New study links carbon emissions and climate warming
December 2, 2014 07:44 AM - University of Southampton via ScienceDaily.

Research has identified, for the first time, how global warming is related to the amount of carbon emitted.

”čA team of researchers from the universities of Southampton, Bristol and Liverpool have derived the first theoretical equation to demonstrate that global warming is a direct result of the build-up of carbon emissions since the late 1800s when human-made carbon emissions began. The results are in accord with previous data from climate models.

The theoretical equation reveals the complex relationship between carbon dioxide levels and the ocean system. Burning fossil fuels increases atmospheric carbon dioxide levels leading to global warming and the greenhouse effect, which is partly offset by the oceans taking in both heat and carbon.

What Drives the Global Warming Debate?

Scientists have presented the most comprehensive evidence to date that climate extremes such as droughts and record temperatures are failing to change people’s minds about global warming. Instead, political orientation is the most influential factor in shaping perceptions about climate change, both in the short-term and long-term, said Sandra Marquart-Pyatt, a Michigan State University sociologist and lead investigator on the study.

Education is a key to climate change adaption

Given that some climate change is already unavoidable investing in empowerment through universal education should be an essential element in climate change adaptation efforts, which so far focus mostly in engineering projects, according to a new study from the International Institute for Applied Systems Analysis (IIASA).

The article draws upon extensive analysis of natural disaster data for 167 countries over the past four decades as well as a number of studies carried out in individual countries and regions, published last year in a special issue of the journal Ecology and Society.
 

Think Geoengineering is a quick fix for global warming?
November 26, 2014 09:20 AM - University of Bristol

The deliberate, large-scale intervention in the Earth’s climate system is not a “quick fix” for global warming, according to the findings of the UK’s first publicly funded studies on geoengineering.

The results of three projects – IAGP, led by the University of Leeds; SPICE, led by the University of Bristol; and CGG, led by the University of Oxford – are announced at an event held at The Royal Society, London, on 26 November.

Climate change, species extinctions and tipping points
November 25, 2014 07:35 AM - North Carolina State University via EurekAlert.

Researchers from North Carolina State University have created a model that mimics how differently adapted populations may respond to rapid climate change. Their findings demonstrate that depending on a population's adaptive strategy, even tiny changes in climate variability can create a "tipping point" that sends the population into extinction.

Carlos Botero, postdoctoral fellow with the Initiative on Biological Complexity and the Southeast Climate Science Center at NC State and assistant professor of biology at Washington State University, wanted to find out how diverse populations of organisms might cope with quickly changing, less predictable climate variations. 

World Bank warns effects of warming climate now unavoidable

As the planet continues to warm, heat-waves and other extreme weather events that today occur once in hundreds of years, if ever, will become the “new climate normal,” creating a world of increased risks and instability, a new World Bank study warns. 

The consequences for development would be severe as crop yields decline, water resources shift, sea-levels rise, and the livelihoods of millions of people are put at risk, according to a new scientific report released today by the World Bank Group.

Can Volcanic Eruptions Slow Global Warming?

Small volcanic eruptions might eject more of an atmosphere-cooling gas into Earth’s upper atmosphere than previously thought, potentially contributing to the recent slowdown in global warming, according to a new study.

Farms as sites for renewable energy
November 21, 2014 07:00 AM - ClickGreen Staff, ClickGreen

UK farms could be a major player in a shift towards a resilient, low-carbon energy system, according to a landmark report launched today by the Farm Power coalition. 

The coalition, which is made up of a growing number of farming bodies, businesses and NGOs, are now calling on policymakers and other key stakeholders, including supermarkets, to support the renewable energy vision.

The research carried out by sustainability non-profit Forum for the Future, which leads the coalition, and Nottingham Trent University, found there was at least 10GW of untapped resource across UK farms – equivalent to more than three times the installed capacity of the proposed new nuclear power plant at Hinkley Point C.

Not so fast: Planting trees might cause warming?
November 20, 2014 03:29 PM - Bristol University

Afforestation (planting trees) to mitigate climate change could cause warming rather than cooling globally due to non-carbon effects of land use change, according to new research from the University of Bristol.

Global land use change and its interaction with the climate system is recognised as an important component of the Intergovernmental Panel on Climate Change (IPCC)’s future climate scenarios.
