Jennifer Francis: Wacky Weather and disappearing Arctic Sea Ice are they connected?

Dr. Jennifer Francis – Rutgers University “Extreme weather events are increasing in frequency and intensity all around the northern hemisphere.” Concurrently, Arctic sea ice is in an accelerating decline, the entire surface of Greenland melted for the first time in at least 150 years, glaciers are disappearing around the world, and snow cover on Arctic…

The Dunning-Kruger Effect

In the field of psychology, the Dunning–Kruger effect is a cognitive bias in which people of low ability have illusory superiority and mistakenly assess their cognitive ability as greater than it is. The cognitive bias of illusory superiority comes from the inability of low-ability people to recognize their lack of ability. Without the self-awareness of metacognition, low-ability people cannot objectively evaluate their competence or incompetence.  http://en.wikipedia.org/wiki/Dunning%E2%80%93Kruger_effect •••••••• PERCENTILES.…

The Psychological Impacts of Global Climate Change

Authors: Doherty, Thomas J.; Clayton, Susan An appreciation of the psychological impacts of global climate change entails recognizing the complexity and multiple meanings associated with climate change; situating impacts within other social, technological, and ecological transitions; and recognizing mediators and moderators of impacts. This article describes three classes of psychological impacts: direct (e.g., acute or…

Fires, Floods, and Heavy Snow: an Extreme May Weather Situation

Dr. Jeff Masters / via Wunderground – A highly unusual jet stream pattern is bringing a bizarre combination of heavy May snows, flooding, extreme fire danger, and well below average severe thunderstorm activity to the U.S. A strong “blocking” high pressure system has set up over Greenland, blocking the normal west-to-east progression of weather systems. A truly unusual situation has developed…

NASA: Warming-Driven Changes in Global Rainfall

By Kathryn Hansen NASA Goddard Space Flight Center. A NASA-led modeling study provides new evidence that global warming may increase the risk for extreme rainfall and drought. Model simulations spanning 140 years show that warming from carbon dioxide will change the frequency that regions around the planet receive no rain (brown), moderate rain (tan), and very heavy…
