When it comes to theories of societal collapse, apocalypse believers may have lost interest in the Maya, but scholars have not. Scientists, anthropologists, archaeologists, and historians continue to search for an explanation for the collapse of the Maya, which took place from approximately 800-1000 CE in a period known as the Terminal Classic.
A changing climate effects the availability of water, agriculture, and virtually everyone on the planet. To predict changes in vegetation cover and adapt water usage appropriately it’s necessary to constrain changes in evaporative flux. Measuring evaporation is more challenging than other components of the hydrologic
Research published in Science has highlighted the potentially deleterious effects of climate change on global food security. As defined by the United Nations’ Food and Agriculture Organization, food security has a number of components. These include food availability, access and utilization…
One frequently cited effect of climate change is the increased risk of flooding which could cause serious loss of life and property in many parts of the world. Areas including Southeast Asia, India, eastern Africa and the northern Andes are likely to be hit the hardest.
Global warming simulations suggest that wet regions (where precipitation exceeds evaporation) will become wetter and dry regions drier by the end of the 21st century (e.g., Held and Soden 2006), with larger contrasts expected between dry and wet seasons (Chou et al., 2013). This ‘rich-get-richer’ behavior is consistent with a large increase in the moisture content of atmosphere, leading to enhanced horizontal moisture fluxes across regions.
