Showing results for: Climate trends/projections
Global trends of population growth, rising living standards and the rapidly increasing urbanized world are increasing the demand on water, food and energy. Added to this is the growing threat of climate change which will have huge impacts on water and food availability.
This paper presents biodiversity scenarios as a useful tool to help policymakers predict how flora and fauna will likely respond to future environmental conditions. Although changes to land use are a major driver of biodiversity loss, the study finds that scenarios focus overwhelmingly on climate change. The researchers argue that this imbalance makes scenarios less credible, and they make recommendations on how to improve and make more plausible projections.
As the climate changes, and food demand increases, crop varieties suited to these conditions need to be developed. The authors of this paper warn that crops yields around the world could fall within a decade unless action is taken to speed up the introduction of new varieties. They propose three ways to improve matching of maize varieties in Africa to a warmed climate: reduce the BDA (the process of breeding, delivery and adoption), breed under elevated temperatures and act to mitigate climate change.
In a recent blog-post on the UN’s Academic Impact website, Sonja Vermeulen and Andy Challinor write the third piece in a series on Food security and climate change entitled “Global Models Must Meet Grassroots Action to Deliver Climate Solutions for Farmers”.
The book provides an analysis of impacts of climate change on water for agriculture, and the adaptation strategies in water management to deal with these impacts.
This report by the USDA (United States Department of Agriculture) represents a consensus of more than 30 authors from 19 institutions across four countries. The report brings together modelling and forecasting research on climate change to the year 2100, and explores how these changes will affect food and agricultural systems worldwide, and in particular in the US.
This report by Ecometrica summarises the five key agreed outcomes of the recent 21st Conference of Parties (COP21) held in Paris and highlights their implications for businesses.
This paper presents evidence that humans are undoubtedly altering many geological processes on Earth—and that we have been for some time. According to the international group of geoscientists the evidence is overwhelming that the impact of human activity on Earth has pushed us into a new geological era, a human-dominated time period, termed the “Anthropocene.”
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.
