stratospheric ozone). On the very long time scale tectonic activities which can cause changes in albedo are the key driver of climate change. The tectonics have had an impact on the levels of CO2 exchange between ocean, atmosphere and solid regions. Besides, volcanism often associated with tectonic processes has a big effect on climate change. Apart from emitting CO2, volcano erupts magma containing a large amount of SO2, which can create atmospheric H2SO4 aerosols.
Global warming is found to be caused by the greenhouse effect. The greenhouse effect has been described, by the US Vice President Al Gore, as the potentially most dangerous environmental problem facing mankind, with consequences second only to nuclear war (CS, What is the Greenhouse Effect?). The Green house effect is the process in which gases build up thermal energy in the atmosphere by absorbing infrared radiation (NS, p625). This process is naturally occurring, it has kept the earth warm enough for the humans to keep living. The earth is about 60% warmer than it would be without the greenhouse effect.
When water freezes, latent heat is also released, warming the air in contact with the forming ice. Latent heat plays an important role in the redistribution of heat on the surface of Earth, especially through evaporation in the tropics and subtropics and the subsequent precipitation in higher latitudes. Secondly the warm waters sets up a low-pressure region around Iceland, reaching over the Norwegian Sea. The Icelandic Low acts as an enormous whirlpool sucking in warm air from the subtropical regions on top of the Gulf Stream and sending much of the heat to Norwegian shores. The transport of heat by the warm ocean
Humans do things that create carbon dioxide which is one of the greenhouse gases that cause the greenhouse effect. The greenhouse effect is when gases like carbon dioxide become trapped in the atmosphere and trap incoming solar energy. That solar energy is then redirected in all directions thus, warming the entire planet and causing what we know as global warming. Global warming is a heating up all parts of the planet causing global climate changes. “A major international assessment of climate change…provides conclusive new scientific evidence that human activities are causing unprecedented changes in the Earth’s climate.” (IPCC Confirms, 2013).
The evidence of sea floor spreading was further supported by Vine and Drummond, who studied the magnetic pattern of the sea floor. They found that the Earth’s magnetic field changes over time, because as magma from the mantle rises to the crust it cools but the basalt will align to the field it cools to. It is also found that on either side of mid oceanic ridges there were symmetrical magnetic patterns, so suggesting that the ocean was created at the mid oceanic ridges and as new ocean floor cooled, it pushed the crust away. Both Hess and Vine and Drummond found evidence that is crucial to the explanation of how continental drift happened, and it is very important in the development of geologists understanding, however other people found evidence to support continental drift also. Dan McKenzie went on to further explain sea floor spreading, being able to explain why new crust was made at mid oceanic ridges.
Carbon dioxide is a heat trapping greenhouse gas. It gets “released through human activities such as deforestation and burning fossil fuels, as well as natural processes such as respiration and volcanic eruptions” (Global Climate Change: Key Indicators, 2014). An increase in carbon dioxide means more heat is trapped thereby raising the Earth’s temperature. Global surface temperature needs to also be monitored. Not just one area but globally!
With too many greenhouse gasses in the air, the earth’s atmosphere traps too much heat and light and eventually the earth get too hot and the temperature rises. This process of collective heat from the sun is called the greenhouse effect. Sometimes the temperature can change in a way that helps us. The greenhouse effect makes the earth appropriate for people to live on it. Without it, the earth would be freezing, or the earth would be extremely hot.
After reading these two articles I found out that there are a lot of similarities and differences bin these two articles. The greenhouse affect is a process by which thermal radiation from a planetary surface is absorbed by atmospheric gases, the gases we produce and put in the air everyday. Also they both had a plan for trying to get to know the future outcome of the weather due to past weather conditions. They find out from ash particles found in ice or measuring the sea level,seeing if it has risen from polar ice caps melting. One more similarity is the equipment they used to get the results for example they both used temperatureDetermining global warming effects on weather can be done in many different in these two articles I found that you can use ice or water.

Oceans play a vital role when it comes to climate regulation, but there has been an escalating change in the sea temperature over the last few decades which contributed to sea levels rising. Oceans act as carbon dioxide main stores and a proportion of the carbon uptakes are exported along the ocean carbon pumps. An increase in the sea’s temperature and ocean currents may lead to a decrease in the uptake of Carbon dioxide by oceans. The ocean chemistry has already been affected as we are facing ocean acidification- which impacts species such as corals and calcareous plankton, aquatic and land ecosystems and the biogeochemical cycles. 1.10) What is the effect of climate change on biodiversity in the oceans and on land?
