Pollution’s impact on weather, crops worse than once thought
By ISRAEL21c Staff
New multinational research reveals that even small amounts of manmade aerosol particles can wreak havoc.
Even the tiniest of particles from human emissions can fuel powerful storms and influence weather and crops much more than previously thought, according to new research published January 26 in the journal Science.
The study focuses on the power of manmade aerosol emissions to grow rain clouds and intensify storms. These particles come from urban and industrial air pollution, wildfires and other sources.

Yam Pro Energy and India’s Shapoorji Pallonji Group will build a commercial-scale wave-power station in Ghana to serve 10,000 households.
Israel’s Yam Pro Energy signed a partnership with Indian business conglomerate Shapoorji Pallonji (SP) Group to begin production on the world’s first commercial-scale wave energy power station in Ghana.
The $180 million station, located along the coastline near the capital city of Accra, will be designed to generate up to 150 megawatts.
New paint transforms sun’s rays into cool air-conditioning
By Abigail Klein Leichman for Israel21c
SolCold’s nanotech coating is a potentially game-changing electricity-free solution for cooling buildings or equipment in intensely sunny climates.
Coating materials that protect against fire, water or extreme temperatures are nothing new. But an Israeli high-tech paint doesn’t just protect surfaces from the sun. SolCold actually uses the sun’s power to activate a cooling mechanism, effectively providing air conditioning without electricity.
You read that right: This double-layered coating absorbs the hot rays of the sun and re-emits that energy in the form of cold. The hotter the solar radiation the more the coating cools down, making SolCold’s paint a potentially game-changing electricity-free solution for intensely sunny climates such as Africa and Central and South America.
Happy Tu Bishvat, the new year for trees
RUSSELL MCLENDON for MotherNatureNetwork
The ancient holiday has become like a 'Jewish Arbor Day' in modern times, bringing religious and secular observers together for ecological reflection.
This spring will mark the 142nd anniversary of Arbor Day, founded in April 1872 as a time to "plant, nurture and celebrate trees."
But long before that, another tree-centric holiday had already been promoting arboreal appreciation for centuries. Tu Bishvat — also spelled Tu B'Shvat, Tu B'Shevat or Tu BeShvat — is an ancient Jewish holiday known as the "new year for trees." Its original role was to calculate the age of fruit trees, but today it has a broader ecological tone, earning it nicknames like "Jewish Arbor Day" and even "Jewish Earth Day."
Tu Bishvat falls on Jan. 31 this year (it technically begins at sunset Jan. 30), marking one of four new years on the Jewish calendar. While many religious and secular observers honor the holiday by planting trees, it has also inspired lots of other eco-friendly traditions over the years, from sustainable seders to tree-sitting.

Is that food really fresh? Find out at a glance
By Brian Blum for Israel21c
An Israeli company is marketing its intelligent date code labels that monitor the temp and time interval of food products on their way to consumers.
“The milk is past its expiry date. We have to throw it out.”
“No, we don’t. It smells fine.”
“But it says so right on the carton.”
It’s an argument that’s been heard in households around the world: Does the expiration date on the package really mean the milk or the chicken or the eggs are bad?
