Committed warming and its implications for climate change

Nonlinear climate sensitivity and its implications for future greenhouse warming

Global mean surface temperatures are rising in response to anthropogenic greenhouse gas emissions. The magnitude of this warming at equilibrium for a given radiative forcing-referred to as specific equilibrium climate sensitivity (S)-is still subject to uncertainties. We estimate global mean temperature variations and S using a 784,000-year-long field reconstruction of sea surface temperatures ...

Equilibrium Climate Change - and its Implications for the Future

Talking about Climate Change and Global Warming

The increasing prevalence of social networks provides researchers greater opportunities to evaluate and assess changes in public opinion and public sentiment towards issues of social consequence. Using trend and sentiment analysis is one method whereby researchers can identify changes in public perception that can be used to enhance the development of a social consciousness towards a specific p...

Climate for Change: An Actuarial Perspective on Global Warming and its Potential Impact on Insurers

As the debate over global warming rages, actuaries may be able to play a greater role in evaluating the merits of the opposing views and contributing to climate research itself. Since hurricanes Hugo and Andrew, insurance companies have had to fundamentally rethink pricing, underwriting and financing for catastrophic weather-related coverage. Insurers also have had to consider whether these eve...

Indian Ocean warming modulates Pacific climate change.

It has been widely believed that the tropical Pacific trade winds weakened in the last century and would further decrease under a warmer climate in the 21st century. Recent high-quality observations, however, suggest that the tropical Pacific winds have actually strengthened in the past two decades. Precise causes of the recent Pacific climate shift are uncertain. Here we explore how the enhanc...
