  • Climate models may be overestimating the cooling effect of wildfire aerosols

    Original story at MIT News Whether intentionally set to consume agricultural waste or naturally ignited in forests or peatlands, open-burning fires impact the global climate system in two ways which, to some extent, cancel each other out. On one hand, they generate a significant fraction of ...

  • A model for health and climate change

    The impacts of climate change on human health are projected to be severe and widespread. A reliable model or software tool is needed to help quantify these impacts so that policies can be developed to mitigate against them. A recent report suggests that newly developed systems-based models need to be further expanded to allow greater quantification of climate-health relationships. Most research ...

  • OpenMI for climate modelling

    In a novel approach to represent the coupling between the land surface and atmosphere, DHI and DMI (Danish Meteorological Institute) are exploiting OpenMI technology to link hydrological and climate models. Modelling the effects of climate change on the hydrological cycle requires a proper understanding of the water and energy exchange between the atmosphere and the land surface. This exchange is ...


  • People matter in climate change models

    Climate change does not discriminate among regions or their inhabitants, but the continued growth of the human population will most likely contribute to the ill-effects of climate change. US researchers writing in the International Journal of System of Systems Engineering suggest an interdisciplinary approach, recruiting expertise from ...

  • New Discoveries Improve Climate Models

    New discoveries on how underwater ridges impact the ocean's circulation system will help improve climate projections. An underwater ridge can trap the flow of cold, dense water at the bottom of the ocean. Without the ridge, deepwater can flow freely and speed up the ocean circulation pattern, which generally increases the flow of warm surface water. Warm water on the ocean's ...

  • Piraeus Bank’s pioneering Climate Risk Management Model

    Piraeus Bank is the 2nd largest bank in Greece, with particular know-how in the areas of medium-sized and small enterprises, consumer and mortgage credit, green banking, agricultural banking (following the recent acquisition of ATEbank), capital markets investment banking, and leasing. During 2010-2012, Piraeus Bank ran the climabiz project (co-funded by the European Union through the financial ...

  • Japan is the ‘real world’ model for climate policy

    With the G8 set to meet in Italy this week, a report from a worldwide consortium of research institutes is arguing that the only policies that will work are those which focus on improvement in energy efficiency and the decarbonisation of energy supplies. The report, published by the Institute for Science, Innovation and Society at the University of Oxford and the London School of Economics and ...

  • Climate change models discussed at Lund conference

    More than 200 researchers from around the world are meeting this week in Lund to evaluate the recent development of regional climate models. These models have certainly been improved greatly in recent years; they can be refined further to provide even better support for the preparations we must make for future climate change. That climate change, very largely caused by ...

  • Climate change: what do models predict for Europe?

    Records show temperatures have increased in Europe – but what changes can we expect to see in the future? Experts at the European Environment Agency (EEA) have produced a series of maps showing projected changes in temperature and precipitation for this century. The maps have been produced in Eye on Earth, a global public information service which allows users to integrate many ...

  • Include trees in climate modelling, say scientists

    Current climate models and projections may be inaccurate because measurements are based on guidelines that do not include the effects of trees on the local climate, according to agroforestry experts. This in turn may be hindering effective ...

  • Global climate models `need regional sensitivity`

    Global climate change models are of limited use to agricultural policymakers in some regions of the developing world, according to a report by the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS). The report ...

  • Integrated models predict climate change impacts on biodiversity

    Predictions of the impact of climate change on biodiversity have tended to focus on changes in the quantity of suitable habitat. New research evaluates second generation models that combine population and climate data, setting out standards for their development. One of the 10 objectives of the EU Biodiversity Action Plan is to support biodiversity to adapt to climate change. Recently, there has ...

  • Australia First to Model Continental Shoreline Climate Impacts

    CANBERRA, Australia, August 23, 2007 (ENS) - The Australian government is undertaking to model the impacts of climate change on the whole coastline of the island continent. The project will help show the effects of storm surges, floods and tsunamis on Australia's coastal infrastructure, communities and ecosystems. Announcing the project today, Minister for the Environment and ...

  • Better infrastructure for continued development of climate models

    More complex climate models make great demands on a well-functioning computer environment. In a newly established EU project, SMHI is developing and simplifying collaboration between researchers by building up the infrastructure and support services for climate research. The climate models used to make calculations of the future climate are becoming increasingly advanced. They have higher ...

  • Ice core studies confirm accuracy of climate models

    An analysis of the global carbon cycle and climate for a 70,000-year period in the most recent Ice Age shows a remarkable correlation between carbon dioxide levels and surprisingly abrupt changes in climate. The findings, to be published this week in the online edition of the journal Science, shed further light on the fluctuations in greenhouse gases and climate in Earth’s past, and appear to ...

  • New approach to climate modelling considers delayed impacts

    Climate models usually assess the impacts of global warming at the time that the changes occur. However, the full effects of some impacts may not be seen immediately. A recent study is the first to examine these 'delayed' impacts and indicates they should be considered when defining 'harmful' climate change. Targets for mitigating climate change rely heavily on global climate models. Projections ...

  • Geomagnetic storm analysis to improve chemistry climate models

    Scientists from the British Antarctic Survey and the Space Weather Prediction Center in Boulder, Colorado, have shown that high energy charged particles that are usually trapped in the Earth’s magnetic field are released into the atmosphere at different locations during geomagnetic storms. The results will help to refine models of atmospheric chemistry and climate. A paper published this month in ...

  • Powerful replacement in works for climate-modeling computer

    One of the most powerful computers in the world dedicated to climate change, weather and other earth science research will be replaced in 2017 by an even faster machine, officials announced Monday. The Yellowstone supercomputer in Wyoming currently ranks among the 60 fastest in the world. The new supercomputer, to be named Cheyenne, will be at least 2 1/2 times more powerful, the National Center ...
