A Time When We Count Plastic Waves on the Shore
It’s easy to overlook the plastic waste scattered on our beaches or floating in the ocean. But the reality is clear: plastic pollution is suffocating our oceans and destroying marine life
What does the reality of our oceans look like today? Plastic pollution. Do we go to the beach without ever noticing a plastic bottle or plastic waste amidst the beauty of the waves and the vast sea? Or have we lost sight of nature’s true state, consumed by the exploitation we have allowed? It’s time we took a moment to reflect.
Today, one of the biggest challenges facing our oceans is plastic pollution. Since 2018, the world has produced 359 million metric tons of plastic. According to the United Nations Environment Programme (UNEP), approximately 400 million tons of plastic waste are generated annually, with around 36% used for packaging—much of which ends up in landfills. In India alone, around 3.3 million metric tons of plastic waste is generated each year. And a large portion of this, approximately 8 million metric tons, ends up in the oceans annually.
Currently, our oceans are home to about 5.25 trillion plastic items, weighing a staggering 268,940 tons. By 2050, it is projected that there will be more plastic in the oceans than fish, according to a 2016 report presented at the World Economic Forum.
Disaster in the Deep Blue
Why is plastic waste so widespread in our oceans? As we walk along the beach, enjoying the beauty of the waves and the endless blue horizon, have we ever stopped to think about the plastic we might be overlooking? Beneath the surface, our oceans now hold vast quantities of plastic waste that are invisible to the naked eye, often carried by rivers or discarded carelessly by humans.
The plastic waste that litters the oceans consists of both macroplastics (larger objects such as bags and bottles) and microplastics (tiny particles that result from the breakdown of larger plastics). These microplastics, often less than 5 millimeters in size, are created as a result of exposure to sunlight, wave action, and other environmental factors. Even though these particles become so small, they do not disappear completely from the marine ecosystem.
Plastic waste, whether it’s a discarded plastic bottle, fishing gear, or other synthetic materials, poses a major threat to marine life. Marine creatures consume plastic debris, mistaking it for food, and suffer from serious health consequences. The damage is not limited to marine organisms; human beings are also at risk, as the toxic chemicals in plastics enter the food chain.
The Ecological and Economic Impact
The consequences of plastic pollution are far-reaching. For marine ecosystems, plastics lead to habitat destruction, toxic contamination, and loss of biodiversity. For humans, plastic waste affects fisheries, tourism, and coastal economies. Plastic waste also disrupts the functioning of marine ecosystems, which are essential for regulating the climate and providing food and oxygen for life on Earth.
Plastic debris floating on the water’s surface or sinking to the ocean floor threatens marine navigation and ship safety as well. The potential for harm is vast, and addressing the problem is crucial to preserving the future of our oceans.
Why Are We Still Struggling to Tackle Ocean Pollution?
Even as millions of tons of plastic waste flow into the oceans every year, why is there still no effective response to this environmental crisis? One reason is the lack of comprehensive research and detailed studies on the extent of microplastic pollution and its long-term impact on marine ecosystems. To understand the scale of the problem, we need to know how much waste is accumulating in the oceans and where the most significant concentrations are.
While commercial vessels and research ships have gathered some data, using plankton nets to collect ocean samples, this method only covers a small fraction of the vast oceans. The challenge is that the sheer size of the oceans makes it nearly impossible to assess the full scale of plastic pollution using current techniques. Moreover, long-term data on how plastic waste is changing over time is still limited.
The Impact of Plastic on Marine Life and Human Health
The effects of plastic pollution on marine life are devastating. Fish, birds, and other marine creatures often mistake plastic debris for food, leading to ingestion, which can be fatal. Some animals become entangled in fishing nets or plastic packaging, restricting their movement and leading to death. Even more concerning is the potential for toxic chemicals from plastics to enter the food chain, eventually reaching humans.
Moreover, plastic waste that floats on the surface or sinks to the bottom of the ocean poses a threat to navigation and shipping, making it difficult for vessels to safely navigate through affected areas. As plastics degrade over time, they release harmful chemicals into the water, further exacerbating the environmental damage.
Using Satellites to Track Plastic Waste
Understanding the extent and movement of plastic waste in the oceans is key to mitigating its impacts. Researchers at the University of Michigan once proposed an innovative solution by leveraging satellite data to monitor plastic pollution. NASA’s Cyclone Global Navigation Satellite System (CYGNSS), launched in 2016, has been used to track microplastics in the ocean, helping scientists better understand their location and movement. The research conducted by the University of Michigan on using NASA’s satellite data to monitor and track plastic waste in the oceans was published in 2020.
This method utilizes radar to measure surface roughness, which can indicate the presence of plastic debris. Since microplastics tend to float on the ocean surface and are influenced by wind patterns, this system can help identify areas with high concentrations of plastics, allowing for more effective cleanup efforts.
Satellites that record wind speed can also detect changes in the distribution of microplastics. Through satellite imagery, researchers have observed that plastic pollution in the northern hemisphere’s oceans peaks during the summer months, while in the southern hemisphere, it rises during January and February. This data offers critical insights into seasonal changes in plastic distribution and can guide future cleanup operations.
Researchers have also used satellite data to monitor pollution flowing from rivers, such as those in China’s Yangtze River, and how it affects nearby ocean regions. This type of research can be crucial in understanding how industrial growth and population density contribute to increasing plastic waste.
Satellite Data for Cleanup Efforts
One of the key benefits of satellite-based research is its potential to aid ocean cleanup organizations. By identifying areas with high concentrations of plastic, cleanup operations can be more focused and efficient. These organizations can deploy specialized vessels equipped to collect and recycle plastic debris, significantly reducing waste in targeted regions.
However, the relationship between ocean surface roughness and microplastic concentrations is still under study. While the researchers have observed a pattern, they caution that the link may not always be direct. Other factors, such as surfactants in the water, could also be influencing surface conditions, so more research is needed.
The use of satellite-based systems like CYGNSS is still a developing area of study, and researchers are continuing to improve the accuracy of detecting microplastics and understanding the seasonal variations of their distribution
As of now, the research has shown promising results, but the methodology is still under refinement. The findings have been used to create maps identifying regions with high levels of microplastics. These maps are helping organizations and cleanup efforts focus their resources more efficiently.The use of satellite-based systems like CYGNSS is still a developing area of study, and researchers are continuing to improve the accuracy of detecting microplastics and understanding the seasonal variations of their distribution. Researchers are also working on refining cleanup technologies based on this satellite data to increase their effectiveness in addressing plastic pollution.
Time to Address Ocean Pollution
Plastic pollution is a growing threat, and the time to act is now. Governments, industries, and individuals all have a role to play in reducing plastic waste and preventing further harm to our oceans. Stronger regulations on plastic production and disposal, increased public awareness, and innovation in biodegradable materials are all part of the solution.
As we continue to confront this crisis, it is essential that we understand the full extent of plastic pollution in our oceans, track its impact on marine ecosystems, and work toward sustainable solutions that protect the environment for future generations. The health of our oceans is directly tied to the health of our planet—and it is up to all of us to make a difference.
It’s easy to overlook the plastic waste scattered on our beaches or floating in the ocean. But the reality is clear: plastic pollution is suffocating our oceans and destroying marine life. As we continue to pollute, we risk not only the health of our oceans but also the survival of countless species, including our own. It is time to take action before the waves of plastic drown the beauty of the seas we cherish.
COP30
Over 832,000 Lives Lost, $4.5 Trillion in Damages, Extreme Weather The “New Normal”: Warns Climate Risk Index
A new report reveals the staggering toll of extreme weather — over 832,000 deaths and $4.5 trillion in losses between 1995 and 2024.
The numbers are stark, and the story they tell is even starker. More than 832,000 people have lost their lives and USD 4.5 trillion in direct economic losses have been recorded worldwide as a result of nearly 9,700 extreme weather events over the past three decades. That is the central finding of the Climate Risk Index (CRI) 2026, released by the environmental think tank Germanwatch at COP30 in Belém, Brazil.
The new report — the most comprehensive edition of the CRI to date — presents what its authors describe as a “mirror to global injustice”: a world where the poorest nations, least responsible for greenhouse gas emissions, continue to suffer the greatest losses.
Global South at the epicentre
According to the analysis, around 40% of the world’s population — more than three billion people — live in the eleven countries most affected by extreme weather events since 1995. These include India (ranked 9th), China (11th), Haiti (5th), and the Philippines (7th) — all nations of the Global South. None of these countries belong to the world’s richest economies, yet they bear the heaviest brunt of climate shocks.
“Heat waves and storms pose the greatest threat to human life when it comes to extreme weather events,” said Laura Schäfer, one of the index’s lead authors, in a statement. “Storms also caused by far the greatest monetary damage, while floods were responsible for the greatest number of people affected.”
In the 30-year period covered, storms alone caused over USD 2.64 trillion in damages, while floods accounted for nearly half of all people affected by disasters. Floods, storms, heat waves, and droughts together formed the deadly quartet responsible for most of the losses — both human and economic.
A decade of unrelenting disasters
From hurricanes that erased Caribbean islands to floods that swept away entire cities, the CRI 2026 paints a grim global mosaic.
At the top of the long-term index is Dominica, a tiny Caribbean island nation that has faced multiple catastrophic hurricanes. In 2017, Hurricane Maria alone caused losses amounting to three times the country’s GDP.
Myanmar ranks second, largely due to Cyclone Nargis (2008), which killed nearly 140,000 people and left deep scars still visible today. Honduras, Libya, Haiti, and Grenada follow, all of which endured either singularly devastating or repeated disasters.
The report notes that countries like Haiti, the Philippines, and India are trapped in cycles of destruction and recovery. “They are hit by floods, heat waves, or storms so regularly that entire regions can hardly recover from one disaster before the next strikes,” explained Vera Künzel, co-author of the index.
India among the top ten
India’s inclusion in the top ten highlights the scale and variety of climate hazards the country faces. Between 1995 and 2024, India endured over 430 major extreme weather events, resulting in more than 80,000 deaths, affecting 1.3 billion people, and inflicting USD 170 billion in damages (inflation-adjusted).
Recurring heat waves, increasingly intense monsoons, and devastating cyclones — from Odisha (1999) to Amphan (2020) — have made India one of the world’s most climate-vulnerable economies. Urban flooding in states like Maharashtra and Gujarat, and glacier-related floods in the Himalayas, have further underscored this fragility.
Even the rich are not spared
While the Global South remains most exposed, the new index shows that climate risks are no longer confined by wealth or borders. The United States (ranked 18th) and European nations such as France (12th) and Italy (16th) appear among the top 30 most affected countries — a reminder that the climate crisis has become universal.
“COP30 must find effective ways to close the global ambition gap”
The authors warn that no country is immune from the accelerating impacts of global warming. The year 2024 was the hottest on record, with global temperatures surpassing 1.5°C above pre-industrial levels for the first time. Scientists estimate that human-caused climate change added 41 extra days of dangerous heat for billions of people last year alone.
“The CRI 2026 results clearly demonstrate that COP30 must find effective ways to close the global ambition gap,” said David Eckstein, another co-author. “Global emissions have to be reduced immediately; otherwise, there is a risk of a rising number of deaths and economic disaster worldwide.”
A call for climate justice
The report urges the world’s wealthier nations to deliver on their long-standing promises of climate finance and loss-and-damage support for developing countries. Despite repeated commitments, funding for adaptation and disaster recovery remains far short of what vulnerable nations need.
Germanwatch estimates that developing countries may require up to USD 1.7 trillion annually by 2050 to address loss and damage caused by climate impacts. Without this support, the gap between rich and poor in climate resilience will only widen.
The CRI 2026 also points to positive developments — notably, a recent International Court of Justice advisory opinion affirming states’ legal duty to prevent and address climate harm, including through finance and reparations. The ruling, the authors note, adds legal and moral weight to the demands for urgent global action.
A warning — and a choice
Ultimately, the report is more than a statistical document; it is a warning. The patterns of destruction it reveals — from hurricanes in the Caribbean to heat waves in Asia — are not anomalies but signs of a “new normal.”
As COP30 negotiators gather in Belém, the message from the data is clear: unless emissions fall sharply and adaptation accelerates, the toll in both human lives and economic costs will keep rising.
“In a warmer world, tropical cyclones are becoming more intense and more destructive,” said Lina Adil, co-author of the index. “Without sustained global support, some nations will face challenges that are simply insurmountable.”

Brazil Cuts Emissions by 17% in 2024—Biggest Drop in 16 Years, Yet Paris Target Out of Reach
Brazil’s 2024 emissions dropped 16.7% to 2.15 GtCO₂e, led by Amazon deforestation control—the biggest annual fall since 2009—but the country still risks missing its Paris climate goals.
Brazil’s groEmissionsss greenhouse gas emissions fell from 2.576 billion tons of CO₂ equivalent in 2023 to 2.145 billion tons in 2024, the lowest drop since the country’s 17.2% decline in 2009. This turnaround was powered by enforcement against illegal deforestation, reversing a period of lax protections between 2019 and 2022. The net emissions figure—which deducts carbon absorbed by secondary forests and protected areas—dropped even further, down 22% year-on-year, landing at 1.489 billion tons in 2024.
Sectoral Breakdown: Where Emissions Fell and Rose
The land-use sector, mostly deforestation, saw its gross emissions tumble from 1.341 to 0.906 billion tons (32.5% drop)—the largest reduction on record for any sector. This shifted the national emissions profile:
>> Land use change: 42% in 2024, compared to 52% in 2023
>> Agriculture: 29%, up from 24%
>> Energy: 20%, up from 16%
>> Waste: 5%
>> Industrial processes: 4% (both stable)
Emissions in agriculture and energy remained mostly flat, with only waste (up 3.6%) and industry (up 2.8%) recording notable increases.
Deforestation Down, but Not the Whole Story
Enhanced government actions led to a 33% decline in Amazon deforestation emissions and a 41% drop in the Cerrado. Nevertheless, fires not associated with deforestation nearly doubled Brazil’s net deforestation emissions—an emerging risk as climate change fuels extreme drought and wildfires across formerly resilient biomes.
Agriculture, Cattle, and Energy: Stubborn Sources
Brazil’s cattle sector remains the single largest emissions source, responsible for roughly 51% of national total. Efforts to control methane—including increased feedlot use and smaller herds—delivered a marginal 0.2% reduction in herd size and a slight drop in emissions. Nitrous oxide from fertilizers and lime also saw small declines, offsetting overall emission growth. Notably, emissions from energy rose nearly 1% due to record travel and electricity demand; only record ethanol and biodiesel consumption kept fossil CO₂ in check.
Paris Pledge Still Out of Sight
Despite the historic emissions drop, Brazil is projected to end 2025 with net emissions of 1.44 billion tons—9% above its target under the Paris Agreement of 1.32 billion tons. While deforestation is falling, rising emissions from energy, agriculture, waste, and industry threaten to undermine overall climate progress. Experts emphasize that broader emission cuts, especially in fossil energy, are urgently needed for Brazil to have a chance at meeting its 2030 target (1.2 billion tons).
Brazil’s 2024 emissions breakthrough underscores the pivotal impact of deforestation control on the country’s climate footprint. Yet, absent deeper reforms in agriculture, waste, and especially energy, Brazil’s Paris goals may remain out of reach—a clear signal for policymakers ahead of COP30.

India and China to Peak Coal Emissions by 2030 — and India’s Data Proves It’s Economically Inevitable
New analysis finds China, India, and Indonesia—the world’s top coal users—can peak power-sector emissions by 2030, marking a global climate turning point.
In what could mark a historic global energy shift, new analysis from the Centre for Research on Energy and Clean Air (CREA) reveals that the world’s three largest coal growth markets, China, India, and Indonesia, are on track to peak their power sector emissions by 2030. Together, these nations accounted for a staggering 73% of global coal consumption in 2024, making this potential turnaround a defining moment in the fight against climate change
China: Clean Energy Outpaces Demand
China has already reached a milestone that once seemed improbable: clean energy growth has outpaced the rise in electricity demand, leading to a fall in coal power emissions since early 2024
In 2024 alone, the country added 277 GW of solar capacity and 80 GW of wind, with an additional 212 GW of solar in just the first half of 2025. “Since I announced China’s goals for carbon peaking and carbon neutrality five years ago, China has built the world’s largest and fastest-growing renewable energy system,” President Xi Jinping declared earlier this year.
If current trends continue, China’s coal use may never return to previous highs. But sustaining this progress depends on meeting its 2035 clean energy targets and avoiding a slowdown in installations.
“China has already added enough new clean electricity generation to cover all new demand growth, and power sector coal use and emissions have been falling since 2024 as a result,” said Lauri Myllyvirta, CREA’s Lead Analyst, in the report.
India: Rapid Clean Energy Expansion Takes Off
India’s clean electricity boom, once stalled, has roared to life. In 2024, the country added a record 29 GW of non-fossil capacity, and by mid-2025, that pace had surged by 69% year-on-year.
With Prime Minister Narendra Modi’s 500 GW clean power target by 2030, India is already more than halfway there. The nation’s growing domestic solar manufacturing base—118 GW of module capacity and 27 GW of solar cells—is transforming it into a global solar hub.
“Meeting India’s 500 GW non-fossil power capacity target could peak coal power before 2030,” said Manoj Kumar, CREA Analyst. “Strengthening grid flexibility, storage, and transmission will be key to sustaining this momentum.”
India’s Coal Economics Have Flipped
A new report from Ember (October 2025) adds powerful economic validation to CREA’s projection.
Titled “Adding coal beyond the National Electricity Plan 2032 targets is uneconomical for India,” Ember’s findings confirm that building more coal plants is no longer cost-effective or necessary.
Ember’s least-cost operations model shows that if India meets its National Electricity Plan (NEP) 2032 targets for renewables and storage:
- 10% of new coal units built after FY2024–25 will be completely unutilised by 2031–32
- 25% of the coal fleet will be heavily underutilised
- Coal-based electricity will become 25% more expensive by 2031–32 as utilisation drops
“Building coal beyond the current pipeline is neither necessary nor economical for the country,” said Neshwin Rodrigues, Senior Energy Analyst at Ember.
Ember’s study aligns with CREA’s broader conclusion — India’s clean energy growth is not only sufficient to meet new demand but also the cheapest and most reliable path forward.
Indonesia: Big Solar Vision vs. Fossil Reality
Indonesia’s new president Prabowo Subianto has laid out a bold plan for 100 GW of solar capacity and a 100% renewable power system by 2035. If fully realized, this initiative alone could cause coal power to peak by 2030.
However, Indonesia’s official power plan—the RUPTL 2025–34—still leans heavily on new coal and gas plants. CREA’s analysis warns that without strong oversight and power market reforms, Indonesia’s solar revolution could stall.
“The real opportunity lies in translating this vision into a concrete delivery roadmap that positions clean energy to dominate new capacity additions,” said Katherine Hasan, CREA Analyst.
The Economics of Change
Across all three nations, clean energy’s economic edge is becoming undeniable.
The cost of solar panels has dropped 60% since 2022, while battery storage prices fell 50% between 2022 and 2024. In China, clean energy industries now make up over 10% of GDP, fuelling jobs and innovation. India’s solar bids are now cheaper than coal tariffs, and Indonesia’s strong sunlight potential could soon make solar the most cost-effective option for households.
CREA’s report also highlights that these clean energy drives align with national priorities: energy independence, industrial growth, and improved air quality.
A Common Threat: Coal’s Last Stand
Despite rapid progress, the report warns of a looming obstacle—new coal projects. China currently has 230 GW of coal-fired power under construction, and India plans 100 GW more by 2035. “Unchecked coal power expansion risks creating powerful vested interests that could delay the energy transition,” Myllyvirta cautioned. A rapid phase-down post-2030, he added, could cut emissions equivalent to India’s entire 2019 CO2 output.
A Turning Point for BRICS and the Planet
If successful, China, India, and Indonesia would join Brazil, South Africa, the UAE, and Ethiopia—other BRICS members that have already peaked their power emissions—transforming the bloc into an unexpected climate leader.
But the next few years are pivotal. Whether these nations sustain their clean energy momentum or fall back into fossil dependence could determine the world’s ability to meet the goals of the Paris Agreement.
As CREA concludes in the report, the road to peaking emissions is now open—what remains is the political will to walk it.
