Global warming is melting the world’s glaciers and sea ice. In Iceland the effects can already be seen – people there recently held a funeral to mark the death of the Okjokull glacier. So scientists and engineers around the world are trying to come up with ideas to cool the planet and stop the ice from melting. One wants to spray sea water into clouds to make them whiter so they reflect more of the sun’s rays back up. Another plan is to make sea ice more reflective by spreading layers of tiny silica beads on it. Others are devising massive geoengineering projects, such as building giant sun shades in the sky and walls around sea ice to stop warm water wearing it away. But sceptics warn that projects like these are too expensive and are a distraction from the cause of the problem – and we should be focusing on reducing greenhouse gas emissions instead.

The tiny New Jersey hamlet of Money Island sits perched on a low-lying stretch of the bay’s shore, where an inch of sea level rise can submerge roadways and flood foundations. In the past decade, beset by rising seas and increasing storm damage, many residents of Money Island and other nearby bay communities have opted to take buyouts from the state and abandon their homes. This Yale Environment 360 video explores homeowners’ agonizing decision over whether to stay or go, and the profound impacts this retreat is having on one of the poorest parts of New Jersey.
Governments are planning to produce about 50 percent more fossil fuels in 2030 than would be consistent with limiting warming to 2°C and 120 percent more than would be consistent with limiting warming to 1.5°C.
Countries will have to increase their carbon-cutting ambitions five fold if the world is to avoid warming by more than 1.5C, the UN report says. The annual emissions gap report shows that even if all current promises are met, the world will warm by more than double that amount by 2100.

The United Nations says greenhouse gas emissions surged to record-high levels last year. The new report also says that the increase in methane levels in 2018 was the highest increase in the last 20 years. Methane is an extremely powerful greenhouse gas. This is the World Meteorologist Organization’s secretary-general, Petteri Taalas.
Petteri Taalas: “And last year, we have seen emissions growth continued, it has been growing for the past two years and the estimate for last year was 2.1 percent increase. So, despite of Paris agreement, the emissions are still, still growing.”
Welcome to Transition Studies. To prosper for very much longer on the changing Earth humankind will need to move beyond its current fossil-fueled civilization toward one that is sustained on recycled materials and renewable energy. This is not a trivial shift. It will require a major transition in all aspects of our lives.
This weblog explores the transition to a sustainable future on our finite planet. It provides links to current news, key documents from government sources and non-governmental organizations, as well as video documentaries about climate change, environmental ethics and environmental justice concerns.
The links are listed here to be used in whatever manner they may be helpful in public information campaigns, course preparation, teaching, letter-writing, lectures, class presentations, policy discussions, article writing, civic or Congressional hearings and citizen action campaigns, etc. For further information on this blog see: About this weblog. and How to use this weblog.
