World May Exhaust 1.5 Degree Celsius Carbon Budget In 3 Years: Scientists
New Delhi: If the world continues to release carbon dioxide at the current rate, the carbon budget for limiting global warming to 1.5 degrees Celsius will be exhausted in just over three years, according to an international group of scientists. The carbon budget refers to the total amount of carbon dioxide the planet can emit while still having a good chance of staying below a certain temperature threshold. In this case, the limit is 1.5 degrees Celsius, which countries agreed to at the Paris climate conference in 2015. Exceeding the carbon budget does not mean the 1.5-degree limit will be crossed immediately. It means the world is on course to surpass it very soon unless emissions are drastically cut. The latest "Indicators of Global Climate Change" study, published in the journal Earth System Science Data, also found that the carbon budget for 2 degrees Celsius could be exceeded by 2048 if current levels of CO2 emissions continue. Scientists said human activities have led to the release of around 53 billion tonnes of carbon dioxide equivalent (Gt CO2e) into the atmosphere every year over the past decade. This is mainly due to increasing emissions from burning fossil fuels and deforestation. In the last 10 years (2015 to 2024), the Earth's temperature was 1.24 degrees Celsius higher than it was before the industrial era began. Scientists say 1.22 degrees Celsius of this warming was caused by human activities. The year 2024 was the hottest on record and marked the first calendar year with a global average temperature more than 1.5 degrees Celsius above the 1850-1900 baseline, the period before human activities such as fossil fuel use began significantly affecting the climate. A permanent breach of the 1.5-degree Celsius target in the Paris Agreement refers to sustained warming over a 20 to 30-year period. Last month, the World Meteorological Organization said there is a 70 per cent chance that the average global temperature between 2025 and 2029 will exceed pre-industrial levels by more than 1.5 degrees Celsius. In 2022, the UN Intergovernmental Panel on Climate Change (IPCC) said the world must cut greenhouse gas emissions by 43 per cent by 2030, compared to 2019 levels, to keep the temperature rise within 1.5 degrees Celsius since the Industrial Revolution. However, IPCC Chair Jim Skea told PTI in an interview in March that the 43 per cent reduction target is now outdated due to a lack of action, meaning the actual reduction needed is even higher.

'We are not in crisis': chair of IPCC climate body to AFP
Jim Skea insists the IPCC, the UN climate panel he chairs, is not in crisis and remains relevant despite criticism it is too slow in publishing its landmark scientific reports on climate change. In an interview with AFP in Paris, the British sustainable energy professor addressed divisions within the IPCC, the US retreat on climate cooperation, and record-breaking global temperatures. Q: At a recent meeting in Hangzhou, China, the IPCC failed to agree on a publication timeline for its next critical reports. Is the institution in crisis? A: "No, I don't think the IPCC is in crisis. We will resolve this issue about the timeline. I mean, we had a lot of big successes in Hangzhou... So IPCC is moving forward. "On the timeline issue overall, there were two options that are basically on the floor there. One for a timeline that is aligned with the second global stocktake under the Paris Agreement (due in 2028) and another one which is slower. "And for the countries that are proposing the slower timeline, there are another set of considerations. It's about the time that's available for countries to review the draft reports of IPCC and it's about the time that's available for people from developing countries to produce literature. "So we need to get to the issue at the next meeting of IPCC, which should take place in the last quarter of this year. And I'm optimistic we will get a solution there and move forward." Q: The United States was absent from the meeting in China. Are you concerned? A: "We don't normally comment on who's at a particular meeting until the reports come out. But, you know, it's been widely reported that the US didn't register for, or participate in, the meeting in Hangzhou, and that is indeed the case. "At every meeting we have 60 or 70 countries or members of IPCC that don't turn up for the meeting, don't register. The US was one of these at this meeting, and it was a business as usual meeting. We got the job done. We got the outlines of the reports agreed." Q: IPCC reports take five to seven years, which some say is far too long. Is the IPCC still relevant? A: "It's manifestly relevant. The 1.5 (degrees Celsius) report in the last cycle just had an absolutely huge impact, globally, in terms of negotiations. And if you go along to every Conference of the Parties, you will find every delegation standing up and saying, we have to rely on the science and refer back to IPCC reports. "So the absolute evidence there is that IPCC continues to be relevant. What we are not is a 24/7 news organisation because of these five to seven year cycles. We have a very elaborate process of review. It takes time to go through them. "But when we produce our reports, they have the stamp of authority of the scientists and consensus among governments, and that makes them very powerful. And I think if we compromise our procedures, we would lose that authority." Q: Global temperature records have been broken in recent years, surprising even some scientists. Is global warming greater than predicted in climate models? A: "There's a lot of intense scientific work going on at the moment to try and understand, precisely, what's happened over the last two to three years, and what explains things. "The understanding I have, from talking to scientists -- and just to say, I am not a physical climate scientist myself -- my understanding is that we are at the boundary of exceptional circumstances for the global indicators. But for particular regions and for example, for ecosystems, we are also well beyond the boundaries of the expected range. "So there's a lot of work going on to try and understand that at the moment... We hope there will be enough literature to provide a better explanation when IPCC next reports, probably 2028 for the Working Group (1) Physical Science report." jmi/np/yad

UN warns that ‘time is not on our side' as key climate science meeting begins
Representatives from nearly 200 countries gathered on Monday to work out the details of the next major UN climate science report. The Intergovernmental Panel on Climate Change (IPCC) is meeting for a week-long session in Hangzhou, China to negotiate the content and timing of the next landmark assessment. It comes not long after several climate agencies c onfirmed that 2024 was the hottest year on record. On Monday, UN Environment Programme chief Inger Andersen opened the meeting by warning that 'time is not on our side', urging 'ambitious' outcomes from these talks. IPCC Chair Jim Skea said it was a 'pivotal session' for the delivery of the next report on global climate science. What is the Intergovernmental Panel on Climate Change assessment report? These landmark reports from the IPCC were set up in 1988 to inform policymakers of the latest climate science. The first was published in 1990 and they are now considered to be the most authoritative source of global climate science information. In the words of World Meteorological Organisation deputy secretary general Ko Barret at the opening of the meeting on Monday, they are 'a guiding compass for governments as they navigate the complexities of climate change'. The report brings together and summarises the latest evidence on climate change from leading scientists around the world and takes hundreds of experts years to produce. This will be the seventh round of assessments that will compile global climate science into three reports: one on the physical science of climate change, one on the climate impacts, and one on solutions for reducing greenhouse gas emissions. The three-part report is currently set to be released in 2029 – but that could change as some countries call for an earlier delivery date. Why do countries disagree about the timing of the report? Discussions in Hangzhou are expected to be tense as it could be the last chance for countries to agree on a timeline. Some are pushing for the next report to be released earlier than planned. A group of 20 ministers from the High Ambition Coalition has called for the protection of climate science that countries rely on to make vital climate policy decisions. Environment ministers behind the statement include those from EU countries, island nations, and some of the countries most vulnerable to climate change. 'We owe it to everyone suffering the impacts of the climate crisis now, and to future generations, to make decisions about our planet's future on the basis of the best evidence and knowledge available to us,' they said in a joint statement. The ministers added that it is vital the IPCC's latest report is ready in time to inform the next UN Global Stocktake in 2028, a process that assesses the world's progress towards meeting Paris Agreement goals. A group of countries made up of Russia, Saudi Arabia, China, South Africa and India - backed by Kenya - has pushed back on an accelerated timeline, arguing that it would be too rushed. They have also said it could put the report's inclusivity at risk, making it harder to include scientists from the Global South. Has Trump prevented the US delegation from attending? US officials from the State Department and scientists from federal agencies have reportedly been pulled out of IPCC talks by the Trump administration. It comes after President Donald Trump signed an executive order to withdraw the US from the Paris Agreemen t for a second time on his first day in office. Sources familiar with the situation told news agencies Reuters and Axios that a stop work order was impacting staff at the US Global Change Research Program and the National Oceanic and Atmospheric Administration – key organisations that usually take part in IPCC talks. NASA's chief scientist Kate Calvin – who holds a leadership role in the new report cycle - will no longer attend as a result, according to CNN, which cited a spokesperson from the space agency. They said that this was part of Trump's broader withdrawal from multilateral cooperation and efforts to mitigate climate change.
