Climate change: a creeping catastrophe.
Q: People often blame unseasonal weather on climate change. Could you please explain the difference between weather and climate? A: Weather is what we see hourto-hour and day-to-day, and weather forecasts can tell us if it will rain, say, tomorrow afternoon, but because the weather is innately chaotic, forecasts for longer than 10 days are extremely poor. Climate is different. It is an average ...
متن کاملTidal Venuses: triggering a climate catastrophe via tidal heating.
Traditionally, stellar radiation has been the only heat source considered capable of determining global climate on long timescales. Here, we show that terrestrial exoplanets orbiting low-mass stars may be tidally heated at high-enough levels to induce a runaway greenhouse for a long-enough duration for all the hydrogen to escape. Without hydrogen, the planet no longer has water and cannot suppo...
متن کاملClimate Change Skepticism in the Face of Catastrophe
Despite overwhelming scientific evidence for man-made climate change, many people and more importantly policymakers still remain skeptical about the subject. While this phenomenon of ”climate-skepticism” prevents implementation of environmental policies around the globe, it is ignored in economic models of climate change. In this paper we fill this gap by creating a model that allows for climat...
متن کاملClimate change in Australian tropical rainforests: an impending environmental catastrophe.
It is now widely accepted that global climate change is affecting many ecosystems around the globe and that its impact is increasing rapidly. Many studies predict that impacts will consist largely of shifts in latitudinal and altitudinal distributions. However, we demonstrate that the impacts of global climate change in the tropical rainforests of northeastern Australia have the potential to re...
متن کاملSoldiers and Oil Well Smoke
have to be considered. The first, which has been developed in the preceding section, is that passive smoking could act to disclose an asthmatic state that was so far asymptomatic. The second issue lies in the natural history of asthma. Following Martinez et al.’s publications, it has become obvious that transient wheezing could occur in non-atopic infants exposed to passive smoking. Because the...
