Extreme heat is a health crisis, Columbia experts say
The record-breaking warmth Earth endured in the course of the summer time of 2022 will likely be repeated and not using a strong worldwide effort to deal with local weather change, a panel of scientists warned Monday.
Warmth-related deaths, wildfires, excessive rainfall, and protracted drought are anticipated to develop into more and more extreme as each ocean and atmospheric temperatures proceed to rise, the specialists mentioned. Even when all greenhouse gasoline emissions ceased at present, Earth will proceed to heat for a number of many years.
The presentation, “Earth Sequence Digital: Blazing Temperatures, Damaged Information,” featured a multidisciplinary panel of scientific specialists from Columbia College.
Radley Horton, a analysis professor at Columbia’s Lamont-Doherty Earth Observatory, said that human-induced local weather change has precipitated the worldwide common atmospheric temperature to heat by about 2 levels (1.1 levels Celsius) within the final a number of many years.
“One of many key takeaways is that a little bit little bit of change in international temperature has an unlimited influence,” mentioned Horton. A number of the most important penalties embody longer and extra intense warmth waves which can be hitting more and more bigger areas.
Moreover, Horton mentioned, sure local weather fashions have underestimated simply how excessive sure occasions will be, such because the European warmth wave of 2022 and the Pacific Northwest warmth wave of 2021.
“We’re locked into quite a lot of extra local weather hazards, there isn’t any approach round it,” mentioned Horton.
Diana Hernandez, Affiliate Professor of Sociomedical Sciences on the Columbia Mailman College of Public Well being, is researching how sure vulnerabilities, akin to medical situations or entry to vitality, might be affected by altering local weather domestically and internationally. The anticipated impacts embody shade inequalities, city warmth islands, and inequitable entry to energy-powered medical units.
“The local weather is altering, and we’re not tailored to have the ability to take care of it from a well being perspective,” mentioned Cecilia Sorensen, a doctor and affiliate professor of Environmental Well being Sciences on the Columbia College Medical Middle.
Sorensen famous that she and colleagues referred to summer time as “trauma season” early in her profession, even earlier than she targeted on the well being impacts of local weather change. “We used to get inundated with sufferers … individuals coming in with coronary heart assaults and bronchial asthma exacerbations.”
Regardless of the foreboding local weather projections, the panelists expressed hope that appreciable strides will be made to reduce future local weather impacts associated to excessive warmth.
Hernandez mentioned a community-focused strategy, particularly with an emphasis on engagement that’s inclusive, will likely be profitable in implementing a variety of local weather adaptation methods.
Sorenson mentioned one answer that may be carried out by hospitals is creating emergency room protocols to deal with a big inflow of sufferers affected by warmth stroke or associated situations throughout excessive climate. Improved communications are additionally wanted to extend consciousness in regards to the medical dangers of utmost warmth and the way impacts will be prevented, she mentioned.
“Inside the issue lies the answer,” mentioned Sorensen.

US Supreme Court critical of TikTok arguments against looming ban
Justices at the United States Supreme Court have signalled scepticism towards a challenge brought by the video-sharing platform TikTok, as it seeks to overturn a law that would force the app’s sale or ban it by January 19.
Friday’s hearing is the latest in a legal saga that has pitted the US government against ByteDance, TikTok’s parent company, in a battle over free speech and national security concerns.
The law in question was signed in April, declaring that ByteDance would face a deadline to sell its US shares or face a ban.
The bill had strong bipartisan support, with lawmakers citing fears that the Chinese-based ByteDance could collect user data and deliver it to the Chinese government. Outgoing US President Joe Biden ultimately signed it into law.
But ByteDance and TikTok users have challenged the law’s constitutionality, arguing that banning the app would limit their free speech rights.
During Friday’s oral arguments, the Supreme Court seemed swayed by the government’s position that the app enables China’s government to spy on Americans and carry out covert influence operations.
Conservative Justice Samuel Alito also floated the possibility of issuing what is called an administrative stay that would put the law on hold temporarily while the court decides how to proceed.
The Supreme Court’s consideration of the case comes at a time of continued trade tensions between the US and China, the world’s two biggest economies.
President-elect Donald Trump, who is due to begin his second term a day after the ban kicks in, had promised to “save” the platform during his presidential campaign.
That marks a reversal from his first term in office, when he unsuccessfully tried to ban TikTok.
In December, Trump called on the Supreme Court to put the law’s implementation on hold to give his administration “the opportunity to pursue a political resolution of the questions at issue in the case”.
Noel Francisco, a lawyer for TikTok and ByteDance, emphasised to the court that the law risked shuttering one of the most popular platforms in the US.
“This act should not stand,” Francisco said. He dismissed the fear “that Americans, even if fully informed, could be persuaded by Chinese misinformation” as a “decision that the First Amendment leaves to the people”.
Francisco asked the justices to, at minimum, put a temporary hold on the law, “which will allow you to carefully consider this momentous issue and, for the reasons explained by the president-elect, potentially moot the case”.
‘Weaponise TikTok’ to harm US
TikTok has about 170 million American users, about half the US population.
Solicitor General Elizabeth Prelogar, arguing for the Biden administration, said that Chinese control of TikTok poses a grave threat to US national security.
The immense amount of data the app could collect on users and their contacts could give China a powerful tool for harassment, recruitment and espionage, she explained.
China could then “could weaponise TikTok at any time to harm the United States”.
Prelogar added that the First Amendment does not bar Congress from taking steps to protect Americans and their data.
Several justices seemed receptive to those arguments during Friday’s hearing. Conservative Chief Justice John Roberts pressed TikTok’s lawyers on the company’s Chinese ownership.
“Are we supposed to ignore the fact that the ultimate parent is, in fact, subject to doing intelligence work for the Chinese government?” Roberts asked.
“It seems to me that you’re ignoring the major concern here of Congress — which was Chinese manipulation of the content and acquisition and harvesting of the content.”
“Congress doesn’t care about what’s on TikTok,” Roberts added, appearing to brush aside free speech arguments.
Left-leaning Justice Elena Kagan also suggested that April’s TikTok law “is only targeted at this foreign corporation, which doesn’t have First Amendment rights”.
TikTok, ByteDance and app users had appealed a lower court’s ruling that upheld the law and rejected their argument that it violates the US Constitution’s free speech protections under the First Amendment.
