Save the Planet: we only have one

Save the Planet: we only have one

KÆLTIA’s Team in its aim to contribute with the global awareness of the Climate Change, summarise below some critical news:

  • Forces profound and alarming are reshaping the upper reaches of the North Pacific and Arctic oceans, breaking the food chain that supports billions of creatures and one of the world’s most important fisheries.
  • The lifecycle of a microplastic begins with crude oil, extracted from deep below the Earth’s surface, being chemically refined and spun into fibers for textiles, or molded into single-use disposable items. Over time, these items break down into microscopic bits of plastic that can now be found in our waterways, on mountaintops, and even in the most remote places on Earth. The human health impacts of microplastics are very well documented. We now understand that microplastics can cause decreased fertility, decreased major organ function, chronic inflammation, neurotoxicity, intestinal barrier dysfunction, cell death, impaired hormonal function, potential harm to fetal development, and more. And their small size means that reducing their impacts must come from prevention, not clean up. We must understand that in facing ‘microplastics,’ we are facing the behemoth global fossil fuel industry.
  • Atmospheric carbon dioxide (CO2) levels have increased significantly over the last 50 years, resulting in higher global temperatures and abrupt changes to Earth’s climate. Carbon capture and storage (CCS) is one of the new technologies that scientists hope will play an important role in tackling the climate crisis. It involves the capture of CO2 from emissions from industrial processes, or from the burning of fossil fuels in power generation, which is then stored underground in geological formations. CCS will also be key if we want to produce “clean-burning” hydrogen from hydrocarbon systems.
  • The massive Thwaites glacier in West Antarctica contains enough ice to raise global sea levels by 65cm if it were to completely collapse. And, worryingly, recent research suggests that its long-term stability is doubtful as the glacier haemorrhages more and more ice.
  • When winds loft fine desert dust high into the atmosphere, iodine in that dust can trigger chemical reactions that destroy some air pollution, but also let greenhouse gases stick around longer. The finding, published in the journal Science Advances, may force researchers to re-evaluate how particles from land can impact the chemistry of the atmosphere.
