- Social media channels are now full of "10-year challenges" that compare consumer images from 2009 and 2019.
- Environmental activists are using the tendency to draw attention to how much Earth has changed over the past 10 years, posting side-shots of the recent transformation of our planet.
- This year began with a lot of depressing news about climate change: last year was the hottest year for the world's oceans (which are also warming faster than we thought) and Antarctic ice melts faster than it used for.
The New Year brought one or two blows to bad news about the world's oceans.
Not only was 201
So, when a viral photo challenge occurs in which consumers compare themselves from 2009 to today, some environmentalists took the opportunity to highlight their own "10-year challenge" on Earth.
Sites like Reddit and Instagram explode with posts that require greater public awareness of the impact of climate change. While the initial challenge is to provide a visual representation of the way someone is mature or changed, the climate change versions give a more serious message: this is the 10-year challenge that we need to focus on. Many of the 10-year comparative pictures show melting glaciers – one of the most visually dramatic effects of the warming planet. The melting glaciers mean that the Northern and Southern Poles are slowly getting provisions (not good). In the worst case, called "pulse", warmer waters can cause the collapse of the glaciers that keep Antarctica and Greenland ice sheets. This will send huge amounts of ice to the oceans, which can lead to a rapid rise in sea level worldwide.
If a pulse occurs, the sea level in South Florida may increase by 10 to 30 feet by 2100. But as water – like most things – expands when warmed up, raising sea levels is inevitable, even if ice sheets are unavoidable. does not melt as the oceans absorb 93% of the extra heat that greenhouse gases capture in the atmosphere. One thing is to talk about these threats in an abstract way. But this is another game when we see visual evidence.
