Climate disruption in overdrive (1)

As the presidential campaign circus dominates headlines across the US, glaring signs the planet is undergoing abrupt anthropogenic climate disruption (ACD) abound. A major study published in Nature Climate Change shows that the planet is warming a stunning 50 times faster than when it comes out of an ice age. The implications of the rapidity of this warming, for those who care to digest it emotionally, are horrifying. The study shows that even if carbon reduction targets are achieved and the planet's temperature is kept below the 2 degree Celsius warming threshold, sea-level rise will still inundate major coastal cities around the world, forcing one-fifth of the total world population of humans to migrate away from the coasts. New York, London, Rio de Janeiro, Jakarta, Cairo, Kolkata and Shanghai will all be underwater. As though to reinforce this point, NASA recently released data confirming that February was the warmest month ever measured globally, at 1.57 degrees Celsius above the preindustrial baseline temperature average. The new record easily smashed the old global temperature record, which was set just one month before in January. This means that while it took from the advent of the industrial age until October 2015 to warm the planet 1 degree Celsius, humans have managed to warm the planet another 0.57 degrees Celsius in just the next four months since then.
As if that isn't enough, a study recently published in the journal Nature Geoscience revealed that carbon emissions are now the highest they have been since the age of dinosaurs, 66 million years ago. According to the study, the current pace of emissions is even beyond the highest-known natural surge of carbon that exists in fossil records, an event that occurred 56 million years ago that was believed by many to be caused by the release of frozen stores of greenhouse gases from the seabed. That ancient release, which drove temperatures up 5 degrees Celsius, is now surpassed by the current surge of carbon release.
Another ominous sign of escalating ACD: The entire Northern Hemisphere surpassed the 2 degree Celsius mark for the first time since human civilization began. Bear in mind that 2 degrees Celsius is the arbitrary, politically agreed-upon warming limit, above which warming is considered "dangerous" to humanity. Former NASA scientist James Hansen debunked that goal over two years ago, when he published a paper showing that 1 degree Celsius was the scientifically proven point of no return. Parts of the Arctic were 29 degrees Fahrenheit warmer than normal in February, which even brought large portions of the Arctic above freezing and into temperature levels more common in June.
Dozens of countries across Europe and Asia set or tied all-time temperature records, and cities across the United States saw record warm temperatures, in which the 2015-2016 winter was the warmest ever recorded.
Winter in the US, according to meteorologists, technically takes place from December through February. This year, that winter was 4.6 degrees Fahrenheit warmer than normal, breaking the previous record, which was set in 1999-2000. Meanwhile, every single US state had winters nearly 2 degrees Fahrenheit warmer than normal, and Alaska's winter was an incredible 10.6 degrees Fahrenheit warmer than normal. Underscoring the severity of what is clearly a planetary warming crisis, the New Scientist reported in early March that earth had its highest-ever annual increase in carbon dioxide levels ever recorded, with atmospheric levels breaching 404 parts per million.
Melting in Greenland is occurring so intensely and quickly that it is "feeding on itself," according to a recently published scientific study. Greenland alone contains enough ice to raise global sea levels by 20 feet. This information is emotionally challenging to take in. It is understandable that people prefer to distract themselves with the minute-to-minute antics of the political and media charade that is the US election cycle, yet it has never been more important to understand what the planet upon which we live and depend is undergoing.
There are several indicators of how rapidly the planet is changing under increasing stressors from ACD. In North America, millions of acres of forests are struggling and under increasing threat, due to the fact that the speed at which the planetary climate is changing is now far, far ahead of the forests' ability to adapt to the hotter and drier conditions ACD has ushered in across vast areas of the United States and Canada. New research shows that all of the forests in the US are officially under threat from ACD. And it's not just forests that are being impacted. The agricultural sector is in big trouble, as crops are being impacted dramatically by the rapidly changing climate. For example, in Montana, a recent study shows that agricultural losses due to ACD could total up to $736 million annually. Panning out, another recent study shows that food scarcity caused by ACD would cause at least half a million deaths across the world by 2050, due to food production being impacted by the effects of ACD.
Making matters worse, a group affiliated with the UN recently released a study showing that an ongoing decline of pollinating species now poses a very dire threat to the global food supply. The report warns that the species responsible for pollinating and promoting the growth of hundreds of billions of dollars worth of crops are facing extinction. Another study, this one published in Nature Climate Change, shows that high-latitude insects, like those in Scotland, face severe declines in population from ACD, due to the fact that they are far more sensitive to warmer temperatures than previously believed. Even as far north as the Arctic, ACD's growing impact on insects is obvious. A recent study shows that warming temperatures are impacting beetle populations, and hence the entire biodiversity of the Arctic. The temperature change is causing the insects to migrate into new habitats, which is having a domino effect that is upsetting the natural balance.
For humans in the far north, ACD's impacts are even more obvious. Intensifying heat is threatening the way of life of the Indigenous population in the Arctic. With the ice disappearing and temperatures continuing to rise, the life cycles and numbers of fish, marine mammals, caribou and polar bears are being altered, which is causing Indigenous communities to face food shortages. The Native populations of the Arctic are dealing with growing despair over the effects of ACD on their lives and communities, and observers are connecting this to a growing array of mental health and social problems.
