The opening scene shows the collapse of a massive ice shelf (a floating glacier) in Antarctica. Could this really happen? If so, how might it affect global sea levels? The collapse of massive ice shelves have become more common with the changes in climate.
“66.4% of the studies had no stated position on anthropogenic global warming, and while 32.6% of the studies implied or stated that humans are contributing to climate change, only 65 papers (0.5%) explicitly stated "that humans are the primary cause of recent global warming.” (“Popular Technology, "1350+ Peer-Reviewed Papers Supporting Skeptic Arguments against ACC/AGW Alarmism,” populartechnology.net, Feb. 12, 2014.) 32.6% of humans are only contributing to the global air, but natural resources such as lightning strikes which cause wildfires can affect the global air, and etc. This means human activities are not really causing that much of an effect to global warming, but the world 's natural resources
Indeed, Inhofe explains that the increase number of boats blocked by ice in the arctic is a sign of climate change. This is the symbol of Inhofe's scientific rigor. Some examples of known blocked boats would show that the number of blocked boat increases (but we have no figures) which would show that the ice does not decrease but increases and therefore the global warming is false. You do not have to be a genius to see that this reasoning is ridiculous. In addition, a simple satellite image proves the opposite, that is to say that the ice floes back.
For example, not only are there high risks of potential meltdowns, but the nuclear waste that is is created is extremely toxic. Also, the energy source of nuclear energy is Uranium, which is a scarce resource, and its supply is estimated to last only for the next 30 to 60 years. Why are people choosing to build numerous nuclear power plants all over the world when we will eventually get stuck with them and their radioactive waste in a short period of time? The film The China Syndrome is fair to the nuclear industry because it explains the potenial dangers of a nuclear power plant realistically to the
An article from the Pre Research Center states that “ 74% say there is solid evidence that the average temperature on Earth has been getting warmer, while 23% say there is no solid evidence that the Earth has been warming” ( “Global Warming and Environmental regulation, personal environmentalism”) This shows that over the years more people in the world believe that there is such thing of climate change and agree that the temperature of the atmosphere has increased dramatically. Many people think they can’t help fix this problem, though they are wrong. Big organizations aren’t the only ones who can help. An individual can take actions to stop climate change, these actions can conclude to “ to help stop climate change, such as driving less, hanging washing on the line instead of using the dryer, using less water, or turning the heating down.”( Heres How You Can Help Stop Climate Change) This shows that not only a group of people, or people with a lot of money can help stop climate change. Individuals can stop climate change by doing a simple
There is evidence that suggests that along with rising carbon dioxide levels, volcanic dust may have been a large contributing factor in the deglaciation of Snowball Earth. Evidence supporting ice covered continents and oceans has been provided by deposits such as iron-manganese in glacial sediments. This indicates that the ocean was lacking oxygen and that there were probably glacial formations (Hoffman & Li, 2009). Simulations have shown that for atmospheric carbon dioxide to have been fully responsible for the termination of snowball Earth, the levels would have to have been about 550 times the present levels (Pierrehumbert, 2004). It is highly unlikely that the level of carbon
The article, Climate change and forest fires synergistically drive widespread melt events of the Greenland Ice Sheet, spoke about the different effects on the ice when the climate changed or there was a forest fire. The article, Concentrations and mass size distributions of particulate trace elements at summit, Greenland: Impact of boreal forest fires, included facts on the different chemical elements “affected by emissions from boreal forest fires” (Maenhaut, Hillamo, Mäkelä, Jaffrezo, Bergin and Davidson,1997, pg. S565) The article, High northern latitude forest fires and vegetation emissions over the last millennium inferred from the chemistry of a central Greenland ice
Ice reflects 85 percent of sunlight and open water reflects just seven per cent”(Evans et al.). This is a big deal because no sunlight that is not reflected is absorbed and that adds to the problem of global warming even more. If this were to continue to happen until the point that there are no ice caps, the continents would have a new geographic outline because parts of it would be undersea level. Basic comprehension of how the drilling in the Arctic is connected to global warming helps people understand how important passing a law that bans oil drilling in the
They instead claim that only certain societies, consisting of only a small percentage of humans, has caused the most damage. Malm and Hornborg point out that the “advanced capitalist countries… composed 18.8% of the world population, but were responsible for 72.7% of the Co2 emitted since 1850” (Malm and Hornborg, 3) while “45% of the human population accounted for 7% of emissions” (3). They use this evidence to drive their point that the fossil fuel economy resulting from industrialization and causing the most drastic effects of the Anthropocene “was not created nor is it upheld by humankind in general” (1). They instead argue that there is a societal side to the Anthropocene where certain human societies and their ideologies further the damage done to the environment. The geology of mankind?
