A novel approach for selecting extreme climate change scenarios for climate change impact studies

Selecting global climate models for regional climate change studies.

Regional or local climate change modeling studies currently require starting with a global climate model, then downscaling to the region of interest. How should global models be chosen for such studies, and what effect do such choices have? This question is addressed in the context of a regional climate detection and attribution (D&A) study of January-February-March (JFM) temperature over the w...

Uncertainty Investigation of Precipitation and Temperature Scenarios for the Sira Basin under Climate Change Impact

Results of assessment of the future climate change impacts is associated with some uncertainties. Considering the range of uncertainties increases reliability of the results. In this study, climate change impacts on daily precipitation, maximum and minimum temperature of Sira basin are assessed using LARS-WG model, for 2036-65 period. Accordingly, uncertainty of new emissions scenarios (RCP2.6،...

Selecting climate simulations for impact studies based on multivariate patterns of climate change

In climate change impact research it is crucial to carefully select the meteorological input for impact models. We present a method for model selection that enables the user to shrink the ensemble to a few representative members, conserving the model spread and accounting for model similarity. This is done in three steps: First, using principal component analysis for a multitude of meteorologic...

Selecting regional climate scenarios for impact modelling studies

New climate change scenarios

whaling in the Southern Ocean is problematic. " The Japanese are still out catching fairly significant numbers of whales, and not just minkes, though that's what they're meant to be focusing on, " he commented. " If they stuck to their targets, and did their whaling as they say they do when they're at the IWC meetings, then I think they might have a little more support. They'd also need to do t...
