Climate change is real and everything around the world is rapidly changing.
There’s a lot that needs to be done to save what we have and what we have taken for granted as mother earth has started sending us alarming signals.
One of the most recent warning by researchers is that half the world's sandy beaches might be wiped out by 2100.
Even if humanity sharply reduces the fossil fuel pollution that drives global warming, more than a third of the planet's sandy shorelines could disappear by then, crippling coastal tourism in countries large and small, they reported in the journal Nature Climate Change.
"Apart from tourism, sandy beaches often act as the first line of defence from coastal storms and flooding, and without them impacts of extreme weather events will probably be higher," lead author Michalis Vousdoukas, a researcher at the European Commission's Joint Research Centre, told a section of the media.
"We have to prepare."
Some countries, such as the United States, are already planning extensive defence systems, but in most nations such massive engineering schemes will not be unfeasible, unaffordable or both.
Australia could be hit hardest, according to the findings, with nearly 15,000 kilometres (more than 9,000 miles) of white-beach coastline washed away over the next 80 years, followed by Canada, Chile and the United States.
The 10 countries that stand to lose the most sandy shoreline also include Mexico, China, Russia, Argentina, India and Brazil.
'A landmark advance'
A less dire scenario, called RCP4.5, would see humanity cap global warming at about three degrees Celsius, which is still far more than the "well below 2C" limit called for in the 2015 Paris Agreement.
Under RCP8.5, the world will lose 49.5 percent of its sandy beaches by 2100 -- nearly 132,000 kilometres of coastline.
Even by mid-century, the loss would be more than 40,000 kilometres.
The increasingly likely RCP4.5 outlook would still see 95,000 kilometres of coastline shorn of its sand by 2100, most of it within the next 30 years.
The UN's science advisory group, the Intergovernmental Panel on Climate Change (IPCC), projected in a major report last September a sea level rise of a half metre by 2100 under the more optimistic scenario, and 84cm under RCP8.5.
Many climate scientists, however, say these estimates are too conservative, and have predicted in peer-reviewed work that the ocean watermark will rise twice as much.
Experts not involved in the new findings said they should sound an alarm.
Greta Thunberg has said that the world needs to learn the lessons of coronavirus and treat climate change with similar urgency.
Peering into the lake, the village elder struggled to pinpoint where beneath the hyacinth and mesquite weeds lay the farm he lived in his entire life until the water rose like never before and swallowed everything.
Power outages compounded the misery of millions of people wilting in a heatwave across India and Pakistan on Friday, with experts blaming climate change for an early onset of roasting summer temperatures.
Pakistan is home to more than 7,000 glaciers, more than anywhere else on Earth outside the poles. Rising global temperatures linked to climate change are causing the glaciers to rapidly melt, creating thousands of glacial lakes.
