Want to Slow Climate Change? Stop Having Babies, Bioethicist Travis Rieder Says

And the world would be better off with fewer of them. That's a glib summary of a serious and seriously provocative book by Travis Rieder, a moral philosophy professor and bioethicist at Johns Hopkins University. When economists write about climate change, they'll often bring up something called the Kaya identity—basically a multiplication problem (not an espionage novel) that helps economists estimate how much carbon dioxide may be heading into the atmosphere. The Kaya identity says the pace of climate pollution is more or less the product four things: How carbon-heavy fuels areHow much energy the economy needs to produce GDPGDP per capitaPopulation. The Most Intelligent Bird On The Planet : Crow Talks Full Documentary. 90 companies are to blame for most climate change. Last month, geographer Richard Heede received a subpoena from Representative Lamar Smith (R-TX), chairman of the House of Representatives Committee on Science, Space, and Technology.

Smith, a climate change doubter, became concerned when the attorneys general of several states launched investigations into whether ExxonMobil had committed fraud by sowing doubts about climate change even as its own scientists knew it was taking place. The congressman suspected a conspiracy between the attorneys general and environmental advocates, and he wanted to see all the communications among them. Predictably, his targets included advocacy organizations such as Greenpeace, 350.org, and the Union of Concerned Scientists.

Neonic pesticide link to long-term wild bee decline. Climate models are accurately predicting ocean and global warming. For those of us who are concerned about global warming, two of the most critical questions we ask are, “how fast is the Earth warming?”

Climate models are accurately predicting ocean and global warming

And “how much will it warm in the future?”. The first question can be answered in a number of ways. For instance, we can actually measure the rate of energy increase in the Earth’s system (primarily through measuring changing ocean temperatures). India Man Plants Forest Bigger Than Central Park to Save His Island. India Has Planted Nearly 50 Million Trees In 24 Hours. The smoggy cities of India are suddenly looking a lot greener, with just under 50 million trees having been planted in India in a record-breaking attempt to raise awareness of conservation.

A global study, led by the University of Sussex, which included anthropologists and soil scientists from Cornell, Accra, and Aarhus Universities and the Institute of Development Studies has for the first-time identified and analysed rich fertile soils found in Liberia and Ghana. They discovered that the ancient West African method of adding charcoal and kitchen waste to highly weathered, nutrient poor, tropical soils can transform the land into enduringly fertile, carbon-rich black soils that the researchers dub ‘African Dark Earths’.

It's the end of the fossil fuel era as we know it. Contrary to what the fossil fuel industry may want you to believe, the transformation of the world's energy supply to clean energy sources is well underway, according to a new report from Bloomberg New Energy Finance (BNEF).

It's the end of the fossil fuel era as we know it

The "New Energy Outlook" report, released Monday, finds that at least $11.4 trillion will be invested in new power-generating capacity over the next 25 years, and 60 percent of that will fund wind and solar power. According to the report, we'll reach a tipping point in 2027, when new wind and solar power actually become cheaper than running existing coal and gas generators in much of the world.

This will cause an acceleration in the deployment of clean energy technologies. According to the report, new wind and solar may become cheaper than running existing coal and gas generators by 2027. To meet that goal, an additional $5.3 trillion in new clean energy investment worldwide would be needed during the next 25 years. The BNEF report contains several key predictions.
