The largest amount of ice accumulated on the glacier
belongs to the Alps sequence to a record low
Research by the Swiss Science Institute said that although 2020 is not a year with the peak tape, the glaciers in the Switzerland's Alps are constantly narrowing, losing 2% of the ice volume in the year.now.Dr. Matthias Huss belongs to the glacier tracking network (Glamos), the identification of the lost ice is very "worrying" although a bit lower than the last 3 years in the context of increasing earth temperature.High.He emphasized that the amount of ice lost 2% in just one year was really a lot.
Over the past 60 years, the amount of water that has been lost on glaciers in Switzerland is enough to fill the Constance lake located on the border of 3 countries Switzerland, Germany and Austria, stretching 63 km.The study also found that the most worrying thing this year was that the amount of ice accumulated on the Aletsch glacier dropped to a record low.
The satellite photographer provided by NASA, clearly visible landslides on the mountainside due to melting.
Dr. Huss said that since the measurement was carried out in this area more than 100 years ago, the amount of ice accumulated on the Aletsch glacier this year was at the "lowest" level.He emphasized that although this place is still cold, the amount of ice still exists at this height is still too little, and this is definitely a bad sign for the Aletsch glacier.
The Aletsch glacier is located on an area of 86 km2 and an estimated storage of about 11 billion tons of ice, which has been narrowed about 1 km long since the beginning of the 21st century.This glacier is among more than 4,000 glaciers scattered on the Alps, providing water for millions of people and creating some of the most spectacular landscapes in Europe.
In a study conducted by ETH Technical University in Zurich, Switzerland and published last year, about 95% of the above glaciers will disappear in 2100 if countries around the world do not control the amount.Greenhouse emissions.According to this forecast, even if the world achieved the goal set in the Paris agreement on climate change signed in 2015, it kept the Earth's temperature at less than 2 degrees Celsius compared to the pre -industrial period,There are still 2/3 of the glaciers of the Alps in the risk of disappearing.
The glacier disappears, the tsunami appears
In Alaska and other high and cold places in the world, scientists have recorded the situation of the mountains collapsing when the permanent ice layer holds them together melting.The mountains falling into the sea can create a tsunami.Scientists are warning that densely populated areas and tourist destinations in these areas are in danger of being affected.
An area of interest is the slope of the Barry Arm narrow in Alaska overlooking the famous tourist route.
The landslide in Barry Arm Bay began to appear from the beginning of the last century, accelerating a decade ago and was discovered this year through NASA satellite photos.If the landslide occurs, super tsunami attacks can enter anytime in the area and hundreds of meters high, pouring on nearby mountains, engulfing famous tourist destinations and swallowing townsWhittier.Earlier this year, 14 geological houses warned that a "can occur" within 1 to 20 years.

In 2015, a similar landslide, on a slope, has been silently taking place for decades, creating a tsunami to tear the forests at a height of 193 meters on the slopes of Alaska's Taan Ford mountain..
"When the climate changes," the Geologist Bretwood Higman, who studied in the Taan Ford and Barry Arm areas, said, "the landscape takes time to adjust.Quickly, it can cause the surrounding mountains surrounded by landslides. "
After considering satellite photos in the past 30 years, geologist Erin Bessette-Kirton has discovered that the landslide in the mountains of Alaska's St Elias and Glacier Bay occurred corresponding to the warmest years.
In the past century, 10 out of the 14 highest tsunami has been recorded in mountainous areas with ice.In 1958, an landslide in Alaska's Lituya Baya created a 524 meter high wave - the highest ever recorded.In the earthquake in 1964 in Alaska, most of the deaths were due to underwater landslides leading to tsunamis.
To deal with this danger, experts hope to predict when a slope is more likely to erode by installing sensors on the most dangerous slopes to measure acceleration.
Technological solutions can be solved
Crisis of ice crisis
The detection and use of fossil fuels have contributed to climate change but they also allow humanity to be aware of human impact on the planet and realize the need to develop techniques to solve.Decide the global warming.
Carbon shooting

The average increasing temperature of the Earth is mainly blamed by scientists because people emit greenhouse gases that have kept radiation in the atmosphere instead of escaping from space.
Among the most dangerous greenhouse gases, Carbon Dioxide (CO2), their concentration has increased by nearly 50% since the industrial revolution began.
Innovations are being used to reduce CO2 emissions including carbon seizure, use and storage technology - with Net Zero Teesside (NZT) project is an interesting example.
The NZT project aims to seize CO2 in industrial processes and power plants, transporting this emissions by pipes to offshore storage points a few kilometers from the North.This gas is then isolated in deep safe areas under the sea, carbon then will no longer contribute to the greenhouse effect and it can even be synthesized into new fuel for the transport system.In the future.The purpose is to reduce the amount of carbon emissions in some industries using carbon to 0 in early 2030.
For cows to eat seaweed

Another significant greenhouse gas is methane, this emissions are reaching a record level due to cattle raising.
According to a recent study by British scientists, agriculture accounted for about two-thirds of the total amount of Mekong emissions from 2000 to 2017, fossil fuel contributed greatly on the other 3/3.
Seaweed cows will release less methane in the process of digesting food
This methane is mainly from belching cattle due to the way the fermentation of fermented foods in their stomachs.Scientists have discovered that a red seaweed growing in the tropics can reduce the amount of methane emitted in cows when it is added to animal feed.
However, with nearly 1.5 billion cattle heads worldwide, there are currently no all kinds of seaweed to prevent belching although some scientists can recreate an important ingredient in the type of seaweed.This sea.
Remotely work

Cover-19 pandemic has shown that many office work can be worked remotely, which means reducing emissions from vehicles and office buildings.Driving to work is the largest source of carbon emissions in developed countries.
Remote working support technology has been quickly applied when businesses try to adapt to the impact of Covid-19 epidemic during the time when governments apply the provisions of the infection.
However, working remotely may be an effective method to reduce emissions in the summer.Because it indicates that when buildings need to be warmed in the winter, having many people in a building will be much more effective than working remotely.
Effective use of household energy

The most efficient technology solution for climate change is to reduce overall energy consumption and the best thing is to make houses more energy -saving.
The technology to achieve this has, with many of the latest products on the market capable of saving hundreds of pounds of family invoices every year.
The European Union has established a labeling program for devices for evaluating energy saving levels, notifying consumers about the cost they pay to run refrigerators and washing machines, as well as products.Other products from light bulbs to television.
Across the EU, buildings consume 40% of the total energy and take responsibility for 35% of CO2 emissions, while the energy consumption per household has decreased over the past 50 years due to effective measures..
