Why is the winter colder while the Earth heats up?

Earth's climate is becoming more and more severe. Some countries, such as the United States, recorded many days of record low temperatures than the record high temperature days, while in other countries, the temperature is increasing.

Calling the climate change process "global warming " is probably not an accurate way of calling. "Warm up" makes you feel that the weather will heat up at a slow, slow, steady pace - just like when heating a dish. But, that is not how the global climate system, which is very complex.

The increasing concentration of carbon dioxide and other heat-retaining gases is just one of many factors affecting the global climate. Other factors such as the temperature difference from year to year naturally existed before the global warming due to human influence. In a short time, the Earth's temperature could rise and fall like a company's stock on the stock exchange. But, the long-term climate trend will not change, and this is the most important thing for us.

The US National Climate Data Center (NCDC) has revealed that the US temperature in November is 5.3 degrees Celsius, 0.2 degrees Celsius lower than the average of the 20th century. This is It is very surprising, because both the United States and other countries around the world have been continuously influenced by global warming. In most other months, the average temperature in the US is higher than the average of the 20th century, which is considered a "standard" level for the normal climate.

Globally, for the past 29 years, there has not been a month with an average temperature lower than the 20th century average. However, in November in the US, the highest total temperature record of the day reached the lowest level in history, and the lowest temperature of the day reached its lowest level in history, more than three times the highest total record of the highest daily temperature, the lowest temperature. in the day reached the highest level in history.

Climate Central journalist Andrew Freedman explained:

"This is a complete reversal from last year - the warmest year in US history - the year when the highest number of record temperatures surpassed the lowest temperature record at a rate of 4/1. This is also is a reminder of the unusual natural change in the short term, in the context of global warming in the long run ".

Even the Arctic is less affected by climate change than other years. The National Oceanic and Atmospheric Administration NOAA has just released a report on the North Pole, one of the most warming places in the world. Summer in the Arctic this year is "cooler" than most recent years, and while summer ice (one of the factors that assess climate change for the North Pole) melts down to low levels. 6th since the late 1970s (when NOAA began monitoring the ice), this year's temperature is still much lower than 2012. "In 2013, the Arctic ended a series of years of warming. record and ice melted much, " David M. Kennedy, NOAA's deputy secretary of operations, announced at a conference in San Francisco.

So should we stop worrying about the global climate change process? The answer is no! Mr. Kennedy said that although this year is a "good" year for the Arctic if only considering the recent years, this is still a bad year considering the whole history."A rather cold year in some parts of the Arctic doesn't make much sense to counter the trend of the last 30 years: the Arctic is heating up very fast, becoming" greener "and witnessing many changes, causing images. influence people, physical environment, aquatic ecosystems and onshore " . The Arctic is "greener" (meaning that trees grow due to warmer climates) are a clear sign that the climate is warming, the Greenland ice continues to melt and snow falls in the Northern Hemisphere. May and June are below average. The average temperature in the Arctic has increased by about 2 degrees since the 1960s, twice as fast as other regions in the world. A year with a lower temperature will not change that trend.

This will also be true for the United States, although this year there are more record cold days than the number of record hot days. November in the United States may have been abnormally cold, but that is only compared to the recent particularly warm years (2012 is a record hot year for the US). While the United States has had an unusually cold year, the global average temperature is still above the average, and 2013 will still be one of the warmest years in history. If 2014 becomes an El Nino year, this is likely to be the hottest year in history, the climate change process will not be changed by just a few more cold days than expected.
