From heat waved to many catastrophic floods, the extreme weather conditions found these days has been caused by human-induced climate changes especially global warming.
But, on the other hand, it is impossible to blame the individual factors like global warming since there are many physical factors that may cause damage. Many scientists are trying to determine the extent to which the climate change may cause severe changes.
This question was raised by Noah Diffenbaugh, a professor of Earth system science from Standford’s School of Earth, Energy & Environmental Sciences and his team. These group of researchers has further extended their findings on a global scale. According to a new study published in the journal Proceedings of the National Academy of Sciences.
Global warming is characterized by an increase in the Earth’s temperature and the ocean temperature that indirectly causes irreversible climate changes. The team of researchers has designed a four-step framework to determine whether the global warming has caused record-breaking climate events globally. In this framework, by evaluating hottest, wettest and the driest events it was seen that global warming caused by human-induced greenhouse gasses have increased the probability and intensity of record-breaking climate events observed in more than 80% of the planet’s surface.
The study reveals that anthropogenic global warming has led to the hottest temperatures seen in the hottest months and on the hottest day.
How is the Earth coping up with the effects of Global Warming?
Apart from human-induced climate changes, the rise in the amount of carbon dioxide and other greenhouse emissions caused by burning wood and fossil fuels, deforestation and natural conditions like volcanoes, cyclones have also contributed to the global warming that is observed since last 5 decades.
The amount of carbon dioxide observed today has reached the peak level in 650,000 years. The global warming has increased by 1.7 degrees Fahrenheit since 1880. The Arctic ocean’s ice cover have been reduced by 13.3 percent in last decade and the sea level has increased by 7 inches.
