In conclusion, the analysis tells me that, once the thermometer was kept in the jar the friction of the heat from the sun to the jar made the temperature heat up more inside the jar which resulted in the temperature of the thermometer to rise. On the other hand the thermometer which was not in the jar rose by one or two degrees or dropped by one degree. Though, this all comes down to the survey of the weather conditions.

This assignment explains clearly how the temperature in thhe jar is connected to how the green house affect warms the Earth. As explained, the sun’s heat hits the green house which causes the surface of the Earth to heat up. From this the ozone layer is killed from the Heat, Gasses and pollution on our Earth.

The First Antarctic explorers….

Filed under: Uncategorized — namratha at 1:31 am on Monday, March 2, 2009

Roald Amundsen was the first man to lead a successful expedition to the South Pole. Famously arriving about a month before Scott and his party that set out at around the same time. Amundsen used dog sleds, his party was well organised and well prepared with the primary intention of reaching the pole, rather than other exploration or scientific discovery.

This is Roald Amundsen:

 

When eventually Amundsen and his team set off, there were 8 men with sledges, pulled by 86 dogs. The first attempt was halted by the weather that became much colder than expected forcing the team to return to the winter base.

In the end a team of  5 men set off each with a sledge pulled by 13 dogs. They made good progress feeding the dogs on seal meat and blubber that had been brought with them. The men’s rations were meagre in quality, but sufficient in quantity.

Plans were made for the final push to the pole based on setting out with dogs that would be systematically shot and fed to the remainder. They struggled on against poor weather, blizzards and bad snow conditions which took their toll on both dogs and men.

 The party finally arrived at the South Pole. They had been concerned that Scott may have beaten them to the prize. They erected a small tent and placed inside it a letter and then set off back to their winter base. They arrived 39 days later with all five men and 11 dogs . The party that had reached the South Pole first.

 

So what happened to Scott ???……. This is Robert Scott

 

The ship  was built especially for this expedition, a wooden sailing ship with auxiliary engines. She was 172 feet long, 34 feet wide and was 485 tons unladed. She left Dundee where she had been built on July 31st 1901 sailing south to Antarctica.

Amongst the crew on this expedition was Ernest Shackleton engaged as third lieutenant in charge of holds, stores, provisions and deep sea water analysis.

On reaching Antarctica and after some initial explorations along the coast, the Discovery made its way to McMurdo sound where winter quarters were to be established. Many trips were made by manhaul and dog sledge parties in the remaining months before winter darkness fell. Scott and his men engaged on a very steep and uncomfortable learning curve in an unforgiving environment, a “school of hard knocks” and cold knocks too.

The expedition was made of many “projects” both scientific and exploratory performed by various combinations of the personnel. The centrepiece of the expedition was an attempt to reach the South Pole or at least to explore further South than anyone had managed to do previously. The core party was of Scott, Wilson and Shackleton supported by others who were to lay food and supply depots for the team to use particularly on the return journey. In this way the men would only need to carry enough supplies as to last them as long as the next depot rather than for the whole outward and return journeys.

Though the party had dogs, they were not experienced in using them, the food brought for the dogs was incorrect and had gone bad. When the dogs began to get lame, and weak through the rigours of the environment and lack of food, instead of killing them and depoting the meat, the party pressed on with the dogs running behind as they became too weak to pull the sledge.

In addition to this, Shackleton began to suffer from the effects of scurvy and all of the men were suffering from a lack of food. Wilson, the doctor suffered from snow blindness and at one point hauled his sledge blindfolded. They turned back on December 31st 1902 having reached 82�17′S. They had travelled 300 miles farther south than anyone before them and were only 480 statute miles from the Pole. It took them just over another month before they reached their base, as Scott put it “We are as near spent as three persons can be”. They had been gone for ninety-three days and had covered 960 statute miles.

The expedition however continued. A support ship the “Morning” had arrived from New Zealand to bring extra supplies and exchange some of the personnel including Shackleton who was still recovering from the effects of scurvy. The Morning left again on March 1st 1903 leaving the party to another Antarctic winter and to carry on their scientific and exploratory work.

The “Morning” returned in 1904 this time accompanied by another ship the “Terra Nova”. The government in England had decided that the Antarctic party might be having too good a time of it! relieved once a year by a hugely expensive relief ship and wanted them all brought back whether or not the Discovery had to be abandoned in the process.

For a while it looked like the Discovery might well be abandoned as there was 20 miles of ice between it and open water. With much hard work, explosives, the wind eventually in the right direction and finally the two relief ships breaking their way through the remaining ice, the Discovery was released and all three ships were under way heading back north.

Credit crisis

U.S. President George Bush announced that he will host a summit of world leaders in the near future to discuss the global financial crisis.

But he said that any financial reform should not come at the expense of democratic capitalism and free enterprise.

Bush made the announcement with French President Nicolas Sarkozy and European Commission President Jose Manual Barroso at Camp David and said it’s essential that world leaders work together.

The proposed Bush summit is expected to focus on ideas to prevent another financial-sector meltdown like the current credit crisis.

Sarkozy has called for an ambitious overhaul of the global financial system, as have other European Union leaders. The U.S. signalled before the meeting that the Camp David talks won’t create any new policy proposals.

World leaders have already held several meetings in North America and Europe over the past month to address the global credit freeze. Several governments, including the U.S., have passed massive multi-billion dollar bailout packages for their banking and financial sectors.

Despite the efforts, global stock markets have plunged several times since the crisis hit in mid-September. The TSX had a strong showing Friday to end on a high note after a rollercoaster week that saw stocks plummet, bounce back and drop again. The S&P/TSX composite index closed at 9,539.14, up 2.90 per cent.

But in the U.S., market volatility remained apparent at the close of the trading week. New York’s Dow Jones industrial average lost 127.04 points, closing at 8852.22 The Nasdaq composite index was down 6.42 points closing at 1,711.29 on Friday.

In his weekly radio address on Saturday, Bush said he expects the economy to “bounce back.”

Arctic Melt

BTN:Arctic melt

There is a video on my blog, Below

 Arctic Ocean sea ice is melting faster than even the most advanced climate change models predict, a new study concludes.

The work, published today in the journal Geophysical Research Letters, used the models to retroactively predict sea-ice decline from 1953 to 2006.

Scientists then compared the results to what has actually been recorded by Earth-based and satellite observations during that time frame.

The team found that, on average, 18 climate models used in a 2007 report by the Intergovernmental Panel on Climate Change (IPCC) underestimated the extent of sea-ice decline by a factor of three.

What are the chances of our little, cute polar bears?

Polar bear survival rates have dropped significantly in the past 20 years, probably due to melting sea ice caused by higher temperatures, according to a study released this week.The study, published by scientists from the U.S. Geological Survey and the Canadian Wildlife Service, found a 22 percent decline in the size of the western Hudson Bay polar bear population, from 1,194 in 1987 to 935 in 2004. The research also found that only 43 percent of polar bear cubs in the surveyed area survived their first year, compared to a 65 percent survival rate in the late 1980s and early 1990s.

The findings provide further evidence that polar bear may face a bleak outlook due to climate change.

Drowned polar bears are being found for the first time by researchers in Alaska, who speculate that greater distances between ice sheets could be taking a toll on the bears. While bears are capable of swimming long distances—up to 60 miles (100 km) without stopping—it is conceivable that they could suffer from exhaustion during an unexpectedly arduous swim.

The loss of ice also makes it more difficult for bears to find food. Unlike grizzly bears, polar bears aren’t adapted to hunting land animals like caribou, instead feeding primarily on seals. However, recent aerial surveys by the U.S. Fish and Wildlife Service show that, over the past five years, polar bears are changing their habits and spending more time on land, congregating on beaches and scavenging whale carcasses.

 

 

Caveman

Filed under: Uncategorized — namratha at 4:11 am on Sunday, September 14, 2008

Project:The history of man kind

In the past, many people shared the view of the 17th century people thought that the life of the human being without civilization was “…solitary, poore, nasty, brutish and short”. The modern scientific perception of prehistoric lifestyle is now that of the hunter-gatherer.

Caveman is traditionally portrayed as being clothed in animal skins, armed with bone or wood clubs, unintelligent, and aggressive. Furthermore, cavemen are often shown as living in caves; but this stemmed from the ritual paintings found in caves, where they are likely to be better-preserved than in more exposed locations. It is more probable that the caves were religious gathering places or temporary shelter, and not the actual dwellings of the supposed ‘cavemen’. Thus, expressions such as “Balrog” or “living in a hole” have become cultural metaphors for a modern human who supposedly displays traits of brutishness or extreme ignorance.
