Paleoclimate is the climates of previous years of the earth’s history. The first way paleocimatologists study the earth’s past climates is by pollen. Pollen is sometimes trapped in lakes and bogs preserving it for many years. So when the scientist’s exstract the pollen they can see what type of plant it comes from. For example if they got the pollen from a silk tree they would know that that previous climate was a warmer one. Because silk trees need warm weather to grow. Then they count the number

the foot of the Athabasca Glacier‚ which is in the Columbia Icefield‚ the Athabasca River empties into the Peace-Athabasca Delta and Lake Athabasca. It then flows north as Rivière des Rochers‚ joining the Peace River to form Slave river‚ which empties into Great Slave Lake‚ which leads to the Mackenzie River into the Arctic Ocean. The beach that receives the deposited sediments is unnamed and near the city of Kittigazuit. Since the Athabasca River’s source is a glacier‚ it’s source is non-renewable

Geothermal heat is contributing to the melting of Thwaites Glacier. If the Thwaites Glacier was to collapse it could cause a significant rise in sea level between three to six

The evidence of these glacial and interglacial cycles was found in deep sea sediments. These large glaciers molded the land creating lakes and rivers in its path. The temperatures varied greatly between the glacial and interglacial periods. As research shows temperatures affect the wind and ocean currents. This in turn affects the amount of precipitation and dryness around the world. When the glaciers present a land bridge called the Bering Strait (Figure 1.4) between Alaska and Siberia revealed itself

A second idea supporting movement of the continents was the glacial till deposits in the southern hemisphere. With the continents in their present positions‚ the till deposits indicate erratic glacier motion. When the continents are fitted together‚ they show a much more streamlined motion of the glacier from southern Africa and Northern Australia outward. Why was the idea of continental drift not initially accepted by many other scientists and the general public at the time? Since his ideas challenged

"Extreme Ice" In this documentary film‚ “Extreme Ice‚” produced by PBS TV‚ 2009‚ James and scientists shows how glacier ice is melting. James Balog‚ a photographer‚ wanted to document and help scientists to understand mountain monumental changes. So he surveyed the ice and went to the places such as Alaska‚ Green land‚ etc. The project team which called “Extreme ice” discovered that there were very serious problems. The sun was the most reason of ice melting. But now‚ such as Industrial

Weisman brings up a good point stating “if we continue to increase our carbon emissions‚
