Global Warming Trends

Benefits of is presenting this series of pages on global warming becaue we believe there is evidence to support it is real. Even so, we are open to be proven wrong, which is why there are pages on why it is not real. Fair is fair.

The truth is we just want people to be aware that human activities (as well as natural causes) have the possibility of creating adverse effects in the US, Antarctica, Greenland, and throughout the world.

Global warming can also be detrimental to wildlife such as polar bears, creatures like sea turtles, and sea life like coral reefs,not to mention human health, due to the spread of disease.

So is global warming a myth or are there facts to support it as a reality of our times? Is there really such a thing as the greenhouse effect? And if so, what is that?

Whether you believe global warming is real or not, we invite you to read what we have uncovered on the many pages of this site… and beyond. Remember, knowledge is power.

Global Warming Trends / Scientific Measures

When the accurate instrumental methods of temperature measurement were developed, scientists started to observe and keep records of the temperature in the lower spheres of the Earth’s atmosphere to see whether it changes with time or not.

Thanks to these scientific measurements and records, the scientists discovered a trend or tendency of average global temperature to increase which supports claims that global warming is real.

It is a scientific fact that the process of global warming is a very old process, which started thousands of years ago, however, either it is because of absence of accurate thermometers or because of some other factors, but scientists started to alarm on rapid progression of the global warming only at the end of the 20th century, when they saw that the mean global temperature raised for 0.74 ± 0.18 °C (1.33 ± 0.32 °F) during the 20th century.

This significant change in a relatively short amount of time lead some scientists to bring this information into the mainstream so that measures would be taken to finds ways to prevent global warming from spiraling – causing severe hurricanes and other natural diasaters, melting glaciers in Greenland and Antarctica, spreading disease, and destroying ecological systems and wildlife.

Global Warming Trends / Sea Level Rise

Over the past 20th century the sea level increased approximately 1.8mm per year. However, in the recent years scientists noted the increase in the annual sea level: between 1993 and 2003 the sea level added about 2.8 -3.1 mm annually. Scientists claim human activity and extensive fossil fuels use to be the main culprit of the progressive development of global warming in the recent years, which in its turn causes rising of the sea level.

The direct contributors or factors, which make the sea level to increase, are thermal water extension and adding water from melting ice glaciers. Actually, scientists say that currently it is mainly because of water extension that sea level rises, and ice melting is not that significant these days.

Water extension is a physical process when the volume of liquids, such as water, increases when their temperature rises. Ice melting adds new water to oceans thus rising its level. Though this factor is not the primary one, it is very unpredictable and scientists cannot tell for sure how ice melting can influence sea level in the nearest future.
Global Warming Trends / Methane Release

Methane is considered to be one of the greenhouse gases along with water vapors and carbon dioxide. When methane concentration increases in the atmosphere – it increases greenhouse effect and causes the so-called positive feedback effect, which again warms up the atmosphere.

Large quantities of methane are located in the Arctic regions in the natural gas deposits, permafrost and clathrates. Because of global warming, permafrost may degrade with time, thus releasing methane into the atmosphere. This will create another factor for further progression of global warming process and climate changes.
Global Warming Trends / Local Climate Changes

People, living in the northern hemisphere (North America, Canada, Northern Europe), have already felt climate changes in their areas: the winters became milder with less snow and higher temperatures. The current increase in the temperature has already caused certain changes in the ecosystem.

Besides, extreme weather conditions and phenomena, such as hurricanes, started to appear in the areas, where they have never been noticed before.

Global Warming Trends / Conclusion

So, while scientists still argue on whether the current global warming is man-made or not, it is already a fact that climate changes do happen this days. These changes may result in the significant consequences for all the Earth’s inhabitants.

That is why a wide range of means to slow down global warming are developed and implemented worldwide. The examples of such means are alternative fuel use instead of oil, gas and coal, prevention of further deforestation and decrease of greenhouse gases emissions into the atmosphere.
