Earth Day is celebrated on two different dates in a year. The celebrations are carried out with great enthusiasm worldwide on both dates. The Earth Day was first time celebrated on April 22, 1970. Senator Gaylord started the celebration of Earth Day and he raised the awareness among people to take the responsibility of earth and life on earth. On 20th March, 1978, McConnell started celebrations of Earth Day nearly with the time of vernal equinox. Earth Day is celebrated with great keenness and unanimous passion simultaneously in all parts of the world on the same day. People having different backgrounds, beliefs, nationals, and religions add their part in the universal celebrations of Earth day.
Every year, according to a careful estimate, there are approximately more than one and half billion individuals who take part in various Earth Day campaigns. When this movement of saving life on earth started in 1970 on April 22, nearly 20 million Americans took part in this movement to achieve the goal of a hygienic and sustainable environment.

There are multiple effects of global warming, some which we do see today, and some that will appear more with the passage of time. Earlier in a post, I explained the various factors that lead to global warming, and its causes. Today, I will be discussing the consequences of global warming and its effects.
Global warming has led to the recent changes in the earth’s temperature and the sea levels. Although there is strong evidence that suggests that our planet is warming, but it is very difficult to identify a single cause of this.
As the Earth’s average annual temperature rises, we may see its various effects in different areas. One of its main consequences could be the rising sea levels. It could lead to many towns and cities that lie below sea level to become victim to flooding leading to loss of life and serious economical impacts.

BERKELEY — Not only has the average global temperature increased in the past 50 years, but the hottest day of the year has shifted nearly two days earlier, according to a new study by scientists from the University of California, Berkeley, and Harvard University.
Just as human-generated greenhouse gases appear to the be the cause of global warming, human activity may also be the cause of the shift in the cycle of seasons, according to Alexander R. Stine, a graduate student in UC Berkeley’s Department of Earth and Planetary Science and first author of the report.
"We see 100 years where there is a very natural pattern of variability, and then we see a large departure from that pattern at the same time as global mean temperatures start increasing, which makes us suspect that there’s a human role here," he said.
Although the cause of this seasonal shift – which has occurred over land, but not the ocean – is unclear, the researchers say the shift appears to be related, in part, to a particular pattern of winds that also has been changing over the same time period. This pattern of atmospheric circulation, known as the Northern Annular Mode, is the most important wind pattern for controlling why one winter in the Northern Hemisphere is different from another. The researchers found that the mode also is important in controlling the arrival of the seasons each year.
Whatever the cause, Stine said, current Intergovernmental Panel on Climate Change (IPCC) models do not predict this phase shift in the annual temperature cycle.
Details are published in the Jan. 22 issue of the journal Nature.
Temperatures at any given time of the year can be very different on land than over the ocean, Stine said, and a change in the strength and direction of the winds can move a lot of heat from the ocean onto land, which may affect the timing of the seasons. However, this seems to be only a partial explanation, he said, because the relationship between this pattern of circulation and the shift in the timing of the seasons is not strong enough to explain the magnitude of the seasonal shift.
The researchers also found that the difference between summer and winter land temperatures has decreased over the same 50-year period, with winter temperatures warming more than those in summer. They found that in non-tropical regions, winter temperatures over land warmed by 1.8 degrees Celsius and summer temperatures increased by 1 degree. Ocean warming has been somewhat less.
Stine noted that the study limited its focus to non-tropical regions because the seasons are more pronounced outside the tropics.
