Visualization of methane emissions from cattle

A new imaging technique, developed by a team led by  Dr Magnus  Gålfalk at the Linköping University in Sweden and described in Nature Climate Change, allows us to see for the first time where it is being generated.  The video shows methane emissions (shown in purple and green) escaping from a vent in barn of housing 18 cows. This is a major step forward in our management of greenhouse gas emissions from landfill, agriculture, wastewater treatment and any other potential source of the gas.

Action Day at COP21 - Today everyone is invited to start taking action to control global warming

Today is Action Day at COP21 in Paris.  Today everyone is invited to start taking action to control global warming. http://bit.ly/1TrKg2F http://bit.ly/1lCjXMi

Our book Facing up to Global Warming: What is Going on and How You Can Make a Difference? published by Springer and launched for COP21 by Professor Nick Gray of the Trinity Centre for the Environment explores what global warming is, how it affects climate and importantly how we can deal with.  It is a challenge that everyone needs to be a part of. So on this day of action make a pledge to do your part to reduce greenhouse gas emissions by examining how you can minimize waste without compromising how you want to live.

Follow COP21 live

This year the UN climate talks (COP21) are taking place in Paris from the 30th November to 11th December. The aim is to achieve a legally binding and universal agreement on climate with the aim of keeping global warming below 2 degrees C. There will be an estimated 50,000 participants including 25,000 official delegates. For those attending the aim is to stimulate interactions during the conference between the negotiators and representatives of Civil Society. Of course the remaining 7 billion of us won't be able to attend the conference, but thanks to the UN we will be able to follow the conference live at  http://unfccc6.meta-fusion.com/cop21/

90% of seabirds have consumed plastic

Our litter and waste has reached a new level of disbelief with a new study showing that upto 90% of seabirds will have ingested plastic items they have mistaken for food.  A report in the Guardian has highlighted their work link.  Their results can be seen in the Proceedings of the National Academy of Sciences.

We still haven’t learnt as our production of platics in the past 11 years exceeds the amount produced since it was first produced  in the 1950s.But something is being done and new a new collection boom is hoping to start removing larger material soon.

You can help right now by picking up litter that will find its way eventually into the sea.

Major Greenland glacier victim to global warming

A NASA funded project has identified that the massive Zachariae Isstrom, that represents 5% of the total Greenland ice sheet, broke loose from a stable position in 2012 started a phase of  accelerated retreat. The glacier drains ice from an area of 35,440 square miles (91,780 square kilometers), that is enough water to raise global sea level by more than 18 inches (46 centimeters) if it were to melt completely. The bottom of Zachariae Isstrom is being rapidly eroded by warmer ocean water mixed with growing amounts of meltwater from the ice sheet surface. Currently it is now losing 5 billion tons of ice and water every year into the North Atlantic Ocean. Jeremie Mouginot, an assistant researcher in the Department of Earth System Science at the University of California, Irvine who has published this study in Science says that the result of this glacier breaking up and calving high volumes of icebergs into the ocean, will result in rising sea levels for decades to come. Full report Link

Adjacent to this is another large glacier Nioghalvfjerdsfjorden which is melting at a slower rate, but together they make up 12% of the Greenland ice sheet, so together they will raise sea levels by more than 39 inches (99 centimeters) if they completely melt.

NASA has a new project - Oceans Melting Greenland- which is monitoring ocean conditions around Greenland. https://omg.jpl.nasa.gov/portal/

World Food Day

Today is World Food Day which highlights the urgent issue of chronic hunger and promotes positive action through events in some 150 countries.  Follow the action on the web or  on Twitter

About 795 million people are undernourished globally, down 167 million over the last decade, and 216 million less than in 1990–92. The decline is more pronounced in developing regions, despite significant population growth. In recent years, progress has been hindered by slower and less inclusive economic growth as well as political instability in some developing regions, such as Central Africa and western Asia.
