Katla volcano is hidden under the ice cover of the Mýrdalsjökull glacier in Iceland and erupted every 40 to 80 years in history. With such a recent eruption, the previous Catla eruption that occurred 100 years ago in 1918 should have erupted faster.

A new study by Iceland and UK geologists shows that Katla emits a lot of carbon dioxide every day - at least 20 kilotons of carbon dioxide. Evgenia Ilyinskaya, volcanologist at the University of Leeds, to the Iceland National Broadcasting Corporation as follows:

Evgenia told RÚV as follows. "These huge amounts of carbon dioxide emissions confirm the importance of volcanic activity." Magma must also be made to release this amount of natural gas.

"Other volcanoes are also well known, the amount of carbon dioxide emitted by volcanic eruptions will increase in a few weeks or years, which means that we need to pay close attention to Katra Obvious signs. "

The biggest glacier flood in Iceland's history occurred at the beginning of the Catalonian volcanic eruption of 1918. The story of this flood is scary. It is a dense mixture of molten water, volcanic ash, and ice, but as it progresses very quickly it can only ride a horse and escape the road. It covers hundreds of square kilometers; today's flood will destroy the Icelandic ring road and many important facilities in the southern part of the country.

The core of ice and sediment reveals a wonderful history of global climate. The core is gathered by driving long hollow tubes of up to 2 miles into glacial ice and seabed deposits. Ice score provides yearly and seasonal climate records over hundreds of thousands of years and complements millions of years of climate records in marine sediment cores. The temperature of the earth fluctuates frequently and rapidly in a short period of time. From various records, countless large and rapid climate changes over the past 100,000 years are revealed. One of the most interesting recent discoveries is the amazing speed of these changes. For very short periods (according to geological standards) of only a few decades, or even years later, global temperature fluctuations will be more than 15 ° F (8 ° C).

Climate can be explained on various scales. The global climate is the average temperature of the Earth's surface and the atmosphere it is in contact with and is measured by analyzing thousands of temperature records collected from locations around the world (land and sea). The latest climate change projections are related to the global climate, but the climate can also be described on other scales based on the record of weather variables collected from the relevant regional observatories. Regional climate is as follows.

The term "global climate change" usually refers to changes in the Earth's climate caused by various human activities. Global climate change is sometimes called "global warming" because the global average temperature is expected to rise steadily. Regardless of the terms used, the different power generation methods affect the earth's climate in such a way as to cause specific environmental problems. There is an increasing scientific evidence that fossil fuels such as coal, petroleum and natural gas burning are changing the climate of the earth. The burning fossil fuel releases millions of years of carbon that was previously trapped in coal, oil and natural gas. Carbon in these fossil fuels is converted into carbon dioxide (CO2), the main gas that causes "greenhouse effect" in the combustion process.
