https://castlehomecomfort.com/about-us/ Last week, we received this scary\u00a0bulletin<\/a> out of Berkley, California:<\/p>\n

A prestigious group of scientists from around the world is warning that population growth, widespread destruction of natural ecosystems, and climate change may be driving Earth toward an irreversible change in the biosphere, a planet-wide tipping point that would have destructive consequences absent adequate preparation and mitigation.<\/p><\/blockquote>\n

Since the warning was featured<\/a> in a prominent journal, many<\/a>\u00a0in mainstream media (and the enviro-blogosphere) dutifully treated it as the latest sky-is-falling alert.<\/p>\n

Order Soma Online The New York Times<\/em>, taking the sober, detached approach,\u00a0asked<\/a>:<\/p>\n

Get Tramadol Online Are we nearing a planetary boundary?<\/p><\/blockquote>\n

http://www.amandasatoz.com/?page_id=1322 That headline is a nod to a much-discussed concept laid out<\/a>\u00a0in Nature <\/em>several years ago\u00a0(you can read the expanded version\u00a0here<\/a>), which made the case for “a safe, operating space for humanity” by identifying thresholds for\u00a0climate change, ozone depletion, ocean acidification, biodiversity, freshwater use, the global nitrogen and phosphorus cycles, and land use change.<\/p>\n

While the main essay got gobs of attention, it’s worth recalling that Nature <\/em>also hosted<\/a> separate commentaries (seven of them) on the planetary boundaries thesis. In its introduction, Nature<\/em> asked:<\/p>\n

https://growthjourneytherapy.com/careers/ But do we understand the Earth system well enough to know the real limits to environmental degradation? And if we can define them, even roughly, would doing so ultimately help or hinder efforts to protect the planet?<\/p><\/blockquote>\n

Those questions have now been taken up by the Oakland-based Breakthrough Institute, in a blunt critique<\/a> of the planetary boundaries framework, which they consider to be “a misleading guide to global environmental challenges.”<\/p>\n

Lorazepam Purchase Online Here’s the thrust of Breakthrough’s report:<\/p>\n

The Earth has entered the Anthropocene, a time in which humans are the dominant\u00a0force shaping all Earth systems. All of the nine systems and processes identified\u00a0by Rockstr\u00c3\u00b6m et al. are important determinants, albeit in complex ways, of human\u00a0welfare\u00a0 “\u201d indeed, they enable life on this planet to exist. They all need to be managed wisely and consciously. The planetary boundaries concept was suggested as a\u00a0framework for doing so, and it makes several important contributions worth highlighting. It brings resilience thinking and complex systems theory to the center of the\u00a0debate, and draws attention to the many interrelated elements and processes of\u00a0the Earth system . However, our review of the framework has identified some serious\u00a0flaws, which together make planetary boundaries a poor, even misleading, answer\u00a0to the challenge of planetary stewardship. The implications of this review apply not\u00a0only to the planetary boundaries concept in itself, but to Earth Science as a whole,\u00a0especially as regards the way it interfaces with policy making.<\/p><\/blockquote>\n

Purchase Xanax Online In two follow-up posts that will appear tomorrow, I’ll delve more deeply into the specific criticisms made by the Breakthrough Institute, including elaboration from the report’s lead author. Meanwhile, Jon Foley<\/a>, an earth scientist at the University of Minnesota, and a contributing author of the 2009 planetary boundaries paper in Nature<\/em>, has responded to Breakthrough’s critique on twitter<\/a> and to reporters in email, of which this is an excerpt:<\/p>\n

Their entire report is based on two or three straw-man arguments. \u00a0Sadly, there is nothing substantive here. \u00a0And this isn’t sour grapes, believe me. \u00a0I would welcome a\u00a0useful<\/em>\u00a0critique of the Planetary Boundaries concept! \u00a0In fact, the original publication in Nature included a half dozen sharply worded comments and critiques, and many were extremely useful in improving our collective ideas…I appreciate many of the points they [the Breakthrough Institute] have raised over the years — especially from their original “Death of Environmentalism” essay. \u00a0But I think this report fails to raise anything very new or interesting. \u00a0Too bad: \u00a0I wish they had. \u00a0This concept deserves more scrutiny and challenges.<\/div>\n<\/div>\n<\/div>\n<\/blockquote>\n

https://blackhillsballoons.com/1185-2/ Foley, in an email exchange, has made a more detailed rebuttal. So I’ll be pulling from that in the second post that will look more closely at the Breakthrough Institute’s critique. \u00a0A third, related post will specifically examine how biodiversity has come to fit into the planetary boundaries concept.<\/p>\n","protected":false},"excerpt":{"rendered":"
