Scenarios of future land use change around United States’ protected areas
|
Land use change around protected areas can diminish their conservation value, making it important to
predict future land use changes nearby. Our goal was to ev... |

Comment:Nuclear winter is a real and present danger
|
Models show that even a ‘small’ nuclear war would cause catastrophic climate change. Such findings must inform policy, says Alan Robock. |
