The certification organisation Rainforest Alliance states that scaled-up efforts to support climate-smart agriculture practices are desperately needed to support the millions of cocoa farmers that are suffering from the negative impacts of climate change.
WHO has released a first set of Climate Change and Health Country Profiles that provide a snapshot of up-to-date information about the current and future impacts of climate change on human health. The Climate and Health Country Profile project is an ongoing initiative that supports interested WHO Member States in finalising country profiles through a country consultation process.
This report entitled “Explaining Extreme Events of 2013 from a Climate Perspective” is the fourth in a series of annual reports published by the US National Oceanic and Atmospheric Administration. It provides an assessment of how climate change may have affected the strength and likelihood of individual extreme events.
This new report “Planetary Health: Safeguarding Human Health in the Anthropocene Epoch” launched by The Rockefeller Foundation - Lancet Commission argues that changing environmental conditions such as increased carbon dioxide emissions, rampant use of fertilizer and the acidification of the oceans could lead to major health challenges for millions of people. Increasing population, unsustainable consumption and production and the over-exploitation of natural resources are also factors straining the planet's resources and having an impact on human health.
Tracking intended nationally determined contributions (INDCs): what are the implications for greenhouse gas emissions in 2030? is the title of a policy paper produced by the Grantham Research Institute on Climate Change and the Environment and the ESRC Centre for Climate Change Economics and Policy at London School of Economics and Political Science. Parties to the UNFCCC agreed to set out their Intended Nationally Determined Contributions (INDCs) at the 20th Conference of the Parties (COP20) in Lima, Peru, in December 2014. The policy paper, which is intended to inform decision-makers in the public, private and third sectors, considers whether the INDCs submitted so far are consistent with the 2°C limit.
This report is the result of the work of a Taskforce of academics, industry and policy experts commissioned to examine the resilience of the global food system to extreme weather. The summary report is built on three detailed reports: Climate and global production shocks (Annex A); Review of the responses to production shocks (Annex B) and the Country-level impacts of global grain production shocks (Annex C).
The report concludes that the global food system is vulnerable to production shocks caused by extreme weather, and that this risk is growing. It suggests that climate change and a growing population will increase the likelihood of food "shocks" - where the production of staple crops such as rice, wheat and soybean fall by 5-7%, arguing that it will triple in likelihood in just 25 years. The preliminary analysis of limited existing data suggests that the risk of a 1-in-100 year production shock is likely to increase to 1-in-30 or more by 2040.
This report is the latest in The Lancet’s Commission on Health and Climate Change series.
The premise of this report is that tackling climate change could be the “single greatest health opportunity in the 21st century”. Climate change is described as a medical emergency that could undermine 50 years of global health gains and Richard Horton (The Lancet editor) states that this is the 'most ambitious and important Lancet Commission we have published'.
The chapters in the report are as follows:
In a survey carried out by the International Trade Centre, ITC exporters reveal widespread concerns about reduced competitiveness due to climate change. Based on surveys of exporting firms in both Peru and Uganda, the new publication, Climate Change and the Agri-Food Trade: Perceptions of Exporters in Peru and Uganda, identifies threats arising from climate change and seeks to develop solutions to help the agriculture sector adapt. The publication concludes that climate change makes existing challenges in the agri-food sector even more difficult to overcome, and argues that it is already having a highly negative impact on competitiveness.
This article from Nature Climate Change discusses a research project that investigates the impacts of both traditional and transitioning Indian diets on the climate. Funded by Wellcome Trust, the goal is to obtain a detailed picture of what people are eating throughout India and calculate both the climate and health impacts of different types of diets.
In this new paper researchers confirm that as carbon emissions continue to climb, so too has the Earth's capacity to absorb carbon dioxide from the atmosphere. About half of the emissions of CO2 each year remain in the atmosphere; the other half is taken up by the ecosystems on land and the oceans.
In this article from Scidev, Laurence Haddad (senior research fellow at the International Food Policy Research Institute and former director at the Institute of Development Studies) discusses the new Global Nutrition Report by the International Food Policy Research Institute (IFPRI).
This paper entitled The environmental impact of climate change adaptation on land use and water quality published in Nature Climate Change says that adaptation to climate change could have profound environmental repercussions, potentially generating further pressures and threats for both local and global ecosystems.
This paper describes how deep public divisions over climate change are unrelated to differences in how well ordinary citizens understand scientific evidence on global warming. Contrary to what many believe, members of the public who score the highest on a climate-science literacy test are the most politically polarized on whether human activity is causing global temperatures to rise.
This report sets out new climate change projections for Australia. It was produced by Commonwealth Scientific and Industrial Research Organisation (CSIRO) and funded by the Australian Government Department of the Environment, CSIRO and the Australian Bureau of Meteorology. The key findings from the report are copied as follows:
Though politicians and scientists have disagreed about whether atmospheric warming can be delayed by reducing short-lived climate forcing (SLCF) agents, an international research team has confirmed that a reduction in carbon dioxide emissions is the only long-term solution. Previously, politicians and industry had been pushing for measures to reduce SLCF emissions as a way to buy time before needing to address CO2 emissions directly.
A new study from researchers at The Earth Institute of Colombia University and the Woods Hole Research Center says emissions of nitrous oxide could double by the middle of the century if left unchecked. Nitrous oxide is the third biggest contributor to human-induced climate warming after carbon dioxide and methane.
In the recent annual report from the Global Carbon Project (GCP) we are warned that if emissions continue to climb at current rates, we will not be able to keep global warming to less than two degrees Celsius. The research suggests that if we wish to limit global warming (to 2 degrees) we will have to stay below 3,200 billion tonnes of carbon dioxide.
Concentrations of carbon dioxide last year grew at the fastest rate since 1984, says a BBC news article. Reporting on data released by the World Meteorological Organisation, the article describes how this increase in concentration is due not only to increased greenhouse gas emissions, but also to a reduced carbon uptake by the biosphere. This reduction could be temporary, or it could be an indication that the biosphere has reached its absorption limit. The article points out that seas, trees, and living things, which play an important role by absorbing over half of the total greenhouse gas emissions, are also breaking records; the oceans soak up about 4kg of CO2 per person every day, a rate unparalleled over the last 300 million years and resulting in unprecedented salination of the oceans.
