Global warming: Of cattle and climate …

Efforts to reduce greenhouse gases should focus on livestock

FRISCO — Focusing on livestock to reduce greenhouse gas emissions could help humanity make some headway in the race to prevent catastrophic climate change, according to an international research team that took a close look at methane and nitrous oxide.

Cutting releases of methane and nitrous oxide, two gases that pound-for-pound trap more heat than CO2, should be considered alongside the challenge of reducing fossil fuel use, the scientists concluded in their analysis, published last week as an opinion commentary in Nature Climate Change, a professional journal.

“Because the Earth’s climate may be near a tipping point to major climate change, multiple approaches are needed for mitigation,” said Oregon State University forestry professor William Ripple. “We clearly need to reduce the burning of fossil fuels to cut CO2 emissions. But that addresses only part of the problem. We also need to reduce non-CO2 greenhouse gases to lessen the likelihood of us crossing this climatic threshold,” Ripple said. Continue reading

Global CO2 emissions rising unchecked

Co2 emissions are set to reach a record level this year.

New record level expected in 2013, with U.S. still by far the largest per capita source of greenhouse gases

By Summit Voice

FRISCO — Just in time for the Warsaw climate talks, climate trackers with the Tyndall Centre for Climate Change Research at the University of East Anglia said global carbon dioxide emissions are set to soar to a new record high of 36 billion tons in 2013 — 61 percent above the 1990 baseline levels set for the Kyoto Protocol.

“Governments meeting in Warsaw this week need to agree on how to reverse this trend. Emissions must fall substantially and rapidly if we are to limit global climate change to below two degrees. Additional emissions every year cause further warming and climate change,” said the Tyndall Centre’s Professor Corinne Le Quére, who led the global carbon budget report.

“Alongside the latest Carbon Budget is the launch of the Carbon Atlas, a new online platform showing the world’s biggest carbon emitters more clearly than ever before,” Le Quére said, explaining that China’s growing economy is driving the growth in greenhouse gas emissions. Continue reading

Climate: Global CO2 emissions to hit record high in 2012

U.S. still by far the largest per capita emitter of greenhouse gases

FRISCO — As delegates to the COP 18 climate talks in Doha, Qatar struggle to find agreement on basic issues — like how to account accurately for greenhouse gas emissions — the Global Carbon Project is reporting that carbon dioxide emissions will climb by 2.6 percent in 2012 to reach a record high of 35.6 billion tons in 2012.

The biggest contributors to global emissions in 2011 were China (28 per cent), the United States (16 per cent), the European Union (11 per cent), and India (7 per cent). Overall, 2012 emissions are now 58 percent higher than in 1990, the baseline year for targets set under the Kyoto Protocol. Continue reading

Global warming: Inching ahead at Bonn climate talks

SUMMIT COUNTY — Two weeks of climate talks in Bonn following up on the last year’s Durban summit didn’t yield much progress in some critical areas, although the delegates did take some steps toward finding a way to extend the Kyoto Protocol and on finding ways to help the most poor and vulnerable countries deal with global warming impacts.

The next round of climate talks is set for Doha, Qatar in November, when delegates are to decide on how long the extension of the Kyoto agreement should be, as an interim step before adopting a legally binding climate treaty in 2015.

The Doha meeting is also aimed at defining the precise emission reduction commitments of industrialized countries that have obligations under the Kyoto agreement.

United Nations climate officials tried to paint the Bonn talks in the best possible light, emphasizing the baby steps toward progress, while downplaying the fact that key players, particularly India and China, are balking. Continue reading

Global warming: Interim climate talks start in Bonn

Tough path ahead to implement Durban agreements

SUMMIT COUNTY — Global warming will once again take the center of the world political stage this week, with interim climate talks in Bonn, Germany, aimed at trying to nail down a few more details on agreements reached in principal at last December’s COP 17 in Durban.

The South African sessions ended with all countries, including China and India, agreeing that worldwide carbon reductions are needed. The hard part is how to get there. That’s what delegates will be discussing in Bonn this week. Continue reading

Global warming: COP17 Climate talks down to the wire

Draft deal targets legally binding agreement on emissions

SUMMIT COUNTY — Politics, economics and science clashed once again at the COP17 climate talks in Durban, but after a week of maneuvering and posturing, world leaders in the end did manage to draw up a document that once again acknowledges the threat of global warming and calls for renewed efforts to cut greenhouse gases.

The draft agreement released Friday calls for the “widest possible cooperation by all countries … with a view to accelerate the reduction of global greenhouse gas emissions.”

The agreement also expresses “grave concern” about the significant gap between promises and realities and aims to create a legally binding protocol that would commit countries to reducing greenhouse gas emissions. Continue reading

Global warming: 10 million Facebook votes wanted

Campaign targets action at  COP 17 in Durban

By Summit Voice

SUMMIT COUNTY — A new initiative launched in Germany this week aims to harness the power of social media, and Facebook in particular, to show world leaders that citizens of the world want action, and not just words, on climate change.

The Climate Vote Project website went live Aug. 15, steering people toward a Facebook page, where organizers are hoping get 10 million “Likes” by the time government ministers assemble in Durban, South Africa in late November for the COP 17 UN climate conference. Continue reading
