Climate Change: Why it is, Why it is matter and how we can help

 What is Climate?

Climate is refers to long-term patterns of weather in a specific region over decades and centuries. Unlike daily weather, which can vary widely, climate is generally stable and predictable over long period. Key factors influencing climate include temperature, humidity, atmospheric pressure, rainfall and some other specific conditions of atmosphere.
Climate has some types which are 
  • Temperate climate: Characterized by moderate weather.
  • Polar climate: Cold-year round, typically found in Arctic and Antarctica.
  • Tropical climate: Warm and humid, common near to equator.
  • Continental climate: Marked by extreme temperatures, often in inland areas.

What is Climate Change?

Climate change refers to significant alteration in atmospheric conditions over extended periods. As climate change increasingly impact every part of our world. Primary cause of recent climate change is human activities, though natural processes also contribute.

Climate change due to human activities:

        Common causes of human-induced climate change include
  • Burning fossil fuels for domestic and industrial use
  • Deforestation (clearance of large area of forest)
  • Utilization of chlorofluorocarbons (CFCs) 
  • Use of insecticides and pesticides in agriculture
  • Industrial toxic wastes
  • Uses of cars, buses, air craft and ship for Transportation
These are some common causes of climate change which are occur by humans.

Climate Change caused by natural processes:

  • Change in sun activity
  • Levels of carbon dioxides
  • Variation in earth's orbit
  • Emissions from volcanoes
 Moreover decaying of organic matter produce ammonia which is natural cause of climate change.

Impact:

     It has several negative impacts on our ecosystem including
  • Rising sea levels 
  • Global warming 
  • Rise in greenhouse effect
  • Ice melting in polar region
  • Extreme weather
  • Increased global temperatures
  • Threats to wild life
  • Reduction of ozone layer
These are some major impact of climate change on world .

What are Greenhouse effect and Global Warming?

Greenhouse effect:

When sunlight reach earth's surface part of it is absorbed and part is reflected in the form of heat. In atmosphere certain gases known as greenhouse gases (which prevent heat to escape out from them) including carbon dioxide(CO₂),  methane(CH₄), nitrous oxide(N₂O) and water vapors(H₂O) absorb this heat and heat up atmospheric temperature. This heat-trapping process is known 
as greenhouse effect. 
Without this process the atmospheric temperature would be too cold for life. On the other hand increase of greenhouse gases lead to change in temperature by absorbing more heat that causes extreme weather and climate change. 

Global Warming:    

Some human activities causes increase the greenhouse effect, which is gradually raising temperatures, which is known as global warming.  Major cause of global warming are burning of fossil fuels which produces greenhouse gases  and Oxides of nitrogen (NOx) which trap heat comes from sun.

Negative impact:

  • Melting of ice capes and glaciers lead to rising sea levels, increase bringing risks 
  • Change the path of air and ocean currents 
  • Loss of biodiversity
  • Crop failures and food insecurity
Global warming is very dangerous for future. We should try to minimize Global warming to save our future.

Solution of Climate Change:

    We can minimize climate change by some adapting efforts and rules.
  • Plants are natural source of absorption of carbon dioxide(CO₂). Reforestation (growing of new forest) is very important in this regard.
  • Use alternate sources of energy such as wind energy, hydrostatic energy and some other kind of sources in the replacement of fossil fuels.
  • Build power plants for capturing of CO₂ from atmosphere.
  • Promote speeches and websites about bad impact of climate change for awareness of people.
  • Discuss about climate change in ecological conferences and give solutions.
  • Government should strict for uses of chlorofluorocarbons (CFCs) and toxic substances.
  • Promote 3R cycle (Reduce, Reuse, Recycle) to minimize waste release into the atmosphere.
  • Protect aquatic ecosystem because water can absorb large amount of CO₂ from air.
  • Industrial waste should be release in atmosphere after filtration.
These are common solutions for minimizing climate change on our earth to save our future.

What Are Mycorrhizae? Types and Their Role in Plant Growth

Image
What is mycorrhizae?       It is the relationship between fungi and higher vascular plant. The fungi  attach to  the roots of plant. It is mutualistic relationship. It means that mycorrhizae is beneficial for both organisms. Benefits:      The fungal hyphae increase the amount of nutrient such as phosphorus, copper, and other  nutrient in soil. It also help in directly absorption of these elements. On the other hand fungi absorbed nutrients from plant. Plant can grow better with mycorrhizae than the other plants. Root Epidermis:      Upper layer of root is called root epidermis which consist of  epidermal tissues. It helps in  protection, absorption as well as  interaction of plant with soil. Fungal hyphae attach with  root epidermis. Root hair:          These are thread like structure which are found on the tips of root. It helps in absorption of      nutrients f...

Major Biogeochemical Cycles: Definition, Explanation and Importance

Image
Biogeochemical cycles:     Biogeochemical cycles are those cycles in which bio elements recycle through different pathways. These cycles are complete through biological, geological and chemical processes. The major cycles are carbon cycle, nitrogen cycle and water cycle. Carbon cycle:     Carbon is major bio element. It is essential for life as it is a basic component of all organic material. It is found in the form of graphite, diamond, carbon dioxide( CO₂) and organic compound. Carbon cycle is complete in air through this process. First of all plants absorb CO₂ from atmosphere for photosynthesis. Photosynthesis is a complex process in which plants use H₂O and CO₂ to produce organic compound glucose. Animals and other organisms eat this food and incorporate carbon in their bodies. Fungi and bacteria decompose waste products of plants and animals . CO₂ is ...

Food Interactions Between Organisms: Understanding Ecological Relationships

Image
 Food Chain:                     " Flow of energy from one trophic level to other trophic level is called  food chain". In other words:             "Series of step of eating and being eaten is called food chain". For example:               The grasshopper eats grass, rat eats grasshopper, snake eats rat and then snack  is eaten by eagle. This eating process make a chain which is called food chain. Every food chain always starts from producers and finish on decomposers. Trophic level:              The levels in food chain are called trophic level. As in above example grass is first trophic level, grasshopper second trophic level, frog third and so on. There is a change of energy level in each trophic level. This change in energy state a law which says:          " The energy is transfer from...
