1 . Cloud “engineering” could be more effective for climate cooling than previously thought, because of the increased cloud cover produced, new research shows.
In a study published in Nature Geoscience, researchers at the University of Birmingham found that marine cloud brightening (MCB), also known as marine cloud engineering, works primarily by increasing the amount of cloud cover, accounting for 60% — 90% of the cooling effect.
The practice of MCB has attracted much attention in recent years as a way of offsetting the global warming effects caused by humans and buying some time while the global economy decarbonizes (脱碳). It works by spraying tiny particles, or aerosols (气溶胶), into the atmosphere where they mix with clouds and with the primary aim of increasing the amount of sunlight that clouds can reflect.
However, the ways in which MCB creates a cooling effect, and the ways in which clouds will respond to aerosols, are still poorly understood. To investigate the phenomenon, the researchers created a “natural experiment”, using aerosol injection from the effusive eruption of Kilauea volcano in Hawaii to study the interactions between these natural aerosols, clouds, and climate.
Using machine learning and historic satellite and meteorological (气象学的) data, the team created a predictor to show how the cloud would behave during periods when the volcano was inactive. This predictor enabled them to identify clearly the impacts on the clouds that had been directly caused by the volcanic aerosols.
They were able to show that the cloud cover relatively increased by up to 50% during the periods of volcanic activity, producing a cooling effect of up to — 10 W/m² regionally.
Lead author, Dr Ying Chen, of the University of Birmingham, said, “Our findings show that marine cloud brightening could be more effective as a climate intervention than climate models have suggested previously. Of course, while it could be useful, MCB does not address the underlying causes of global warming from greenhouse gases produced by human activities. It should therefore be regarded as a ‘painkiller’, rather than a solution.”

2 . The months of July and August are often known as the “dog days of summer”, bringing in longer, hotter and sunnier days for you to throw the perfect dog birthday party.
Choosing the right spotIf you’re lucky enough to have a garden big enough, that couldn’t be better.
Dogs love to socialise and play together, so why not bring a few activities into the mix. From frozen lick mats, tug of war to even a mini swimming pool, there are plenty of options to keep the guests of honour entertained.
Photos of your puppy party will give you memories to look back on forever, and who doesn’t love showing their pup off online? Add some props (道具) and a special backdrop to make your pictures even more double-tap worthy.
Don’t forget the humansWhile the puppies are undoubtedly the real stars of the party, you can’t forget about your fellow human guests. Consider dog-themed treats, drinks and music. And finally, don’t send your guests home empty-pawed.

9 . When Mark Twain visited Florence (佛罗伦萨) in 1867, he dutifully visited the city’s museums, churches, and tombs. But as he stood by the Arno, he began to sense the Italians’ insistence that it was a river, not a stream. “They all call it a river, and they honestly think it is a river, do these dark and bloody Florentines,” he complained, “I might enter Florence under happier circumstances a month hence and find it all beautiful, all attractive. But I do not care to think of it now, at all.”
It’s normal to feel uncomfortable outside your home culture. Feelings of discomfort, dislocation, and overload among travelers are referred to by many as “culture shock.” But Susan Goldstein, a professor at the University of Redlands says, “ Though the term has existed for many years, ‘Culture shock’ implies a dramatic, unexpected, negative event. Though many travelers will experience such challenges, a real sense of ‘shock’ is untypical. So untypical that many researchers no longer use the term.”
It was the vivid description of culture shock by Canadian researcher Oberg, written in 1960 in response to his own multicultural experiences, that won over audiences. The researcher spoke of the adjustment process as “an occupational disease of people who have suddenly been transplanted abroad” — a “disease” that progressed from a honeymoon phase, through rejecting the new environment, to finally adjusting fully to it. By the 1970s many researchers adopted the idea that, like physical illnesses, culture shock progressed through a remarkably consistent and universal set of stages.
Modern research, however, suggests that the experiences of adaptation are individual, not universal. “People will have their ups and downs, but for the most part, they will become increasingly comfortable and competent over time,” Goldstein says. And while many connect the causes of culture shock to the host culture itself, an individual’s internal expectations and differences are just as important.
As for Mark Twain, the moody author was able to ride out his feelings of upset and dislocation while traveling. He eventually finished out his European tour - and in his bestselling travel memoir The Innocents Abroad, famously remarked that travel is “fatal to prejudice and narrow-mindedness.” With the right attitude - and the willingness to seek help if you need it - it’s more than likely that you, too, can adapt and grow in new settings, building new memories-and toughness - with each new stamp in your passport.

10 . Powerful Benefits of Journaling
When looking for a way to better manage stress and feel your best, consider adding journaling to.
Practice journaling as therapy (治疗)
By making journaling a regular practice, you create a space for self-reflection that can lead to personal growth and psychological treatment.
Release and process feelings
Help recognize sources of stress
Think of it as a safe space to express how you feel, leading to a significant decrease in stress levels. Sometimes the first step in building the life you want starts with simple awareness. Journaling gives you a chance to recognize what stresses you out in the first place.
Promote mindfulness
Journaling brings your focus to the present. Just like in mindful meditation (冥想), journaling gives you an outlet to observe thoughts and emotions without judgment. Think of this as an act of self-love, to accept yourself in the present moment just as you are.
A.This practice goes beyond just recording daily events |
B.Even just five minutes can help gain some comprehension |
C.Sometimes people find it challenging to express their emotions. |
D.This mindfulness aspect provides a crucial tool in reducing stress. |
E.Once you notice bad situations, you can remove that source of stress. |
F.This can enhance decision-making skills and promote an approach to life’s difficulties. |
