The next fish to die soon?

the climate is changing That is hardly controversial. Which is why, rather. What is this climate change with us, here in Switzerland, here in Zurich does, to show the newly published climate scenarios CH2018. They were created under the leadership of Meteo Schweiz and the ETH Zurich , and from the Awel (office for waste, water, energy and air) specifically for the Canton of Zurich were evaluated.

The bad news: We are during the day more often, like the dead fly around, because it is too hot for activities. The good news: The climate protection effect. It slows down the negative Trend and stabilized him, from 2035 in the case of a number of factors. This, however, only if the measures are rapidly and globally taken and as a result, the greenhouse gas emissions significantly decrease.

The maximum temperatures to take in accordance with the new climate scenarios significantly more than the average temperatures. The accentuated still in the city and the Agglomeration. As Kloten calculated without climate protection for the year 2035 at the site Zurich-up to 22 high-temperature days, the Median of the simulations is around 14. Between 1981 and 2010, an average of 8, the last year 16.

In Wädenswil, although it is a bit cooler, but the number of hot days is still significantly higher than it is today. On hot days the temperature is over 30 degrees Celsius. Also nights where the temperature falls below 20 degrees, the Tropics will increase.

Longer

by the middle of this century, hay fever is likely to, according to Awel conditions, such as in the summer of 2018 and 2015 to be the norm. Heat waves will be more intense and longer, which can be especially for the health of the elderly and infants-threatening. The ozone levels, which increase during such periods of hot weather to come. The rising temperatures will affect but also the well-being of healthy and strong people. For example, the plants begin to bloom earlier, and the Vegetation period lasts longer, so that the hay fever season is extended.

conversely, the frost slim days: in 1995, the temperatures in Kloten decreased to 92 days per year below zero degrees. By 2035, this would be at about 74 days, the case, if climate protection. In Wädenswil, the value in said period of time decreases from 74 to 59 days of frost. Even more worrying is the amount of precipitation, but are Dry in summer and in 2015 and 2018, are more frequent, and the dry periods will last longer. 2035 will decrease according to the forecasts in North-East Switzerland, the average amount of precipitation in the summer compared to the norm for the period 1981 to 2010 by up to 18 percent.

What are the effects of the had to the farmers last year, the painful experience you had. loss of Earnings, for example, in the case of Grass and Corn, and some had to slaughter their cows early because they were able to bring in little hay Not to mention the mullet die, and the most elaborate displacement of fish.

New diseases threaten

a Particularly bitter, the more frequent and longer-lasting will be felt dry periods in those that are already under great pressure: bogs and other wetlands. So many rare animals and plants will lose more and more their way of life.

conversely, some plant and animal benefit types, which can be a plague. So, for example, the for cows poisonous narrow-leaved Groundsel. Also, the Asian tiger mosquito could be in the Canton of Zurich and new diseases. If it is raining, then pouring, because warm air can hold more moisture. The risk of Flooding is increasing, according to Abel. It reminds that in 2005, lacked only a little, and the Sihl would have flooded the inner city of Zurich and the main train station. Since then there have been and will be taken in the whole Canton of expensive high-water measures. According to these scenarios, you will be urgently needed.

Dry summers, more rainfall in Winter because of the higher temperatures this fall, but more as rain than as snow. So, in 1995, fell in the space of Kloten in 13 days, inches of snow or more. This will not change until 2035, although approximately 10 percent more precipitation can be expected than in the standard period.

According to the newly published issue of the magazine "Zurich's environmental practice" will halve the blanket of Snow already by mid-century, below 1000 meters.
