The more accurate estimates project a gloomier global warming scenario, says new study

[vc_row][vc_column][vc_column_text]Global temperatures are likely to rise by 4C, drowning islands, worsening water scarcity and creating prolonged heat waves

The gloomier the prediction, the more realistic it is – that is the conclusion of a new study on climate change models to assess future warming of the planet.

The findings, published Wednesday in the journal Nature, suggest that the target to keep global temperatures from rising by two degrees Celsius (over pre-industrial era, before 1850 CE), reiterated in Paris Climate Agreement, may be too optimistic and ambitious as it relies on projections that underestimate how much the planet will warm and, by extension, underestimate the cuts in greenhouse gas emissions needed to stave off catastrophic impacts of climate change.

The study, by Patrick Brown and Ken Caldeira of the Carnegie Institution for Science in Stanford, California, examined climate change simulations, or “models,” that researchers use to project the future of the planet based on the physical equations that govern the behaviour of the atmosphere and oceans.

Co-author of the study Patrick Brown said, “We find that the models that do the best at simulating the recent past project more warming.”

“Our study indicates that if emissions follow a commonly used business-as-usual scenario, there is a 93 per cent chance that global warming will exceed 4C by the end of this century,” said Dr Ken Caldeira, who co-authored the new study.

This is a marked increase in probability of such warming over past estimates, which placed it at 62 per cent.

A warming of 4C would have severe impacts, drowning small islands, eliminating coral reefs, exacerbating water scarcity, loss of biodiversity and creating prolonged heat waves around the world, scientists say.

The United Nation’s Intergovernmental Panel on Climate Change (IPCC) puts the top range for warming between 3.2C to 5.9C by 2100, giving equal weightage to about three dozen models used by researchers to understand global warming and its impacts.

Climate models are tools for scientists attempting to understand the impacts of greenhouse-gas emissions. They are constructed using fundamental knowledge of physics and the world’s climate. But, given the complexity of the climate system, there is disagreement about how best to model key aspects of it and scientists have produced dozens of climate models predicting a range of different global warming outcomes resulting from greenhouse-gas emissions.

Climate change deniers and opponents of carbon regulation have used these differences in projections to label the models unreliable, inaccurate or just plain wrong.

Patrick Brown and Ken Caldeira looked for a way to narrow the uncertainty by determining which models were better. To do this, they looked at the models that were best at simulating climate patterns in the recent past – that is, they saw how the models predicted recent climate conditions and compared that to what actually happened.

“It makes sense that the models that do the best job at simulating today’s observations might be the models with the most reliable predictions,” said Dr Caldeira.

“The IPCC uses a model democracy—one model, one vote—and that’s what they’re saying is the range,” Brown explained. “We’re saying we can do one better. We can try to discriminate between well- and poor-performing models. We’re narrowing the range of uncertainty.”

“… if you take the best models, those are the ones projecting the most warming in the future,” he said.

In a worst-case scenario, the study finds that global temperatures could rise 15 percent more than projected by the IPCC – 0.5C more in the 3.2C-5.9C range – by the end of this century.

The research by Dr Brown and Dr Caldeira focuses specifically on models of energy flow from Earth to space, of the balance of incoming and outgoing radiation that ultimately determines the Earth’s temperature, as measured by satellites. They found the models that do the best job capturing the Earth’s actual “energy imbalance,” as the authors put it, are also the ones that simulate more warming in the planet’s future.

They suggest that the amount of sunlight reflected away from the planet by clouds will decrease as the world gets warmer, increasing the magnitude of climate change.

While the findings were appreciated by scientists, they also raised a point of caution. “This is only one line of evidence. Other lines of evidence based on the historically observed warming suggest the simulations with slightly cooler projections may fit best. We need to consider all the lines of evidence before we jump to conclusions,” Professor Piers Forster, a climate-change specialist at the University of Leeds who was not involved in the study told ‘Independent’.[/vc_column_text][/vc_column][/vc_row]

Kremlin denies US media reports on Donald Trump’s phone call with Vladimir Putin

Donald Trump said on the campaign trail that he could end the fighting within hours and has indicated he would talk directly with Russian President Putin.

Kremlin denies US media reports on Donald Trump’s phone call with Vladimir Putin

The Kremlin today denied a US media report that Russian President Vladimir Putin and US president-elect Donald Trump had spoken on the phone last week about the Ukraine conflict.

Earlier on Sunday, The Washington Post reported that Donald Trump spoke to Vladimir Pution on call, urging him not to inflame the conflict. Speaking on the matter, Kremlin spokesman Dmitry Peskov told the media that the report was completely false information, and denied any phone call took place.

It was reported that US President-elect Donald Trump has spoken to Russian President Vladimir Putin and urged him not to escalate the war in Ukraine. It said that Donald Trump held the call from his Mar-a-Lago estate in Florida on Thursday, just days after his stunning election victory over Democratic rival Kamala Harris. The report also mentioned that both the leaders expressed an interest in further conversations to discuss the resolution of Ukraine’s war soon.

Notably, Donald Trump said on the campaign trail that he could end the fighting within hours and has indicated he would talk directly with Russian President Putin. However, the US President elect has not said how he intends to strike a peace deal or what terms he is proposing.

Donald Trump’s election is seen as carrying the potential to upend the almost three-year Ukraine conflict, as he insists on a quick end to the fighting and casts doubt on Washington’s multi-billion dollar support for Kyiv.

Meanwhile, Ukrainian President Volodymyr Zelensky spoke with Trump on Wednesday, with the Republican’s billionaire backer Elon Musk also notably joining them on the call. Volodymyr Zelensky described the call as excellent, adding that he and Trump had agreed to maintain close dialogue and advance our cooperation.

Additionally, the outgoing Democratic administration of President Joe Biden has confirmed that it will send as much aid as possible to Ukraine before Trump’s inauguration on January 20.

Joe Biden’s National Security Advisor Jake Sullivan said the White House aims to put Ukraine in the strongest possible position on the battlefield so that it is ultimately in the strongest possible position at the negotiating table.

India calls out Canada’s move to ban Australia Today for airing S Jaishankar’s press conference

The MEA said that these actions yet again highlight the hypocrisy of Canada towards freedom of speech.

India calls out Canada’s move to ban Australia Today for airing S Jaishankar's press conference

A few hours after Australia Today aired External Affairs Minister S Jaishankar’s press conference in Australia, Canada banned the outlet. The External Affairs Minister gave remarks on the India-Canada diplomatic standoff. 

Reacting to this, India on Thursday said it was surprised by Canada’s move to ban the outlet and emphasized that it highlighted Ottawa’s hypocrisy towards freedom of speech. Australia Today, which is an important outlet for the Indian community in the country, had aired the joint press conference of S Jaishankar and his Australian counterpart Penny Wong in Canberra.

In a weekly media briefing, MEA spokesperson Randhir Jaiswal said that they understand that the social media handles, pages of this particular outlet, which is an important diaspora outlet, have been blocked and are not available for viewers in Canada. He continued that this happened just an hour or a few hours after this particular handle carried the press conference of S Jaishankar with Penny Wong. He called out the incident, mentioning that they are surprised, and the matter looks strange to them.

He further underlined that these are the actions which yet again highlight the hypocrisy of Canada towards freedom of speech. He noted that the External Affairs Minister spoke about three things: Canada making allegations and a pattern had developed without any specific evidence, surveillance of Indian diplomats in Canada, which he termed as unacceptable, and  the political space which has been given in Canada to anti-India elements. 

With this one can draw conclusions, why Australia Today channel was blocked by Canada, the spokesperson said. Australia Today focuses on news and analytical pieces related to the Indian community in Australia and elsewhere across the world.

This incident follows days after devotees were attacked by pro-Khalistani at a Hindu temple in Canada’s Brampton, with S Jaishankar calling it deeply concerning. Furthermore, Prime Minister Narendra Modi also condemned the attack and said that there were cowardly attempts to intimidate Indian diplomats.

The diplomatic standoff between India and Canada began in September last year when Canadian Prime Minister Justin Trudeau alleged that Indian government agents might have been involved in the killing of Khalistani terrorist Hardeep Singh Nijjar, a claim outrightly rejected by New Delhi.

Later in October 2024, ties between both the countries nosedived when Canada termed the Indian High Commissioner a person of interest in its investigation into Nijjar’s murder. Issuing a strongly worded statement, India dismissed the fresh charge and recalled the envoy and some diplomats, while expelling six Canadian officials, including Canada’s acting High Commissioner.

PM Modi congratulates Donald Trump on winning US President election

The Prime Minister urged Trump to work for the betterment of the people and to promote global peace, stability and prosperity.

Prime Minister Narendra Modi on Wednesday congratulated Donald Trump on winning the 2024 US Presidential election and said he is looking forward to renewing their collaboration to further strengthen the India-US partnership.

The Prime Minister urged Trump to work for the betterment of the people and to promote global peace, stability and prosperity.

“Heartiest congratulations my friend @realDonaldTrump on your historic election victory. As you build on the successes of your previous term, I look forward to renewing our collaboration to further strengthen the India-US Comprehensive Global and Strategic Partnership. Together, let’s work for the betterment of our people and to promote global peace, stability and prosperity,” PM Modi posted on his X handle.

With the results being announced for the 2024 US election on November 6, Trump became the 47th President of the United States.

Former US President Trump appeared to be on track for a remarkable political comeback in the White House race. Projections suggested that he was poised to secure the necessary 270 electoral college votes, effectively blocking Democratic candidate Kamala Harris from winning the election.

The relationship between Trump and Modi has been characterised by robust diplomatic ties, strategic collaboration, and a noticeable personal rapport. Their friendship was prominently displayed during major events such as “Howdy, Modi” in Houston in 2019 and “Namaste Trump” in Ahmedabad in 2020, where they addressed large audiences and expressed their mutual respect.

On a strategic level, Trump and Modi found common ground in matters of defense and security, both adopting a strong stance against terrorism, which reinforced their alliance, particularly concerning threats from Pakistan.

As he approaches a notable victory in the US election, Republican Presidential candidate Trump expressed gratitude to his supporters today, calling it a magnificent victory for the American people. He also referenced the assassination attempt on July 13, stating, “God spared my life for a reason.”

The 78-year-old candidate is currently projected to secure 267 electoral college votes, just three shy of the decisive 270, while his opponent, incumbent Vice President Kamala Harris, holds 224 electoral votes.

Trump described the Republican campaign as the greatest political movement of all time, asserting, “We are going to help our country heal, secure our borders, and we made history for a reason tonight. This is an incredible political victory. I want to thank the American people. I will fight for you and your family with every breath I have.”

He noted that Democrats are now looking at a projected total of 315 electoral votes.
