Less Carbon taken by trees in warmer climate, save Earth!

Save forests for this Beautiful Earth!

Contrary to conventional belief, as the climate warms and growing seasons lengthen subalpine forests are likely to soak up less carbon dioxide, according to a new University of Colorado at Boulder study.

As a result, more of the greenhouse gas will be left to concentrate in the atmosphere.
“Our findings contradict studies of other ecosystems that conclude longer growing seasons actually increase plant carbon uptake,” said Jia Hu, who conducted the research as a graduate student in CU-Boulder’s ecology and evolutionary biology department in conjunction with the university’s Cooperative Institute for Research in Environmental Sciences, or CIRES.
The study will be published in the February edition of the journal Global Change Biology.
Working with ecology and evolutionary biology professor and CIRES Fellow Russell Monson, Hu found that while smaller spring snowpack tended to advance the onset of spring and extend the growing season, it also reduced the amount of water available to forests later in the summer and fall. The water-stressed trees were then less effective in converting CO2 into biomass. Summer rains were unable to make up the difference, Hu said.
“Snow is much more effective than rain in delivering water to these forests,” said Monson. “If a warmer climate brings more rain, this won’t offset the carbon uptake potential being lost due to declining snowpacks.”
Drier trees also are more susceptible to beetle infestations and wildfires, Monson said.
The researchers found that even as late in the season as September and October, 60 percent of the water in stems and needles collected from subalpine trees along Colorado’s Front Range could be traced back to spring snowmelt. They were able to distinguish between spring snow and summer rain in plant matter by analyzing slight variations in hydrogen and oxygen atoms in the water molecules.
The results suggest subalpine trees like lodgepole pine, subalpine fir and Englemann spruce depend largely on snowmelt, not just at the beginning of the summer, but throughout the growing season, according to the researchers.
“As snowmelt in these high-elevation forests is predicted to decline, the rate of carbon uptake will likely follow suit,” said Hu.
Subalpine forests currently make up an estimated 70 percent of the western United States’ carbon sink, or storage area. Their geographic range includes much of the Rocky Mountains, Sierra Nevada and high-elevation areas of the Pacific Northwest.
Study co-authors included David Moore of King’s College London and Sean Burns of the National Center for Atmospheric Research and CU-Boulder.

103 Years old Granny on “Facebook Highway” : World Record

Published

By

Super Gran Facebook

All grandparents are awesome, that is an undeniable fact of life. But some are more awesome than others, and Lillian Lowe ranks highly in my opinion.

How old is the oldest person you are friends with on Facebook? I’m guessing none will be as old as Lillian Lowe from Tenby in Wales. Because at 103-years-old, she is believed to be the oldest person in the world to use Facebook. Even more amazing is the fact she accesses the social networking site via her Grandson’s iPad.

Already known to her grandchildren as Super Gran, they have now re-nicknamed her Superhighway Gran after she joined Facebook despite being several generations older than the average Facebook user. At the moment Lowe has around 30 friends, mostly family, but with the story of her presence on the site spreading around the Web that is sure to rise. That is, at least, if she decides to accept the mountain of friend requests heading her way.

Lowe told Tenby Today:

It’s a wonderful way of finding out about things, but I must say it’s a dreadful time waster!

Her grandson Steve Lowe, who helped set her up on the site and who lends her his Apple iPad to check it regularly, commented:

What’s great about Gran is that she’s not afraid to take things on and is always willing to learn – she’s a great inspiration to us all.

Lowe is thought to be the oldest Facebook user in the world as the former holder of that title, Ivy Bean, sadly passed away earlier this year at the ripe old age of 104. Bean was also considered to be the oldest Twitter user as well, but though Lowe knows what Twitter is, she isn’t yet using the site. Give it time.

This may be a fun little story on the surface but actually it’s one that demonstrates age is no barrier to using technology and the Internet. The iPad, and tablets in general, could help older people take the plunge and begin to explore computers and the Web. And that is something I’d love to see happen more and more.

10 year old Mother in Spain- Courtesy 9 News

MADRID:  10 year old girl has given birth in southern Spain and  authorities are evaluating whether to let her and her family retain custody of the baby, an official said on Tuesday.

The baby was born last week in the city of Jerez de la Frontera, said Micaela Navarro, who is the Andalusia region’s minister of social affairs.

Navarro told reporters the father of the baby is also a minor, and both the mother and the baby were in good health. Her department declined to give further details , such as the sex of baby.

The father of the 2.9-kilo (6.4-pound) baby was 13 years old and had remained in Romania, she said, describing him as her daughter’s former boyfriend.

The young mother “is very well, very well, like the daughter who is very well and very pretty,” Olimpia was quoted as saying.

The 10-year-old, discharged after three days at a hospital in nearby Jerez where she gave birth, “is very happy with her daughter. This is a great joy. It is not a drama,” she reportedly said.

National daily said the number of births to girls aged under 15 in Spain had climbed to 178 births in 2008 from 80 in 1997.

Telenor Ad’s Disgracing and giving Disrespect to Women

Telenor - Applying Western Culture

Telenor’s new TV commercial ‘internet more” is based on disgraceful words used against women who form more than 51% of the population of Pakistan. Labeling a college girl as “Taza Hawa Ka Jhonka”, it shows the degradation of society as a whole. It is a source of resentment and an assault on sanctity of women for many believing in social values.

The misuse of technology i.e. mobile internet service has been promoted unethically targeting immature minds of college and school going students. Setting aside the responsibility as a corporate entity, telenor preferred immoral language to promote its services among present and prospective users across the country.

“Jisay Moqa Patay hi Talha Nain Kar Dya TAG” is an offensive street language used in Telenor’s advertisement against women. It’s an insult to one’s intelligence and need to be condemned widely.

Multinationals are expected to follow values that show respect to individuals. Whenever they derail from this, they not only offend their customers but also the larger community they operate in. They are least expected to pick the regressive parts of popular culture and give them a lease of life.

Media’s power to influence public opinion is on the rise in Pakistan. The spread of a message has been increased drastically with the coming in of private TV Channels. At this point of time commercial entities promoting goods and service must work with the highest sense of responsibility. Can Telenor avoid letting down those who are struggling for better gender sensitive society in Pakistan?
