The Long-Term Effect of Global Warming Will Change the World

This is 5 (five) consequences of global warming in the long-term :

" 1. Great Barrier Reef may be gone in 20 years

The Great Barrier Reef will be so degraded by warming waters that it will be unrecognizable within 20 years. Charlie Veron, former chief scientist of the Australian Institute of Marine Science, told The Times: “There is no way out, no loopholes. The Great Barrier Reef will be over within 20 years or so.” Once carbon dioxide had hit the levels predicted for between 2030 and 2060, all coral reefs were doomed to extinction, he said. “They would be the world's first global ecosystem to collapse. I have the backing of every coral reef scientist, every research organization. I've spoken to them all. This is critical. This is reality.

2. Amazon Rain Forest may turn into a desert

Teeming with millions of species and one-fifth of the world's fresh water, the Amazon is the world's largest tropical rainforest. However, global warming and deforestation are reversing the forest's role as a carbon sink, converting 30-60% of the rainforest into dry savannah. Projections show the forest could disappear completely by 2050.

3. Sahara Desert may become green

cientists are seeing signals that the Sahara desert and surrounding regions are greening due to increasing rainfall. If sustained, these rains could revitalize drought-ravaged regions, reclaiming them for farming communities. This desert-shrinking trend is supported by climate models, which predict a return to conditions that turned the Sahara into a lush savanna some 12,000 years ago.

4. Hurricanes may become more devastating than Katrina

It has not been determined whether Katrina was linked to global warming. But there are indications that global warming will produce more Category 5 hurricanes --and Katrina was only Category 4 when it hit Louisiana. Hurricanes derive their power in part from warm water, and so forecasting models show future hurricanes becoming more severe as sea surface temperatures rise. Global warming also makes hurricanes more destructive by raising the sea level, which leads to more serious coastal flooding. (According to the EPA, a two-foot rise would swallow a chunk of the U.S. bigger than Massachusetts.)

5. London may disappear underwater by 2100

It isn't only reefs and low-lying islands that are under threat from global warming. In fact, a major threat is for those large urban areas which are at risk of eventually being submerged underwater. This is caused by a change in sea levels that occurs when global warming takes place, resulting in coastal cities being destroyed by flooding. Dozens of the world's cities, including London and New York, could be flooded by the end of the century, according to research which suggests that global warming will increase sea levels more rapidly than was previously thought. London is one of the major world capitals at high risk of this type of flooding, as depicted in this shot from the 2007 movie Flood. Scientists say that the city could be under water as early as within the next one hundred years. "

464 Electronic Pump Control For Groundwater

Solinst (Canada) unveils their newly designed Model 464 Electronic Pump Control Unit. This tool is made to work easily with pneumatic pumps and obtain representative groundwater samples during monitoring programs such as site assessments, contaminant detection, site characterizations, remediation projects, compliance monitoring, etc. The Model 464 is designed to help field technician meet the sampling protocols of regulators worldwide, including the U.S. EPA. The Controller allows faster purge rates, as well as precise low flow control to ensure a representative sample at 100 ml/min or less when sampling for Volatile Organic Compounds ( VOCs ).
The Control Unit outputs 125 psi and runs on 4 AA alkaline batteries that can last up to 100 hours of normal use. The Model 464 also has a manual mode that allows user operate the Control Unit without batteries, using only a compressed air source.
These convenient boxes are rugged, dependable and suitable for all environments. Tubing is supplied and quick-connect fittings allow instant attachment to pumps, dedicated pump well caps, portable pump reel units and to an air compressor or compressed gas source.
The Control Unit is excellent to use with the company’s own model 407 Integra Bladder Pumps and Model 408 Double Valve Pumps. The Model 464 Electronic Pump Control Unit is available for purchase.

Emergency, Oil Reserves will be Exhausted within 90 years

Oil will run out within 90 years before alternative energy is found, according to new research from the University of California, Davis. These predictions were published online on November 8 in Environmental Science & Technology Journal. This research is based on the long-term theory, this theory said : investor is the best estimator to explain why and when alternative and renewable energy technology can be used.

"Our results show that takes a long time before alternative fuels that can be updated can survive, at least from a market perspective," said study leader, Debbie Niemeier, professor of civil and environmental engineering at the University California (UCLA), Davis.

Niemeier and team, Natalya Malyshkina one of Niemeier team's plans to create a new device that will help policy makers set targets are realistic about the resilience of the environment and evaluate the progress made to those goals. Two key research of this new theory is the capitalization market (based on share price) and dividends from oil companies owned by government and alternative energy companies. Other analysts have previously used similar equations to predict in finance, politics and sports.

Good investors tend to put great efforts in collecting, processing and understanding information relevant to future cash flows paid by these securities," said Malyshkina.
As a result, the market assessment in the future predictions represent the largest part of investors that tend to be relatively accurate.

Niemeier said the results of this latest study is a warning against the target of renewable fuels now are not ambitious enough in preventing the community, economic development and natural ecosystems harmed because of this.

We need a stronger policy support to encourage the development of replacement technology, "he said. We need a stronger policy support to encourage the development of replacement technology," Niemeier said.

Computer Recycling Green IT Expo in London, UK

Richard A Johnson recently attended the Green IT Expo in London. The aim of the conference? To showcase Green solutions to IT issues, most notably energy consumption and environmentally concious design. Here is Richards story when he attended the Green IT Expo

"Exhibiters at the conference ranged from Very PC, with their amazingly low powered desktop computers (24 watts per machine is more efficient than a laptop) to SIMMS recycling, a global recycler dealing directly with other mainstream recyclers. However, of most interest were the IT recycling companies present. As a representative in the same field, I thought it prudent to use them as a sounding board for issues I currently have with the UK's Computer Recycling industry. In effect, here's the conclusion that reflects every single recognised computer recycling company in the UK (IT-Green®, CDL, ICEX):

A combination of online marketing, Google Places and cheap (re-use) environmental licenses has given rise to small localised "recyclers" springing up throughout the UK. Potential business related clients are opting for the cheapest possible solutions when trying to recycle their computers and this in turn is leaving them open to the possibility of Brand damage, legal action and data security breaches. Recognised, professional recyclers have to of course maintain overheads that protect clients from the reality of security breaches and environmental protection and these simply are not in place with small operators that have been set up to take advantage of the WEEE directive. With less stringent environmental controls and reporting systems, those operating under section 50 exemptions are more likely to sell on waste electronics to exporters, who as highlighted by the Environment Agency have been assoiciated with organised crime.

As highlighted by Greenpeace in 2009, some 50 million tonnes of WEEE were dumped on developing countries and as I've said in previous posts, this is causing major problems, including deaths among children from lead poisoning......... "
