The Indian monsoon is likely to fail more often in the next 200 years, warns this new study by Jacob Schewe and Anders Levermann published in the journal Environmental Research Letters. Says that the monsoon rains could collapse about every fifth year between 2150 and 2200 with continued global warming.

Land use and land cover changes affect the partitioning of latent and sensible heat, which impacts the broader climate system. Increased latent heat flux to the atmosphere has a local cooling influence known as ‘evaporative cooling’, but this energy will be released back to the atmosphere wherever the water condenses. However, the extent to which local evaporative cooling provides a global cooling influence has not been well characterized. Here, we perform a

Generating energy from crops instead of oil and coal can have counterproductive effects. “The use of biomass can lead to additional emissions of greenhouse gases”, says lead author Alexander Popp of the Potsdam Institute for Climate Impact Research (PIK). “This is the case if forests get cut down to plant energy crops instead.” Forests are important CO2 sinks. At the same time, biomass is expected to play an important role in  future energy systems.

Expansion of global demand for soy products and biofuel poses threats to food security and the environment. One environmental impact that has raised serious concerns is loss of Amazonian forest through indirect land use change (ILUC), whereby mechanized agriculture encroaches on existing pastures, displacing them to the frontier. This phenomenon has been hypothesized by many researchers and projected on the basis of simulation for the Amazonian forests of Brazil.

Climate change will lead to significant changes of groundwater recharge and thus renewable groundwater resources. Using the global water resources and use model WaterGAP, the impact of climate change on groundwater recharge and the number of affected people was computed for four climate scenarios by two climate models. Vulnerability of humans to decreased

Climate change will affect urban workers the most, according to a study modelling the effects of climate change in 16 developing countries. The survey examined the potential economic influence of adverse climate events, such as heat waves, drought and heavy rains, on seven socioeconomic groups.

For millennia, India used surface storage and gravity flow to water crops. During the last 40 years, however, India has witnessed a decline in gravity-flow irrigation and the rise of a booming

To appropriately mitigate environmental impacts from transportation, it is necessary for decision makers to consider the life-cycle energy use and emissions. Most current decision-making relies on analysis at the tailpipe, ignoring vehicle production, infrastructure provision, and fuel production required for support. We present results of a comprehensive

As bottled water use continues to expand around the world, there is growing interest in the environmental, economical, and social implications of that use, including concerns about waste generation, proper use of groundwater, hydrologic effects on local surface and groundwater, economic costs, and more. A key concern is how much energy is required to produce and use bottled water.
