Today, climate change is worse than anything the Earth has experienced in the past 2,000 years

The global climate is changing faster now than at any other time in the past 2,000 years.

This is the conclusion of the three articles was published on July 24, in the journals Nature and Nature Geoscience that examined the climate over the past thousands of years. The researchers showed that the use of any of the previous variations, that is, not the Little ice age and the warm period known as the Medieval Climate Anomaly, or any of the other famous shift was the global reach of modern climate change. The past variations tend to be localised, affecting mainly the region at the time. Modern, climate-change, on the other hand, it is messing up the rest of the world.

“As the temperatures rise and fall throughout steps [in the past],” the editors wrote in an accompanying op-ed piece in Nature Geoscience. In particular, the early, cool and warm intervals that lasted for centuries and peaked at different times in different regions.

This is a radical departure from the modern, climate-change, Scott of california. George, a climate scientist at the University of Minnesota, who was not involved in the study, wrote in a news and views article in Nature. [10 Climate Myths Busted]

“Even though the Little ice age was the coldest period of the last millennium, and the timing of the lowest temperatures will vary from place to place,” Approx. George wrote. Two-fifths of the planet have been subjected to the cold conditions during the mid-nineteenth century, but in the depths of chill occurred several centuries earlier in other regions as well. Even at the peak of the Medieval Climate Anomaly, and only 40% of the Earth’s surface to reach peak temperature, at the same time. The use of the same data, the warming of the earth is today, it is second to none: over 98% of the planet’s surface, the warmest period of the modern Era took place in the late twenty-first century.”

This means that almost every part of the planet’s hottest year in the last 2,000 years and, at the same time.

And in the 21st century, which is beyond the scope of the present articles, it is a lot hotter than the 20th century to the present. In fact, it is the world on track to keep global warming as greenhouse gases continue to accumulate in the atmosphere.

For the development of a rigorous picture of the global temperature over the past 2,000 years, the researchers used it on about 700 of the records of the so-called the PAGES 2k proxy temperature database. This database completes the proof of the ice cores, trees, coral, and other materials, which change their appearance, or chemical composition, on the basis of the global temperature. The researchers used the records to build a detailed map of the climate variability in the entire world. And none of them seem to be a consistent, ongoing shifts that we see today.

Of course, the underlying causes are different, too. The proof of the previous 2000 years shows that the short-term volcanic events were the main causes of the climate fluctuations, the authors wrote. The human activities that may have been a small secondary factor over that period of time. Right now, the people are the ones who are driving the bus. And this time, the head in the direction of the edge of a cliff.
