IPCC

Scientists are grim, economists more optimistic about climate change's effects

The New York Times (March 13, 2009) reports from Climatewire (JEAN-MARIE MACABREY reporting) the results of the special IPCC meeting in Copenhagen.

Here is an excerpt:

"Scientists are gloomy; economists are more upbeat. Such was the bottom line of an epic, three-day international congress of climate change experts that ended here yesterday.

Rising sea levels set to have major impacts around the world

"Research presented today at the International Scientific Congress on Climate Change in Copenhagen shows that the upper range of sea level rise by 2100 could be in the range of about one meter, or possibly more. In the lower end of the spectrum it looks increasingly unlikely that sea level rise will be much less than 50 cm by 2100. This means that if emissions of greenhouse gases is not reduced quickly and substantially, even the best case scenario will hit low lying coastal areas housing one in ten humans on the planet hard.

Bali Declaration by Scientists

As is the case with the dozens of climate scientists who have support Lightblueline, scientists across the world are dismayed that their research results have not led to policy efforts in places like the United States. The time to act is now, and so a group of 200 scientists have signed the Bali Declaration to urge action by the UN and its members:

INTERVIEW-Greenland ice could be next puzzle for U.N. panel

Excerpt:
BALI, Indonesia, Dec 7 (Reuters) - A thaw of Greenland ice that could raise world sea levels may be the next puzzle for the U.N. climate panel that won the Nobel Peace Prize, a senior member of the group said.

U.N. report: Urgent action needed on 'severe' climate change

In its final report of the year, the IPCC issued its clearest warning to date about the need for real action really soon:
U.N. report: Urgent action needed on 'severe' climate change

Here are some excerpts from the CNN report on the IPCC report:
"Climate change is "severe and so sweeping that only urgent, global action" can head it off, a United Nations scientific panel said in a report on global warming issued Saturday.

Urgency

Urgency

The last two years have seen a remarkable turnaround in public perceptions of climate change, especially in the United States. Some critical threshhold seems to finally have been breached, and we see now that both the House of Representatives and Senate are at last considering meaningful legislative proposals to deal with the anthropogenic carbon dioxide emissions that are a major cause of warming. Al Gore’s movie, An Inconvenient Truth, was clearly an important catalyst for change. Another catalyst has been the release this year of the Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC: see www.ipcc.ch.) The IPCC was established in 1988 by the World Meteorological Association and United Nations Environment Programme, with a mission to assess the scientific basis for human-induced climate change, and to recommend policy options for what to do about the problem. The IPCC has released four comprehensive reports in its 19 year history, each sounding a successively more urgent warning about the impacts of fossil fuel burning on climate. Now, in its latest report, the IPCC states that most of the increase in temperature (about 0.7 °C or 1.3 °F since the start of the industrial revolution, with most of that increase in the last 40 years) is “very likely due to the observed increase in anthropogenic greenhouse gas concentrations.” In IPCC terminology, very likely means with greater than 90% probability. In 2001, the Third IPCC report had put the probability of human influence on climate at 67%. The new assessment, based on decades of intensive and increasingly sophisticated experimental observations and computer modeling, is the most authoritative statement yet, and has been a clear driver for the recent legislative initiatives. This is the good news.

Melting glaciers will dominate sea-level rise: New Scientist

On July 19th, Phil McKenna of the New Scientist newservice reported that recent estimates of near-term sea-level rise failed to capture the role of melting glaciers.
