Essays about global warming and climate change

Even though all scientists adhere to scientific skepticism as an inherent part of the process, by mid November the word "skeptic" was being used specifically for the minority who publicised views contrary to the scientific consensus. This small group of scientists presented their views in public statements and the media, rather than to the scientific community. In academic literature and journalism, the terms climate change denial and climate change deniers have well established usage as descriptive terms without any pejorative intent.

Essays about global warming and climate change

Draft - 1. The observations of how our planet has changed are real. What they are telling us about our future is open for interpretation. The majority of climate scientists think they paint a picture of a rapidly warming at least in any geological or ecological sense world, where the rate of warming over the last few years has been accelerating.

As such it is impossible to make exact predictions how climate will change over the next few years or decades. However, we can consider how climate may continue to change in terms of risk.

This is discussed in the concluding Section 7. How should we react to the observed global warming? The observations show a growing risk to human society from runaway global warming, and they beg explanation. It is also the case that the Arctic as a whole appears to be warming at something like twice the rate of the rest of the planet.

This essay focuses on observations of what appears to be the start of runaway warming in the Arctic that may have profound effects on global climates over the next few years; and a plausible cause - the warming driven release of methane gas from permafrost forming a strong greenhouse cap over the Arctic Ocean.

German scientists have shown once again that climate change remains a global problem, with China’s climate impact, for instance, hurting . Introduction. What exactly is global warming and why is it worthy of consideration? Global warming is the scientific phenomenon linking an increase of the average earth temperature because of a trapping of radiation within the earth like a greenhouse.

Evidence shows that over the last few years winter cooling over the Arctic Ocean has been significantly retarded when the sun is below the horizon for months at a time when heat absorbed over summers with 24 hour daylight should be radiating away to outer space.

The observations summarized here are based on computerized analyses of many millions of data points collected per day covering the entirety of the satellite era, beginning in To encapsulate summaries with the minimum of text and numeric data, I have used a number of animated maps where primary data is encoded in color.

Changes in this data over time intervals ranging from days to months and years are shown as a stack of gif images forming short movies.

To me, in addition to a continuing rise in arctic temperatures, the most conspicuous indication that we may have passed a tipping point where arctic warming is increasing at an ever faster rate as shown by the graph below. This depicts changes in the areas extents covered by sea ice on the whole planet.

Over the half year on each day of the year the area of the globe covered by sea ice has been by far the lowest it has ever been in the satellite era for those days and from 7 January until around March - a period of two whole months - there has been less sea ice on the planet since the previous record low recorded in mid February Such a major deviation from "normal" indicates there are currently some serious climate changes taking place in the world.

Accompanying the concerns of climate change and global warming is the media spin, propaganda, and special interests. For many years in some countries, scientists and environmental groups raising concerns about climate change faced stern opposition, and at one time, ridicule.
