For the forums in this class, we are going to engage in some "peer-learning." This is where you all not only get to ask questions, but also provide the answers to the questions! I will be around to make sure your responses are correct and on-topic. I will be looking for everyone to ask a question on a topic you may be struggling with, or you don't fully understand, or maybe want to confirm your understanding. Please make sure that your questions pertain to this week's lessons. Topics for this week include the following: climate zones, and climate change
Then respond to at least two other people's posts with an answer. Make sure you provide a thorough response! This will make sure you understand while helping someone out at the same time! A win-win for everyone! :)
Let me know if you have any questions about this!
-Post a question on a topic you are struggling with.
-Respond to at least two other people's posts.
Instructions: Your initial post should be at least 250 words. Please respond to at least 2 other students. Responses should be a minimum of 100 words and include direct questions.
Reading this weeks lesson I really don't have a thorough understanding of what microclimate is. Can someone please explain to me what a microclimate is? I know the definition states that is a climate near the surface in a small area such as the ground under a tree where atmospheric properties are fairly consistent. None of this makes sense to me at all. Can anyone help me out on this?
The Koppen classification system created by Waldamir Koppen (1846-1940) in 1918 identifies five major climate types using assigned letters A thru E. They are:
A= Equatorial: Tropical Moist Climate, this area is where tropical rain forest exist.
B=Arid: Dry climate, one important fact about this climate is the Atacama desert in South America has seen no rain for 400 years
C=Mediterranean: moist mid latitude climate, this climate brings mild winters
D=Temperate: moist mid latitude climate, that brings severe winters
E=Snow: Snow or tundra climate in the high latitudes of the northern hemisphere that bring extremely cold winters with short summers
E(f)=Polar:polar ice cap climate that has very cold winters and summers, the temperature never gets above 50 degrees and they never really have any summers, the artic ocean is usually frozen all the time.
Climate changes are occurring every day around us by the release of greenhouse gases some examples of this are the following:
Warmer oceans that lead to rising sea levels
Melting snow and ice the earth absorbs more energy that leads to changing conditions to plants and animals, this leads to shifting ranges and migration and habitat loss and extinction as well as changes in seasonal patterns
Evaporation leads to more precipitation in some areas and in others there are more droughts and wildfires.
These greenhouse gases effects the temperature and rate of evaporation in oceans. One could argue this does not effect our climate and global warming is only a myth not science, but its proven the more carbon dioxide released into the environment the more it effects our climate and the planet we live on.
Global warming not only effects our planet but it also effects our weather patterns. When we clear forests, release carbon dioxide into our environment at an alarming rate the earth will warm as a result of decreasing the amount of evaporative cooling that leads to rising temperatures.
Lesson Seven Climate and global climate change
This week’s topics are extremely important as I believe climate change to be one of the biggest challenges the world is facing at the present time. Climate change is caused by the increased production of greenhouse gases into the atmosphere, we have increased the carbon dioxide levels so much that soon they will surpass the levels during the ice ages according to scientists. They are higher now then anytime in the past 400,000 years. Climate change causes a lot of horrible affects in the world such as warmer temperatures and oceans, damage to coral reefs, and the possible extinction of certain animals. Additionally, future effects of climate change will include more frequent wildfires which I have personally witnessed where I live and caused many to evacuate and lose their homes. Droughts will also rise and there will be an increase in the number, intensity of storms.
According to NASA, in the Global Climate Change Department the regional effects in the US will be as follows:
Northeast. Heat waves, heavy downpours and sea level rise pose growing challenges to many aspects of life in the Northeast. Infrastructure, agriculture, fisheries and ecosystems will be increasingly compromised. Many states and cities are beginning to incorporate climate change into their planning.
Northwest. Changes in the timing of streamflow reduce water supplies for competing demands. Sea level rise, erosion, inundation, risks to infrastructure and increasing ocean acidity pose major threats. Increasing wildfire, insect outbreaks and tree diseases are causing widespread tree die-off.
Southeast. Sea level rise poses widespread and continuing threats to the region’s economy and environment. Extreme heat will affect health, energy, agriculture and more. Decreased water availability will have economic and environmental impacts.
Midwest. Extreme heat, heavy downpours and flooding will affect infrastructure, health, agriculture, forestry, transportation, air and water quality, and more. Climate change will also exacerbate a range of risks to the Great Lakes.
Southwest. Increased heat, drought and insect outbreaks, all linked to climate change, have increased wildfires. Declining water supplies, reduced agricultural yields, health impacts in cities due to heat, and flooding and erosion in coastal areas are additional concerns.
The US recently did not sign the Paris Treaty which works to eliminate or reduce emissions of burning fossil fuels and deforestation. I believe this was a huge mistake and my question for this week is as follows: is there a way to reverse global warming and climate change? If so, what can we do?
