Faced with the critical state of Antarctic ice, we must go for renewables
2060 is the year set by a group of scientists in which Antarctica could reach its tipping point if a series of "ambitious measures" are not taken to curb global warming, because if it continues on its current trajectory the consequences would be irreversible on timescales of several centuries.
According to new images of the seabed, the huge Thwaites Glacier, the size of the UK in West Antarctica, is already in a phase of rapid retreat. It is also known as the “glacier at the end of the world” because of its high risk of collapse and threat to global sea level rise. What’s the problem? It could thaw faster than expected!
The new study led by marine geophysicist Alastair Graham of the University of South Florida’s School of Marine Sciences adds cause for concern that this “hangs in the balance”. The researchers found that, at some point over the past two centuries, the base of the glacier broke free from the seafloor and retreated at a rate of 2.1 kilometres (1.3 miles) per year. That is twice the rate scientists have seen over the past decade, suggesting that Thwaites could experience rapid retreat in the near future, they argued in the study.
For the first time, the researchers mapped a critical area of the seafloor in front of the glacier in high resolution, giving them an idea of how Thwaites moved in the past. They documented more than 160 parallel ridges that were created as the edge of the glacier retreated and rose and fell with the daily tides, and to collect the images they launched a state-of-the-art robotic vehicle called “Ran”. The presence of ice allowed them to map the seafloor area and access the front of the glacier for the first time ever.
This situation makes us think once again that we have to implement measures to combat climate change, one of the most important challenges. To do so, we must focus on renewable energies, those clean and inexhaustible sources of energy.
And… What are our sustainable development goals?
- Eradicate poverty and ensure healthy lives.
- Promote innovation and resilient infrastructure by creating communities and cities capable of sustainable production and consumption.
- Universalise access to basic services such as water, sanitation and sustainable energy.
- Reduce global inequalities, especially gender inequalities.
- Caring for the environment by tackling climate change and protecting oceans and terrestrial ecosystems.
- Foster collaboration between different social actors to create an environment of peace and sustainable development.
At Univergy Solar, we are committed to the environment, with a special interest in the development, construction and operation of solar photovoltaic engineering projects, based on sustainable development. Because sustainable economic activity is only possible if we consider ourselves an active part of the global society.
