How climate change is putting these natural sites at risk :: Lonely Planet India

Climate change is a serious issue

Lately, our planet has endured several calamities like cyclones in West Bengal and Maharashtra to human carelessness that caused wildfires in Australia and California. The increase in global warming is affecting our eco-system in numerous ways. Rising sea levels, melting ice caps, deforestation, flooding, and human infiltration are some of the many threats affecting natural sites around the world.

A tough and immediate reduction in greenhouse gases would only limit frothing sea levels to 50cm. While carbon dioxide emissions did take a fall of 17% in April 2020 due to COVID-19, there is no assurance this will be made permanent due to policy change and the Climate Action Tracker report from June 2019 shows that prior to the pandemic, we were producing more carbon dioxide emissions than ever before.

Here are some major natural sites at risk from climate change.

Zanskar River, India

The Zanskar River is the pride of Ladakh. Many adventure seekers from around the globe flock the destination in time for the Chadar trek, which is impacting the river and its surroundings – causing an unnatural increase in greenhouse gases. Thus, causing the ice sheets to melt. Over the past years, Zanskar has seen a rise in plastic and other forms of human wastes. An increase in temperatures due to global warming is another reason that’s harming its natural ecological system. Some experts say that the ice sheet over the river will melt as early as the end of 2020.

Great Barrier Reef, Australia

Every five years, the Great Barrier Reef Marine Park Authority reports on the current health of the Great Barrier Reef, the largest coral reef system on the planet. The latest prognosis, released in 2019, doesn’t look positive. Climate change is circled red as the reef’s most significant threat and extreme changes in sea temperatures were responsible for mass bleaching of the coral.

Forests are nicknamed the “lungs of the earth”, and coral reefs are seen as the oceanic equivalent. But according to the UN Environment authority (UNEP), more than half of the world’s reefs – which include systems in Belize and the Bahamas – are in danger of deterioration. Limiting global warming to 1.5ºC or less will save more than 10% of the world’s coral; to protect 50%, temperatures mustn’t creep past 1.2ºC.

Ilulissat Icefjord, Greenland

Under the glow of the swirling purples and greens of the northern lights, the Ilulissat Icefjord is arguably the finest natural wonder of Greenland. Fed by the growing Jakobshavn Glacier, the Icefjord creaks as it calves and creeps past the brightly-painted houses of Ilulissat on the west coast of the Danish territory.

But it’s in trouble. The Arctic is warming twice as quickly as the global average and the loss of the polar sea ice is a tangible, physical manifestation of the planet getting hotter. There may be no sound more heart-breaking than the crashing thunder of the Icefjord collapsing into the sea. Not only are ice sheets essential for cooling the earth as the white ice reflects the sun’s rays into space, but the 413 gigatonnes of ice we are losing each year directly contributes to rising sea levels.

Venice, Italy

Venice is often associated with climate change because rising sea levels lead to greater incidents of the city flooding. Nearly 36 million visitors came to marvel at the splendour of this historic lagoon-built city in 2019. With gold-gilded basilicas, grandiose marble palaces, galleries filled with dramatic Renaissance art and slow romantic gondola rides through its canals, it’s a remarkable destination to visit.

Regular flooding, particularly after exceptional high tides, is a real issue for the city; one that’s been aggravated by the dredging of deep-water canals to allow cruise ships into certain channels. According to the Venice Resilience Lab, the number of tides above 110cm has doubled each decade since the major flood of 1966.

To protect the piazzas and architecture from sustained water damage, the city has been building three retractable floodgates across the main lagoon inlets since 2003. Beset with delays and bankrolled to a cost of $6.5 billion (at the last available estimate), Project MOSE should allow Venice to control the lagoon’s water levels once complete. However, a Unesco report suggests that the gates will need to be used frequently to combat rising sea levels before the barriers are eventually overwhelmed.

Galápagos Islands, Ecuador

Spliced by the equator, these extraordinary volcanic islands 1000km west of Ecuador, are home to one of the most fascinating but delicate ecosystems on the planet. Creatures sublime and strange mingle without much – though sadly increasing – interference from humankind. As such, a quarter of its 2900 marine animals and a third of its native trichophyte plants remain endemic.

As well as growing concerns regarding overfishing and trying to control invasive species, climate change is expected to take a toll on the ecosystem. The acidification of warming oceans, changes in rainfall patterns and extreme weather are all likely to upset the balance on the islands.

According to UNEP, the biggest disruptor will be the El Niño weather pattern, a natural climatic occurrence that periodically warms sea surface temperatures. With climate change, the number of severe El Niño years are likely to double in the next two centuries. The results could be disastrous for the depleted Galápagos penguins and marine iguana populations, which lost 75% and 90% of their numbers respectively to El Niño events since the 1980s.

The Maldives

The Maldives has long been the dream destination for deep-pocketed honeymooners: a string of 1200 white-sand islands, spread loosely in the Indian Ocean like a scattering of gold coins. Its warm cyan seas, coconut palms, and glistening coral reefs are nature’s paradisiacal tonic to the human-made opulence of the country’s five-star-and-above, don’t-lift-a-finger resorts.

But the country has an elevation problem. Its highest natural point is the eighth tee of a golf course on Villingili Island which, at a mere 5.1m above the waves, is unlikely to give anyone a high-altitude nosebleed; many of its other islands merely paddle above the waves. Sea level rises wrought by a temperature rise of 2°C or above will likely spell the submerging of this atoll-based nation – along with other low-lying archipelagos, such as the Fijian islets and the Marshall Islands.

Steps we should take to reduce our carbon footprint

From minimizing our impact when flying to not flying at all, choosing to live responsibly, and travelling sustainably can help to reduce the impact of climate change.
