چکیده
Le climat de la terre change, mais le taux de changement et ses effets indirects est loin de comprendre et largement débattu. Écarts de jusqu'à 5 ° c peuvent être vu entre les modèles de prévision climatique rend difficile pour les responsables politiques à prendre les mesures nécessaires pour atténuer et s'adapter à un réchauffement de la planète terre. Les observations globales de la terre par satellite sont le seul moyen de fournir la date nécessaire pour améliorer la fidélité des prévisions et en particulier de contraindre et de les tester. Ces données doivent être collectées décennies permettant aux petites tendances à être détecté issu d'un milieu de variabilité naturelle-mise des exigences sévères sur la performance des capteurs satellite. À présent peu si les satellites sont en mesure de livrer vraiment mesures traçables SI de l'orbite et zéro avec l'incertitude nécessaires pour les études climatiques à long terme, qui est proche de celle uniquement réalisables à l'aide d'étalons primaires en laboratoire. Le livre décrit une mission proposée par satellite conçue pour tirer le prima...

متن کاملNatural Disturbance effects on forest carbon dynamics, and the role of forest management in the process
Natural disturbance processes are affected by both forest management and climate change. The resulting shifts in natural disturbance processes can have profound impact on the secondary successional pathways of British Columbia forest types (Ran & Swift 2013). Building an understanding of how these systems work and their potential changes over time and space is important since many forest manage...
