“I take every opportunity to clean up,” says Ron Milo, seen here with a helper as they collect trash along a trail. “It fills me with joy ... Our call is for people to take responsibility.”
There is always a flurry of environmental awareness activity around this time of year, with Earth Day and spring both making us more tuned in to our world. But being tuned in can be dispiriting, thanks to the relentless drumbeat of bad environmental news.

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.

Everything is connected: pharmaceuticals can be found throughout the environment. Fish seem particularly susceptible. Plus, we eat them – and, thus, consume whatever drugs are in their bodies.
Billions of us take medications on a regular basis, and while they help manage common conditions like viruses, depression, pain, menopause, thyroid disease, and the like, they are not so good for the environment.

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.

REHOVOT, ISRAEL—March 14, 2019—Antifreeze is life’s means of surviving in cold winters: natural antifreeze proteins help fish, insects, plants, and even bacteria live through low temperatures that should turn their liquid parts into deadly shards of ice. Strangely enough, in very cold conditions, the same proteins can also promote the growth of ice crystals. This was the finding of experiments carried out in Israel and Germany using proteins taken from fish and beetles. The results of this study, recently published in The Journal of Physical Chemistry Letters, could have implications for understanding the basic processes of ice formation.

‘Since I work on rubisco I’m always giving talks saying that it is the most abundant protein on Earth. Sometimes my audience will ask “Are you really sure?” I can now say “Yes I am”.’ This is how Manajit Hayer-Hartl from the Max Planck Institute of Biochemistry, Germany sums up her thoughts on a new analysis that the global abundance of plants’ carbon dioxide converting enzyme is an order of magnitude higher than thought.
Sep 01, 2019... Among the many ongoing changes inflicted on our climate and atmosphere, the increase in CO2 level has been the most consistent, with about 1.5-2 ppm annual increase. CO2 is the substrate for plant photosynthesis, and hence the expectation that the more CO2 we emit to the air, the more CO2 is available for plant growth. Indeed, CO2 fertilization has been used successfully to increase yields in greenhouses. Yet, in the majority of scenarios outside the greenhouse, plant growth is limited by other factors, such as light, water, and nutrients. Therefore, so far, global crop yields have not benefitted from surplus CO2.

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.

Prof. Dan Yakir
The Weizmann Institute’s Prof. Dan Yakir has won this year’s Israel Prize for Research in Geology, Earth Sciences and Atmospheric Sciences, for his groundbreaking insights into the impact of semi-arid forests on the global climate.
“At the station he founded in the Yatir Forest, Prof. Yakir explores the interactions between the biosphere and the atmosphere, especially the ways in which vegetation influences the environment and the climate,” Education Minister Naftali Bennett tweeted.

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.
