As a result of ecological migration of former inhabitants, the ecological condition in the reserve has experienced a 13-year-long recovery, transferring a desert into a green land. During this period, the number of species in the reserve has grown from 295 in 2000 to 366 today, with the protected area expanding from 7,200 hectares to 33,710 hectares. [Photo/Xinhua]

Large Increase In Arctic Ice In 2013 Summer

'Green shows areas of ice present in 2013, but not present in 2012. Red shows the opposite. The Beaufort Sea is the big problem for alarmists. In June 2012, wind opened it up early causing lots of solar energy to be absorbed and warming of the water. That didn’t happen this year, and with the sun starting its decline the opportunities for a big melt are getting slim.'

'There is no scientific consensus' on sea-level rise, say scientists

Just don't have enough data to say what'll happen
By Lewis Page, 15th July 2013
There isn't enough data to say with any certainty what will happen to sea levels around the world this century, and there is no "scientific consensus" to suggest that the rate of the seas' rise will accelerate dangerously.That's according to a group of eminent specialists based in Germany, the Netherlands and the UK. Writing in hefty boffinry journal Nature Geosciencethis week, the assembled experts have this to say:
The Greenland and Antarctic ice sheets have been reported to be losing mass at accelerating rates ... However, at present there is no scientific consensus on whether these reported accelerations result from variability inherent to the ice-sheet–climate system, or reflect long-term changes ...

[Our emphasis.]

The Greenland and Antarctic ice sheets are very important factors in forecasting the rate at which the seas might rise in the coming century, which is perhaps the primary reason to be concerned about global warming and associated climate changes.During the 20th century, sea levels as measured by tide gauges rose about 17cm, just short of 2mm a year. The most recent report of the Intergovernmental Panel on Climate Change said that "no long-term acceleration of sea level has been identified using 20th-century data alone", but the organisation nonetheless forecast rises in the 21st century of 26-59cm as many scientists think that the rate of rise will increase seriously due to global warming.Many others boffins assess that the ice sheets are so massive that they will take centuries to respond to likely levels of warming. Recent first-of-its-kind analysis pulling together all the factors in play suggested that the worst possible case in 2100 would be 30cm with the likely result less - in other words, no major change from the 20th century situation. And that was before new studies came out reflecting the fact that global warming has been basically on hold for the last decade and more, meaning that warming forecasts should be revised downwards.Be all that as it may, the next IPCC report is now being produced. It will attempt to reflect what the various committees and advisors believe to be the scientific consensus on various matters including sea levels. But it appears that there simply isn't any scientific consensus on the Antarctic and Greenland melt rates - and therefore there isn't one on sea levels either.You wouldn't necessarily know this. Various organisations, for instance the Google-funded alarmist activism organisation Climate Central, say that thereis a consensus and that it centres on a much higher figure - one or even two metres of rise by 2100. ("Scientists expect" this, we are told by the Google mouthpieces.)One of the authors of the new study today, Professor Jonathan Bamber of Bristol uni, carried out a previous effort to work out what scientists think sea levels will do, in which metre-range rises were described as "conceivable" but highly unlikely."Expert opinion is shown to be both very uncertain and undecided," that study said.The scientists compiling the new assessment say that there simply isn't enough data yet (especially from the GRACE satellites which have lately produced such surprising results on glacier and ice sheet mass) to know what will happen. In the case of the Greenland ice sheet, at least another ten years of data will be required.According to a Bristol uni statement released to highlight the research:

As a result, extrapolation of the current contribution to sea-level rise of the ice sheets to 2100 may be too high or low by as much as 35 cm. The study, therefore, urges caution in extrapolating current measurements to predict future sea-level rise.
IPCC drafters, take note. ®

Scientists make land arable again                                   Updated: 2013-09-16 01:53         By Cheng Yingqi ( China Daily)

The spread of sand in Xinjiang stops, and a major road to Urumqi is saved                          

For 2,000 years, people have battled the relentless wind and sand of the unforgiving TaklimakanDesert.Ancient civilizations along the Silk Road were swept aside, leaving traces of their existence onlyin the remains of temples and frescos.Qira county in the southwest of the Xinjiang Uygur autonomous region is one of the mostseverely hit regions.Without scientific methods to combat desertification, the march of the sands of time would havecontinued.But scientists have found an oasis of triumph after three decades.The Qira research station of the Chinese Academy of Sciences was established in 1983. With the help of the scientists from the station, a transitional zone was established, and gradually the sand was pushed back more than 5 kilometers. Jappar Mashrap, 49, lives in Qira and has witnessed the change and benefited from the work ofthe scientists.Mashrap’s endangered home was on the fringe of the desert and the family had to move in the late 1960s as the sand crept closer.But thanks to the work of the scientists, the desert’s march was stopped and Mashrap has ahome again.

"Now on Children’s Day, people often take their children to the amusement park, but things were quite different when I was a boy," Mashrap said.

"In those days, to celebrate festivals, my parents had to take me a long way to find grass where we could play.’’

The sand also threatened a major road running through on the north-south axis of the TaklimakanDesert.The 562-kilometer road, completed in 1995, shortens the route between Urumqi and Hotan by500 km. But it had been plagued by problems caused by the sand.Xu Xinwen, director of the station, and his team devoted much of their efforts to securing the road."Sometimes the sand on the road piles up a few meters high," Xu said. Various methods were tried, including fencing and barriers, but each had a drawback.

"The most effective barrier for sand is greening," Xu said.

However, in a desert that has annual precipitation of just 10 millimeters, "planting a tree and nurturing it to full growth is even more difficult than raising a child", Xu said.Xu found seeds and plants that can survive in the bitter salt water under the sand, such asChinese tamarisk, calligonum and Haloxylon ammodendron. Since 2003, 20 million drought-enduring plants have been planted along the road, forming a 72-to78- meter green belt.The plants are irrigated by underground water pumped up 114 water wells. Compared to the costof maintaining fences and barriers, irrigating the plants save some 30 million yuan ($4.9 million) every year.The discoveries and applications of the desert plants is a lengthy process, according to GuanKaiyun, director of the Turpan Eremophytes Botanic Garden."Our researchers working in the stations find the plants and seeds, and we are in charge of plantintroduction and acclimatization, which sometimes takes more than a decade to finish," Guansaid. In the parched Turpan Basin sits the world’s only botanic garden of Asian desert flora. When anew plant is found, the samples are usually taken back to the garden, where scientists find waysto help the plants adapt to the new environment. Spending four decades introducing and preserving desert plants, the botanic garden now has 700 different species, 50 of them endangered. Estimates put the number of plant species in thedesert at about 5,000.The plants also provide scientists with research opportunities.

One example Guan gives is Ammopiptanthus nanus, an endangered evergreen shrub in Xinjiangon which scientists recently extracted a protein that can combat deep cold."That protein explains the reason that Ammopiptanthus nanus survives the extreme lowtemperatures. And it’s worth further study because we might use it in genetically modifiedtechniques in the future," Guan said.Tian Changyan, deputy director of the Xinjiang Institute of Ecology and Geography, has devoted10 years to finding the perfect plants that could improve the saline-alkali soil.

"Some plants can only grow in excessively saline soil. If we cultivate these plants on moderately saline soil, the plants will extract the salt out of the soil and improve its fertility," Tian said.From 305 different salt-tolerant species, Tian identified six that were the most efficient.Experiments on a 67-hectare test field showed the plants were able to reduce the soil salt from 3percent to less than 0.6 percent within three years.

"Compared to the old method of washing the saline soil with water, the plants are much moreeffective and sustainable," Tian said.Scientists at the Xinjiang Institute of Ecology and Geography have devised a major project which could change the landscape forever. By 2020, the institute will build a gene bank of arid regional plants covering 10,000 plant species. Also, a world-class botanical garden is planned for IliKazak autonomous prefecture."The arid regional plants have excellent genetic features, so the genes are a significant strategic resource of the country," Guan said."The genes have great potential for our future development of agriculture, medicine and the military."

Yes......you can change deserts to green, .......
with a lot of care and water.........



Does that mean Morano cheese is best?
