‘The projections get more stark’: Scientists warn of 10 million deaths, rise in infectious diseases and even armed conflict due to climate change
Ten million people are “likely to die” due to extreme temperatures if world leaders fail to agree significant cuts in greenhouse gas emissions by 2030, a report has warned.
Agricultural output could also drop by 30% by 2050 – even as the amount of food needed by growing populations is predicted to rise by 50%, according to international affairs think tank Chatham House.
The report produced for governments ahead of COP26, the UN climate meeting in Glasgow this November, said severe impacts of climate change will be “locked in” from 2040 unless greenhouse gas emissions “drastically” decline before 2030.

How to prepare for extreme weather
Corn crops are especially likely to suffer, with the think tank predicting at least a 10% drop in yields in the US, China, Brazil and Argentina, where most crops are grown.
More than 400m people would be “unable to work outside” by the 2030s, with 10m deaths predicted due to “heat stress”, the report said.
By 2040, researchers said almost 700m people each year would probably be exposed to severe droughts lasting at least six months – and by 2050, more than 70% of people in every region of the world would probably experience heatwaves.
The amount of flooding would surge by the turn of the next century, with the study’s authors warning nearly 200m people worldwide would probably be living below the 100-year flood level – the level at which water begins to overflow into the surrounding area.
Almost 60m people would likely be affected by river flooding due to the rise in the relative sea level, the report said.
The authors said the probability of flood events that currently happen once every 100 years increases with just a one-metre rise in the relative sea level, jumping by 40 times for Shanghai, 200 times for New York and 1000 times for Kolkata.

Is UK prepared for extreme weather?
They said the current pace of global decarbonisation efforts mean the world is on track for at least 2.7C in warming by the end of the century – well above the 1.5C target.
The report noted that new proposals by some governments to further cut emissions fall far short of what is required to meet the target, while several major economies are yet to commit to any further emission reduction goals.
At COP21 in Paris in 2015, countries agreed to try to limit global warming to 2C above pre-industrial levels to curb the climate crisis.
Dr Daniel Quiggin, a senior research fellow at Chatham House who co-authored the report, said: “There remains a real opportunity yet a closing window for greatly increased ambition from all governments to prevent the most catastrophic impacts of climate change.”
He added that there is also “the increasing possibility that climate-related events trigger a sequence of connected incidents across regions and sectors which cause trade disruption, political instability, increased migration, an increase in infectious diseases or even armed conflict”.

Jamie Peters, director of campaigning at Friends of the Earth, called the report “horrifying” but said he does not think it is possible to be “too late” to respond to climate change.
“Every point of a degree is a question of lives,” he told Sky News.
He urged the UK government to “get its act together” and drop its support for all fossil fuel projects – like airport expansions, coal mines and gas projects.
He said doing this would give Britain the legitimacy needed to demand action from other countries.
The speed of climate change has shocked many people in the past,” he said. “The science has been clear and the projections get more and more stark.”

US blocks Palestinian President Mahmoud Abbas and 80 other officials from United Nations’ annual meeting in New York
Palestinian President Mahmoud Abbas and 80 other officials have been blocked from attending September’s annual meeting of the United Nations General Assembly in New York.
US secretary of state Marco Rubio has revoked the US visas of delegates from the Palestinian Authority (PA) and Palestine Liberation Organisation (PLO), and denied others from applying for one.
It is the latest step by Donald Trump’s administration to target Palestinians with visa restrictions, and follows the suspension of a programme to allow injured children from Gaza to receive treatment in the US.

“It is in our national security interests to hold the PLO and PA accountable for not complying with their commitments, and for undermining the prospects for peace,” a statement from the US State Department said.
It added that, to be considered partners for peace, both groups “must consistently repudiate terrorism, and end incitement to terrorism in education, as required by US law and as promised by the PLO”.
Offensive will cause ‘intolerable deaths’
Several US allies, including France, Malta, and Australia have announced plans to recognise Palestine as a state at September’s United Nations General Assembly. Canada and the UK will too, unless Israel meets certain conditions.
Israel declared Gaza’s largest city a dangerous combat zone on Friday.
The army launched a planned offensive that has drawn international condemnation.

Thick smoke rises from Gaza City after Israeli strikes
Foreign ministers from Iceland, Ireland, Luxembourg, Norway, Slovenia and Spain released a joint statement saying the military operations in Gaza City will cause “intolerable deaths of innocent Palestinian civilians”.

The Palestinian ambassador to the United Nations (UN), Riyad Mansour, said Mr Abbas had planned to lead the delegation to the UN meetings and was expected to address the general assembly at the general debate, which begins on 23 September.
He was also expected to attend a high-level meeting co-chaired by France and Saudi Arabia on 22 September about a two-state solution, a broad idea involving Israel coexisting with an independent Palestinian state.
The State of Palestine is an observer member of the UN, meaning it can speak at meetings but not vote on resolutions.

US decision ‘contravenes international law’
The Palestinian Authority “expressed its deep regret and astonishment” at the visa decision, calling it “a violation of US commitments” as the host of the UN, and claiming it “contravenes international law”.
UN spokesman Stephane Dujarric said the world body would be seeking clarification in the “hope that this will be resolved”.

The State Department said that the Palestinian Authority’s mission to the UN, comprising officials who are permanently based there, would not be included in the restrictions.
Under a 1947 UN agreement, the US is generally required to allow access for foreign diplomats to the UN in New York.
But Washington has said it can deny visas for security, extremism and foreign policy reasons.

Brazil implores businesses to attend major climate summit, despite ‘second thoughts’ amid Trump backlash
The Brazilian hosts of the biggest climate meeting of the year have implored businesses to attend in November, amid concerns some are backing away from the climate agenda into the shadow of Donald Trump.
In an interview with Sky News, Ana Toni, chief executive of the COP30 climate summit in November, admitted some companies were having “second thoughts” about the global switch to green economies because policymakers were creating uncertainty.
The US President Donald Trump has been attacking wind farms and waging tariff wars that could slow the transition to green energy.
Banks including HSBC and Barclays have ditched a net zero alliance set up just four years ago by Mark Carney, now the Canadian Prime Minister.

But even before Trump took office, tech companies were quietly dropping climate targets to prioritise energy-hungry AI, and other businesses were “greenhushing” their climate initiatives for fear of backlash.
In this environment, there are fears fewer business leaders will attend the annual talks, which are also being hosted in a city on the edge of the Amazon that hasn’t enough hotel rooms.
On Friday, the COP30 team wrote to business leaders urging them to “step forward, not back” and travel to Belem, despite “logistical challenges” and the “background of systemic uncertainty”.
Ana Toni told Sky News: “We are very concerned that the enabling conditions must be there so that the private sector can also deliver where they do best, which is bringing in technology, bringing innovation and accelerating the process of decarbonisation.”
In August the share price of Danish wind farm developer plummeted after the US halted its Rhode Island wind farm, while the British Tories and Reform parties are also attacking net zero.

But Ms Toni there is “nothing to panic [about], because we can see that the transition is inevitable,” citing major progress in China, India and Europe and Brazil.
Referring to the US’s withdrawal from the COP process, she said: “198 countries minus one is not zero. And we will put all our efforts of working with the 197 countries that want to go forward and want to protect their population.”
“Climate action is not only [still] cool, it is necessary,” Ms Toni said.
“We all need to face reality. We are going through a huge climate crisis… If you’re not part of the solution, you’re part of the problem. Companies understand that.”
