update: Climate wars

Climate not to blame for African civil wars.

Vocal actors within policy and practice contend that environmental variability and shocks, such as drought and prolonged heat waves, drive civil wars in Africa. Recently, a widely publicized scientific article appears to substantiate this claim. This paper investigates the empirical foundation for the claimed relationship in detail. Using a host of different model specifications and alternative...

Update on Climate Change Climate Change: Resetting Plant-Insect Interactions

Elevated CO2 and temperature are altering the interactions between plants and insects with important implications for food security and natural ecosystems. Ecologically, the acceleration of plant phenology by warming is generating mismatches between plants and insect pollinators. Similarly, shifting the rate of plant development relative to insect development can amplify or minimize the consequ...

Geoengineering the climate: an overview and update.

The climate change that we are experiencing now is caused by an increase in greenhouse gases due to human activities, including burning fossil fuels, agriculture and deforestation. There is now widespread belief that a global warming of greater than 2(°)C above pre-industrial levels would be dangerous and should therefore be avoided. However, despite growing concerns over climate change and num...

Clone Wars

Code clones, the result of the ”copy&paste” programming technique, have negative impact on software quality and on the efficiency of the software maintenance process. Although copying may be the fastest way of creating a new feature, after a while it is really hard to detect and maintain the multiple instances of the same code snippets. Based on static source code analysis, clone detectors try ...
