The NOAA said these past 3 months the world has experienced its warmest climate in history. From December 2014 to February 2015, the recorded average global temperature was 55.22 degrees F, 1.42 degrees F higher than the climate average of the 20th century, which was 53.8.

Forget the unusually chilly temperatures in many parts of the north of the eastern part US and the eastern Canada, as the recent temperatures there don't represent the global climate in general. When you live in New York for example, you won't feel the global warming impact this past winter.

However, when we talk about the global temperatures, we certainly need refer to a trusted source like a report by National Oceanic and Atmospheric Administration (NOAA), an American weather agency with its headquarter in Washington D.C.. It said last Wednesday that these past 3 months on average has been the world's warmest climate ever recorded.

In huge contrast with the colder temperatures in the most north eastern area of the American continent, NOAA reported that the western US and most part of the world have experienced the warmest winter ever known in history. In the US, the record warmth was recorded to have taken place in California, Arizona, Utah, Nevada and Washington states.

 "The majority of the world's land surfaces, however, were warmer than average," reported NOAA, "with much-warmer-than average temperatures widespread across Central America, northern and central South America, Australia, most of Africa, and much of Eurasia, including a broad swath that covered most of Russia."

In addition to that, people living in the southern hemisphere were experiencing hotter-than-average summer. NOAA said it was the fourth warmest summer in the southern part of the equator.

We may guess what might be the major cause of this phenomenon. It can be the global warming effect. However, this time there is another speculated reason for the winter warmth. It is due to the El Niño effect, the warming of the water surface of the Pacific Ocean that affects the world temperature.
