    It's Hot Outside. Could This Machine be the Answer to Global Warming?

    It's hot outside – and getting hotter. <em>The Times of Israel</em> examines whether Weizmann's Prof. Jacob Karni might have developed a solution, saying that he and ""an entrepreneur have patented a device that extracts carbon dioxide from the atmosphere and turns it into fuel. They say it has the potential to save life on our planet.""

    Microbes Go, Too: ""Fecal Prints"" Provide Record of Life on Earth

    If it eats, it excretes – including microbes. Having digested organic matter on Earth for about 3.5 billion years, their waste contains a record of how our environment has changed. However, no one has been able to interpret the information in microbial ""fecal prints""– until now. Weizmann's Dr. Itay Halevy and McGill's Dr. Boswell Wing have cracked the case.

    Climate Change: A Planetary Perspective, Prof. Oded Aharonson

    At this TEDx event at the Weizmann Institute, planetary scientist Prof. Oded Aharonson takes on climate change by asking two questions: to what extent is climate change about what we do the earth, and to what extent is it about what the itself earth does (by moving, etc.)? After all, Earth's rotation around the sun is not static. Neither, of course, are we unpredictable humans.

    First Oceans May Have Been Acidic

    Looking back at the very earliest oceans, Dr. Itay Halevy found that they started off acidic and gradually became alkaline. His work sheds light on how levels of ocean acidity in the past were controlled by carbon dioxide in the atmosphere, an important process for understanding the effects of climate change, as today the oceans are again becoming acidic.

    Off Track: How Storms Will Veer in a Warmer World

    Under global climate change, the Earth’s climatic zones will shift toward the poles. This is not just a prediction; it is a trend that has already been observed in the past decades. The dry, semi-arid regions are expanding into higher latitudes, and temperate, rainy regions are migrating poleward. In a paper that that was recently published in Nature Geoscience, Weizmann Institute of Science researchers provide new insight into this phenomenon by discovering that mid-latitude storms are steered further toward the poles in a warmer climate. Their analysis, which also revealed the physical mechanisms controlling this phenomenon, involved a unique approach that traced the progression of low-pressure weather systems both from the outside – in their movement around the globe – and the inside, analyzing the storms’ dynamics.

    Deadly Floods Will be the ‘New Normal’

    In warming climates, mid-latitude storms will travel further toward the poles before they reach their maximum intensity - and this, scientists say, will be the ‘new normal’. The study suggests that impacts on weather and climate will be strongest in regions close to the northeastern ocean boundaries, such as the UK and the US west coast.
