US President Donald Trump's recent tweet about a severe winter storm hitting half of the country as evidence that climate change is a hoax is misguided and misinformed. The storm, which will bring freezing temperatures and heavy snow to millions of Americans, has no connection to the supposed "hoax" claimed by Trump.
In reality, research suggests that an unusual Arctic cold snap can occur when the polar vortex weakens or stretches out. This phenomenon allows frigid air from the Arctic to move south into the US, leading to extreme weather events like the current winter storm. What's more, scientists have found that global warming could be accelerating this process by altering the polar vortex.
The problem is, Trump seems to ignore the overwhelming evidence of human-caused climate change. The Arctic is warming at an alarming rate – up to four times faster than the rest of the planet – which is causing changes in sea ice levels and leading to disruptions in the polar vortex. This means that winter storms like the one currently hitting the US are becoming more frequent and intense.
Moreover, a single storm event in one region tells us very little about long-term global climate trends. Climate records show that winters are warming faster than other seasons in the US, leading to glacier loss and shifting seasonal norms. The trend is clear: winter cold snaps have shortened by six days on average since 1970, while record-breaking hot days have become more common.
Trump's attempt to use this storm as evidence against climate science only serves to underscore his long-standing skepticism towards established scientific consensus. Climate change is real, and its impacts are being felt across the globe. Rather than using extreme weather events as a "proof" of the supposed hoax, Trump should be working with scientists and policymakers to develop solutions that address the root causes of this crisis.
