Why Earth is Warming

Energy from the sun heats the earth surface, warms the atmosphere and powers the ocean currents.Scientifically, records show that oceans are heated by 14×1018 Joules of energy.

Scientists measure oceans because they absorb the vast majority of the heat associated with global warming, and the earth’s temperature is dictated by ocean temperatures.
In fact, more than 90% of global warming heat ends up in the oceans with the fastest warming being the Atlantic, Indian and Northern Pacific oceans.
Even, they absorb more of the heating from human-carbon emissions, and temperature is not rising uniformly across the planet because the sun heats the equatorial tropics more than the polar regions.
Since the Industrial Revolution, human activities have released large amounts of carbon-dioxide and other greenhouse gases into the atmosphere, which has changed the earth’s climate.
And, for more than a hundred years, air temperature has been measured by weather observers all over the world.
Averaging these daily measurements over a whole year allows us to see the long-term trend instead of the short-term weather events.
Hence, the long-term trend is that: the earth is warming over time.
Moreover, the greenhouse gases that have mostly contributed to the earth warming include: carbon-dioxide, methane, nitrous oxide to mention but a few.
I hereby describe them,thus:
Carbon-dioxide, CO2
Carbon-dioxide mainly comes from burning organic materials; coal, oil, gas, wood and solid wastes. Atmospheric carbon-dioxide- the most dangerous, prevalent and the highest level greenhouse gas ever recorded; and has increased by more than 40% since pre-industrial times.
The carbon-dioxide gas absorbs solar energy and keep heat close to earth surface, rather than letting it escape into space.
And that trapping of heat is what we are known today as “greenhouse effect”. This is what keeps the earth habitable-otherwise, it would be too cold at night.
Methane, CH4
Methane concentration has been increased to more than 2.5times.Oil, gas and mining operations release large amount of methane- a potent greenhouse gas, either by accident or design.
Information gathered shows that global energy sector was responsible for nearly 135million tons of methane emissions in 2022, a slight rise from the in 2021.
Also, about 40% emissions attributed to human activity, second to agriculture.
Methane is responsible for about 30% of the rise in global temperature since the Industrial Revolution. Its rapid and sustained reductions are the key to limiting near-term global warming and improved air quality.
Nitrous oxide,N2O
Climate change, greenhouse gas emissions and warmer temperatures are changing nitrous oxide emissions.
Nitrous oxide, known as “laughing gas” is the most important greenhouse gas after carbon-dioxide and methane, and the biggest human-related threat to the ozone layer.
Though, it is rapidly increasing, mostly due to large-scale farming with synthetic fertilizers and cattle ranching.
Moreover, natural cycle and fluctuations has been a cause to the earth’s climate changing several times over the last 800years, and our era of global warming is directly attributed to human activities as afore-mentioned. In the US, the largest source of greenhouse gas emission is transportation, followed closely by electricity production and industrial activities. While in Nigeria the largest source of greenhouse gas emissions are waste and industrial pollutions.
Nevertheless, the impacts of global warming are felt by people everywhere in one way or the other, but are experienced most by the under-privileged, economically marginalized, and people of colour for whom climate change is often a key driver of poverty, displacement, hunger and social unrest.
Curbing these dangerous climate change requires very deep cut in emission as well as the use of alternatives to fossil fuels worldwide.
The good news is that countries around the globe have formerly committed as part of the 2015 Paris Climate Change Agreement to lower the emission by setting new standards and crafting new policies to meet or exceed those standards.But, the bad news is that we are not working fast enough.
To avoid the worst impacts of climate change, scientists tells us that we can reduce global carbon emission by as much as 40% by 2030, and for that to happen global communities must step up to decarbonize electricity generation by equitably transitioning from fossil fuel-based production to renewable energy sources like wind, solar and geothermal energy to mention but a few. Also, to electrify our automobiles; and to maximize energy efficiency in our building appliances and industries.
Projection from Earth System Modelshows that if we find ways to release fewer heat trapping gases into the air, global average temperature will increase about 10C to 1.50C (33.80F to 34.70F). And having adapt to changes resulting from a warmer world, our actions would help keep the earth a loveable place for all.

AI-Driven Memory Chip Fuels Global Phone Price Surge

Global technology markets are entering a new phase of strain as surging memory chip prices intensify the ongoing semiconductor shortage. For Nigeria, the ripple effects could translate into a 15 – 20 per cent increase in phone price levels if supply pressures persist into the next quarter.

While attention has largely focused on advanced AI processors, the sharpest escalation is occurring in memory chips, specifically DRAM (Dynamic Random Access Memory) and NAND (Flash Memory), which are essential to smartphones, PCs, and vehicles.
According to Bloomberg data, spot prices for DRAM have surged more than 600 percent in recent months. NAND prices have also climbed as artificial intelligence infrastructure expands global storage demand.
This shift reflects a structural realignment rather than a short-term disruption.
Massive AI infrastructure investments led by hyperscalers such as Amazon have redirected fabrication capacity toward high-bandwidth memory (HBM), a critical component for AI accelerators. This shift has tightened supply for conventional memory used in consumer devices.
Market analysts now describe the situation as a memory “supercycle,” breaking the industry’s traditional boom-and-bust pattern. Historically, memory cycles lasted three to four years. According to Jian Shi Cortesi of GAM Investment Management, the current cycle has already exceeded previous ones “both in length and magnitude,” with little evidence of demand momentum softening.
Financial markets reflect the divide. A Bloomberg gauge of global consumer electronics makers has fallen roughly 10 per cent since late September, while a basket of memory manufacturers has surged about 160 per cent over the same period. Shares of SK Hynix, a key high-bandwidth memory supplier to Nvidia, have climbed more than 150 per cent.
By contrast, downstream manufacturers reliant on affordable memory supplies are under pressure. Nintendo has warned of margin compression linked to shortages. Qualcomm shares declined after signaling memory constraints that could limit phone production. PC makers such as Lenovo and Dell have also retreated from recent peaks amid concerns that rising chip costs could dampen demand.
The divergence underscores a widening gap between component producers and device assemblers.
Memory is central to modern smartphone performance. Higher DRAM and NAND capacities power AI-enabled features, high-resolution imaging, and multitasking capabilities. Rising memory costs, therefore, feed directly into the bill of materials.
Even in a moderate demand environment, a constrained memory supply can limit production volumes. Qualcomm’s recent indication that memory shortages may restrict handset output highlights the risk of scarcity extending beyond price increases into availability challenges.
Compounding the issue, a foundry such as TSMC is prioritising higher-margin AI-related contracts at advanced nodes. Combined with the reallocation of capacity toward high-bandwidth memory, this limits flexibility in supplying traditional mobile processors and storage components.
For Nigeria, the likely outcome is not immediate widespread stockouts, but gradual upward revisions in retail pricing.
Nigeria’s electronics market remains heavily import-dependent, with minimal semiconductor manufacturing capacity. Retailers are therefore exposed to global cost shifts and supply volatility.
Distributors in major commercial hubs such as Lagos’ Computer Village are closely monitoring global trends. Some are securing inventory ahead of anticipated adjustments, while others are maintaining leaner procurement cycles to manage uncertainty.
Duration risk remains a key concern. Fidelity International’s Vivian Pai recently observed that while markets may be pricing in normalization within one to two quarters, industry tightness could persist through the rest of the year. If that proves accurate, manufacturers will have limited room to absorb higher component costs without passing them through to consumers.
Mid-tier smartphones, especially those balancing affordability with competitive performance, are likely to face the greatest pressure. Manufacturers may respond by offering lower base storage variants, delaying feature upgrades, or raising prices incrementally across product lines.
Parallel imports could increase if global scarcity intensifies, potentially raising concerns about warranty coverage and after-sales support.
Globally, firms are attempting to mitigate exposure by locking in long-term supply contracts, raising product prices, or redesigning devices to use less memory. However, semiconductor fabrication is capital-intensive and slow to scale. New fabrication plants require years to build, and expanding high-bandwidth memory output involves complex processes that cannot be rapidly accelerated.
For Nigeria, the episode underscores the importance of strengthening digital resilience. While domestic chip fabrication remains unlikely in the near term, expanding local device assembly, promoting repair ecosystems, and supporting component recycling could help cushion future supply shocks.
If projections hold, Nigerian buyers may begin seeing incremental price adjustments within weeks. Mid-range Android devices are likely to record the most noticeable changes, while premium models, already positioned at higher price points, may see more measured increases.
As it stands, AI’s explosive growth is reshaping semiconductor allocation patterns, and memory, once viewed as a product with prices that rise and fall in cycles, is behaving like a sustained constraint.
The widening gap between stock market winners and losers reflects the magnitude of this transition. As AI infrastructure spending accelerates globally, consumer electronics markets, including Nigeria’s, must adjust to a new cost environment.
Whether the squeeze proves temporary or evolves into a prolonged recalibration will depend on how quickly semiconductor capacity expands. For now, the trajectory suggests continued upward pressure on global electronics pricing, and Nigeria’s phone price expectations may have to adjust accordingly.

INTERPOL Arrests 651, Recovers $4.3m from Cybercrime in Nigeria, Others

African law enforcement agencies arrested 651 suspects and recovered over $4.3 million in a joint operation targeting investment fraud, mobile money scams, and fake loan applications.

As INTERPOL revealed on Wednesday, Operation Red Card 2.0 identified 1,247 victims between December 8 and January 30 while targeting cybercrime operations linked to over $45 million in financial losses.
Authorities across 16 countries also seized 2,341 devices and took down 1,442 malicious websites, domains, and servers during this joint action coordinated by the African Joint Operation against Cybercrime (AFJOC).
In Nigeria, police officers dismantled an investment fraud ring that was recruiting young people to run phishing, identity theft, and fake investment schemes, taking down over 1,000 fraudulent social media accounts in the process.
They also arrested six members of a Nigerian cybercrime gang that used stolen employee credentials to breach a major telecom provider.
Kenyan investigators also apprehended 27 suspects while investigating fraud networks that used social media and messaging platforms to lure victims into fake investment schemes.
In Côte d’Ivoire, 58 suspects were arrested as part of a crackdown on predatory mobile loan apps that targeted victims with hidden fees and abusive debt-collection practices.
“These organized cybercriminal syndicates inflict devastating financial and psychological harm on individuals, businesses and entire communities with their false promises,” said Neal Jetton, the head of INTERPOL’s Cybercrime Directorate.
“Operation Red Card highlights the importance of collaboration when combatting transnational cybercrime. I encourage all victims of cybercrime to reach out to law enforcement for help.”
One year ago, African law enforcement arrested another 306 suspects in the first stage of this INTERPOL-led operation targeting cross-border cybercriminal networks.
This is the latest INTERPOL operation targeting African cybercrime, with thousands of arrests and multiple multimillion-dollar operations disrupted or dismantled in recent years, following Operation Serengeti and Operation Africa Cyber Surge.
