The United States continues to go green – CO2 emissions near 1990 levels

CO2 emissions in US drop to 20-year low

In a surprising turnaround, the amount of carbon dioxide being released into the atmosphere in the U.S 다운로드. has fallen dramatically to its lowest level in 20 years, and government officials say the biggest reason is that cheap and plentiful natural gas has led many power plant operators to switch from dirtier-burning coal 다운로드.

Isn’t that great news?

I think we need some uplifting climate change news with all the “doom and gloom” stories out there 슬롯 머신 게임 다운로드. Let’s keep it going.

The United States has cut its CO2 output more than any other country in recent years, with our output dropping since 2007 eq두이노.  We are now close to 1990 levels and may be able to fit in with the Kyoto Protocols.

Of the fossil fuels, natural gas releases the least amount of air pollution and CO2 스포티파이 앱 다운로드. It is a homegrown source which improves our energy independence and stability, as well as keeping our money at home.

Coal has gone from producing half our energy to only one-third 다운로드.

Good news!

 

** Fracking for natural gas – it is unknown how destructive this new, hugely popular process is.

Our carbon sinks are absorbing twice as much carbon dioxide as they used to

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.

For more on this, check out The Economist article, That Sinking Feeling 로그레거시.

Crowdsource the launch of a nano-satellite into space – Kickstarter

We are developing a nano-satellite, and mobile apps to go with it, as the focus for a global education and public outreach campaign 다운로드. The satellite, called SkyCube, is a 10x10x10 cm “1U” CubeSat intended for launch as a secondary payload on a SpaceX Falcon 9 rocket in 2013 자백 14 다운로드. Orbiting more than 300 miles up, on a path highly inclined to the Earth’s equator, SkyCube will pass over most of the world’s inhabited regions 앵무새 다운로드.

SkyCube will take low-resolution pictures of the Earth and broadcast simple messages uploaded by sponsors. After 90 days, it will use an 8-gram CO2 cartridge to inflate a 10-foot (3-meter) diameter balloon coated with highly reflective titanium dioxide powder 여신의 키스 다운로드. SkyCube’s balloon will make the satellite as bright as the Hubble Space Telescope or a first-magnitude star. You’ll be able to see it with your own eyes, sailing across the sky 다운로드. But SkyCube’s balloon isn’t just for visibility. It will – within 3 weeks – bring SkyCube down from orbit due to atmospheric drag, ending the mission cleanly in a fiery “grand finale” that avoids any buildup of space debris 다운로드.

 

PLEDGES

$1 – Sponsors 10 seconds of the mission. You can broadcast one (1) 120-character message from the satellite 다운로드.

$6 – Sponsors 1 minute of the mission. You can broadcast six (6) 120-character messages from space, and request one (1) image from the satellite c920 드라이버 다운로드.

$100 – Sponsors 15 minutes of the mission. An ideal family pack – we’ll send you two (2) SkyCube mission T-shirts 프리 뮤직 다운로드! And you can broadcast one hundred (100) 120-character messages from the satellite, and request twenty (20) images from the satellite at any time during the mission ncs 학습모듈.

$1,000 – Sponsors 2 hours of the mission – a great high school or university classroom sponsorship package. We’ll send you a radio receiver which you can use to detect transmissions from SkyCube and other satellites already in orbit! You’ll also get a flying SpaceX Falcon 9 model rocket, and twenty (20) SkyCube mission T-shirts. You can broadcast one thousand (1000) 120-character messages from space, and request up to two hundred (200) images from the satellite.
