Heat, air pollution, disease: How climate change affects health

  • The latest round of UN climate summit begin next week during what is expected to be the hottest year in recorded history
  • The COP29 talks will be held in Azerbaijan as the world continues to emit increasing levels of planet-heating fossil fuels

PARIS: Record-breaking heat, extreme weather events, air pollution and the spread of infectious disease: climate change poses an already vast yet rising threat to the health of humans around the world, experts warn.
The latest round of UN climate talks begin next week during what is expected to be the hottest year in recorded history — and in the shadow of climate skeptic Donald Trump’s re-election as US president.
The COP29 negotiations will be held in Azerbaijan as the world continues to emit increasing levels of planet-heating fossil fuels, even as many nations have been lashed by devastating floods, droughts, heatwaves and storms.

“Climate change is making us sick, and urgent action is a matter of life and death,” the World Health Organization warned this week.
Here are some of the ways that global warming affects health.
The EU’s climate monitor said this week that 2024 is “virtually certain” to surpass last year to become the hottest year in recorded history. It is also expected to be the first year that is more than 1.5 degrees Celsius warmer than the 1850-1900 pre-industrial average.
Out of 15 ways that climate change impacts health being tracked by experts as part of The Lancet Countdown, 10 have now “reached concerning new records,” according to the group’s latest report.
The number of over-65s who died from heat has risen by 167 percent since the 1990s, just one of the recent all-time highs, the report said.
Extreme heat leads to numerous health risks such as kidney disorders, strokes, adverse pregnancy outcomes, cardiovascular and respiratory diseases, organ failure and ultimately death.

Jeni Miller, executive director of the Global Climate and Health Alliance, said “this year has underlined the growing impacts of a warming climate on people’s health and wellbeing.”
She pointed to extreme heat leading to 700 deaths and more than 40,000 cases of heat stroke in India, “climate-exacerbated” rains causing a dam to collapse in Nigeria killing 320, and 48 out of 50 US states “experiencing moderate or worse drought.”
Spain is meanwhile still recovering from its deadliest floods in a generation, while parts of the United States and Cuba are picking up the pieces after recent hurricanes.
Droughts, floods and other extreme weather events are also expected to hit global crops, leading to rising hunger in many regions.
Almost all — 99 percent — of the world’s population breathes air that exceeds the World Health Organization’s guidelines for air pollution.
This pollution has been found to increase the risk of respiratory diseases, strokes, heart disease, lung cancer, diabetes and other health problems, posing a threat that has been compared to tobacco.
Almost seven million premature deaths a year are linked to air pollution, according to the WHO.

Just last week, Pakistan’s second-biggest city Lahore recorded air pollution at 40 times the level deemed acceptable by the WHO.
In better news, the Lancet Countdown report found that deaths from fossil fuel-related air pollution fell by nearly seven percent from 2016 to 2021, mainly due to efforts to reduce pollution from burning coal.
The changing climate means that mosquitoes, birds and mammals will roam beyond their previous habitats, raising the threat that they could spread infectious diseases with them.
Dengue, chikungunya, Zika, West Nile virus and malaria are all mosquito-borne diseases that could spread wider in a warming world.
The transmission risk of one dengue-spreading mosquito has risen by 43 percent over the last 60 years, according to the Lancet Countdown. A new global record of over five million dengue cases was recorded last year.
Storms and floods create stagnant water that are breeding grounds for mosquitoes, and also increase the risk of water-borne diseases such as cholera, typhoid and diarrhea.

War powers resolution fails in Senate as 2 Republicans bow to Trump pressure

WASHINGTON: Senate Republicans voted to dismiss a war powers resolution Wednesday that would have limited President Donald Trump’s ability to conduct further attacks on Venezuela after two GOP senators reversed course on supporting the legislation.
Trump put intense pressure on five Republican senators who joined with Democrats to advance the resolution last week and ultimately prevailed in heading off passage of the legislation. Two of the Republicans — Sens. Josh Hawley of Missouri and Todd Young of Indiana — flipped under the pressure.
Vice President JD Vance had to break the 50-50 deadlock in the Senate on a Republican motion to dismiss the bill.
The outcome of the high-profile vote demonstrated how Trump still has command over much of the Republican conference, yet the razor-thin vote tally also showed the growing concern on Capitol Hill over the president’s aggressive foreign policy ambitions.
Democrats forced the debate after US troops captured Venezuelan leader Nicolás Maduro in a surprise nighttime raid earlier this month
“Here we have one of the most successful attacks ever and they find a way to be against it. It’s pretty amazing. And it’s a shame,” Trump said at a speech in Michigan Tuesday. He also hurled insults at several of the Republicans who advanced the legislation, calling Sen. Rand Paul of Kentucky a “stone cold loser” and Sens. Lisa Murkowski of Alaska and Susan Collins of Maine “disasters.” Those three Republicans stuck to their support for the legislation.
Trump’s latest comments followed earlier phone calls with the senators, which they described as terse. The president’s fury underscored how the war powers vote had taken on new political significance as Trump also threatens military action to accomplish his goal of possessing Greenland.
The legislation, even if it had cleared the Senate, had virtually no chance of becoming law because it would eventually need to be signed by Trump himself. But it represented both a test of GOP loyalty to the president and a marker for how much leeway the Republican-controlled Senate is willing to give Trump to use the military abroad. Republican angst over his recent foreign policy moves — especially threats of using military force to seize Greenland from a NATO ally — is still running high in Congress.
Two Republicans reconsider
Hawley, who helped advance the war powers resolution last week, said Trump’s message during a phone call was that the legislation “really ties my hands.” The senator said he had a follow-up phone call with Secretary of State Marco Rubio Monday and was told “point blank, we’re not going to do ground troops.”
The senator added that he also received assurances that the Trump administration will follow constitutional requirements if it becomes necessary to deploy troops again to the South American country.
“We’re getting along very well with Venezuela,” Trump told reporters at a ceremony for the signing of an unrelated bill Wednesday.
As senators went to the floor for the vote Wednesday evening, Young also told reporters he was no longer in support. He said that he had extensive conversations with Rubio and received assurances that the secretary of state will appear at a public hearing before the Senate Foreign Relations Committee.
Young also shared a letter from Rubio that stated the president will “seek congressional authorization in advance (circumstances permitting)” if he engaged in “major military operations” in Venezuela.
The senators also said his efforts were also instrumental in pushing the administration to release Wednesday a 22-page Justice Department memo laying out the legal justification for the snatch-and-grab operation against Maduro.
That memo, which was heavily redacted, indicates that the administration, for now, has no plans to ramp up military operations in Venezuela.
“We were assured that there is no contingency plan to engage in any substantial and sustained operation that would amount to a constitutional war,” according to the memo signed by Assistant Attorney General Elliot Gaiser.
Trump’s shifting rationale for military intervention
Trump has used a series of legal arguments for his campaign against Maduro.
As he built up a naval force in the Caribbean and destroyed vessels that were allegedly carrying drugs from Venezuela, the Trump administration tapped wartime powers under the global war on terror by designating drug cartels as terrorist organizations.
The administration has claimed the capture of Maduro himself was actually a law enforcement operation, essentially to extradite the Venezuelan president to stand trial for charges in the US that were filed in 2020.
Paul criticized the administration for first describing its military build-up in Caribbean as a counternarcotics operation but now floating Venezuela’s vast oil reserves as a reason for maintaining pressure.
“The bait and switch has already happened,” he said.
Trump’s foreign policy worries Congress
Lawmakers, including a significant number of Republicans, have been alarmed by Trump’s recent foreign policy talk. In recent weeks, he has pledged that the US will “run” Venezuela for years to come, threatened military action to take possession of Greenland and told Iranians protesting their government that ” help is on its way.”
Senior Republicans have tried to massage the relationship between Trump and Denmark, a NATO ally that holds Greenland as a semi-autonomous territory. But Danish officials emerged from a meeting with Vance and Rubio Wednesday saying a “fundamental disagreement” over Greenland remains.
“What happened tonight is a roadmap to another endless war,” Senate Democratic leader Chuck Schumer said at a news conference following the vote.
More than half of US adults believe President Donald Trump has “gone too far” in using the US military to intervene in other countries, according to a new AP-NORC poll.
House Democrats have also filed a similar war powers resolution and can force a vote on it as soon as next week.
How Republican leaders dismissed the bill

Last week’s procedural vote on the war powers resolution was supposed to set up hours of debate and a vote on final passage. But Republican leaders began searching for a way to defuse the conflict between their members and Trump as well as move on quickly to other business.
Once Hawley and Young changed their support for the bill, Republicans were able to successfully challenge whether it was appropriate when the Trump administration has said US troops are not currently deployed in Venezuela.
“We’re not currently conducting military operations there,” said Senate Majority Leader John Thune in a floor speech. “But Democrats are taking up this bill because their anti-Trump hysteria knows no bounds.”
Democratic Sen. Tim Kaine, who has brought a series of war powers resolutions this year, accused Republicans of burying a debate about the merits of an ongoing campaign of attacks and threats against Venezuela.
“If this cause and if this legal basis were so righteous, the administration and its supporters would not be afraid to have this debate before the public and the United States Senate,” he said in a floor speech.
