Our new world order is particularly brutal for trees. Between climate change and economic greed, these lifegiving – and lifesaving – plants are not doing so well.
Besides well-known, large-scale devastations such as wildfires and deforestation (particularly of the Amazon, whose mighty forests are the reason the region is called – for now, anyway – the lungs of the planet), incremental changes are wreaking quieter, though no less devastating, impacts; for example, species native to the American South can no longer survive the warmer climate and so are spreading into cooler Northern climes. Behind them comes desertification.

May 31, 2019... The first time The Curiosity Review saw a picture of the new cloud type asperitas, it looked so much like the definition of “forbidding” that we thought it had to be fake. It was spring 2017, and there was news of a citizen-science group’s success in convincing the World Meteorological Organization to add asperitas to the august International Cloud Atlas. Ten other new cloud types were also added – the first since 1975 – in large part due to the efforts of that group, the Cloud Appreciation Society.

No matter where in the world you are right now, odds are you’ve recently experienced severe storms. And if you feel like they’re becoming more common, you are correct: more frequent, more severe storms are one of the many devastating effects of global warming. This makes sense, given that storms are how the earth gets rid of heat.

It’s the height of summer – time to hit the beach, whether for an afternoon or a week or two. People love the ocean and have always been drawn to it, but as much as it affects us, we affect it, too.
The ocean's health is crucial to the planet’s health – and ours. That’s why the devastating impacts from climate change are so concerning: as the temperatures warm, glaciers melt, and seawater becomes more acidic, as fish and mammals are overfished, the oceans are dying.

Farmers in arid areas of India need no convincing that the climate is changing under their feet. Their income is drying up along with their groundwater wells, forcing many to give up farming.
As these kinds of situations become more common, help is coming from Tel Aviv University's Nitsan Sustainable Development Lab directed by Ram Fishman, an expert on smallholder farmers and climate change.
His team assesses agriculture, water and energy problems in rural Asia and Africa and finds Israeli technologies to solve them.

Even with growing awareness of climate change, global greenhouse gas emissions are still climbing. And, in recent years, scientists have worked to apply advances in synthetic biology — the the application of engineering principles to the study of organic life — toward some of our most pressing environmental challenges.
Nov 27, 2019... REHOVOT, ISRAEL—November 27, 2019—Bacteria in the lab of Prof. Ron Milo of the Weizmann Institute of Science have not just sworn off sugar – they have stopped eating all of their normal solid food, existing instead on carbon dioxide (CO2) from their environment. That is, they were able to build all of their biomass from air. This feat, which involved nearly a decade of rational design, genetic engineering, and a sped-up version of evolution in the lab, was reported in Cell. The findings point to means of developing, in the future, carbon-neutral fuels.
Oct 31, 2019... The ocean is one of the largest and most mysterious ecosystems on Earth. In the tenth episode of Weizmann in Focus, Dave Doneson describes the fascinating research of Weizmann Profs. Ilan Koren and Assaf Vardi who set sail aboard the Tara schooner to unlock some of these mysteries. They were among a select group of scientists who traveled thousands of kilometers across all the world’s oceans to advance research and increase environmental awareness. The research conducted on board the schooner yielded hundreds of scientific papers as well as a better understanding of the ocean ecosystem and how it impacts the entire planet.

California's giant Sequoias can live for more than 3,000 years, their trunks stretching two car lengths in diameter, their branches reaching nearly 300 feet toward the clouds. But a few years ago, amid a record drought, scientists noticed something odd. A few of these arboreal behemoths inside Sequoia and Kings Canyon National Parks were dying in ways no one had ever documented—from the top down.
When researchers climbed into the canopies, they discovered that cedar bark beetles had bored into a few branches. By 2019, at least 38 of the trees had died—not a large number, but “concerning because we’ve never observed this before,” says Christy Brigham, the park’s chief of resource management.

Finally, some positive news about climate change: Even small groves in your backyard or city park help fight the effects of rising temperatures, drought and greenhouse gases.
“Urban orchards and green spaces can contribute to a range of ecosystem services,” writes Weizmann Institute of Science postdoctoral researcher Rafat Qubaja in a soon-to-be-published paper.
Those “services” include storing carbon, reducing air pollution, regulating the urban microclimate, cooling and shading, retaining rainwater and soil moisture, recharging groundwater and more.
