The term ‘carbon sink’ is becoming more common as we all gain the scientific education needed to deal with climate change and global warming 다운로드.
According to Wikipedia, carbon sinks can be both natural and artificial 다운로드. Both involve the process of absorbing carbon dioxide from the atmosphere, which is called carbon sequestration.
The main natural carbon sinks are the oceans and plants, and with our planet covered in so much water, the oceans are the biggest sinks on Earth 다운로드. The main artificial ones are landfills and the various carbon capture projects.
In those countries that follow the Kyoto Protocol, the use of artificial carbon sinks can serve as a way to offset other carbon use 다운로드.
Of course, as we are pumping more carbon into the atmosphere our natural carbon sinks are ingesting more carbon dioxide:
Nature has her own way of dealing with excess carbon dioxide 가톨릭성가 mp3. When human activities spew CO2 into the atmosphere, plants absorb more of it than usual, leading to profuse growth. The ocean, too, swallows more than it otherwise would g402. Many scientists fret that these so-called carbon sinks risk getting clogged up. Some even suggest that this has already started happening. – The Economist
Some even estimate that the amount of CO2 absorbed by the oceans and plants has doubled 다운로드. Nobody knows what this means, maybe it can continue and alleviate some of our carbon problems, or there could be a backlash effect.
It began with a frustrated blogpost by a distinguished mathematician 더 길티 다운로드. Tim Gowers and his colleagues had been grumbling among themselves for several years about the rising costs of academic journals.
They, like many other academics, were upset that the work produced by their peers, and funded largely by taxpayers, sat behind the paywalls of private publishing houses that charged UK universities hundreds of millions of pounds a year for the privilege of access 다운로드.
So, in January this year, Gowers wrote an article on his blog declaring that he would henceforth decline to submit to or review papers for any academic journal published by Elsevier, the largest publisher of scientific journals in the world 다운로드.
He was not expecting what happened next. Thousands of people read the post and hundreds left supportive comments. Within a day, one of his readers had set up a website, The Cost of Knowledge, which allowed academics to register their protest against Elsevier cs4 제품 다운로드.
The site now has almost 9,000 signatories, all of whom have committed themselves to refuse to either peer review, submit to or undertake editorial work for Elsevier journals 스케치업 한옥 다운로드. “I wasn’t expecting it to make such a splash,” says Gowers. “At first I was taken aback by how quickly this thing blew up.”
April 13, 2012 – Europe’s highest active volcano, Italy’s Mount Etna, erupted again this week 테라리아 pc 다운로드. The eruption, which spewed blood-red molten lava and grey and white ash into the air, is the 24th in a series that started in January 2011.
A decade ago the volcano was at it again, this time more serious 포토샵 cc 무료 다운로드. Several thousands residents were forced to evacuate. Tom Pfeiffer was there, 800 meters away in February 2000, during one of the eruptions and described it for us 슈가맨3 다운로드.
After a few minutes, the first red spots began dancing above the crater, rising and falling back into it 다운로드. The explosions grew stronger, first slowly, then with breathtaking speed, throwing bombs more than 1,000 meters above the rim. Soon the volcanic cone surrounding the crater was covered with glowing rocks 다운로드. At the same time, a fountain of lava started to rise from a fracture on the flank of the cone. Several other fountains rose from the crater and formed a roaring, golden curtain that illuminated the scene like daylight 비단체. Some larger lava bombs crashed into the snow not far from us, but we felt secure in our viewing position. The fountain was nearly vertical, and a strong wind carried the mass of glowing lapilli and ash gently away from us 웹쉐어 다운로드.
