Alarm Bells Ringing For Humanity

Two systems: one driven by its primary motive of profit regardless of any externalities, including consequences for the future of life on this planet; the other based on common ownership and democratic control of the means and instruments for producing and distributing wealth by and in the interest of the whole community. Which is the better choice for humanity and the planet?

Study: Today’s Climate Change is 10X Faster Than Any Climate Shift Ever Recorded

 

Scientists expose terrifying rate of global warming and spread of disease that goes along with it

The world’s climate is changing 10 times faster than at any other point in the past 65 million years, Stanford climate scientists Noah Diffenbaugh and Chris Field have found in a new study published in Science.

The study—a review of scientific literature on climate change—shows that the world is not only going through one of the greatest climate shifts in the past 65 million years but is hurtling towards this warming at a troubling speed.
“We know from past changes that ecosystems have responded to a few degrees of global temperature change over thousands of years,” Noah Diffenbaugh, an associate professor of environmental Earth system science, told Stanford News. “But the unprecedented trajectory that we’re on now is forcing that change to occur over decades. That’s orders of magnitude faster, and we’re already seeing that some species are challenged by that rate of change.”
The alarming study comes as international climate scientists reveal in a new article also in Science that climate change is already having an impact on the spread of infectious diseases across the world, in most cases resulting in an “increase of disease and parasitism,” University of Georgia Professor Sonia Altizer, lead author of the study, told Sustainable UGA.
As global warming changes ecosystems across the world, disease hosts, as well as parasites, undergo changes as well. For example, as temperatures climb in the Arctic, parasites develop more quickly. Such changes allow certain species, including a type of lungworm that feeds on muskoxen, to spread more quickly over longer periods during the summer season, leading to greater infection rates for their hosts.

  1. The infective stages of lungworms, like Dictyocaulus viviparous, crawl onto the fruiting bodies of fungi growing on the dung pat. When the sporagiophore explodes its spores, the nematode is also blown away from faecal pat. Important because most cattle-like species won’t eat grass within a certain radius (10m) of the dung.

    Obviously, increasing temperatures will extend the season for transmission, and within limits, the rate of development of the fungal spores. Conversely, very low temperatures will reduce the numbers of larvae and inhibit the formation of fungal fruiting bodies. A rapid warming of the climate, as is now occurring was bound to disrupt the host-parasite balance that has evolved.

  2. Average GLOBAL temperature anomalies are reported on the web by NOAA, GISS, Hadley, RSS, and UAH, all of which are government agencies. The first three all draw from the same data base of surface and near surface measurement data. The last two draw from the data base of satellite measurements. Each agency processes the data slightly differently from the others. Each believes that their way is most accurate. To avoid bias, I average all five. The averages in Celsius degrees are listed here.

    2001 0.3473
    2002 0.4278
    2003 0.4245
    2004 0.3641
    2005 0.4663
    2006 0.3930
    2007 0.4030
    2008 0.2598
    2009 0.4022
    2010 0.5261
    2011 0.3277
    2012 0.3770

    A straight line (trend line) fit to these data has no slope. That means that, for over a decade, average global temperature has not changed.
