Climate change: It's time to talk, and act, tough

Climate change: It's time to talk, and act, tough

New "Old" Coal Plants Under Construction


Sixteen large coal-fired plants have fired up since 2008 and 16 more are under construction. These are old-style plants – they do not capture and sequester carbon dioxide. They will generate about 125 million tons of greenhouse gases annually, equivalent to putting 22 million additional automobiles on the road.

The expansion, the industry's largest in two decades, represents an acknowledgment that highly touted "clean coal" technology is still a long way from becoming a reality and underscores a renewed confidence among utilities that due in large part to their lobbying activities, proposals to regulate carbon emissions will fail.

A River Lost

‎
"This book is about the destruction of the great river of the West by well-intentioned Americans whose lives embodied a pernicious contradiction. They prided themselves on self-reliance, yet depended on subsidies. They distrusted the federal government, yet allowed it to do as it pleased with the river and the land through which it flowed. As long as there was federal money, they did not mind that farmers wasted water, that dams pushed salmon to extinction, or that plutonium workers recklessly spilled radioactive gunk beside the river" (Blaine Harden, A River Lost: The Life and Death of the Columbia).

This book is a must read for anyone in Eastern Washington who is at all suspicious of the Tea Party movement's rhetoric concerning big government.

The Climate is Changing and that Drives Other Changes

Pakistan Floods
Examples of observed climatic changes:
  • Increase in global average surface temperature of about 1°F in the 20th century
  • Decrease of snow cover and sea ice extent and the retreat of mountain glaciers in the latter half of the 20th century
  • Rise in global average sea level and the increase in ocean water temperatures
  • Likely increase in average precipitation over the middle and high latitudes of the Northern Hemisphere, and over tropical land areas
  • Increase in the frequency of extreme precipitation events in some regions of the world

Examples of observed physical and ecological changes:
  • Thawing of permafrost
  • Lengthening of the growing season in middle and high latitudes
  • Poleward and upward shift of plant and animal ranges
  • Decline of some plant and animal species
  • Earlier flowering of trees
  • Earlier emergence of insects
  • Earlier egg-laying in birds

In addition to the immediate human suffering brought on by these events, there will be dramatic food shortages stemming from the floods, fires, and heat that will extend the suffering over many years, and if we don't do something to mitigate the effects of anthropogenic, i.e., human caused, global warming (AGW), far into the foreseeable future.

An Enemy of the People

Dr. Thomas Stockmann is a popular citizen of a small coastal town. The town has recently invested a large amount of public and private money towards the development of medicinal baths, a project led by Dr. Stockmann and his brother, Peter Stockmann the Mayor. The town is expecting a surge in tourism and prosperity from the new baths, said to be of great health value, and as such, the baths are a source of great local pride.

Just as the baths are proving successful, Dr. Stockmann discovers that waste products from the town's tannery are contaminating the waters, causing serious illness amongst the tourists. He expects this important discovery to bring him honor and approval and promptly sends a detailed report to the Mayor, which includes a proposed solution, but one that would come at a considerable cost to the town.

To his surprise, Stockmann finds the authorities unwilling to accept the seriousness of the issue and to publicly acknowledge and address the problem, claming it could mean financial ruin for the town. As the conflict develops, Dr. Stockman’s own brother tells him he should "acquiesce in subordinating himself to the community." Dr. Stockmann refuses to accept this, and holds a town meeting in order to persuade people that the baths must be closed.

The townspeople - eagerly anticipating the prosperity that the baths will bring - refuse to accept Stockmann's claims, and his friends and allies, who had explicitly given support for his campaign, turn against him en masse. He is taunted and denounced as a lunatic, and an “enemy of the people."

Expert credibility in climate change: Who are the real experts and what do they think?

Russia, where 23 regions have declared a state of emergency due to drought.
 
ABSTRACT
Expert Credibility in Climate Change
Proceedings of the National Academy of Sciences (PNAS), April 9, 2010

Although preliminary estimates from published literature and expert surveys suggest striking agreement among climate scientists on the tenets of anthropogenic climate change (ACC), the American public expresses substantial doubt about both the anthropogenic cause and the level of scientific agreement underpinning ACC. A broad analysis of the climate scientist community itself, the distribution of credibility of dissenting researchers relative to agreeing researchers, and the level of agreement among top climate experts has not been conducted and would inform future ACC discussions. Here, we use an extensive dataset of 1,372 climate researchers and their publication and citation data to show that (i) 97–98% of the climate researchers most actively publishing in the field surveyed here support the tenets of ACC outlined by the Intergovernmental Panel on Climate Change, and (ii) the relative climate expertise and scientific prominence of the researchers unconvinced of ACC are substantially below that of the convinced researchers.
