New economic and philosophical research argues that policymakers must consider both the beneficial effects of climate change to “climate winners” as well as its costs in order to appropriately incentivize actions that are best for society and for the environment.
Researchers at Princeton University and the University of Miami found that the latest generation of high-sensitivity climate models do not provide a plausible scenario of Earth’s future climate. These models project that clouds moderate greenhouse gas-induced warming — particularly in the northern hemisphere — much more than climate records show actually happens. The results provide a cautionary tale on interpreting climate simulations, which can determine the aggressiveness of carbon-mitigation policies.
The models used to produce global climate scenarios may overestimate the energy and emission savings from improved energy efficiency, warns new research led by academics at the University of Sussex Business School and the University of Leeds.
New research by Newcastle University has shown that warming temperatures in some regions of the UK are the main drivers of increases in extreme short-duration rainfall intensities, which tend to occur in summer and cause dangerous flash flooding.
Carbon taxes are cheaper, more efficient than other policies, study finds
The landmark 2015 Paris Agreement resulted in multiple studies examining the impact of global temperature increases, but these rarely investigate the effect of warming on “fire weather” conditions. Now, in a new study, scientists have found that by projecting two different types of fire weather conditions, an additional half-degree of warming could drastically increase the likelihood and significance of blazes worldwide.

Gender influences how people experience and respond to climate change. This is particularly evident in developing nations where women and men adapt to climatic shocks differently. Women work harder and longer, in poorer conditions, while men are more likely to migrate to find work that’s often insecure and unreliable.

Greg Hunt’s “fact checking” for vaccine misinformation should be copied by the energy department. But they’d be flat out checking their minister’s own declarations.

Although the use of pesticides in agriculture is increasing, some farms have transitioned to organic practices and avoid applying them. But it’s uncertain whether chemicals applied to land decades ago can continue to influence the soil’s health after switching to organic management. Now, researchers reporting in ACS’ Environmental Science & Technology have identified pesticide residues at 100 Swiss farms, including all the organic fields studied, with beneficial soil microbes’ abundance negatively impacted by their occurrence.
