Ocean-surface warming 4x faster in last four decades: Study

New Delhi, Jan 28: The rate of ocean warming has more than quadrupled over the past four decades, according to a new study on Tuesday, explaining why 2023 and early 2024 saw unprecedentedly high sea temperatures.
The study, published in the journal Environmental Research Letters, showed that ocean temperatures were rising at about 0.06 degrees Celsius per decade in the late 1980s. However, they are currently increasing at 0.27 degrees Celsius per decade.
“If the oceans were a bathtub of water, then in the 1980s, the hot tap was running slowly, warming up the water by just a fraction of a degree each decade. But now the hot tap is running much faster, and the warming has picked up speed,” said lead author Professor Chris Merchant, at the University of Reading, UK.
Merchant said that cutting global carbon emissions and moving towards net zero is the only way to slow down warming. In 2023 and early 2024, global ocean temperatures hit record highs for straight 450 days.
Besides El Nino, a natural warming event in the Pacific, the team found that the sea surface warming went up faster in the past 10 years than in earlier decades. The study noted that about 44 per cent of the record warmth was attributable to the oceans absorbing heat at an accelerating rate.
The findings show that the overall rate of global ocean warming observed over recent decades is not an accurate guide to what happens next: it is plausible that the ocean temperature increase seen over the past 40 years will be exceeded in just the next 20 years.
Because the surface oceans set the pace for global warming, this matters for the climate as a whole, the team explained.
This accelerating warming underscores the urgency of reducing fossil fuel burning to prevent even more rapid temperature increases in the future and to begin to stabilise the climate.
Warming ocean temperatures can increase the spread of diseases in marine species. This in turn can affect humans, when consuming marine species, or from infections of wounds exposed in marine environments.

India on track to become $5 trillion economy in next 3 years: Piyush Goyal

New Delhi, June 25: India is well on track to achieve a $5 trillion economy and the expectation is to reach this milestone within the next three years, Commerce and Industry Minister Piyush Goyal has stressed.
By 2027, “we hope to become the third largest economy in the world,” he said, adding that all stakeholders — government, business community, industry, trade, and 140 crore Indians — are deeply aligned with the Prime Minister’s vision for ‘Viksit Bharat 2047’.
The minister stated that the government, under Prime Minister Narendra Modi, has focused on quantum change, not incremental progress and it focused not only on growth, but on inclusive, sustainable and honest growth.
He was speaking at a webinar hosted by the Merchants’ Chamber of Commerce and Industry (MCCI) on ‘India’s March Towards a $5 Trillion Economy: Navigating Global Challenges’.
On India’s economic strength, Goyal stated that the country has moved from being part of the fragile five to becoming one of the top five economies in the world.
“We have a strong macroeconomic foundation. Our banking system is strong and robust, with high ability to lend. Our inflation is among the lowest India has ever seen — down to 3 per cent again,” he said.
The minister further said that the government has focused on achieving growth that is calibrated for the Indian story and that believes in ‘Seva, Sushasan and Navachar; — Service, Good Governance and Innovation.
He highlighted that MCCI will continue to play a very important role during Amrit Kaal in achieving this goal. Such dialogues help the government better understand what needs to be done to support industries, even in the face of global volatility, turbulence, and uncertainty.
“History reminds us that great economies are not built in calm waters. Great economies are built in turbulent seas,” Goyal emphasised, adding that this is India’s time to seize the moment and that the opportunity must not be missed.
He praised MCCI’s 124-year journey, calling it a bridge between the government, stakeholders, and industries. “MCCI can be called as Mobilizing Commerce and Connecting Industries, because that is exactly what MCCI does,” Goyal added.

Indian stock market shrugs off midweek volatility, ends week on robust note

Mumbai, June 21: The Indian equity benchmarks wrapped up the session on a robust note last week, decisively breaking through critical resistance level, propelled by sustained institutional accumulation, analysts said on Saturday.
The Nifty 50 convincingly closed above the psychologically significant 25,000 mark on Friday, underscoring bullish momentum. At the closing bell, the Sensex rallied 1,046.30 points, or 1.29 per cent, to settle at a fresh high of 82,408.17, while the Nifty 50 advanced 319.15 points, or 1.29 per cent, to end at 25,112.40.
“Relentless inflows from institutional investors — both Foreign Institutional Investors (FIIs) and Domestic Institutional Investors (DIIs)—acted as key tailwinds, offsetting headwinds from prevailing geopolitical uncertainties and reinforcing positive sentiment across the street,” according to a note by Bajaj Broking Research.
Nifty Index formed a sizable bull candle with a higher high and higher low signaling resumption of up move after recent corrective consolidation. The index in the process closed firmly above the 25,000 levels signalling strength.
“Going forward, we anticipate the index to retest the upper boundary of the recent five-week consolidation zone, currently pegged near the 25,200 mark. A decisive breakout above this resistance band could open the door for an upward extension towards the 25,500 zone in the near term,” said the note.
The Indian stock market shrugged off midweek volatility triggered by escalating tensions in the Middle East and a sharp spike in crude oil prices.
The Reserve Bank of India’s relaxation of project financing norms provided a boost to financial stocks.
“The RBI’s continued dovish tone — signalling potential rate cuts on validating subdued inflation — further reinforced market confidence, positioning monetary policy as a key stabilizing force amid global uncertainty,” said Vinod Nair, Head of Research, Geojit Investments Ltd.
Crude prices surged early in the week due to geopolitical unrest, sparking concerns over inflation. However, the pace of growth in oil prices tapered significantly after the initial spike, helping to ease fears of a sustained inflationary rebound.
Investor sentiment toward the pharmaceutical sector has turned cautious following the proposed imposition of new tariffs, said analysts.
With the deadline for a 90-day pause on reciprocal tariffs approaching, markets are closely tracking trade negotiations and deal-making activity expected to unfold over the next two weeks.
“Meanwhile, geopolitical uncertainty continues to loom, as statements from world leaders regarding possible military involvement in the Middle East keep markets on edge. Investors will also keep a close eye on upcoming U.S. GDP and PCE data, along with India’s PMI figures, for cues on the strength and direction of economic recovery at home and abroad,” Nair noted.

Stock market exhibits resilience, RBI’s rate cut icing on the cake

Mumbai, June 7: After starting the week with consolidation, the domestic market exhibited resilience amid concerns over tariff wars and geopolitical escalations, analysts said on Saturday.
Markets consolidated for the third consecutive week but managed to end higher by nearly a per cent, buoyed by favourable domestic cues.
After remaining range-bound for most of the week, benchmark indices surged sharply on Friday and settled near the week’s high, with the Nifty closing at 25,003 and the Sensex at 82,118.99.
“The highlight of the week was the RBI’s policy announcement, which took the market by surprise. The central bank implemented a sharper-than-expected 50 bps repo rate cut and a 100 bps CRR reduction, signalling a strong pro-growth stance. Notably, the policy stance was also shifted from ‘accommodative’ to ‘neutral’ — a move that came sooner than expected,” said Ajit Mishra, SVP, Research, Religare Broking Ltd.
By front-loading its easing measures, the RBI has underscored its commitment to reviving domestic growth amid global uncertainties. While such a bold approach was expected to unfold gradually, this decisive action reinforces confidence in the central bank’s intent to support economic recovery while managing inflation risks.
This week, sectoral performance was broadly positive, with rate-sensitive sectors witnessing strong buying interest. Realty, auto, and banking stocks led the rally, reflecting improved outlooks for credit growth and consumer sentiment. Financials and NBFCs also gained, as lower interest rates are expected to enhance borrowing conditions.
Conversely, IT stocks underperformed due to persistent global uncertainties, particularly in the U.S. and European markets. In the broader markets, both midcap and smallcap indices outperformed the benchmarks, reflecting a risk-on sentiment among investors, with gains ranging between 2.8 per cent and 4 per cent.
According to Vinod Nair, Head of Research, Geojit Investments Ltd, bolstered by supportive macro indicators such as strong Q4 GDP, GST collection and a favourable monsoon, investors focused on domestically oriented and interest-sensitive sectors such as financials, real estate, retail and FMCG, which saw strength, supported by strong institutional inflows.
Profit booking was visible during the week on account of the ongoing global uncertainty. Mid and small caps generally outperformed large caps, driven by better earnings and valuations.
“While China’s rare earth restrictions pose long-term risks and investors await the inflation print in the US, the aggressive RBI rate cut, backed by cooling inflation and a steady GDP outlook, is likely to support investor confidence amidst the ongoing global uncertainties,” Nair noted.
Going forward, market participants will focus on key macroeconomic data for further cues. High-frequency indicators such as CPI inflation will be closely tracked to gauge demand trends and the central bank’s next steps, said experts.
