A ‘Third Way’ to Fight Climate Change

Two options for dealing with climate change — reducing greenhouse gas emissions through a global agreement, and geoengineering proposals such as injecting sulfur into the stratosphere — tend to dominate current thinking. But there is a “third way” that is almost entirely neglected in political negotiations and public debate. It involves capturing carbon dioxide from the atmosphere and storing it or using it to create things we need. Because of the scale of the climate problem, I believe that in coming decades third-way technologies will become a major focus of activity.

Cop21: il punto sugli INDCs

In negoziati internazionali sul clima di dicembre a Parigi (UNFCCC COP21) sono sempre più vicini. Le dichiarazioni di ottimismo sull’esito di un accordo globale (necessario a mantenere l’innalzamento della temperatura del pianeta al di sotto di 2 gradi centigradi) si alternano sempre più spesso al disincantato realismo di chi si limita ad osservare con preoccupazione gli impegni che i singoli paesi hanno assunto nei confronti della comunità internazionale.

U.S., China and Brazil Commit to New Climate Change Goals

The countries are positioning themselves as leaders ahead of December’s UN climate change conference. The United States, China and Brazil all made new commitments to combat climate change Tuesday, in advance of a landmark United Nations conference on the issue in December. The U.S. and Brazil pledged to increase production of electricity from renewable sources to represent 20% of electricity production by 2030. That’s three times as much renewable energy as the U.S. currently produces and twice as much as is produced in Brazil, according to the White House.

Pope Francis Aligns Himself With Mainstream Science on Climate

The new papal encyclical on the environment is a ringing call to action, a critique of consumerism and a prophetic warning about the dangers of ignoring what Pope Francis calls “the ecological crisis.” But amid all his soaring rhetoric, did the pope get the science right? The short answer from climate and environmental scientists is that he did, at least to the degree possible in a religious document meant for a broad audience. If anything, they say, he may have bent over backward to offer a cautious interpretation of the scientific facts.

G7, accordo sul clima: temperature globali entro il limite dei 2 gradi

C’è l’accordo sul clima fra i sette leader del G7 di Elmau: un’azione “urgente e concreta è necessaria per affrontare il cambiamento climatico”, hanno affermato i sette leader di governo nel comunicato finale. I capi di Stato si sarebbero accordati sul mantenere l’aumento della temperatura globale entro il limite di 2 gradi rispetto ai livelli preindustriali, su cui erano divisi fino a poco tempo fa. L’obiettivo prevede anche una riduzione dal 40% al 70% delle emissioni rispetto a quelle del 2010 entro il 2050, “nell’ambito di una risposta mondiale”.

Climate change could shrink Mount Everest’s glaciers by 70 percent

The iconic Mount Everest could see a major loss of its glaciers over the course of this century, according to a new scientific study that its chief author calls the “the first detailed modelling study of all glaciers in the Dudh Koshi basin in the Everest region of Nepal.”The paper, published Wednesday in the journal The Cryosphere, was authored by glacier researcher Joseph Shea of the International Centre for Integrated Mountain Development in Kathmandu, Nepal, and several colleagues from France and the Netherlands.
