Rocking the Anthropocene

If media attention is any measure of popular thinking- then we have indeed finally arrived in the Anthropocene. Thanks to the leadership (and hard work) of Jan Zalasiewicz, who initiated and convened the Anthropocene Working Group of the International in London two weeks ago, there has been a true media feeding frenzy on the Anthropocene (see recent media roundup below). […]

Anthropocene is forever

“Global warming is essentially forever.” states David Archer in a nice blog post at fast company about the long-term effects of our current carbon emissions to the atmosphere. Yet more evidence that the Anthropocene is here to stay. Reminds me of one of my first blog posts – Is managing global climate now our duty? Just as we’ve made the […]

Brave new biosphere

What kind of biosphere do you want? Great question! And great to see it connected with beautiful prize-winning graphics at visualizing.org. But on thinking further, it seems clearer than ever that the inspiration behind this- the Planetary Boundaries concept, is going completely in the wrong direction. I had my reservations about the original planetary boundaries work- now these graphics concern […]

Botkin’s biosphere: ahead of its time

“We cannot expect nature to remain in a constant condition and thus provide us with a simple solution to the questions of what is “natural” and what is desirable.” (Botkin 1990, p 181) . Just one of many great thoughts in Daniel Botkin‘s 1990 classic: Discordant Harmonies: a New Ecology for the Twenty-first Century. I’d seen Botkin’s Environmental Science textbook, […]

The war with nature is over and we’ve won!

What happens when humans finally win the war with nature and end up in charge of ecology? A question for the future? Think again. In “Peak Wood: Nature Does Impose Limits”, John Perlin describes what happens when human societies, starting in prehistory, have completely transformed their ecosystems and ultimately themselves, by clearing away forests to improve hunting and gathering, for […]

Carbonware: Googling forests, Windows on your carbon

With carbon, climate and COP 15 in the news, Google and Microsoft are now battling over carbon mindshare, introducing the latest web-based “Carbonware” designed to help combat carbon emissions and global warming. These add to a growing list that includes the many “carbon footprint calculators” designed to enlighten us on our carbon emissions and the activities we undertake that cause […]

On Doctoring the Planet

Our planet is heating up in a hurry! Call in the Earth doctors! Let’s fix the planet! Now that we’ve pushed Earth systems out of the comfort zone, Earth and environmental scientists are increasingly being called on to address the big questions that affect all of us, like “How can we keep the planet habitable for humans?”. While the simple […]

China is burning (carbon) for you

Do not ask for whom China’s carbon burns, it burns for you! A new article in press at Energy Policy by Lin and Sun assesses the extent of carbon emitted to the atmosphere in China because of exports produced for consumption by other nations. While the exact contributions by exports are complex, and depend on economic sectors, as much as […]

Looking Back at the Cradle in the Rear-view Mirror

Are humans pushing earth systems towards environmental catastrophe? Or are we just worrying needlessly about the novel state of the earth that we have now created? Or both? In a Nature Feature entitled “A safe operating space for humanity” a team of scientists affiliated with the Resilience Alliance proclaim that “To avoid catastrophic environmental change humanity must stay within defined […]

Save the planet? From who?

Millennia ago, our species reshaped the ecology of this planet and we have continued to reshape it ever more rapidly and intensively ever since. Today, we directly use or alter nearly all of earth’s terrestrial ecosystems– the rest we alter indirectly through climate change. Is it still relevant to discuss “saving the planet”? If so, who or what is this […]

Globalization is good for the biosphere

Finally some good news about global change: globalization is making us cooperate! This is no minor discovery. Poverty, global warming, environmental degradation and biodiversity loss- all of these will only be solved when all of the people of all nations collaborate sustainably in doing so- though all these solutions must ultimately be local as well, because all global problems are […]
