Man made: made or caused by human beings.
Fossil Fuels: a natural fuel such as coal or gas.
What are the ideas behind man made climate change/ global warming?
Some ideas behind man made global warming is that many scientist believe that climate changes main source of occurring is from greenhouse gases, which humans play a role in producing. Former NASA scientist Roy Spencer who has a Ph. D in the study of climate change explains, “The basics of why so many scientists think global warming is man made. Earth’s atmosphere contains natural greenhouse gases (mostly water vapor, carbon dioxide, and methane) which act to keep the lower layers of the atmosphere warmer than they otherwise would be without those gases. As of 2008, the concentration of carbon dioxide in the atmosphere was about 40% to 45% higher than it was before the start of the industrial revolution in the 1800’s” (Spencer).Us humans play a large role in the amount of greenhouse gasses that are being given off, we play a large role because of the amount of fossil fuels that we use in our daily lives. The Industrial revolution was a huge turning point because instead of manufacturing things in homes we shifted to powered, special-purpose machinery, factories and mass production.
Climate change: The environmental and temperature changes that are affecting the earth.
Emission: the production and discharge of something, especially gas or radiation.
Are we finding ways to deal with climate change? Since climate change has many different points of view about if climate change is really happening, or is it getting warmer or colder. But most scientists agree that greenhouse gases play a role in the change of climate, The Norwegian University of Science and Technology (NTNU) explains that “For example, the production of steel, other metals, cement and chemicals (including plastic) account for roughly 50 per cent of all industrial greenhouse gas emissions.But recycling of scrap metals, once done to reduce costs, also reduces greenhouse gas emissions” (The Norwegian University of Science and Technology). The scientists from Norwegian University explain that if we can control our production of metals and different chemicals. Also if we can find a way to safely recycle these metals and chemicals, we could start to see some positive changes when it comes to the environment. From the David Suzuki Foundation (Solution is in our Nature) the members of the foundation cover the fact that we all play a role in climate change. Also that we all have our own tiny carbon footprint that does have a part in dealing with climate change. The David Suzuki Foundation states that “the choices we make in our day-to-day life — how we get around, what we eat, how we live — play a major role in slowing climate change” (David Suzuki Foundation). They are saying that our day to day life plays a role in climate change and the only way we would be able to slow down climate change is if everybody was on board. To get everyone on board there would have to be clear factual evidence instead of all these maybes and ideas that are being talked about in each article.
Are the recorded temperatures on a graph accurate to the idea that “each year gets warmer and warmer”? Three years in a row the heat records have been broken all over the globe, scientist are keeping a close eye on this trend because no one knows if it will keep occurring or if it is just three year trend that will turn out to be a myth? From the NOAA (National Oceanic And Atmospheric Administration) they go on to make a table that shows the heat records...
These were the records shown, you can see that it goes from 2015 as being in first to 2014, to 2010, to 2013, to 2005. So these number do not necessarily go in order, that shows that we need more data to figure out if this is just a unique trend, or if it is a real problem that is taking place. From the temperature and perception maps time series they explain that “ Much of the record warmth for the globe can be attributed to record warmth in the global oceans. The annually-averaged temperature for ocean surfaces around the world was 0.74°C (1.33°F) higher than the 20th century average, easily breaking the previous record of 2014” (Temperature and perception maps time series). A Lot of the change being noticed is happening on the oceans because the temperature change is so obvious and clear that scientist can get a pretty good idea on how much the temperature is changing. Overall we need to keep studying this broad topic of climate change and see if the earth keeps changing this drastically.
The NOAA (National Oceanic and Atmospheric Administration) choose to make its evidence clear by creating different data tables with the different annual temperatures for each year. They also listed all facts they didn't include very much opinions, they just stuck to what has been proven.
