Climate change: what would 4°C of global warming feel like? – The Conversation UK

Another year, another climate record broken. Globally, 2020 tied with 2016 as the warmest year ever recorded. This was all the more remarkable given that cool conditions in the Pacific Ocean – known as La Niña – began to emerge…

Extreme fire weather

(University of California – Santa Barbara) When the Thomas Fire raged through Ventura and Santa Barbara counties in December 2017, Danielle Touma, at the time an earth science researcher at Stanford, was stunned by its severity. Burning for more than a month and scorching 440 square miles, the fire was then considered the worst in California’s history.

Need to reduce work-related stress? It’s a walk in the park

Research examined the relationship between ‘sense of coherence’ (a quality indicative of stress-coping ability) and frequency of walking in forests or greenspaces. The aim was to find easy coping devices for workplace stress. Forest/greenspace walking at least once a week was found to correlate with those with a stronger sense of coherence. The findings suggest the benefits of walking in urban greenspaces or in forests to help with stress management.

Power, water and climate

As the planet continues to warm, the twin challenges of diminishing water supply and growing energy demand will intensify. But water and energy are inextricably linked. For instance, nearly a fifth of California’s energy goes toward water-related activities, while more than a tenth of the state’s electricity comes from hydropower. As society tries to adapt to one challenge, it needs to ensure it doesn’t worsen the other.

How global warming is changing city temperatures – Quartz

Scientists have long known that cities tend to be warmer than their surroundings—by 10° Fahrenheit (5.5° Celsius) on average in the US. The urban heat island effect, as it’s known, is produced by the abundance of heat-trapping asphalt and concrete, smog,…

First global study shows uneven urbanization among large cities in the last two decades

In the first-ever study on the characteristics of urbanization in large cities around the world, researchers at the University of Hong Kong analyzed cities’ urban built-up areas (BUAs) expansion, population growth and greening BUA changes, and revealed a hugely uneven pace of urbanization in those cities in the last two decades. They warn against major challenges posed to sustainable development if the urban problems are not dealt with in a timely manner.
