Climate change: things we can do

Climate Change or Land Use Dynamics: Do We Know What Climate Change Indicators Indicate?

Different components of global change can have interacting effects on biodiversity and this may influence our ability to detect the specific consequences of climate change through biodiversity indicators. Here, we analyze whether climate change indicators can be affected by land use dynamics that are not directly determined by climate change. To this aim, we analyzed three community-level indic...

Climate change: do we know enough for policy action?

The climate change problem must be thought of in terms of risk, not certainty. There are many well-established elements of the problem that carry considerable confidence whereas some aspects are speculative. Therefore, the climate problem emerges not simply as a normal science research issue, but as a risk management policy debate as well. Descriptive science entails using empirical and theoret...

Climate change and human health: what do we know?

Climate change. Can we detect trends in extreme tropical cyclones?

process may not have been so smooth as initially thought, and numerical simulations performed by Tsiganis et al. (4) show that the passage of Jupiter and Saturn through a 2:1 resonance may have ignited a period of strong chaotic evolution of Uranus and Neptune. In this scenario, the two planets had frequent close encounters and may even have exchanged orbits before their eccentricities finally ...

The economics of mitigating climate change: What can we know?

Article history: Received 22 June 2013 Received in revised form 28 January 2014 Accepted 28 January 2014 Available online xxxx The long-term economics of mitigating climate change over the long run has played a high profile role in the most important analyses of climate change in the last decade, namely the Stern Report and the IPCC's Fourth Assessment. However, the various kinds of uncertainti...
