Earth Day is celebrated on April 22 every year since 1970. Year on year, the celebration is getting more somber. This year, internet giant Google reminds us of the increasingly fragile state of the planet in four new Doodles featuring images of environmental destruction across the globe.
In time-lapse sequences consisting of Google Earth satellite images taken over several decades, the Earth Day Doodles reveal the scale of glacier retreat on the summit of Tanzania's iconic Mount Kilimanjaro, as well as that covering parts of Greenland's southern Sermersooq region.
The once trademark snow cap of the 19,340-feet-high (5,895 meters) Mount Kilimanjaro has shrunk to less than 10% of its early 20th-century extent and might completely disappear by the end of this decade, according to estimates.
The volcanic mountain, Africa's highest peak, is a popular destination for adventure seekers, but in recent years, conservationists have spoken about rapid changes to its ecosystems, namely, the formation of wetlands due to the thawing ice.
Greenland's glaciers have been suffering a similar fate, mostly due to the combination of warming ocean waters and rising air temperatures, according to NASA.
But it's not just ice melting that portends the climate disasters the planet may be heading for. In Germany, swaths of the Harz Forest Natural Park have fallen prey to bark beetle infestation since 1995, the Google images show.
The final Doodle points at one of the tragedies emblematic of the climate change struggle of the oceans — dying corals. A sequence of images of Australia's Great Barrier Reef provided by the Ocean Agency reveals speedy coral bleaching that struck a section of the reef near Lizard Island between March and May 2016.
Humankind has been slow to jump into action to thwart the progressing climate change despite years of alarm bells from the scientific community. According to a report released by the European Copernicus climate monitoring program today, concentrations of carbon dioxide and methane, the two most worrisome greenhouse gasses, have yet again hit new record levels in 2021, having risen by 2.3 parts per million and 16.5 parts per billion, respectively.
In Europe, average temperatures are already 3.6 degrees Fahrenheit (2 degrees Celsius) above preindustrial levels, Copernicus said. That is 0.9 degrees F (0.5 degrees C) more than the limit of 2.7 degrees F (1.5 degrees C) set by the international community to avoid the more disastrous environmental consequences. Globally, average temperatures are currently about 2.1 degrees F (1.2 degrees C) above pre-industrial levels, Copernicus said.
