Some scientists, Guy McPherson included, fear that climate disruption is already so serious, with so many self-reinforcing feedback loops already in play, that humans are in the process of causing our own extinction. August, September and October were each the hottest months ever recorded, respectively. Including this year, which is on track to become the hottest year ever recorded, 13 of the hottest years on record have all occurred in the last 16 years. Coal will likely overtake oil as the dominant energy source by 2017, and without a major shift away from coal, average global temperatures could rise by 6 degrees Celsius by 2050, leading to devastating climate change.

As we slide now into flu season, into a time of year when we are normally braced for winter diseases, colds, flus, sick days and cancelled plans, the American people has also now been truly exposed to another disease entirely: the excruciating truth about our health care system’s dysfunction — and the prognosis doesn’t look good.
The single greatest truth underlying the Ebola tragedy is that humanity is systematically dismantling the ecosystems that make Earth habitable.

We are in uncharted territory with the Ebola virus disease (EVD). The last time we had a plague that was this deadly was the Black Death in the 14th century, when there were only 450 million people in the world. That pandemic killed 30% to 70% of the population. There is no benchmark for EVD, which kills 3 out of 4 people it touches, and is emerging into a global population of 7 billion.

However, like goggling tsunami onlookers, the world’s governments and most of its citizens seem oblivious to the magnitude of the risk. People sometimes even complain they “don’t want to hear any more bad news”, as if not hearing it somehow prevents it from happening.

As has been mentioned in these dispatches previously, the planet is now in the early stages of its sixth mass extinction event, and humans are indeed responsible, according to yet another published study, this one in Science. According to the study, large vertebrate animals (megafauna), which include elephants and polar bears, face the steepest decline since they require large habitats and are targeted by human hunters. The loss of megafauna places ecosystems off balance and leads to consequences like massive rodent infestations that proceed to impact the well-being and stability of a large segment of species, including humans. The study highlights how the particularly steep decline of megafauna we are seeing now is characteristic of all the previous mass extinction events.
“Atmospheric methane release is a much bigger problem than atmospheric carbon dioxide release, since methane is ~20 times more powerful greenhouse gas,” he writes. It’s a sign of a worst-case scenario cascading environmental collapse.
