the recent slowdown in global-mean temperature trends

Tuesday, September 27th, 2016

The extensive discussion of the nature, causes and even the very existence of the slowdown in the rate of global warming between the late 1990s and around 2010 has, surprisingly, paid little attention to the role of greenhouse gases (GHGs), the principal component of human-induced climate change. The results from a new study conducted by […]

Nature Climate Change: New use of global warming potentials to compare cumulative and short-lived climate pollutants

Tuesday, May 17th, 2016

In this latest study published in Nature Climate Change an international team of researchers, including SMURPHS Investigators Keith Shine and Piers Forster, considered how the choice of metric can affect the relative emphasis placed on reductions of ‘cumulative climate pollutants’ such as carbon dioxide versus ‘short-lived climate pollutants’ (SLCPs), including methane and black carbon. The research showed […]

Ed Hawkins: Spiralling global temperatures (1850 – 2016)

Monday, May 16th, 2016

Editor of the Climate Lab Book and SMURPHS Investigator, Ed Hawkins has created an animated infographic showing how global temperatures have increased from 1850 to the present day. This very powerful and effective visualization of global warming has attracted a global audience, not least on Twitter where it has gone viral. It has also been picked up by the wider media. In his […]
