Using a multivaritate probabilistic model, we quantify the average annual yields of major rainfed crops in Australia as a function of precipitation and soil moisture indices during the growing season. In the period 1980-2012, yields were 25–45% lower in dry seasons.

Jacobson et al. argue that wind, solar and hydro power alone could meet all U.S. energy demands at "low-cost." Unfortunately, their work contains errors, incorrect and unsupported assumptions, and inappropriate methods. It's possible to get all our energy from renewables, but Jacobson et al. haven't proven it'll be reliable or affordable.

We show that small increases mean temperatures may lead to big increases in heatwave deaths in India. For example, if summer mean temperatures increase by 0.5 °C, the chances of a heatwave that kills >100 people goes from roughly 1 in every 8 years to 1 in 3 years.

With its growing population, industrializing economy, and large coal reserves, India represents a critical unknown in global projections of future CO₂ emissions. As of mid-2016, proposed coal-fired power plants in India are incompatible with its NDC to reduce carbon intensity 33-35% by 2030.

In a groundbreaking interdisciplinary analysis, we quantify the global links among consumption of goods and services, production of air pollution, atmospheric transport of that pollution, and human mortality due to the pollution. We find that roughly a quarter of air pollution deaths are related to goods produced in one world region for consumption in another.
