▶ Arctic Sea Ice Has Declined Steeply Since 1979 | Video - LiveScienceVideos

Published on Jan 14, 2015
NASA data shows that average sea ice totals have dropped significantly, with a precipitous fall between 2002 and 2008. Sea level rise is a direct result of sea ice loss.

Threshold cascades with response heterogeneity in multiplex networks

Threshold cascades with response heterogeneity in multiplex networks | Climate Adaptation | Scoop.it
Threshold cascade models have been used to describe the spread of behavior in social networks and cascades of default in financial networks. In some cases, these networks may have multiple kinds of interactions, such as distinct types of social ties or distinct types of financial liabilities; furthermore, nodes may respond in different ways to influence from their neighbors of multiple types. To start to capture such settings in a stylized way, we generalize a threshold cascade model to a multiplex network in which nodes follow one of two response rules: some nodes activate when, in at least one layer, a large enough fraction of neighbors is active, while the other nodes activate when, in all layers, a large enough fraction of neighbors is active. Varying the fractions of nodes following either rule facilitates or inhibits cascades. Near the inhibition regime, global cascades appear discontinuously as the network density increases; however, the cascade grows more slowly over time. This behavior suggests a way in which various collective phenomena in the real world could appear abruptly yet slowly.

Global Warming Threatens Organic Coffee ("from coconuts to coffee, fungi infests plants worldwide")

Global Warming Threatens Organic Coffee ("from coconuts to coffee, fungi infests plants worldwide") | Climate Adaptation | Scoop.it
Global warming has created the worst outbreak of leaf-rust fungus in 30 years for organic

Farmers can use chemicals to kill the fungus, though they risk losing their organic certification if they do.

Humid conditions and erratic weather for the past two years in Chiapas, Mexico, have allowed the fungus spores to spread much faster than in the past, according to Ruben Bernabe of the Chiapas Federation of Ecologic Indigenous Coffee Producers. The fungus is expected to reduce the crop — both organic and non-organic — by 23 percent this year from 2013, according to local government data.

In Guatemala, the fungus used to only be a threat to coffee plants grown below 3,000 feet. Now the fungus is hitting crops as high as 6,000 feet.

In Colombia, leaf rust devastated crops from 2009 to 2012, which sent prices for the beans to a 14-year high in 2011.

The disease, first found in Latin America in the 1970s, is caused by the fungus Hemileia vastatrix, which disrupts photosynthesis and prevents beans from reaching full maturity.

According to Steve Savage, a plant pathology consultant in Encinitas, Calif., farmers can kill the fungus by using a copper-based fungicide. However, the fungicide can wash off the plants in wet weather, requiring the workers to apply it every few days. This increases the amount that runs off into streams, which can endanger wildlife, and potentially poison soil.

In 2012, researchers at Britain’s Royal Botanic Gardens at Kew and scientists in Ethiopia warned that wild Arabica coffee could be extinct in 70 years due to rising temperatures as a result of climate change.

We may end up drinking chemically-laced coffee from our brewer.

"Global warming has created the worst outbreak of leaf-rust fungus in 30 years for organic coffee growers throughout Mexico, Central America and parts of South America, according to Bloomberg.

"Farmers can use chemicals to kill the fungus, though they risk losing their organic certification if they do. ...

"According to a report last year from the United Nations Intergovernmental Panel on Climate Change, global warming is “unequivocal” and each of the last three decades has been warmer at the Earth’s surface than any previous decade since 1850."

30,000-year-old Yukon bison bone yields new clues on climate-change adaptation

[excerpt]

A 30,000-year-old bison bone plucked from the thawed permafrost inside a Yukon gold mine has helped a team of Australian scientists make a potentially groundbreaking discovery about the way animals adapt to climate change.

A study published in the latest issue of the journal PLoS One describes the Canadian specimen — a bone from the extinct steppe bison, an ancient buffalo that disappeared at the end of the last ice age — as key to unravelling a mystery about how "epigenetic" DNA adjustments can occur more rapidly than full-scale genetic changes in an ecologically stressed species.

The team of six researchers, including scientists from the Australian Centre for Ancient DNA at the University of Adelaide, made their "world-first" findings by probing genetic markers from the remains of six steppe bison specimens unearthed at the Yukon mine.

One of the bison bones produced high-resolution evidence that epigenetic modifications — the switching on or off of genes, without altering a species' fundamental DNA sequence — were occurring in the steppe bison during the Pleistocene era, when woolly mammoths and other megafauna were vanishing from their Arctic and sub-Arctic habitats.

"These 'epigenetic' changes can occur rapidly between generations — without requiring the time for standard evolutionary processes," states a summary of the research.

To reach their conclusions, the Australian team compared the bison bone to other genetic material drawn from a 30-year-old mummified cow from New Zealand and various modern cattle.

Making your living from the land in Australia is not for the faint-hearted. Isolation, hard physical work, long hours and the vagaries of drought, floods and fire make it a challenging environment for any farmer. But how do you cope when you are a woman in what is traditionally a man’s world?

Density games

Density games | Climate Adaptation | Scoop.it
The basic idea of evolutionary game theory is that payoff determines reproductive rate. Successful individuals have a higher payoff and produce more offspring. But in evolutionary and ecological situations there is not only reproductive rate but also carrying capacity. Individuals may differ in their exposure to density limiting effects. Here we explore an alternative approach to evolutionary game theory by assuming that the payoff from the game determines the carrying capacity of individual phenotypes.

PUBLICATION: Climate change adaptation in fisheries and aquaculture – compilation of initial examples

PUBLICATION: Climate change adaptation in fisheries and aquaculture – compilation of initial examples | Climate Adaptation | Scoop.it

Abstract

 

This circular contains a selection of current and recent climate change adaptation activities and measures in the fisheries and aquaculture sector. These examples provide an overview of the types of adaptation activities and programmes rather than a comprehensive review of adaptation activities addressing fisheries and/or aquaculture. Some of the highlighted activities are specifically targeted at addressing climate change impacts in fisheries or aquaculture, and others address related areas (e.g. coastal management and capacity building activities) that also have benefits for fisheries or aquaculture. In addition to specific examples, the publication provides an overview of climate change impacts on global fisheries and aquaculture and potential adaptation and mitigation strategies.

 

Descriptions for 26 current or recent activities and programmes focused specifically on or benefiting fisheries and/or aquaculture (and other sectors if relevant), primarily in developing countries, highlight the diversity of potential adaptation actions at the local to regional scales. This circular is intended to provide a starting point for planners, policy-makers and practitioners who are involved in sectors related to fisheries and aquaculture around the globe.
