Climate: Past, Present & Future

Are the risks of zoonotic diseases rising in the Anthropocene due to climate change?

The recent coronavirus outbreak (i.e., nCovID-19; Fig. 1) has caused global panic, along with widespread travel bans, home quarantines and country-wide lockdowns. The World Health Organization (WHO) declared nCoVID-19 as a pandemic as of March 11th, 2020 (WHO, 2020). To tackle this global health crisis, scientists are attempting to synthesize a vaccine, while countries are trying to mitigate the n ...[Read More]

The Dead Sea is dead. Nothing can live there except for specialized microbes. The water with a salinity multiple times higher than seawater prevents a colonization by higher life forms. However, it does not prevent the input of organic material that can tell us stories about the past. A unique sediment record The Dead Sea, located at the lowest elevation on Earth – currently about 430 m below sea ...[Read More]

Dear “climate sceptic”, do you have a fire insurance? – Climate policy under uncertainty

One often hears that ambitious climate policy might be premature while climate change is still “uncertain”. This sounds like a fair argument: The amount of global warming per doubling CO2 is not well constrained, and the amount of economic damage per degree of warming even less. But is this uncertainty a sound excuse to wait and see? Uncertainty, risk aversion, and insurance If you knew the ...[Read More]

Reconstructing past climate states from geological records is crucial for understanding the causal mechanisms that originated them. These can occur at time-scales which are much longer than the periods for which humans have been measuring climate variables such as temperature in meteorological stations. Such climate reconstructions provide a long-term context to the magnitude of the current anthro ...[Read More]
