2018/10/26: A Vancouver Island home built using cutting-edge green technology is now move-in ready.
It’s called the “Harmless Home,” and the exterior walls are constructed out of Lego-like building blocks, made essentially of compressed hemp, lime and water.
Now, it’s being hailed as the most sustainable, safest and most energy-efficient house possible.
Home owner, Arno Keinonen recently settled in. “We are very happy with the end result,” he said.
The product itself is being manufactured in Calgary. It doesn’t mould and is virtually fire-resistant.
“We heat it up to over 1,500 degrees Fahrenheit and it barely has an impact,” said Just Bio Fiber builder Mark Faber. “Very unlikely for this house to catch fire.”
The blocks also absorb carbon, making the them grow even stronger over time. As for the cost, it’s in line with other alternatives.
“With those aspects and the condition the world is in now, this just has to go – it just hast to,” said Just Bio Fiber Director, Michael DeChamplain.
2018/10/09: Every scenario for keeping global warming under 1.5 degrees Celsius requires reducing per capita consumption. The scenarios range from shrinking world energy demand 15 percent by 2030 to constraining it to a 17 percent increase. Either way would mean less power for anyone rich enough to read this on a computer (if poorer people get more stuff under constrained growth, it means the richer people are going to have to make some lifestyle changes).
Some of this would come from efficiency, but it would also require “behavioural changes.”
Biofuel: Every scenario laid out by the IPCC relies on ethanol, biodiesel and other biofuels to some extent, and projects an increase in farmland devoted to growing fuel. We could really use biofuels to replace jet fuel and gasoline, but it’s controversial. There are good scientists who say corn ethanol has a bigger carbon footprint than gasoline. Others say burning ethanol is already carbon negative and getting better all the time. It seems impossible to tell who is right. If you are cutting down rainforests for palm oil, that’s definitely a climate catastrophe. If you can get algae in a tank to turn sunlight to fuel, well, that’s awesome.
Nuclear power: All scenarios have nuclear providing a greater share of our electricity through 2050. Right now, nuclear power provides 11 percent of the world’s electricity. In one 1.5 degree scenario, the IPCC report has the world doubling the percentage of electricity it gets from nuclear by 2030, and quintupling it by 2050. The most “degrowthy” scenario, with dramatically decreasing energy demand, doesn’t require building new atomic plants but does require keeping the ones we have open.
The Paris agreement on climate change charts a narrow path to avoiding a global apocalypse. Just one problem: Its centerpiece is a technology that basically doesn't yet exist.
Coal supplies over 40 percent of global electricity needs, and that percentage is going up. The only real question is how to minimize the damage.

Through burning fossil fuels, humans are rapidly driving up levels of carbon dioxide in the atmosphere, which in turn is raising global temperatures. But not all the CO2 released from burning coal, oil
Humans are pumping roughly 33 billion tonnes (36 billion tons) of carbon dioxide into the air each year. If all that showed up in the atmosphere, it would accelerate global warming even further. The ocean, however, absorbs around half of that CO2. Phytoplankton (essentially, microscopic plants) that live near the sea's surface take in a lot of it as they photosynthesize, ultimately flushing the CO2 into the cold, dense depths, where it stays trapped for centuries.
Beneath the lush forests of the Amazon is a whole different level of diversity that new research says may be one of the keys to understanding how to stem the global impacts of deforestation. The Amazon
We know that organic practices help reduce greenhouse gases -- but which practices, exactly, are doing the good work?
Carbon capture, for those who don't know already, is the term given to various different technologies that can "capture" the carbon dioxide in streams of gases that would normally be emitted to the atmosphere
Lo scorso anno i progetti per la cattura e il sequestro di anidride carbonica hanno raccolto 23,5 miliardi di dollari, esattamente la stessa cifra del 2010. Un rapporto del World Watch Institut ROMA - Il sex appeal del Ccs sembra essere svanito. Stando a un dossier realizzato dal World Watch
