Exam 25: Union of Concerned Scientists, Smoke, Mirrors Hot Air: How Exxonmobil Uses Big Tobaccos Tactics to Manufacture Uncertainty on Climate Science
Which of the following corporations is the most profitable in history?
D
Which of the following industries formed the Global Climate Coalition in 1989 to aggressively respond to emerging scientific studies about global warming and oppose governmental action designed to address the problem?
A
Compare and contrast the evidence to support and refute the claim that human activity is causing global warming. Which argument is more convincing in your opinion? Why?
The evidence to support the claim that human activity is causing global warming includes the increase in greenhouse gas emissions, particularly carbon dioxide, from industrial processes, deforestation, and the burning of fossil fuels. Additionally, there is a correlation between the rise in global temperatures and the increase in human activities that release greenhouse gases into the atmosphere. Furthermore, scientific studies have shown that the isotopic signature of carbon dioxide in the atmosphere matches that of fossil fuels, providing further evidence of human influence on climate change.
On the other hand, the evidence to refute the claim that human activity is causing global warming often focuses on natural climate variability and external factors such as solar radiation and volcanic activity. Some argue that the Earth's climate has gone through natural cycles of warming and cooling throughout its history, and that the current warming trend may be part of a natural cycle rather than solely caused by human activity.
In my opinion, the evidence supporting the claim that human activity is causing global warming is more convincing. The overwhelming consensus among climate scientists and the abundance of empirical data linking human activities to the increase in greenhouse gas concentrations and global temperatures make a compelling case. While natural climate variability and external factors may play a role in shaping the Earth's climate, the evidence for human-induced global warming is robust and supported by a vast body of research. Therefore, I find the argument in favor of human-induced global warming to be more convincing.
The recent era of global warming was declared to have commenced in:
The fundamental principle that heat-trapping emissions influence the Earth's temperature was first discovered in 1896.
Describe how ExxonMobil has manufactured uncertainty about the scientific consensus on global warming. In what ways is this campaign similar to efforts by the tobacco industry to prevent government regulation?
Gelbspan proposed that new energy systems, which would replace the consumption of fossil fuels, could be developed in as little as:
There has been a nearly 40 percent increase in the concentration of carbon dioxide in the atmosphere since the beginning of the industrial era.
If it were a country, ExxonMobil would rank sixth in the world in emissions from end use combustion of its products.
ExxonMobil has drawn across a broad spectrum of scientists representing multiple disciplines to challenge the claim that global warming is a naturally occurring process.
Scientists now agree that the unprecedented rate of global warming is caused primarily by human activity.
Which of the following companies have begun to invest in clean energy technologies and publicly committed to reduce their heat-trapping emissions?
