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.
The The Human Dynamics of Climate Change map has been created in a joint effort by scientists and policymakers and it shows how climate change could affect people all over the world by the end of the century if carbon emissions continue unabated.
The authors behind this study say that climate change has substantially increased the prospect that crop production will fail to keep up with rising demand in the next 20 years.
The Global Calculator is an open-source interactive tool allows you to explore all the options we have to reduce emissions through changing our technologies, fuels, land use and lifestyles up to the year 2050. It is funded by the UK Government’s International Climate Fund and the EU’s Climate-KIC, and has been built by an international team.
This book uses a decade of primary research to examine how weather and climate, as measured by variations in the growing season using satellite remote sensing, has affected agricultural production, food prices and access to food in food-insecure regions of the world.
This study in BioScience compares coverage of biodiversity and climate change in newspapers, scientific articles, and research funding decisions, and finds that climate change eclipsed biodiversity loss as a priority in the mid-2000s.
New official data from the European Union shows a 19.2 % reduction on GHG emissions on 1990 levels, suggesting that the union is within reach of its target to reduce emissions by 20% until 2020. Emissions fell by 1.3 % between 2011 and 2012, largely due to reductions in transport and industry and a growing proportion of energy from renewable sources. Italy alone accounted for 45 % of the total EU net reduction in emissions in 2012, largely due to lower emissions from transport and industry.
In the wake of the IPCC’s Working Group II report, Oxfam has published a briefing that focuses on the implications of climate change for food security and hunger.
This paper by Drew Schindell from NASA's ’s Goddard Institute for Space Studies looks at climate change trends and tries to explain the much publicised and contested slowdown in global surface temperatures since 1998.
Climate policy progress assessment concludes that many countries are advancing to cut emissions at a similar rate as the UK. A report by the Global Legislators Organisation (GLOBE international) argues that only a "handful of countries" have not yet engaged with climate change as a policy problem or fail to see it as a legislative priority. Analysing the climate legislation of 66 countries (together accounting for 88 percent of greenhouse gas emissions) it finds that 62 of them have a 'flagship law'. And contrary to commonly held perceptions, it is not just rich countries that are introducing laws to tackle emissions. Countries including Ecuador, Costa Rica, Mexico, China, Indonesia, Kazakhstan, and Kenya are also taking firm legal measures.
The Danish Council of Ethics has launched an English version of its report on the ethical challenges associated with bioenergy production. The “Report on bioenergy, food production, and ethics in a globalised world” considers the production of bioenergy in a situation characterized by several major global crises - energy, food, climate and natural resources. Some forms of bioenergy may be a tool in battling the energy crisis and the climate crisis. However, growing energy crops may compete with food production and nature for scarce resources and thereby counter solutions to the equally acute crises concerning food and natural resources. The main focus of the report is thus on the ways bioenergy competes with food production and nature for scarce resources. The Council focuses also on the values that determine the choice of strategy in regard to countering these four challenges and points out that ethical deliberations should be more made more explicit in political decision-making related to major global crises.
In this podcast video from The Centre for International Governance Innovation – CIGI, David Keith, Professor of Public Policy at the Harvard Kennedy School, discusses the controversy, risks and potential benefits of climate geoengineering. Keith offers a background on solar geoengineering before addressing common criticisms. He notes that while solar geoengineering doesn't fit into current preconceptions about how we manage climate change, a moderate solar geoengineering solution could be a powerful tool in slowing the effects of climate change while dramatic emission reductions can continue. Tune in for the full discussion to learn more about this fascinating topic.
The report One Planet Living – The case for Sustainable Consumption and Production in the Post-2015 development agenda, a collaboration between Beyond 2015, Bond for International Development, and BioRegional, argues that sustainable consumption and production need to be included in the post-2015 development agenda that will succeed the Millennium Development Goals.
