The eyes of the world are set on Paris, as the COP21 climate summit started today with the ambitious goal of achieving a legally binding and universal agreement on climate, from all the nations of the world. But while this dance sometimes paces close to the impossible, there are also reasons to be optimistic: world leaders opened up with an unprecedented
More and more people are greening their homes, and that’s definitely a good thing – whether it’s renewable energy or green walls, it can not only save you a lot of money and reduce your carbon footprint, but also increase your home’s appeal and make it more cozy. The latest trend that’s picking up steam is moss walls – a
The wealthiest man in the world, Bill Gates, will announce on Monday a massive private-government partnership for a new clean energy research fund. This is reportedly the biggest research and development fund for clean energy ever, which will funnel billions to support innovation in this section. The precise details of the multi-billion partnership will be revealed once with the opening of the United Nations conference on climate change in Paris.
If you’ve heard the words “COP21”, “Climate Summit” or “Paris Climate… thingy” but don’t know what to make of them – this is what you need to read.
You know things are messed up when the head of the House committee that covers science doesn’t really understand it. Or, worse even, chooses to bury it and persecute scientists. Such is the case of Rep. Lamar Smith (R-TX), the chairman of the House Committee on Science, Space, and Technology, who suspects of fraud a group of scientists that explained in a new paper that the global warming hiatus isn’t actually thing. Seems like the world is warming at the same rate as in the 20th century – fast. That didn’t bode well with an obviously biased conservative Republican, so Smith subpoenaed the National Oceanic and Atmospheric Administration to gain access to the private documents and emails of scientists involved in the study.
Allan Cruickshank was a renowned National Audubon Society lecturer, photographer and author who co-published several books and field guides with his wife, Helen. Along with his cohorts–most notably bird guide author and illustrator Roger Tory Peterson—he transformed bird and nature watching from a fringe interest to a popular, easy accessible, mainstream pastime.
There’s an inherent flaw in solar cells: the metal wiring that’s quintessential to harnessing the electrons reflects the incoming light, acting like a mirror. Now, must people would brush off this issue and leave it like that. It’s a necessary trade off. But a team at Stanford University devised an elegant chemical technique that basically hides the wiring with silicon, away from the light while preserving energy harnessing. Metal wires cover 5 to 10 percent of a solar cell’s surface. Now, in the same area more light can be absorbed, hence more electricity generated which jumps the efficiency. Of course, this also means cheaper solar panels — if only the chemical technique is covered by the recurring costs of increased efficiency.
The Climate Summit in Paris may or may not create a binding agreement for countries to limit their greenhouse gas emissions, but either way, the real work will begin after the talks. “When the meetings in Paris are done, the real business of decarbonization must begin,” write climate-policy experts David Victor and James Leape in a Comment piece in this
Agriculture is a big driver of climate change, with the meat industry standing out among the rest as a source of CO2 emissions and environmental damage; lowering demand for meat or ensuring that farms have as little environmental impact is possible, but costly. Would you be willing to eat less, if it was for the good of the planet? Pay more for your meat? A new study suggests that the idea isn’t as controversial as you may believe on first glance.
Carbon dioxide levels in the atmosphere have never been higher: the average global CO2 levels have reached the 400 parts per million (ppm) milestone in the spring of 2015, The World Meteorological Organization (WMO) announced in the first week of November. Secretary-General Michel Jarraud warns that it won’t be long before even higher levels of the gas become a “permanent reality.”
