Introduced species and biodiversity

Great animation from the California Academy of Sciences about Introduced or exotic species, how and when they become also invasive, and the problems … Sourced through Scoop.it from: www.youtube.com

GR:  This is one of three excellent presentations.  I highly recommend them to anyone who wishes to learn more or teach more about these critical subjects. I once believed that invasive species would wreck Earth’s ecosystems before global warming became a serious force.  The effects of global warming are coming faster than expected, however, and I now believe that stopping our CO2 emissions is our number one priority, a little ahead of reducing our population, preventing invasive species introductions, and so forth.

Big Bank Says It’s Going To Cost A Lot To Do Nothing On Global Warming #Auspol

GarryRogers:

Citi bankAs major corporations appear to catch on to what individual scientists reported decades ago, the pressure on politicians will begin to shift. This is good news, but it isn’t clear that corporate comprehension will be accompanied by actions befitting the emergency conditions that have developed. With more than half of all wild animals gone and with increasing weather extremes, it does little good to say that clean air is better. Moreover, the petroleum industry will probably increase its political investments to counter any clean-energy attractions our politicians might feel.

A new report from Citibank found that acting on climate change by investing in low-carbon energy would save the world $1.8 trillion through 2040, as compared to a business-as-usual scenario. In addition, not acting will cost an additional $44 trillion by 2060 from the “negative effects” of climate change.The report, titled Energy Darwinism, looked at the predicted cost of energy over the coming decades, the costs of developing low carbon energy sources, and the implications of global energy choices.

“What we’re trying to do is to take an objective view at the economics of this situation and actually look at what the costs of not acting are, if the scientists are right,” Jason Channell, Global Head of Alternative Energy and Cleantech Research at Citi, told CNBC. “There is a cost to not doing this, and although there is a cost to acting, what we’re trying to do is to actually…

Court maintains river flows for Northern California salmon

“FRISCO — Life has been tough for California’s freshwater fish during the state’s extended drought. But some salmon in the northern part of the state will have a fighting chance after a federal judge last week decided to maintain a key flow program aimed at boosting flows in the Trinity River.

“The Trinity is a tributary of the Klamath River, where major salmon runs are currently facing the threat of a major fish kill due to the drought. U.S. Judge Lawrence O’Neill, based on Fresno, California, ruled that the risks from shutting down a federal program to release additional reservoir water to protect the salmon were too great, and the potential benefit to irrigators too uncertain.

“The ruling came in response to a request by a coalition of California Central Valley agribusiness and irrigators to turn off the water in the Trinity River.”  Sourced through Scoop.it from: summitcountyvoice.com

Response to Stephen Corry in Truthout criticizing parks and wildlands protection

Article by George Wuerthner (photograph).

“Stephen Corry is the founder and director of Survival International, an organization that seeks to protect tribal people’s rights. While a worthy goal, Corry, unfortunately, seeks to blame conservation for many of the ills facing tribal people, rather than recognizing that conservation is ultimately the best way to retain and protect native culture from the rapacious indulgences of modern industrial society.

“In his essay attacking the national park ideal, “The Colonial Origins of Conservation” [http://www.truth-out.org/opinion/item/32487-the-colonial-origins-of-conservation-the-disturbing-history-behind-us-national-parks], Corry repeats factual errors of both omission and misinterpretation.

“Corry’s assertions align with a larger movement that seeks to denigrate conservation goals and ideals. These same misinterpretations now dominate many critiques of national parks coming from predominately politically left-leaning academics in fields like anthropology, history, and political science which celebrate humanity’s role on Earth. The arguments from this camp are often very similar to those in business and industry who advocate human control, exploitation, and domination of the Earth.

“Ironically, Corry starts his essay by asserting that “Many people root their attitudes and lives in narratives that they hold to be self-evidently true.” Yet he seems unaware of his guilt in this matter.”  Sourced through Scoop.it from: www.thewildlifenews.com

Predators and the food chain and preventing the suburban extinction of small native creatures

“It is springtime here in Mount Waverley, close to the Reserve. The air is filled all day with the anguished squawks of smaller birds vainly trying to divert enormous crows from taking babies from their nests. Pairs of noisy miners are squawking at crows; by dusk, they must be exhausted. In our reserve, the Australian raven terrorises the other birds and dive-bombs the smaller dogs. The bellbirds keep their portion of the reserve, and will not let other birds colonise their areas.

“Every spring there are fewer little birds. Wrens and tits, which were quite plentiful in our garden twenty years ago, seem to have gone. Crows can be seen sometimes flying down the street with little birds in their beaks. We had no crows twenty years ago here. They are out of their ecological niche, whether native or exotic. The little birds have an ecological function in getting rid of noxious insects and other garden pests and these proliferate without them.

“Surely small birds have enough predators with cats, foxes and cars. Surely there is no need to protect all of the growing hordes of native crows or Australian ravens, on the grounds they have an important role in the food chain and they are native.  Sourced through Scoop.it from: www.onlineopinion.com.au

EPA Kicks Off Climate Change Season

posted on: Sunday, August 30, 2015

In June 2013, President Obama announced an ambitious Climate Action Plan, to reduce greenhouse gas (GHG) emissions and mitigate the impacts of climate change. To implement the Plan, the United States Environmental Protection Agency (EPA) has initiated or completed a series of significant rulemakings this summer, all of which are controversial. As a capstone, President Obama is initiating numerous actions to “accelerate America’s transition to cleaner sources of energy and ways to cut energy waste.” Loan guarantees and energy efficiency grants of over $12 billion are now available to further reduce GHG emissions in the United States. Each of these actions affects the cost of energy, transportation and construction across the United States.

These actions include the following:  . . . . Sourced through Scoop.it from: www.natlawreview.com

Facts About Climate Change You Need to Know

Climate change and its effects are peeking at us from the sky, the land, and the sea.  Few of us have noticed these first small effects, but that doesn’t mean they aren’t real, or that they will not grow.  I just ran across three reports by a specialist in threat analysis that you must read.  These well-documented reports describe an effect of climate change that hasn’t made the news yet.  It will begin making the news as people realize that it could be the great destroyer of life on Earth.

The comments following these posts are helpful.  Be sure to read the comments for at least one of them.
