NASA reveals how 60 years of climate change have transformed Earth from vibrant blue to a troubled world | – The Times of India


There was a day when looking at the sky stunned human beings with wonder and fascination. The world seemed limitless, its brilliant bright blue waters, green spaces, and dense layer of leaves. The world symbolised harmony and beauty, full of natural wonders. From the outside space, the planet seen was nothing less than magical. But over the last decades, the complexion of our planet has altered radically, a reflection of the cost to the environment of human actions. A once-pure image now presents a filthier scene—a one of tension and decay.

NASA reveals Earth’s changing image from space

The image of a bright blue world glowing against the darkness of space touched hearts all over the world. It was a pioneering picture, showing an unknown perspective that united people and filled them with respect for the world. Several years later, in 1972, Apollo 17 astronauts captured the “Blue Marble” photo—a fully illuminated image of Earth, from the South Pole to all continents. This photo became one of the most widely shared photos in history. It wasn’t just beautiful—it also carried an unconscious message: a request to be kind to and take care of our world.
NASA’s EPIC camera today photographs the Earth much more troubled. While the heavens still shine, they do not emit the same fierce blue that used to be the characteristic of our world. Melting oceans, felled trees, and blanket pollution have altered the hue of the world from above. The destruction that has already occurred to the planet can now be viewed from above, a harsh reminder of what has been achieved by decades of human neglect. Clean ecosystems are now scarred by global warming, and Earth’s once energetic vibrancy wanes.

Consequences of ignoring environmental warnings

Since the 1970s, environmentalists have warned of the dangers of carbon emissions and the increasingly likely threat of global warming. These early warnings were characterised by consistent, systematic voices calling for action to avert the climate crisis that confronts us today. But despite the seemingly clear evidence, the world failed to act on time. Through the decades, these warnings became conclusive evidence. Glaciers melted, islands disappeared, and animals were pushed to the point of extinction, but the world failed to take action swiftly enough to prevent it.

Deforestation and the Amazon’s struggle for survival

The oceans that once teemed with life are also facing extreme alteration. Ocean acidification is among the direst of the dilemmas, going up 30% over recent decades. That has caused sweeping destruction of coral reefs, reducing what we’reere thriving underwater communities into lifeless deserts. Also, plastic contamination has been raging epidemic-style, as millions of tons of plastic rubbish now lie strewn around our oceans. What was once a cradle for life is now a symbol of ecological despair. The oceans, which are so crucial to regulating the climate of the Earth and preserving marine biodiversity, now face attack, also a casualty of human endeavor.
The Deforestation crisis, once one of the world’s most magnificent ecosystems, is disappearing at an alarming rate. Now referred to as the “lungs of the world,” the Amazon loses tens of millions of forest acres annually to deforestation.
With gigantic waves of forest fires in places like Australia and California, where gigantic forests have been reduced to ash. The trees once removed carbon dioxide and maintained our atmosphere, but now they are taken from us, along with precious clean air. The destruction of such forests not only threatens biodiversity but also fuels the climate crisis since trees, when felled, result in increased CO2 levels in the atmosphere. A sign of accelerated climate change between the start of the 21st century and 2015, large areas of natural forest have been cleared and turned into roads and plantations.
This conversion of land has led to the increase in temperature across the world. The last decade has seen a number of heat records broken, with the temperature increasing each year. The winters are shorter and the summers longer and hotter. This is very frequent in the Arctic region, where ice melts at a record pace. Thawing ice in the Arctic is creating new sea routes, but the cost is highest to the environment—ecosystems are lost, and the face of the world is being altered forever.

Challenge of climate action: Can we save our planet in time

The effects of climate change are emerging in sharper and more intense forms. Urban settlements that were previously considered to be safe from natural hazards are becoming more vulnerable to flooding due to sea-level rise.
More frequent and intense heatwaves are impacting human habitation and ecosystems. Freshwater too is increasingly in short supply, with agriculture yields and drinking water sources impacted by droughts. These aren’t local changes—part of a global pattern of disruption that threatens the stability of entire ecosystems and regions. Renewable sources of energy, such as wind and solar power, are on the rise.
More and more countries are taking global warming seriously these days, and international treaties to reduce carbon emissions are more and more popular. Businesses themselves are also under more and more pressure to reduce their footprint, with more and more choosing greener methods of conducting business. Action at a personal level is also on the rise, with more and more adopting sustainable living, reducing waste, and calling for tighter environmental controls.

Australian State culls 700 starving koalas after bushfire, stoking controversy

Australian State culls 700 starving koalas after bushfire, stoking controversy


Snipers in helicopters have shot more than 700 koalas in the Budj Bim National Park in western Victoria in recent weeks. It’s believed to be the first time koalas have been culled in this way.

The cull became public on Good Friday after local wildlife carers were reportedly tipped off.

A fire burned about 20% of the park in mid-March. The government said the cull was urgent because koalas had been left starving or burned.

Wildlife groups have expressed serious concern about how individual koalas had been chosen for culling, because the animals are assessed from a distance. It’s not clear how shooting from a helicopter complies with the state government’s own animal welfare and response plans for wildlife in disasters.

The Victorian government must explain why it is undertaking aerial culling and why it did so without announcing it publicly. The incident points to ongoing failures in managing these iconic marsupials, which are already threatened in other states.

Why did this happen?

Koalas live in eucalypt forests in Australia’s eastern and southern states. The species faces a double threat from habitat destruction and bushfire risk. They are considered endangered in New South Wales, Queensland and the Australian Capital Territory.

In Victoria, koala population levels are currently secure. But they are densely concentrated, often in fragments of bush known as “habitat islands” in the state’s southwest. Budj Bim National Park is one of these islands.

Over time, this concentration becomes a problem. When the koalas are too abundant, they can strip leaves from their favourite gums, killing the trees. The koalas must then move or risk starvation.

If fire or drought make these habitat islands impossible to live in, koalas in dense concentrations often have nowhere to go.

In Budj Bim, Victoria’s Department of Energy, Environment and Climate Action and Parks Victoria have tackled koala overpopulation alongside Traditional Owners by moving koalas to new locations or sterilising them.

But Budj Bim is also surrounded by commercial blue gum plantations. Koalas spread out through the plantations to graze on the leaves. Their populations grow. But when the plantations are logged, some koalas have to return to the national park, where food may be in short supply.

Animal welfare groups say logging is one reason Budj Bim had so many koalas.

It’s hard to say definitively whether this is the case, because the state environment department hasn’t shared much information. But researchers have found habitat islands lead to overabundance by preventing the natural dispersal of individuals.

So why was the culling done? Department officials have described the program as “primarily” motivated by animal welfare. After the bushfire last month, koalas have been left starving or injured.

Why shooters in helicopters? Here, the justification given is that the national park is difficult to access due to rocky terrain and fire damage, ruling out other methods.

Euthanising wildlife

Under Victoria’s plan for animal welfare during disasters, the environment department is responsible for examining and, where necessary, euthanising wildlife during an emergency.

For human intervention to be justified, euthanasia must be necessary on welfare grounds. Victoria’s response plan for fire-affected wildlife says culling is permitted when an animal’s health is “significantly” compromised, invasive treatment is required, or survival is unlikely.

For koalas, this could mean loss of digits or hands, burns to more than 15% of the body, pneumonia from smoke inhalation, or blindness or injuries requiring surgery. Euthanised females must also be promptly examined for young in their pouches.

The problem is that while aerial shooting can be accurate in some cases for larger animals, the method has questionable efficacy for smaller animals – especially in denser habitats.

It’s likely a number of koalas were seriously injured but not killed. But the shooters employed by the department were not able to thoroughly verify injuries or whether there were joeys in pouches, because they were in the air and reportedly 30 or more metres away from their targets.

While the department cited concerns about food resources as a reason for the cull, the state’s wildlife fire plan lays out another option: delivery of supplementary feed. Delivering fresh gum leaves could potentially have prevented starvation while the forest regenerates.

Lessons for the government

The state government should take steps to avoid tragic incidents like this from happening again.

Preserving remaining habitat across the state is a vital step, as is reconnecting isolated areas with habitat corridors. This would not only reduce the concentration of koalas in small pockets but increase viable refuges and give koalas safe paths to new food sources after a fire.

Future policies should be developed in consultation with Traditional Owners, who have detailed knowledge of species distributions and landscapes.

We need better ways to help wildlife in disasters. One step would be bringing wildlife rescue organisations into emergency management more broadly, as emphasised in the 2009 Victorian Bushfires Royal Commission and the more recent Royal Commission into National Natural Disaster Arrangements.

This latter report pointed to South Australia’s specialised emergency animal rescue and relief organisation – SAVEM – as an effective model. Under SA’s emergency management plan, the organisation is able to rapidly access burned areas after the fire has passed through.

Victoria’s dense communities of koalas would be well served by a similar organisation able to work alongside existing skilled firefighting services.

The goal would be to make it possible for rescuers to get to injured wildlife earlier and avoid any more mass aerial culls.

Starlink’s India struggle: spectrum, surveillance, and connectivity

Starlink’s India struggle: spectrum, surveillance, and connectivity


The vast rural expanses of India are often overshadowed by the country’s urban-centric digital growth; digital isolation has long stifled progress. Starlink’s ambitious satellite network now promises to turn night into day, literally and figuratively, by beaming high-speed internet across terrains where cables don’t reach and towers don’t exist. But as this technological advance prepared to bridge the digital divide, it became entangled in a complex web of legal, regulatory, and security challenges. At stake today is not just the rollout of a service but a broader question: can the innovation Starlink represents navigate tradition and sovereignty to bring rural and urban India closer together?

Which regulations apply to Starlink?

In its endeavour to provide satellite-based internet services in India, Starlink must navigate a complex legal and regulatory landscape. The cornerstone of this landscape is the Very Small Aperture Terminal (VSAT) licence from the Department of Telecommunications as required by the Indian Telegraph Act, 1885.

Section 4 of the Act grants the Union government the exclusive privilege to establish and operate telegraphs (interpreted broadly to include modern communication technologies like VSAT) and empowers it to issue licences. Section 7 further authorises the government to frame rules governing such licences.

The Telecom Regulatory Authority of India Act, 1997 established the Telecom Regulatory Authority of India (TRAI), which plays an advisory and regulatory role. Section 11 outlines TRAI’s functions, including making recommendations on licensing terms, spectrum management, and ensuring fair competition, thus significantly shaping the regulatory environment for Starlink.

The newer Telecommunications Act, 2023 governs the allocation of satellite spectrum. While it permits administrative allocation, it also requires Starlink to adhere to the security and pricing norms it outlines. Starlink’s use of Ku-and Ka-band frequencies is subject to the telecom department’s spectrum regulations, which are aligned with International Telecommunication Union standards to prevent interference with other services.

The Satellite Communications Policy, 2000 and the Indian National Space Promotion and Authorisation Centre (IN-SPACe) under the Department of Space further require Starlink to coordinate satellite operations and orbital slot use to avoid conflicts with Indian Space Research Organisation assets, and to align with national space priorities.

Finally, the Information Technology Act, 2000 and the Digital Personal Data Protection Act, 2023 impose obligations related to encryption, data storage, and cybersecurity. National security concerns require Starlink to comply with directives from the Ministry of Home Affairs and intelligence agencies, which may include requirements such as real-time signal tracking and user verification.

Why hasn’t Starlink entered India yet?

Several interlinked factors are contributing to delays in Starlink receiving its operational permits in India. First, obtaining a VSAT licence under the Indian Telegraph Act, 1885 involves rigorous technical and financial assessments by the telecom department, often requiring inter-ministerial consultation.

Second, although the Telecommunications Act, 2023 enables the administrative allocation of satellite spectrum, the pricing and conditions — especially for Ku and Ka bands — are still being negotiated between the department and the TRAI.

Third, a thorough security clearance process led by the Home Ministry and intelligence agencies is underway, complicated by concerns about foreign ownership and potential misuse. These agencies require extensive assurances on data protection and lawful usage before giving the green light.

Fourth, coordination with Indian space infrastructure under IN-SPACe and compliance with the Satellite Communications Policy, 2000 adds further procedural requirements.

All these delays have tangible consequences such as Starlink increasing operational costs and delaying market entry, potentially deterring investor confidence. Nonetheless, Starlink could transform connectivity once operational in India’s remotest regions, reinforcing the need for an enabling regulatory ecosystem.

Has Starlink misuse affected its security clearance?

Reports alleging the misuse of Starlink devices for illegal activities may have likely escalated concerns within India’s security establishment. Such instances, isolated or widespread, could trigger a more stringent vetting process, requiring Starlink to implement robust safeguards such as encrypted data flows, lawful interception capabilities, and enhanced user verification mechanisms.

Compliance with the Information Technology Act, 2000 and the Digital Personal Data Protection Act, 2023 will be scrutinised as well.

Such reports may also strain trust between SpaceX, Starlink’s developer, and Indian regulators and increase the time taken to reach consensus on operating conditions. However, proactive engagement and transparency from SpaceX — such as demonstrating technological safeguards and a commitment to collaborate with Indian authorities — could help rebuild that trust and mitigate delays.

What will Starlink cost in India?

Starlink’s pricing in India remains speculative, but several indicators suggest the service may launch at a premium. The high capital cost of deploying low-earth orbit satellites combined with licensing and spectrum charges under the Indian Telegraph Act, 1885 and the Telecommunications Act, 2023 will likely drive up initial service rates.

Equipment cost, comprising the user terminal (dish), router, and setup, could also be significant for households in rural India. Monthly subscription fees may remain out of reach for low-income communities unless supported by subsidies or government-backed digital inclusion initiatives.

Although positioned as a rural connectivity solution, the service may initially cater to institutions, businesses, and relatively affluent individuals in remote areas. Its edge lies in offering high-speed, low-latency internet where terrestrial service providers struggle. Over time, as economies of scale reduce hardware costs, affordability and access could improve if regulatory support emerges.

Why does Starlink matter?

Starlink’s regulatory experience in India offers critical insights into the delicate interplay between innovation, law, and sovereignty.

It underscores the importance of early, structured dialogue between technology providers and government regulators, the need for globally agile companies to adapt to local frameworks, and the centrality of national security in shaping digital infrastructure policy. It also reminds us that spectrum, like sovereignty, is a finite national resource: its fair and efficient allocation demands a robust and forward-looking regime.

These lessons are especially pertinent as India positions itself as a global digital leader.

Welcoming technologies like Starlink while upholding sovereignty, security, and equity requires a regulatory environment that is transparent, predictable, and innovation-friendly.

However, perhaps more symbolically, Starlink’s journey is not just about satellites and signals; it is about bridging divides. Satellite internet holds the potential to unify rural to urban not merely in connectivity but in opportunity, voice, and visibility.
