Climate change is real and it already affects people.

Climate change is real and increasingly part of our daily life. New research and studies in just the last six months highlight the latest facts about the human-caused shift to our global weather and its effects on our planet.
Only among them is there no longer any question that rising temperatures and increasingly chaotic weather is the work of mankind. There is a 99.9999% chance that people are the cause of global warming, reported a February study. This means that we have reached the “gold standard” for safety, a statistical measure that is usually used in particle physics.
The mechanism is well understood and has been for decades. People burn fossil fuels such as oil, coal and gas, which emit carbon dioxide (CO2), methane and other gases in the Earth’s atmosphere and oceans. Carbon dioxide is the greenhouse gas that is most responsible for heating.
Studied author Benjamin Santer of Lawrence Livermore National Laboratory in Livermore, California, told Reuters that “The story out there that scientists do not know is the cause of climate change is wrong.” A large ice in western Antarctica melts and its collapse can raise the global sea level almost 2 meters, but it can take centuries.

Hottest on record
The last five years have been the five hottest since the record keeping began in the 1800s. The Earth has experienced 42 straight years (since 1977) with an above-average global temperature, according to the National Oceanic and Atmospheric Administration.
Based on five separate datasets that keep track of the Earth’s climate, the global average temperature for the first 10 months of 2018 was about 1.8 degrees above what it was at the end of the 19th century. It was then that the industry began to emit large amounts of greenhouse gases into the atmosphere.
Australia experienced summer heat in January this year. The city of Port Augusta reached the hottest day since record-keeping began in 1962 with a temperature of 121, according to Guardian .
The heat was so intense that it caused bats to fall off trees according to the Australian Broadcasting Corporation.
Carbon dioxide up 46%
Increasing amounts of carbon dioxide and other gases are released into the atmosphere by the industry, transport and energy production from burning fossil fuels increases what is called the planet’s natural greenhouse effect.
Carbon dioxide is the most common among all greenhouse gases produced by human activities related to the combustion of fossil fuels.
The atmospheric carbon dioxide level for March was 411.97 parts per million and continues to rise. It has now reached levels in the atmosphere that are not seen in 3 million years.
This is an increase of 46% from just before the industrial revolution in the 19th century, when the carbon dioxide content was about 280 parts per million. The levels began to rise as people began to burn large amounts of fossil fuels to run factories and heating homes, emissions of carbon dioxide and other greenhouse gases into the atmosphere.
Researchers say we should be able to keep a lively planet, we must lower the level to 350 parts per million.
A consequence of higher temperatures is the melting of the polar ice caps, causing sea levels to rise. The world’s oceans have risen about an inch over the past 50 years due to the melting of glaciers alone, a study published this month in the journal Nature .
The Earth’s glaciers now lose up to 390 billion tons of ice and snow a year, the study suggests.
Global warming has caused over 3 trillion tons of ice to melt from Antarctica in the last quarter and tripled ice loss there over the last decade, another study released in June
Business is burning under a dark smoky sky in Paradise on November 9.  Extreme weather events aggravated in part by climate change killed nearly 250 Americans and cost the nation at least $ 91 billion in 2018, according to the National Oceanic and Atmospheric Administration.
Unusual heat in the US West 2018 contributed to a catastrophic wild season that killed dozens of people. In monetary terms, Western states have endured their most costly firefighting season on record: $ 24 billion in damage.
Hurricanes Michael, which resulted in $ 25 billion in damage and Florence, with $ 24 billion in costs, were the two other major weather events in 2018.
New York City with Arkansas & # 39; weather
About the amount of carbon dioxide the atmosphere does not lower the temperature continues to increase. A study released in February charted how different climates in US cities will be in 60 years if greenhouse gas emissions continue.
The study Nature found that the future climate on average resembles that experienced by an area 528 miles south today.
That means New York City could have a climate of Arkansas in 2080. Minneapolis may be more like Kansas and San Francisco may have weather closer to Los Angeles than its current foggy climate. Other cities further south can experience climate with no modern equivalent in North America.
“The children who live today, like my daughter who is 12 years old, will see a dramatic transformation of the climate. It is already on its way,” says study director author Matt Fitzpatrick of the University of Maryland Center for Environmental Science.
