Climate change is real and already affects humans.

Climate change is real and is increasingly becoming a part of our daily lives. New research and studies over the past six months have highlighted the latest facts about the man-made shift in our global weather systems and their impact on our planet.

First, there is no question that rising temperatures and increasingly chaotic weather are the work of humanity. There is a 99.9999% chance that people are the cause of global warming, a February study reports. That is, we have reached the "gold standard" for safety, a statistical measure typically used in particle physics.

The mechanism has been well known for decades. People burn fossil fuels such as oil, coal and gas, which release carbon dioxide (CO2), methane and other gases into the earth's atmosphere and the oceans. CO2 is the greenhouse gas most responsible for warming.

Benjamin Santer of the Lawrence Livermore National Laboratory in Livermore, California, California, lead author of the study, told Reuters, "The story of scientists not knowing the cause of climate change is wrong.

The Hottest Record

The past five years have been the five warmest since records began in the late 19th century.The Earth has experienced 42 years (since 1977) with, according to the National Oceanic and Atmospheric Administration an above-average global temperature.

Based on five separate datasets that record the Earth's climate, the global average temperature for the first 10 months of 2018 was about 1.8 degrees above what it was in the late 1800s. At that time, the industry began emitting large quantities of greenhouse gases into the atmosphere.

Australia had this in January Year record heat at record high. The city of Port Augusta reached the hottest day since the record began in 1962 with a temperature of 121 according to the Guardian .

The heat was so intense that bats from trees fell to the Australian Broadcasting Corporation.

Carbon dioxide rises by 46%

The increasing amount of carbon dioxide and other gases released from the burning of fossil fuels into the atmosphere through industry, transportation and energy production enhances the Earth's natural greenhouse effect.

Carbon dioxide is the most abundant greenhouse gas produced by human activities due to the burning of fossil fuels.

The carbon dioxide content of the air in March was 411.97 parts per million and continues to rise. It has now reached values ​​in the atmosphere that have not been seen for 3 million years.

This represents an increase of 46% over the industrial revolution in the 19th century, when the CO2 content was around 280 ppm. The level rose as people started burning large quantities of fossil fuels to run factories and heat homes and release CO2 and other greenhouse gases into the atmosphere.

Scientists say that to get a habitable planet, we need to lower the level to 350 parts per million.

Rising seas

A consequence of higher temperatures is the melting of the polar ice caps, which causes sea levels to rise. The oceans have risen by one centimeter in the last 50 years due to melting glaciers alone, a study published this month in the journal Nature .

The earth's glaciers are now losing up to 390 billion tons The study suggests that ice and snow could be produced each year.

Global warming has melted over three trillion tonnes of Antarctic ice over the past quarter century and tripled ice loss there in the last decade, another study released in June said.

Americans kill, billions cost

Extreme weather events, some of which were exacerbated by climate change, killed nearly 250 Americans and cost the nation at least 91 Billions of Dollars According to the National Oceanic and Atmospheric Administration 2018.

The unusual heat in the western US in 2018 contributed to a devastating forest fire that killed dozens of people. From a monetary point of view, Western countries have suffered their most expensive wildfire season so far: $ 24 billion in damage.

Hurricanes Michael, which caused $ 25 billion in damages, and Florence at $ 24 billion, were the other two major weather disasters in 2018.

New York City with the weather in Arkansas

] If the amount of carbon dioxide in the atmosphere is not lowered, the temperatures continue to rise. A study published in February showed how different the climate in US cities will be in 60 years if greenhouse gas emissions persist.

The study Nature found that the future climate on average corresponds to that experienced by an area 528 miles to the south today.

This means that New York City could have the Arkansas climate by 2080. Minneapolis could be more like Kansas and San Francisco than the foggy climate. Other cities in the south could experience a climate without a modern equivalent in North America.

"The children who live today, like my daughter, who is 12 years old, are experiencing a dramatic change in the climate. It's already underway, "said Matt Fitzpatrick, study author of the study at the University of Maryland's Center for Environmental Science.
