New Accounting Method For Sources of Uncertainty

Climate scientists — including those of us at OCCRI and CIRC— use global climate models to understand the range of possible futures. Dozens of research groups produce hundreds of simulations, which may differ in their greenhouse-gas emission scenarios as well as their starting conditions for each simulation. Thus, interpretation can be challenging. Translating these simulations…

Connecting Causes and Impacts of Climate Change

Here’s what we know about climate change in a nutshell: Human influence on the climate system is clear Recent climate changes have had widespread impacts on human and natural systems Continued emission of greenhouse gases will cause further warming and long-lasting changes in all components of the climate system, increasing the likelihood of severe, pervasive…

Temperature Records Occur in Clusters

Studying the details of temperature fluctuations is essential to understanding how both individual organisms and whole ecoregions will adapt under climate change. But many studies could be missing an important nuance. Most studies examining long-term changes in temperature tend to focus on trends in the mean, or average temperature, as well as on the highest…
