Tonga volcanic eruption not likely to cause global climate change, says New Zealand volcanologist******

The Tonga volcanic eruption is not likely to cause global climate change, while the volcanic ash and acid rain may damage crops and water supply, a leading New Zealand volcanologist said Monday.。

Professor Shane Cronin of the University of Auckland, who visited the Hunga-Tonga Hunga-Ha'apai volcano in November 2015, has explained the uniqueness of the volcanic event and its impacts.。

According to the professor, the most significant impact so far has been the tsunami generated at the beginning of the eruption.。

"Thankfully, the tsunami in Tonga was not so big," said the professor.。

All the homes on one of Tonga's small outer islands were destroyed in the massive volcanic eruption and tsunami, with three people confirmed dead so far, the government said on Tuesday in its first update since the disaster hit.。

"But mostly the damage is not so far from the coast and especially confined to a few very low-lying areas. Thankfully, most people were able to get away from those waves," he said.。

The other impacts locally in Tonga are from the ashfall. "Thankfully again, the ashes mostly fell into the ocean. On the Tongatapu island, there were reports of two centimeters of ash. This ash will impact water supply and some broad-leaf crops like corn, banana and squash, but unless there are more eruptions, this effect should allow a quick plant recovery."

Professor Cronin noted that most of the volcanic plumes from Saturday's eruption were in the troposphere or lower part of the atmosphere, below 25 km. Along with this short eruption means that there is not much aerosol to reflect sunlight and cause global cooling.。

"Most of the ash plume and gas plume that went into the air contains gases like sulpha dioxide. The rain will wash them down. There was not too large a volume of particles and aerosols high enough in the atmosphere to cause global cooling," he said.。

But the impact from acid rains for the affected areas such as Tonga and parts of eastern Fiji could be real. Should there be many more eruptions to come, and the acid rain continues, it could be more damaging for crops and water supply.。

The longer-term effects of the volcanic eruption on marine life could be significant, he said.。

On the downside, the local fishing and marine life will experience many changes as part of the volcano is destroyed. But there is some bright side along with the volcanic ashes in the longer term.。

"Because when ash falls into the ocean, it brings with it nutrients. For example, It can bring iron, which is usually quite low in the ocean. It can suddenly create a bloom of plankton, which then go through the food chain, creating a population boom later on the fish and other lives too," said Professor Cronin.。

According to the professor, a series of more minor eruptions happened in the submarine volcano in 1998, 2009, 2014, 2015 and perhaps even earlier than that. Saturday's eruption was so severe because a lot of the magma in the volcano had been building up for at least 10 years, or maybe longer.。

"The magma accumulates to a large size inside the volcaNo. The pressure of the magma, built up to a point that the top of the volcano can no longer hold it. At this point cracks start to happen, until suddenly the magma is released. The magma is full of gas and it expands extremely rapidly," said Professor Cronin.。

The central part of the Hunga volcano is about 150 meters to 300 meters below sea level. The amount of water that went into the crater was just big enough to fuel the big explosion that has sent waves of air pressure traveling around the world.。

"Also, tsunami waves were generated by the initial expansion as well as by changes in the surface on the top of the volcano," Professor Cronin said.。

"The maximum power of this eruption was very strong, equivalent to the Mount Pinatubo eruption in 1991 in the Philippines. However, the Saturday eruption was a very short one. It lasted less than 10 minutes for its main active phase. In contrast, the Pinatubo lasted for many hours," he said.。

The short period means that the overall amount of materials released from this eruption was relatively small. "We think around 0.5 cubic kilometers of materials was ejected into the air," Cronin said.。

The professor's best guess is the lower level of the VEI 5 range. "Which is roughly one per 10 years around the world for such a size," he said. "It may be more sort of normal mid-scale large eruption volume."

However, it is very difficult to predict what might happen next.。

"I would suggest that the eruption may be less violent from now on because the beginning of this eruption was all these pent-up magmas with a lot of trapped gas in it," Professor Cronin said.。

He also warned of future tsunami events. "This volcano is shallow and still have seawater on top. So any further eruptions or any collapse from the volcano can cause a tsunami in the local region. Probably there will be less wide-spread tsunami."

China maps path to carbon peak, neutrality under new development philosophy******

BEIJING, Oct. 24 (Xinhua) -- Chinese authorities on Sunday unveiled a guiding document on the country's work to achieve carbon peaking and carbon neutrality goals under the new development philosophy, laying out key specific targets and measures for upcoming decades.

By 2030, China's carbon dioxide emissions will peak, stabilize and then decline, and by 2060, China will be carbon neutral and have fully established a green, low-carbon and circular economy, it said, reiterating the country's previous pledge.

Toward this end, China aims to gradually increase the share of non-fossil energy consumption to around 20 percent by 2025, around 25 percent by 2030, and over 80 percent by 2060, according to the document jointly released by the Communist Party of China Central Committee and the State Council.

The country's carbon dioxide emissions per unit of GDP will be lowered by 18 percent from the 2020 level by 2025 and will have dropped by more than 65 percent compared with the 2005 level by 2030, said the document titled "Working Guidance For Carbon Dioxide Peaking And Carbon Neutrality In Full And Faithful Implementation Of The New Development Philosophy."

酸奶还可以这样吃,我这也是在挪威食堂学来的,快试试吧,更香更醇******

原标题:酸奶还可以这样吃,我这也是在挪威食堂学来的,快试试吧,更香更醇

华夫饼在挪威非常的流行,在一些小卖部经常会看到现做现卖的。

还有许多单位食堂周五也会供应。

挪威人吃华夫通常是配酸奶油、挪威的棕色奶酪、草莓酱或树莓果酱,也有的人爱用蓝莓酱。还可以配冰淇淋和草莓等浆果,这就是升级版的,聚会时会这样的。

咱今天就用了新鲜的草莓,春天正是草莓季。

酸奶加到华夫饼中更加香浓醇厚,我这也是在挪威食堂学来的,快试试吧

今天我做的华夫饼配方与你通常的不完全一样,这还是我在食堂打工时跟大厨学来了,那天新来了一位厨师,他将酸奶油加到华夫饼的面糊里,我原本以为会酸,可没想到口感特别好。

后来大厨又跟我说也可用酸奶,比酸奶油的口感略为清爽些。打那以后,我最常做的就是用用酸奶代替部分牛奶,使得华夫饼的口感更加多元化。

酸奶华夫饼

材料:面粉300克、鸡蛋2个、牛奶300毫升、酸奶120毫升、黄油60克、糖60克、泡打粉1茶匙、豆蔻少许

003

制作:

首先制作华夫饼面糊,方法有两种。

第一种方法:你可以先将鸡蛋加白糖,用电动打蛋器打到发白;再加入酸奶和牛奶,轻打几下打匀;然后加入融化的黄油,轻打几下打匀;最后筛入面粉、泡打粉、豆蔻粉,轻打几下打匀,成为细腻的面糊。

第二种方法:你也可以将全部材料倒入料理桶中,用电动打蛋器的低档,轻打几下打匀成细腻,无颗粒的面糊就可,请不要过分搅拌。

拌好的面糊最好静置半小时以上,也可提前一天做好。

华夫机烧到温热,上下烤盘都刷一层黄油,一般来说第一张饼刷油就可以了,讲究的通常第一张不食用,用第一张饼粘去机器的异味。

舀一勺子华夫饼面糊到华夫机烤盘中,迅速盖上盖。

看到冒出来的蒸汽越来越少基本上就可以了,颜色依据你的喜爱调整。

依次做完全部的面糊,做好的先放在架子上,不要急于叠放在一起,否则会变软。

挪威人吃华夫饼的时候,最传统的是配酸奶油、挪威棕色山羊奶酪、草莓果酱、树莓果酱。

当然了你也可配其它的果酱如蓝莓酱,或者加些新鲜的草莓。

细微小语:

两种调配面糊的方法都可以,不会影响最终的口感,只要注意不要过分搅拌就好,如果面疙瘩过多,又没有电动打蛋器的话,可以过一下筛。
