Climigration? Population and climate change in Arctic Alaska
Residents of towns and villages in Arctic Alaska live on “the front line of climate change.” Some communities face immediate threats from erosion and flooding associated with thawing permafrost, increasing river flows, and reduced sea ice protection of shorelines. The term climigration, referring to migration caused by climate change, originally was coined for these places. Although initial applications emphasized the need for government relocation policies, it has elsewhere been applied more broadly to encompass unplanned migration as well. Some historical movements have been attributed to climate change, but closer study tends to find multiple causes, making it difficult to quantify the climate contribution. Clearer attribution might come from comparisons of migration rates among places that are similar in most respects, apart from known climatic impacts. We apply this approach using annual 1990–2014 time series on 43 Arctic Alaska towns and villages. Within-community time plots show no indication of enhanced out-migration from the most at-risk communities. More formally, there is no significant difference between net migration rates of at-risk and other places, testing several alternative classifications. Although climigration is not detectable to date, growing risks make either planned or unplanned movements unavoidable in the near future
River Discharge, in State of the Climate in 2008
The global mean temperature in 2008 was slightly cooler than that in 2007; however, it still ranks within the 10 warmest years on record. Annual mean temperatures were generally well above average in South America, northern and southern Africa, Iceland, Europe, Russia, South Asia, and Australia. In contrast, an exceptional cold outbreak occurred during January across Eurasia and over southern European Russia and southern western Siberia. There has been a general increase in land-surface temperatures and in permafrost temperatures during the last several decades throughout the Arctic region, including increases of 1° to 2°C in the last 30 to 35 years in Russia. Record setting warm summer (JJA) air temperatures were observed throughout Greenland
MAKING EFL INSTRUCTION MORE CLT-ORIENTED THROUGH INDIVIDUAL ACCOUNTABILITY IN COOPERATIVE LEARNING
This article attempts to add to the literature supporting Communicative Language Teaching (CLT) by proposing the use of Cooperative Learning (CL), specifically focusing on the enactment of a key principle of CL, i.e., individual accountability. It illustrates how to train students on CL and its individual accountability work and demonstrates how activities involved in individual accountability, i.e., individual students’ performance(s) and peer interaction, can accommodate the teaching of the four language skills and components. We argue that these activities promote learners’ use of and meaning making in English and thus recommend teachers, especially those new to CL, follow the procedure of CL techniques exactly as described so that language learning in their classrooms goes in the direction of attaining improved communicative competence—the goal of CLT.Â
