Coastal management strategies in the age of climate change
September 4, 2015 05:52 AM - ClickGreen staff, ClickGreen
Coastal decision-makers must move away from considering physical and economic forces in isolation to fully recognise and explain changes to coastlines, according to new research from Cardiff University.
The coastlines where we live, work and play have long been altered by people, but now researchers have investigated why developed coastlines change over time in ways that are fundamentally different from their undeveloped, natural counterparts.
Fighting explosives pollution with plants

Biologists at the University of York have taken an important step in making it possible to clean millions of hectares of land contaminated by explosives.
Trees improve pollution dispersion in cities
September 3, 2015 09:28 AM - University of Leicester
Trees in cities throughout the UK could be significantly improving the quality of the air we breathe by decreasing pollution levels for pedestrians, researchers from the University of Leicester have revealed.
Climate change mitigation needs more ambitious emissions reductions
September 3, 2015 05:44 AM - ClickGreen staff
The collective climate targets submitted by Governments to the UN will lead to global emissions far above the levels needed to hold warming to below 2°C, researchers at the Climate Action Tracker warned today.
The analysis by the consortium of four research organisations was released today in Bonn where Governments are meeting for the second to last week of negotiations ahead of the Paris summit on climate action.
Satellite Study Calculates Earth's Tree Count
September 2, 2015 01:47 PM - ClickGreen Staff, ClickGreen
A new satellite study has calculated that there are more than 3 trillion trees on Earth, around 422 trees for every person, although the number is believed to have dropped by 46 percent since the start of human civilisation. The Yale-led international research found the result of the tree count is around seven and a half times more than some previous estimates.
Ants - Pests or pest controllers?
September 2, 2015 08:55 AM - Jessica Ramos, Care2
While many are used to thinking of ants as pests (especially during the summertime), new research published in British Ecological Society’s Journal of Applied Ecology says not so fast. Ants are actually pest controllers. They’re efficient, sustainable and safe, and these little guys are making a big impact on our planet.
MIT study looks at benefits of acting on climate change
September 2, 2015 07:25 AM - Mark Dwortzan | Joint Program on the Science and Policy of Global Change, MIT
Since the 1990s, scientists and policymakers have proposed limiting Earth’s average global surface temperature to 2 degrees C above pre-industrial levels, thereby averting the most serious effects of global warming, such as severe droughts and coastal flooding. But until recently, they lacked a comprehensive estimate of the likely social and economic benefits — from lives saved to economies preserved — that would result from greenhouse gas emissions reduction policies designed to achieve the 2 C goal.
Now, a team of researchers from the MIT Joint Program on the Science and Policy of Global Change has published a study in Climatic Change that provides scenarios that climate scientists can use to estimate such benefits. The study projects greenhouse gas emissions levels and changes in precipitation, ocean acidity, sea level rise and other climate impacts throughout the 21st century resulting from different global greenhouse gas (GHG) mitigation scenarios. The scenarios include a business-as-usual future and one aimed at achieving significant GHG emission reductions limiting global warming since pre-industrial times to 2 C. Research groups convened by the U.S. Environmental Protection Agency have already begun using the MIT projections to evaluate the benefits of a 2 C emissions reduction scenario for agriculture, water, health, and other global concerns.
Ocean plastic plague threatens seabirds
September 1, 2015 12:36 PM - Chris Wilcox, Britta Denise Hardesty & Erik van Sebille, The Ecologist
Already 60% of seabird species have plastic in their guts, often as much as 8% of their body weight. And with ocean plastic increasing exponentially, that figure will rise to 99% by 2050, threatening some birds' survival. Unless we act.
Climate Change will Cost Trillions
September 1, 2015 09:09 AM - Bill Roth, Triple Pundit
The economic ramifications of continuing the 20th century’s economic model, where unsustainable extraction and pollution conveys competitive advantage, are coming into sharp focus. Citigroup now projects a staggering $72 trillion global cost tied to man-made climate change during the 21st century.
Fossil of prehistoric sea scorpion discovered in Iowa!
August 31, 2015 10:16 PM - BIOMED CENTRAL via EurekAlert
The fossil of a previously unknown species of 'sea scorpion', measuring over 1.5 meters long, has been discovered in Iowa, USA, and described in the open access journal BMC Evolutionary Biology.
Dating back 460 million years, it is the oldest known species of eurypterid (sea scorpion) - extinct monster-like predators that swam the seas in ancient times and are related to modern arachnids.
