The Morality of Manmade Climate Change...

Lawrence Torcello* has penned a very powerful statement about the moral dimension of manmade climate change in an opinion piece for the The Guardian. Here are the concluding paragraphs of his essay...

The climate policies of the Trump administration, backed by many Republican leaders, are rooted in culpable ignorance and transparent corruption. And they place us all at risk on a scale that previous crimes against humanity never have.

Civility and fair mindedness do not require hospitality to policies that hasten the destruction of a livable planet. We don’t depend on hindsight to recognize the moral gravity of our current situation.

We will search in vain for a better reason to depose elected officials. Every legal resource to remove such leaders is justified. We can’t pretend we don’t know the nature of what is unfolding. We are witnessing a crime against humanity – and the potential prelude to future genocide.

We are the bystanders who must choose to intervene or be defined by our failure.

Yes, I am a climate alarmist. Global warming is a crime against humanity, Opinion by Lawrence Torcello, Guardian, Apr 29, 2017

Extreme Arctic Melt Is Raising Sea Level Rise Threat; New Estimate Nearly Twice IPCC's

Global sea level rise could happen at nearly twice the rate previously projected by the U.N. Intergovernmental Panel on Climate Change, even under the best scenario, according to a new report.

By the end of this century, as some glaciers disappear completely, the Arctic's contribution to global sea level rise will reach at least 19 to 25 centimeters, according to the report by the Arctic Council's Arctic Monitoring Assessment Program (AMAP).

Factoring those numbers into projections about other sources of sea level rise results in a minimum of 52 centimeters of sea level rise by 2100 under a best-case scenario and 74 centimeters under business as usual. "These estimates are almost double the minimum estimates made by the IPCC in 2013," the authors wrote.

The report, called "Snow, Water, Ice and Permafrost in the Arctic 2017," takes a comprehensive look at the changes already underway in the Arctic, as well as what's in store. It was one of a handful of reports examining climate change in the Arctic and its effect on communities there that were released by AMAP in advance of this week's International Conference on Arctic Science and the Arctic Council ministerial in May, when the U.S. will hand off the Council chairmanship to Finland.

El Niño/La Niña Update 

There is a 50-60% chance of an El Niño event forming in middle to late 2017, according to a new Update from the World Meteorological Organization.

The El Niño/Southern Oscillation (ENSO) is a naturally occurring phenomenon involving fluctuating ocean temperatures in the central and eastern equatorial Pacific, coupled with changes in the atmosphere. It has a major influence on weather patterns in many parts of the world and has a warming impact on global air temperatures.

Following borderline weak La Niña/cool-neutral conditions during the second half of 2016, sea surface temperatures and most atmospheric fields returned to more ENSO-neutral levels in January 2017 that continued to the present.

Quote of the Week...

Calculating the costs of natural disasters is a valuable way for governments to recognize and limit the potential for damage, especially as extreme weather linked to climate change occurs more often, the United Nations' disaster prevention chief says.

Recent deadly landslides caused by floods in Peru and Colombia show the urgent need for governments to prepare better and invest more, said Robert Glasser, head of the U.N. Office for Disaster Risk Reduction (UNISDR).

"It's important to quantify the costs. As long as the costs of these disasters are invisible, it is very easy to ignore them, and it's very hard to make the case to spend money on prevention," he told the Thomson Reuters Foundation in an interview this week.

"It's about tying climate risk together with disaster risk more broadly and quantifying the costs historically and projecting future costs," he said.

SkS in the News...

In their article, Humans Caused 100% of the Past Century’s Global Warming, posted on Futurism, Karla Lant & Abby Norman wrote:

The overwhelming majority of scientists—about 97 percent—agree not only that climate change is happening, but that it is caused by humans. Nevertheless, most people don’t agree: they tend to disbelieve these kinds of statistics, or see climate change denial as an equally valid, “alternative” point of view.
