It’s Not Your Imagination. Summers Are Getting Hotter.

In the 1950s, an unprecedented very hot summer became commonplace.

This year's hot summer event, such as heat waves flowing through Southern Europe, is part of this broader trend, Pakistan's temperature is close to 130 degrees Fahrenheit.

According to data from retired climate scientists at NASA and Professor James Hansen at Columbia University, the graph above shows that summer temperatures have changed to extreme temperatures in the past few decades.

To create a bell curve, Dr. Hansen and two colleagues compared the actual summer temperatures in the 10 years since the 1980s with the baseline average. During the reference period from 1951 to 1980, one third of the summer temperatures in the Northern Hemisphere were within the range of "almost average" or normal range. One third is considered cold and one third is hot

Since then, the summer temperature has risen sharply. Between 2005 and 2015, two-thirds of the value belonged to a popular category, and nearly 15% belonged to a new category.

In fact, this means that most summers are hot or hot compared to the mid-20th century.

Todd Sanford, Research Director of Climate Central, a nonprofit organization of science and news, said the rapid rise in summer temperatures in scientific extremes is what scientists expect from climate warming "It will match correctly."

In each of the above periods, the summer temperature distribution forms a so-called bell curve. This is because most measured values ​​are close to the average and a bulge (bell) is formed in the center. Less frequently more extreme temperatures fall on the wing, there is a heat wave on the right side and cold heat on the left side.

As the average value of the curve (the peak vertex) moves to the right as time goes on, more temperature will eventually appear in more extreme high and high temperature categories in more places, but cold is lower temperature It will appear in category End

Dr. Hansen's curve tends to be flat, and some people think that this shows a bigger temperature change. However, other climate scientists, including the energy system analyst at the University of California, Berkeley, Keke Hausfather pointed out that this impact mainly reflects global warming earlier in other parts of the world than in other regions It is. After considering global warming, there is no evidence that the temperature in most parts of the world will change more easily.

Dr. Hansen's data says, "Although it may not look big, it has a big influence on extreme events, but it really emphasizes the change in the average, which is an element that affects society and the ecosystem "Said Dr. Sanford. The findings clarify what happened so far and will provide "a glimpse of our future".

Summer - This year the world is getting hotter. Especially in Southern California, it is natural that the temperature rises several times every year. All of these increases in temperature are due to climate change and the lack of all our gas and atmospheric gases. Soon our temperature will be very hot, we will do nothing in the world, and those high temperatures will make us arrive faster.

The temperature in the Middle East is starting to rise. As the desert approaches, the weather is getting hot. In addition to the increase in mercury, NEM has also gained popularity in this area and is becoming a topic in the block chain community. At the recent future Block Chain Summit, the NEM Team fired. Members of the EMU block chain industry and NEM supporters NEM Board members and Dr. Stephen Chia and Dr. Marwan Al Zarouni, Southeast Asia regional director are included in the panel discussion on the future of the 2,000-seat intelligent block chain It is. The city of halls All these are things that facilitate development and share advanced customizations offered by NEM block chains when building solutions.
