Contributions of natural and anthropogenic forcing to changes in temperature extremes over the United States
[1] Observations averaged over the U.S. for the second half of the 20th century have shown a decrease of frost days, an increase in growing season length, an increase in the number of warm nights, and an increase in heat wave intensity. For the first three, a nine member multi-model ensemble shows similar changes over the U.S. in 20th century experiments that combine anthropogenic and natural f...
متن کاملHow will sea level respond to changes in natural and anthropogenic forcings by 2100?
[1] Using an inverse statistical model we examine potential response in sea level to the changes in natural and anthro‐ pogenic forcings by 2100. With six IPCC radiative forcing scenarios we estimate sea level rise of 0.6–1.6 m, with confidence limits of 0.59 m and 1.8 m. Projected impacts of solar and volcanic radiative forcings account only for, at maximum, 5% of total sea level rise, with an...
متن کاملAssessing Impact of Anthropogenic Disturbances on Forage Production in Arid and Semiarid Rangelands
Forage is one of the main products of rangeland ecosystems, which is threatened by different anthropogenic disturbances. This study was conducted to assess the impact of urbanization, rural development, agriculture extension, road construction and industry on forage production in an arid and semiarid rangeland using InVEST habitat quality model in spring 2018. In 14 rangeland types, thirty 2×1m...
متن کاملAuxiliary Material for: Estimated PDFs of climate system properties including natural and anthropogenic forcings
This auxiliary material provides additional information for Forest et al. (2005). It presents details on the methods used (Sect. 1) and a set of sensitivity tests for the estimated PDFs (Sect. 2). Three tests provide details on sensitivities to the noise model truncation, to the latitude dependence of the deep-ocean heat uptake, and to uncertainty in the volcanic forcing. There is also a sectio...
متن کاملEstimated PDFs of Climate System Properties Including Natural and Anthropogenic Forcings
We present revised probability density functions (PDF) for climate system properties (climate sensitivity, rate of deep-ocean heat uptake, and the net aerosol forcing strength) that include the effect on 20th century temperature changes of natural as well as anthropogenic forcings. The additional natural forcings, primarily the cooling by volcanic eruptions, affect the PDF by requiring a higher...
