July is on track to become the hottest month in recorded history, climate scientists say, after the hot waves of North America and the Arctic have seen warmer warmer temperatures. The last sign that the overall climate of the planet is warming, and that human activities cause extreme events such as heat waves, is more likely and more intense for scientists to say.
Even more than a week left until the end of the month, dozens of experts are already anticipating that the current record of July 2017 will fall.
"It appears to be a strong possibility that we will end the hottest month-long," Bryan Breettneider, a climate researcher at the University of Alaska's Fairbanks, said. (In this case, "ever" means since modern recording was started in 1880.)
In July 2017, when the previous record was set, the average global temperatures were 2.16 degrees Fahrenheit higher than the average 20th century before July 57.8 degrees Fahrenheit, according to the National Oceanic and Atmospheric Administration, which collects climate data and temperature records. July is expected to barely surpass the average temperatures of two years ago, say scientists who study climate patterns.
"Of course we won't know until all the talents are in, but we have a good time now to beat the record," said Jack Williams, director of the Center for Viscosal Madison's Climatic Research Center. .
"July is the hottest month of the year globally. If this July turns out to be the warmest July (it has a good shot), it will be the hottest month we've measured on Earth!" Michael Mann, a climate scientist Pennsylvania State University, tweeted July 15.
In an email to NBC News MACH on Monday, Man called the new record "likely," saying there is now a "greater than 50/50" possibility that the month might set a new high temperature.
July's anticipated milestone comes on the heels of another variation of climate record: last month, the hottest was in June. Average global temperatures last month were 1.71 degrees Fahrenheit higher than the 20th century average for June 59.9 degrees Fahrenheit, according to NASA and NOAA, which independently track global surface temperatures.
This summer was a scurvy for much of the world, with Europe suffering from a deep heat wave in late June that the higher temperature was recorded in France. This past weekend, about 169 million people across the United States were under heat alerts as cities in cities like New York City; Little Rock, Arkansas; And memphis, Tennessee, climbed into the triple digits. And the week, another heat wave is expected to hit parts of Western Europe.
While steamy temperatures are expected in June and July in Northern Hemisphere, Williams said the summer record heat is far from normal.
"The climate system is like a dough for steroids," Williams said with a baseball analogy. "Heat waves from today will be the normal morning events."
Man said the latest warming trends show the impact of climate change on the planet.
My husband said, "This is part of an anxious pattern of streaking broken records that we've found out that it won't happen in the absence of climate change." It's just another confirmation, along with the rush of unprecedented extreme Weather events we've seen in recent years, from the fact that the impact of climate change is no longer subtle. They look at us in the face. ”
Human Activities – Primarily from burning fossil fuels – emitting carbon dioxide and other greenhouse gases that traps heat in the atmosphere. Increasing greenhouse gas emissions are associated with warmer global surface temperatures; According to the climate central, the planet's 10 hottest years were recorded in the last two decades.
Breton schneider said, "It is internal fluctuations in the climate system, which brings the metropolitan metaphor around from year to year, but the trend is impossible.
Unless significant measures are taken to curb greenhouse gas emissions, scientists expect temperature records to stop falling. Scientists say global temperatures could increase in the century by at least 3.6 degrees Fahrenheit – creating conditions on Earth that have not been seen for more than 2 million years.
“The closest equivalents are found in the plyosene [Epoch]When sea levels were higher than ten feet and there was a much warmer world, "Williams said. This was a time before human evolution. Part of the bigger picture is that we push the climate system to what we haven't seen in our societal experience – and even in our experience of our species. "
The current hottest recorded year was 2016, when a commonly recurring climate pattern, known as El Niño, contributed to some of warmer-than-usual conditions. According to the NOAA, this year, until January this year, the number of people in January to June has risen as the second-highest record year on record.
For Williams, the record temperatures are urgently needed to try and sound the alarm for climate change.
"It's tough to be a climate scientist and see the trends we're going for and trying to raise awareness," Williams said. “It feels like an uphill battle. At the same time, I felt that this was the defining problem of my generation, and there was a fight and conversation worthy of it. This is important work, so we only keep it. ”
