What is Quaternary science? Quaternary science is the study of glaciers changing, forming, and moving to lakes. Also involves sediments gathering at the bottom of these lakes and showing the climate change patterns overtime.

Climate Change The area of Earth science that David studies is climate change. Climate change is the way the Earth has changed its temperature over time. Weather & Climate change The difference between weather And climate. Weather is hourly or daily conditions people experience. Climate describes the average condition of temperature, humidity, cloudiness, precipitation, and other meteorological factors over for extended periods. Window to the Universe

Quaternary glaciation Quaternary glaciation is also known as Pleistocene glaciation. The Quaternary period dates back to over 2 million years ago (during the ice age), to the present. Ice sheets were formed in Antarctica and some in Greenland. One major effect of the ice age was erosion and deposition of the continents.

Quaternary glaciation helps us understand climate change Quaternary glaciation helps us understand climate change over the time from the ice age to the present. Quaternary glaciation created lakes, over time soil and dirt sediments collected at the bottom if the lakes. Scientists can collect samples of those sediments, study them and by the way the samples look they can con figure how climate has changed over the quaternary period.

What could Climate Change currently effect? What climate change effects today is: Sea level rising Arctic Sea ice is melting Glaciers and permafrost are melting Sea surface temperatures are warming The temperatures of large lakes are warming Heavier rain fall causing flooding in many regions Extreme drought increasing Crops are withering All of these also effect humans.

How water effects our climate the most The reason why scientists are so concerned about glaciers melting in the polls is that the more water in the atmosphere the warmer the Earth becomes. Water molecules heat the atmosphere directly by directly absorbing sunlight.

The next Ice Age Essentially what our Earth is leading up to with this climate change is another Ice Age, although scientists can’t be entirely sure. When the first ice age hit, the climate was slowly getting warmer then cooled an event that took thousands or years. What is happening today is our climate is increasing quickly over the last thirty years.
