The Earth’s poles may be about to flip – and the consequences could be ‘dire’

Comments Off on The Earth’s poles may be about to flip – and the consequences could be ‘dire’

Over the past 200 years, the Earth’s magnetic field has been getting weaker . Researchers believe that this could be a sign that the poles are about to flip – and the consequences could be “dire,” according to some scientists. If a flip happens, it could knock out power grids, alter the climate, and expose us to solar winds that could puncture the ozone layer. The poles have switched regularly throughout Earth’s history. The last time they flipped was 780,000 years ago. Since the poles normally switch every 200,000 – 300,000 years – according to NASA – we are well overdue for a change. Over the last two centuries, the magnetic field generated by the Earth’s molten core has weakened 15 percent, lending further evidence to the fact that the poles are getting restless. Related: The Earth’s magnetic field is weakening ten times faster than expected If the poles flip, it could confuse animals that rely on magnetic fields for migration, and it could lead to more radiation from the sun reaching life on the planet, according to studies . This would lead to an increase in the incidence of cancer – or at least require us to protect ourselves better from the sun. In a worst-case scenario, the flipping poles could wipe out power grids by damaging satellites that control grid infrastructure and could impact the climate by changing cloud cover. According to researcher Daniel Baker , we don’t know for sure when the poles could flip. The poles have been known to shift and move, ultimately snapping back into place. And while it certainly wouldn’t be a doomsday scenario for the planet, it would be wise to prepare for the event, so that the impact isn’t challenging for humanity.

Storm ‘unfreezes’ North Pole, causing temps 50 degrees higher than normal

Comments Off on Storm ‘unfreezes’ North Pole, causing temps 50 degrees higher than normal

When the going gets tough, there is often a lot of talk about hell freezing over. In reality, it’s the opposite we have to worry about. Temperatures at the North Pole this week are 50 degrees higher than usual for December. Let that sink in for a moment; that’s 50 as in five-zero. That’s pretty disconcerting on its own, but things get hairier when you learn that the temperature actually rose above freezing, at the North Pole, in winter. All global warming naysayers can now step directly off. Read the rest of Storm ‘unfreezes’ North Pole, causing temps 50 degrees higher than normal

New “Polar Code” Signed to Protect Polar Regions as Shipping Increases

Comments Off on New “Polar Code” Signed to Protect Polar Regions as Shipping Increases

The International Maritime Organization has just signed off on an International Code for Ships Operating in Polar Waters, more simply known as the Polar Code . This was developed in response to already increasing shipping activity in the polar regions, which is expected to grow further in the Arctic in particular due to reductions in sea ice . New shipping lanes are opening, making it necessary to adopt measures to protect sailors and passengers in such dangerous conditions, as well as to protect the vulnerable polar regions from environmental disasters.

North Pole Could be a Viable Shipping Route by 2050

This would slash costs of transporting goods between Europe and China, Laurence C. Smith and Scott R. Stephenson wrote in the journal PNAS, but opening the northern sea route will pose a host of new economic, environmental and political challenges.

UN Warns of Harmful Resource Rush as Arctic Ice Melts at Record Rate

Comments Off on UN Warns of Harmful Resource Rush as Arctic Ice Melts at Record Rate

Photo via Shutterstock This week, the United Nations’ Environment Programme released a new report warning that a rush for Arctic resources would threaten an already fragile ecosystem . As Arctic ice melts at a rate never seen before , many are concerned by the unfolding ecological catastrophe—but others are seeing dollar signs. Melting ice is making it easier for humans to extract minerals and fossil fuels from the Arctic—which, ironically, is the very activity that is causing the ice to melt.  Read the rest of UN Warns of Harmful Resource Rush as Arctic Ice Melts at Record Rate Permalink | Add to del.icio.us | digg Post tags: Achim Steiner , arctic ice , arctic sea ice , Climate Change , Denmark , fossil fuels , global warming , greenland , Iceland , melting ice , mining , north pole , russia , UN , United Nations , United Nations Environment Programme , united states

Comments Off on How Fox News Manufactures, Spreads Anti-Climate Talking Points

One of the primary reasons that many Americans remain confused about climate change is that the cable news network that they get their news from actively works to keep them confused. It’s hardly a secret that Fox News sets and follows a politically motivated agenda — convincing folks climate change is a hoax is just one of its planks

Martin Lamonica over at CNET’s Green Tech has a good post about yet another environmental issue where progress is too slow: The recycling of metals, especially from end-of-life electronics. “Less than one third of about 60 metals had an end-of-life recycling rate over 50 percent and 34 elements had a recycling rate below 1 percent
