Executive summary
The proliferation of offensive cyber capabilities (OCC) the combination of tools; vulnerabilities; and skills, including technical, organizational, and individual capacities used to conduct offensive cyber operations presents an expanding set of risks to states and challenges commitments to protect openness, security, and stability in cyberspace. As these capabilities become more prolific, their regulation through formal international norms and export controls is increasingly ineffective. Countering the spread of dangerous capabilities is not a new policy challenge, but its specific application to the cyber domain remains uncertain both in theory and in practice. Left unc ....

Critical temperature for tropical tree lifespan revealed

Credit: Roel Brienen
For the first time scientists have provided clear evidence that tropical tree lifespan decreases above a critical temperature threshold.
Findings, published today (14 December) in the journal
PNAS (Proceedings of the National Academy of Sciences) show that across the tropics, tree lifespans decrease for temperatures above 25 C.
As temperatures are rising rapidly across large parts of the tropics, tree mortality is likely to accelerate in substantial parts of the tropics, including the Amazon, Pantanal and Atlantic forests with implications for animal habitats, air quality and carbon stocks.
Although tropical rainforests account for only 7% of all land, they are home to about 50% of all animal and plant species, and approximately 50 % of forest carbon stocks on earth. Thus small changes in the functioning of tropical forests can significantly change the atmospheric levels of CO2 - the most important anthropogenic greenhouse gas. ....
