The Future Of Energy
A new report by Bloomberg New Energy Finance takes a long-term look at the world’s energy production. According to the report, renewable energy, mostly in the form of solar and wind power, is set to provide close to 50% of the world’s energy by the year 2050.
Increasing Antarctic Ice Loss
Antarctica’s ice sheets contain enough frozen water to raise sea levels globally about 190 feet. Ice in the Antarctic is melting at a record-breaking rate and subsequent sea rises could have catastrophic consequences around the world. So, it is no surprise that scientists have been closely tracking ice loss in recent decades to understand both the current and future impacts of climate change.
Strategies For Limiting Global Warming
A new study published in Nature Energy shows that the goal of limiting global temperature rise to 1.5 degrees Celsius could be achieved by a combination of dramatic improvements in the energy efficiency of everyday activities.
Geoengineering And Developing Countries
There are some mind-boggling schemes being discussed to mitigate the global warming caused by greenhouse gases. These include placing giant mirrors in orbit to reflect sunlight before it reaches Earth and launching millions of tons of sulfur into the stratosphere to simulate the effects of a major volcanic eruption.
City Geometry And Urban Heat Islands
More than half of the world’s people now live in cities so understanding climate issues in cities is crucial. One of the most important city climate effects which has a profound impact on both human health and energy consumption is the Urban Heat Island Effect.
Sunshine To Fuel
Hydrogen is touted to be the fuel of the future, particularly for cars. But a more acccurate view of it is that hydrogen is an energy storage medium. And the most promising form of energy to store using hydrogen is solar energy.
The Automobile Future: Dream or Nightmare?
Visionaries tout a future in which cars are electric, self-driving, and shared. All three of these things are starting to happen today, but will they come together to produce a future where congestion and pollution are things of the past?

Carbon And Heating Soil
Plants are a critical part of the Earth’s carbon cycle. They take in carbon dioxide during photosynthesis. Eventually, dead leaves, branches and other materials fall to the ground where bacteria and fungi decompose the materials and release the CO2 back into the atmosphere. This carbon-soil feedback loop is a complicated one that is critical to the overall carbon balance because soils actually contain two to three times more carbon than the atmosphere.
‘Noah’s Ark’ Takes On Water
The Svalbard Global Seed Vault, built into a hillside in the Norwegian archipelago of Svalbard far above the Arctic Circle, is often described as humanity’s last hope against extinction after some global crisis. While there are more than 1,700 gene banks around the world that keep collections of seeds, all of them are vulnerable to war, natural disasters, equipment malfunctions, and other problems. Except the Svalbard vault – or so we thought. It has been dubbed the “Noah’s Ark” of seeds and a last chance for the world to regenerate if the worst should come to pass. It’s mission is to keep the world’s seeds safe.
Spray-On Solar Cells
One of the most exciting possibilities for future solar energy technology is that of solar cells that can be sprayed or printed on to surfaces like the windows of skyscrapers, the roofs of sports utility vehicles, or the walls of houses. And the expectation is that such technology would be far cheaper than today’s silicon-based solar panels.
Clean Energy In Massachusetts
Despite efforts by the new administration to increase support for fossil fuels, there is increasing momentum towards a clean-energy future. State and local efforts are driving the country to a 21st-century energy infrastructure, with or without the federal government.
Pesticides And Food Insecurity
A newly released report by the United Nations takes a strong stance against the use of industrial agrochemicals, saying that they are not necessary for feeding the world. The continued use of pesticides at the rate the world currently does in fact can have very detrimental consequences.
2016 Carbon Progress Report
Last year was a big year for progress in the U.S. power sector. Renewable energy provided nearly 17% of the country’s electricity, up from 13.7% in 2015. The first offshore wind farm in the U.S. opened off the coast of Rhode Island. And most significantly, carbon emissions from the power sector continued to decline and reached the lowest levels in nearly 25 years.
Clean Power Is Cheap Power
There are many good reasons why we should be making the transition from fossil fuel energy sources but the one that is likely to be the most persuasive is strictly economic. It has long been said that the renewable energy future will truly arrive when installing new solar panels is cheaper than a comparable investment in coal, natural gas, or other options.
Climate Change And Jobs
Combating climate change is a bit like treating a disease whose early stage symptoms are not very severe. People are not as motivated as they should be. Businesses have to comply with new regulations and spend money on new technologies, which seems like a losing proposition.
Is Coffee Endangered?
There are many worries related to climate change, notably the increasing occurrence of extreme weather events, melting polar ice, rising seas, and so forth. But perhaps one of the most ominous warnings comes from a new report issued by the Climate Institute about the future of coffee.
Japan’s Hydrogen Future
Japan is a country seeking energy independence as well as environmental credibility. It has grappled with nuclear disaster at Fukushima and is currently the sixth largest emitter of greenhouse gases in the world.
Ecology And Designing Future Cities
When most people hear the word ‘ecology’ – chances are it conjures up images of scientists working in distant, wild landscapes, such as old growth forests or remote mountain lakes. Increasingly, however, ecological studies are focused on urban and suburban areas.
