Using Thoreau, scientists measure the impact of climate change on wildflowers — ScienceDaily

A new study is using observations made by Henry David Thoreau — 19th-century American naturalist, social reformer, and philosopher — to explore the effects of climate change on tree leaf-out and, as a result, the emergence of spring wildflowers.

Rainfall changes for key crops predicted even with reduced greenhouse gas emissions — ScienceDaily

By 2040, rainfall on wheat, soybean, rice and maize will have changed, even if Paris Agreement emissions targets are met; projections show parts of Europe, Africa, the Americas and Australia will be drier, while the tropics and north will be wetter.

Nations must triple efforts to reach 2°C target

Global emissions are on the rise as national commitments to combat climate change come up short. But surging momentum from the private sector and untapped potential from innovation and green-financing offer pathways to bridge the emissions gap. Those findings along with a sweeping review of climate action and the latest measurements of global emissions were presented by authors of the 2018 Emissions Gap Report.

Climate of North American cities will shift hundreds of miles in one generation

In one generation, the climate experienced in many North American cities is projected to change to that of locations hundreds of miles away — or to a new climate unlike any found in North America today. A new study and interactive web application aim to help the public understand how climate change will impact the lives of people who live in urban areas of the United States and Canada. These new climate analyses match the expected future climate in each city with the current climate of another location, providing a relatable picture of what is likely in store.

Moving artificial leaves out of the lab and into the air  

Researchers have proposed a design solution that could bring artificial leaves out of the lab and into the environment. Their improved leaf, which would use carbon dioxide — a potent greenhouse gas — from the air, would be at least 10 times more efficient than natural leaves at converting carbon dioxide to fuel.
