Global warming thesis statement

Homework for me

A more recent peer-reviewed paper examined existing studies on consensus in climate research, and concluded that the 97 percent estimate is robust. This level of consensus is equivalent to the level of agreement among scientists that smoking causes cancer — a statement that very few people, if any, contest today. The American public also increasingly agrees that global warming is happening. A poll from Yale found that 70 percent of Americans believe global warming is happening, while record low number of Americans 12 percent say the opposite. The acceptance of human-caused emissions as the cause of warming is not keeping pace with those that believe it is happening, but it is at 53 percent.

There is no shortage of published research on the consensus of climate scientists and climate science when it comes to human-caused global warming.

How to Write a Good Thesis Statement

In addition to the references above, you can read about how the discussion on consensus developed over time in these studies. Many different scientific societies in the United States and numerous national academies of science from around the world have also issued statements that verify the scientific claims about human-caused warming see below. Therefore, when it comes to scientific consensus on global warming, it is important to clarify what type of uncertainty exists, and what type does not: there is strong certainty on the types of impacts that global warming is causing or would be likely to cause under a given scenario for emissions , but less certainty on the exact timing and intensity of these impacts.

For instance, on the issue of sea level rise, we know with certainty that it will happen — it is already happening — and projections under different scenarios give us a range of possible rise. But if we significantly reduce emissions, the rise will be closer to the lower levels of projections. The same is true for how much warming will actually happen, or how much land-based ice and glaciers will melt.

All these things are already happening, but future rates are not known because they, too, depend on the rate of future emissions. This information is critical to making smart collective choices and for planning for the future.

Uncertainties are not a reason to delay action on climate change. Quite the contrary: those uncertainties are really a consequence of our collective choices, and a risk we must prepare for. Being prepared for these scenarios is simply smart planning. Nobody wants to be caught unaware and unprepared.

Thesis statement about climate change and natural calamities

Many scientific societies and academies have released statements and studies that highlight the overwhelming consensus on climate change science. Some global warming topics have produced extensive research worldwide and can serve as topical guides in formulating your thesis statement. The causes of global warming are complex, including natural and man-made emissions of carbon dioxide and methane.

Climate Change

Use your thesis to highlight the difference between natural sources and man-made sources. For example, according to the Environmental Protection Agency, carbon dioxide concentrations in the atmosphere have risen from parts per million in the 18th century to parts per million in Human activities release more than 30 billion tons of carbon dioxide each year, or times as much as volcanoes. Focus your thesis on this discrepancy, how man-made carbon dioxide sources, such as fossil fuel consumption, have eclipsed natural sources of the gas. Your thesis statement may focus on the relationship between rising surface temperatures and declining sea ice, specifically ice in the Arctic.

The evidence is overwhelming. Record-breaking temperatures, humidity, and sea level rise, along with many other indicators, show that the Earth is warming fast, and that all the heat-trapping emissions we release into the atmosphere from burning fossil fuels is changing our climate. The time to act is now. But, many powerful industry interests have hindered action and have, largely through surrogates , spread dangerous myths about climate change.

One of the preferred tactics these groups use to sow confusion is to promote studies that either ignore or misrepresent the evidence of thousands of articles published in well-established and well-respected scientific journals, which show that global warming is happening and that it is caused by humans.

Scientists worldwide agree that global warming is happening, and that human activity causes it. Human influence on the climate system is clear, and recent anthropogenic emissions of green-house gases are the highest in history.

Description:

The scientific consensus is clear. Building on two previous studies , a landmark peer-reviewed study evaluated 10, scientists to confirm that over 97 percent climate scientists agree, and over 97 percent of scientific articles find that global warming is real and largely caused by humans.
