STATES CHRONICLE – Extreme weather, consisting of heat waves, droughts, and downpours, was related to human-made climate change. The lead author of the new study is Noah Diffenbaugh. He is a climate scientist at Stanford University, and he stated that the results of the study indicated that human actions are responsible for record-breaking weather events. This research is the first one to analyze the relation between climate change and extreme weather of the past decades.
Global warming is slowly damaging the whole planet, causing extreme weather events
Diffenbaugh together with his colleagues has unveiled that in more 80% of the heat records, there appeared an obvious sign of global warming. Global warming is determined by the burning of fossil fuels like oil, coal, and gas which discharge a lot of greenhouse gasses into the atmosphere. The unusual amount of carbon dioxide triggers an increase in atmosphere and oceans’ temperatures, supporting the atmosphere to retain more water vapors. All these factors cause a rise in global sea levels.
Diffenbaugh also pointed out that record-breaking precipitation can also be related to global warming, but, unfortunately, researchers did not have enough evidence to support this idea. Noah and his team indicated that human influence on the atmosphere had determined an increase in the wettest and driest weather events in approximately half of the areas. In the affected areas, the chances of extreme weather are greater with climate change than without it.
Burning fossil fuel triggers high amounts of carbon dioxide which affect the atmosphere
The lead author of the study claimed that the biggest increase in the chances of rough weather was identified at the tropics, consisting of dry events. The new research also established that due to the fact the sea ice record in the Arctic in 2012 was so low that it would have been hard to reach this extreme level without the contribution of global warming.
After a new record of an extreme heat wave, terrible drought or crucial flood, many people started wondering about human-made climate change and its role. Based on the data provided by the National Oceanic and Atmospheric Administration, extreme weather event attribution is meant to indicate how much credit should people assign to climate change and how much should go to random climate variability.
In the past, researchers avoided correlating individual weather events to global warming, differentiating between the challenges of disentangling human impact and the natural weather variability. How responsible do you think we are regarding global warming?
