2010 will be the hottest year in history?

The global warming combined with the ocean warming up due to the El Nino weather phenomenon, 2010 is considered one of the hottest years in history.

According to the analysis released on July 15, 2010 by the US National Oceanic and Atmospheric Administration (NOAA), the recorded temperature of the surface and ocean in the period from January to May The last 6 are at the highest level compared to the temperatures recorded since 1880.

The average temperature in the first half of 2010 was 57.5 degrees Fahrenheit, equivalent to 14.2 degrees C. This temperature increased by about 1.2 degrees F (corresponding to 0.7 degrees C) compared to the heat level the average of the twentieth century.

Jeff Masters, weather Underground's director of meteorology, said: 9 countries have been recorded to have very high temperatures and are in warning about the hottest regions in the world, including Pakistan. On May 26, the temperature measured in this country was 128.3 degrees F, equivalent to 53.5 degrees Celsius. This is the highest temperature in Asia.

While some areas heat up rapidly with rapid increases in heat such as Asia, Peru and the eastern United States, other extreme weather events make some other areas unusually cold. Guizhou Province, China is an example of low heat recorded in June.

One of the important reasons that in 2010 could become the hottest year in history was attributed to the interaction of two extreme climatic phenomena: El Nino and La Nina.

Normally, every 3 - 7 years, El Nino and La Nina will "swerve" for each other. They happen alternately and help the temperature of the Central - Eastern Pacific region stabilize. At around May, the El Nino phenomenon will dissipate, paving the way for La Nina to appear. However, this year, the El Nino phenomenon tends to last through August and that can break the balance, the temperature can hardly be 'cooled' back.

Basically, the global warming phenomenon can be compared to a two-headed escalator and the unusual El Nino climate phenomenon, La Nina as two people standing at both ends of the ladder, going up and down. down depending on the movement of the other phenomenon. El Nino, La Nina are constantly moving and when they are no longer at the top of the ladder, the balance has been broken.

Kevin Trenberth, senior scientist at the National Center for Atmospheric Research in Boulder, Colorado, said: 'It's not just a global warming phenomenon and it's not a transformation of nature. of nature alone. It is a combination of both '.

However, Trenberth also noted that the melting of the Arctic and rising sea levels are not the consequences of the short-term impact of the El Nino or La Nina climate phenomenon.

Since 1992, satellites have shown that the sea level has risen by about 2.2 inches (5.6 cm) corresponding to an increase of 0.3 m or more in a century.

NOAA's new report also indicated that, in June 2010, the Arctic ice covered area reached about 4.2 million square miles, equivalent to 10.9 million square kilometers. This coverage is 10.6% lower than the level of coverage from 1979-2000. This is the lowest level of coverage recorded from 1979 to now.

Trenberth emphasized: Ice melting fast and rising sea levels are the clearest evidence for the rapid warming of the Earth.

Mr. Derek Arndt, US National Climate Data Center said: It is too early to confirm that 2010 will be the hottest year in history - the identity is currently being held by '2005' but certainly at a low level. Mostly, 2010 will also be ranked 3rd or 4th in terms of recorded heat.
