Different lines of evidence suggest that divergence in plasticity plays a key role in adaptation to global environmental change. Many scientists argue that genetic variation in plastic responses to the environment (G × E) could be an important predictor of species' vulnerabilities to climate change. But there is not a general pattern among either experimental or theoretical studies. Plasticity acting at the level of the individual is considered a rapid mechanism for surviving under rapidly changing conditions. But plasticity can also retard adaptation by shifting the distribution of phenotypes in the population, shielding it from natural selection. We know that not all plastic responses are adaptive. I will illustrate some examples of ecological traps, and, for the case of plants, the paradoxical decision regarding roots that we are far from understanding and modelling. Plasticity may buy time for populations, but whether it will be enough, given the rate of environmental change, is unknown.
Sea-level rise represents one of the main impacts of climate change. Globally, low elevation coastal areas represent 2% of the surface area, but account for 10% of the world's population and many of the economic assets and infrastructures. Moreover, the increase in sea level causes extreme values occur more frequently, affecting the exposed communities and assets (environmental and economic) more severely. This also generates an increase in the erosion rate, increasing the recoil of the coastline, which in turn makes the coastal and active resources located there much more exposed. In this context, it is essential to understand current and future risks and a number of studies show the need to adapt the format of the information to the agents who need to make decisions on adaptation.
