What is Climate Change ? Defination, Causes and Effects
What is Climate Change ?
Climate change is the change in the average weather conditions on Earth, a direct result of the increasing concentrations of greenhouse gases in our atmosphere. Climate warming is one of the greatest global risks for people and society. In simple terms, in Flanders it will provide ‘more heat waves, drier summers, wetter winters and a rising sea level’.
Climate change has changed dramatically in the last 4.6 billion years of global history and has long-term effects on climate systems and ecosystems. Climate and geomorphological effects are well known and climate changes during glacial and interglacial periods of the 4th quarter (Quaternary) are nearly 2 million years old. This happens under natural conditions.
However, since the 19th century the impact of human activities on climate has grown tremendously. Utilization of fossil fuels, industrial production, increase and use of uncultivated land, forest destruction, etc. Greenhouse gas emissions have increased as a result of many human activities. As a result of automated power, short-term unemployment shrinkage caused accumulation. The impact of greenhouse gas emissions is particularly significant on the global energy balance. It causes nervous stress of concentration and changes in weathering properties and causes the temperature to rise.
Climate change is statistical changes observed in average weather conditions and statistical differences between the length of the entire area and the time scales. The change depends on internal and external factors. External factors include transmissions and related functions, and internal objects with anthropogenic functions. In addition to the definition of climate change, a UN Conference on Climate Change described climate change as a result of direct or indirect anthropogenic effects on climate change.
We consider climate change within the end of global warming. Global warming is causing changes in hydraulic systems, melting of ice and glaciers, increasing sea levels, droughts and hot air waves in frequency / intensity patterns, very early observations and floods, and negative effects of ecosystems and socio-economic sectors.
What Causes Climate change
Climate change due to Human Activities
The greenhouse gases in the atmosphere make the effect of the greenhouse stronger. Activities such as industrial processes, agriculture, deforestation and the use of fossil energy sources beyond the capacity of greenhouse gases and increasing the temperature at low and medium temperatures are a major reason for global warming. In addition, the concentration of aerosols accumulated in storage as a result of the use of fossil energy sources alters cloud costs and reflective properties. It creates a radiative wall forcing the cooling behavior. In addition, volcanic ash particles emit a certain amount of radiation from the sun, causing the water column and ground to cool.
Some Climate Change
Since 1980, global warming, which is more predictable, has increased by 0.7 degrees. The best year with a widget of 0.58 degrees in 1998. The result obtained in the 2005 data was effective nationwide, 0.485 degrees and in the northern hemisphere 0.648 degrees. Every 10 years, the minimum daily temperature by 0.2 degrees. The world’s fifth-degree global temperature range has a temperature of 100 degrees Celsius.
This shows that the temperature has reached twice the temperature of 100 times in the last 50 years. In the last 40 years, the temperature has been higher in the lower layers and the center of gravity compared to 1300 years ago. This affects the land and the seas as well as on the small mass. This increases water retention capacity of the hot air. Research from the 1960s to the present day shows that the average temperature of the oceans increased to a depth of less than 3000 meters and the surface area received 80 percent of the thermal energy. This heat causes water expansion and causes sea levels to rise.
In addition, a noticeable reduction in the upper glaciers and average snow cover was included in the 3rd TAR report. The report explains that the loss of Greenland and Antarctic icebergs contributed to an increase in sea level, and the floating language, ice strains and mass loss were assessed. Reduction and voltage reduction of the snow cover and the top / sea glaciers of the polar and mid latitude continue at speed. As a result of sea level rise and wall measurements, it has been shown that the rise has increased by 20-0.12 m in 0.22 years. While the coverage rates of the 1961-2003 season were 1.3-2.3 mm / year, the cover periods of the 1993-2003 season were determined as 2.4-3.8 mm / year.
The most important way to reduce past climate change and their negative impact on the economy, human ecosystem and human health is to reduce human emissions from excess. Procedures and measures to reduce or control greenhouse gas emissions are being implemented to reduce greenhouse gas emissions and / or with scientific and technological / technological and technological approaches and possible macro policy tools to do in the near future.
Some Examples of Climate Changes
All forecasts and elimination scenarios based on the Intergovernmental Panel on Climate Change (IPCC) Fourth Report will indicate that the accumulation of carbon dioxide in the atmosphere, sea temperatures and sea levels will rise during the 21st century; ground and ice / glaciers are expected to lose large mass in size and area.
Temperature: Global temperatures of 100 years will increase by 2 degrees if CO2 concentration doubles. According to most SRES divorce statistics, 10 warming will occur every 0.2 years.
Precipitation: It has been predicted that precipitation levels will increase in Antarctica, tropical Africa, central and latitude north in winter and in south and east Asia in summer. This is in the direction of area increase or area reduction at low latitudes. Precipitation in the precipitation will cause an increase in night water in areas of the ground, which in turn causes land reclamation and runoff. The extent of dry and drought-prone areas is expected to cause driving and long periods of time in precipitation.
Ice : The distribution of snow cover in the north-north is expected to decrease. Transformation losses will continue to occur as a result of thermal expansion of formulas such as sea ice, ice rock, ice cap, ice. However, it is expected that the Greenland iceberg will lose place due to an increase in currents, and the Antarctic ice enemy is expected to be in place due to an increase in rainfall. West Ice ice is below sea level and is likely to lose its stability.
Sea level: The first prediction by TAR is that the median sea level will rise between 1990-2100 meters between 0.09-0.88.
What is the effect of climate change ?
● The annual average temperature in Flanders has increased sharply (+2.5 ° C).
● More tropical days (≥ 30 ° C) are recorded and heat waves are more frequent.
● The annual average amount of rainfall is increasing.
● Winters are wetter and summer thunderstorms are more frequent and intense.
● The sea level is rising and the sea water is getting warmer.
What are the effects of climate change ?
In wetter winters :
- Our winters and our soils are getting wetter. This will encourage higher peak discharges and lead to more and larger floods from watercourses.
- The chance of river flooding can increase by a factor of 5-10.
- The flood levels can rise by an average of 20 cm.
- Flooding and flooding damage buildings and infrastructure.
In drier summers
- The drier summers will lead to drought and water scarcity, which can cause:
- drinking water shortage;
- yield losses in the agricultural sector;
- too little draft for shipping;
- poorer water quality (including fish mortality).
On our health
- Climate change will also impact human health by:
- heat waves;
- summer smog;
- hay fever;
- infectious diseases;
- contaminated food and water.
