Not all things bring cheer when they are headed on an upward path. Nasa's weekend report on how the global temperature is on the upward spiral not only tells us that April was the hottest month on record with 1.11 degrees Celsius temperature, but also the seventh consecutive month to have broken previous records by largest ever margin. Simply put, it is getting hotter and will continue so until there is no conscious effort to mitigate the global warming.
The data spanning over 136 years explains how the rise has been consistent and has drastically shot up in the past couple of decades. Climate scientists, however, are not surprised as they have been warning about the phenomenon since long.
“Climate scientists have been warning about this since at least the 1980s. And it’s been bloody obvious since the 2000s. So where’s the surprise? The interesting thing is the scale at which we’re breaking records,” said Andy Pitman, director of the ARC Centre of Excellence for Climate System Science at the University of New South Wales in Australia, was quoted as saying in The Guardian. “It’s clearly heading in the wrong direction."
El Niño – a climate cycle deemed responsible for the soaring temperatures – has been the strongest on record in 2015 according to this report by Skymet. A strong El Niño year is always followed by hot summer conditions. The stronger and longer duration of the phenomenon, the harsher the summers tend to be, states the report.
Eric Holthaus, a meteorologist, was quoted as saying in The Independent: “It’s scary. We knew an El Nino would impact things, but I don’t think anyone expected this jump.”
Explaining that the spiraling global temperature is the aftermath of human activities, climate scientist, Ed Hawkins, said on Twitter: "Humans are largely responsible for past warming so we have control over what happens next. Lots of factors affect Earth's climate, but human activities enhance the greenhouse effect, keeping more of the sun's energy to warm planet."
Hawkins came up with an attractive animation on the alarming spiral which shows the pace at which the temperatures have risen since 1850.
Furthermore, a statement released by Australian Research Council in March revealed that the most pristine section of the Great Barrier Reef, UNESCO World Heritage centre and Australia's Great Natural Wonder, is currently experiencing the worst bleaching event in its history – a consequence of warmer water temperature.
Aerial surveys of over 500 coral reefs from Cairns to Papua New Guinea showed how overwhelming majority of reefs were ranked in the most severe bleaching category with scientists already reporting up to 50 percent mortality of bleached corals, says the report.
The repercussions of climate change were impending. It may continue to persist or worsen due to the indifference towards preserving the nature.
All we can do is either act or be a mute spectator.
