UN Body Says Hottest Year Record Will Be Topped Again By 2029
The World Meteorological Organization on Wednesday released a report that projects global temperatures will remain near record levels over the next five years, with a strong chance the 2024 annual temperature record will be broken during this period, likely worsening the impact of climate change and increasing the chances of extreme weather events.
The WMO released its annual decadal climate update report on Wednesday, with updated projections for the years 2025 to 2029, which projects an 80% chance of one of the next five years breaking 2024's record as the hottest year ever.
The report predicts that there is an 86% chance that average global temperatures will be more than 1.5 degrees Celsius above the 1850-1900 pre-industrial levels in at least one of the next five years.
There is also a 70% chance that the 5-year average temperature for 2025-2029 will be more than 1.5 degrees Celsius above pre-industrial numbers—a key benchmark laid out in the Paris Climate Agreement.
The U.K. Meteorological Office, which produced the report for the WMO, also warned that for the first time, there was a very slight possibility (1%) of average temperatures exceeding pre-industrial levels by 2 degrees in one of the next five years.
The report also projected that the Arctic region will continue to warm at a rate that is 3.5 times higher than the rest of the world, which could lead to a rapid melting of ice caps and a rise in sea levels.
The 1.5 degrees Celsius or 2.7 degrees Fahrenheit increase over the pre-industrial average is a critical threshold under the 2015 Paris Climate Agreement. The agreement's signatories have set this as the preferred limit for the increase in global temperatures they want to work towards, with a 2 degrees Celsius being set as the maximum upper limit. If the latest WMO report projections are correct, it does not necessarily represent a breach of the Paris Agreement limit, as that takes into account the average levels over two decades. Nonetheless, the threshold being breached multiple times this decade is likely to trigger alarm among climate scientists.
'We have just experienced the ten warmest years on record. Unfortunately, this WMO report provides no sign of respite over the coming years, and this means that there will be a growing negative impact on our economies, our daily lives, our ecosystems and our planet,' WMO Deputy Secretary-General Ko Barrett said.

US Coast Guard unveils first polar icebreaker in more than 25 years
PASCAGOULA, Miss. - The U.S. Coast Guard's newest polar icebreaker is officially operational, which the agency says will bolster its Arctic operations. The 360-foot-long icebreaker departed from its assembly port in Pascagoula, Mississippi and was headed to Seattle, where it will be based until renovations are completed at its homeport in Juneau, Alaska. Icebreakers clear passages through icy waterways in both the Arctic and Antarctic, and are known to aid in search and rescue missions as well as support scientific research operations. Similar-sized ships are known to break up ice that is upwards of 21 feet thick, due to their reinforced hulls and bows, with engines capable of producing a significant amount of horsepower. "The vessel is manned with a hybrid crew consisting of military cuttermen and civilian mariners. This is the second vessel in Coast Guard history to bear the name Storis. The original Storis, known as the 'Galloping Ghost of the Alaskan Coast,' had a storied history conducting 64 years of icebreaking operations in Alaska and the Arctic before being decommissioned in 2007," the agency said in a statement. Antarctica's 'Doomsday Glacier' Is Melting Away Differently Than Scientists First Thought The USCGC Storis will join the USCGC Polar Star and the USCGC Healy as part of the Polar Security Cutter Program. Both of the other icebreakers have faced challenges due to their age, with the Healy recently experiencing a significant fire, while the 50-year-old Polar Star was taken out of service for necessary repairs. "Our national security interests in the Arctic have also never been more critical, demonstrated by the joint Russian and Chinese naval and air task forces that have operated off Alaska's coastline these past two years. Since coming to the Senate, I've been working relentlessly to wake up our federal government to the strategic importance of this region," Alaska Senator Dan Sullivan previously said in a statement. World's Largest Iceberg On Possible Collision Course With Island In South Atlantic Ocean The Coast Guard says its fleet of large icebreakers must double or even triple in size to meet growing operational demands. "Russia has 55 icebreakers and is in the process of building more. By 2025, China, which has no sovereignty over any Arctic waters, is set to surpass the United States' icebreaker fleet. The Alaska congressional delegation has long since recognized this as a competitive disadvantage in the Arctic and advocated for additional resources to bolster the USCG icebreaker fleet," Alaskan legislators previously stated. The newly acquired vessel is expected to support missions later in the year, although a specific deployment schedule was not article source: US Coast Guard unveils first polar icebreaker in more than 25 years

Are these the best American stocks for my ISA?
At the moment, US-listed stocks account for also exactly half of my ISA holdings. To be precise, around 42% of my Stocks and Shares ISA is in cash — I'm a little wary at the moment — and 29% in both international (all North American) and UK-listed stocks. So, why am I a little wary? Well, I'm being more selective about US stocks because the sharp rise in tariffs this year has fundamentally changed the investment landscape. Between January and April 2025, the average effective US tariff rate soared from 2.5% to 27%. These are levels not seen in over a century. It had settled slightly at 17.8% in May, but negotiations are ongoing. Such high tariffs are likely to be raising input costs, squeezing corporate profit margins, and dampening earnings growth. I'm focusing on the metrics because, in today's environment, growth alone isn't enough—valuations must be justifiable. With the S&P 500's forward price-to-earnings (P/E) ratio at 21.3 — above both 5- and 10-year averages — it's crucial to find companies where earnings multiples make sense relative to their growth prospects. As always I'm prioritising growth-adjusted ratios like the P/E-to-growth (PEG) ratio, which help identify stocks offering genuine value for their expected growth, but being even more selective than usual. So, who are they? Well, Pinterest (NYSE:PINS) stands out as fundamentally cheap by most metrics, while Alphabet (NASDAQ:GOOGL) trades at lower multiples than its peers despite similar growth trajectories. In my view, this makes both attractive, non-speculative picks in a market where speculation is increasingly risky. Pinterest currently trades at a forward P/E of 17.7 times and a PEG ratio of 0.53, reflecting strong expected earnings growth at a reasonable valuation. The company's AI-powered ad tools and a growing international user base have driven double-digit revenue growth, with Q1 2025 revenue up 16% year on year and global monthly active users reaching 570m. Despite these strengths, Pinterest remains heavily dependent on digital advertising, making it sensitive to shifts in advertiser budgets and broader economic cycles. It's also very geographically reliant on North America for revenues, and this represents a risk as well as an opportunity. The region represents less than one-fifth of total users but nearly 80% of sales. However, there's plenty to be positive about. Al really seems to be a game changer, and has contributed to the company's improving profitability and attractive growth profile. Alphabet trades at a forward P/E of 17.3 times. That's above the communications sector median of 13.6 but about 30% below its own five-year average, signalling a more attractive entry point relative to its history. The PEG ratio stands at 1.16, lower than the sector's 1.43, indicating solid expected earnings growth for its valuation. I'd also add that Alphabet is more than just a communications stock, which makes its valuation so attractive. Recent performance has been strong. In Q1 2025, Alphabet reported 12% revenue growth to $90.2bn, with Google Cloud up 28% and operating margin expanding to 34%. Risks? There are always risks even with some of the largest companies in the world. One here is Alphabet potentially being forced to divest Chrome in an anti-trust trial. However, for me, its wide economic moat and diversified growth engines underpin long-term appeal. I've recently bought both these stocks.

Reform declares war on all gold-plated public sector pensions
A Reform UK government would radically overhaul gold-plated public sector pensions to stop them bankrupting Britain. Richard Tice told The Telegraph he would put everything on the table and end the taxpayer 'rip off' if his party won the next general election. Reform's deputy leader said the party would consider moving all public sector employees out of their 'Rolls-Royce' pension plans and into the defined contribution schemes almost all private sector workers have. Britain currently hands £54bn a year to public sector retirees and another £35bn in pension contributions to current state workers, with both groups entitled to guaranteed, inflation-linked payments for life. It comes after Reform pledged to axe defined benefit council pensions, which a recent Telegraph investigation revealed now costs some local authorities more than half of what they raise in council tax. Britain currently has more than three million public sector pensioners, the vast majority of whom are retired NHS workers, teachers, civil servants and members of the armed forces. Their schemes are all unfunded, meaning the contributions that come in from employers and employees are immediately used to pay current retirees, rather than being prudently invested to pay future pensions. However, contributions have fallen short of the amounts paid out, with taxpayers funding a £49bn shortfall over the past decade alone. Historically, they also haven't covered the cost of new pension rights built up by current workers. John Ralfe, a pensions consultant, calculated that the shortfall between contributions and future pensions was £208bn between 2013-23 – and it will be met by current and future taxpayers. The system, which would be illegal in the private sector, has built up pension liabilities running into the trillions. Speaking to The Telegraph, Mr Tice said action was needed where successive governments had failed. He said: 'We've got to have these conversations over the next few years and wake people up as to why we're in such a financial mess. Public sector pay and benefits have soared and yet productivity has collapsed, and it's a catastrophe. 'I want to be honest with the country. I want to say, 'if we don't sort this out, this will be a major factor in the country going bankrupt'. It's that serious.' He also confirmed that Reform would consider moving every public sector worker into the type of defined contribution schemes that almost all private sector workers are members of. He added: 'Everything has got to be on the table. The old rule was that public pay was less than the private sector because they had a more generous pension scheme, but successive governments have lifted pay in the public sector and therefore the old deal is no longer valid. 'Bluntly, there's been a failure to be honest about this. The public sector has pulled the wool over the eyes of the taxpayer. We're going to talk about it for the next four years: that taxpayers are being ripped off and it can't go on.' Last week, Mr Tice said that Reform-controlled councils would stop offering the generous pension scheme to new employees and reduce pay rises for existing workers to balance out the cost of funding their retirements. The Local Government Pension Scheme, the largest funded scheme in the UK, already spends £15bn a year on paying pensions across Britain. A recent Telegraph investigation uncovered five local authorities that stuff more than half of their council tax into staff pension pots. Another 19 fork out more than a third, while 60 spend more than a fifth on funding the generous schemes. It came after a series of Telegraph revelations about the cost of public sector pensions. Last year, we calculated that Britain's current bill was £4.9 trillion, with each household on the hook for £173,000. In October, we reported that another £20bn would be added to taxpayer-funded pension payouts after they rose another 1.7pc following September's inflation figure. Last month, we showed how the latest public sector pay rise would cost another £1bn in pension contributions alone. We also revealed how taxpayers have been handed extra pension bills of £45bn for Royal Mail, £1.7bn for the Environment Agency and more than £300m for retired train drivers. Switching public sector workers to defined contribution pensions could send the taxpayer's annual bill plummeting to around £4.5bn, saving almost £28bn a year, calculations have shown. However, Barry McKay, of pensions firm Barnett Waddingham, warned it would be difficult to make the change. He said: 'If you move to defined contribution, those contributions paid by existing workers would go into a pot somewhere to be invested and grow for the benefit of each worker, but in doing so there would be no money coming in to pay existing pensions. 'The Treasury would have to find a huge amount of money to pay the existing pensioners from somewhere else, because they don't have the contribution income any more. That leaves a massive hole in the Treasury accounts.' He added: 'There is a problem that we're effectively stuck with defined benefit.' Neil Record, a pensions expert and former Bank of England economist, said: 'The only practical solution to public sector pensions' increasingly intolerable burden on taxpayers is for the Government to offer a cash alternative, as an option, to all public sector employees. 'My guess is that in return for an approximately 30pc pay rise, most public sector employees would choose to give up accruing new pension rights as long as their existing rights were fully honoured.'
