Climate Action

PSGR KRISHNAMMAL NURSERY AND PRIMARY SCHOOL Climate action: “Be the change you wish to see in the world ” Introduction: We are lucky to be a part of the solution in climate action project from PSGR Krishnammal Nursery and Primary School, Peelamedu, Coimbatore, Today’s situation in this scenario we want to protect the environment but we have to change the situation to create an environment that protect us for future… What is climate change? Climate change describes a change in the average conditions such as temperature and rainfall in a region over a long period of time. NASA scientists have observed Earth's surface is warming, and many of the warmest years on record have happened in the past 20 years. What is your definition of climate change? Climate change is a change in the usual weather found in a place. This could be a change in how much rain a place usually gets in a year. Or it could be a change in a place's usual temperature for a month or season. What causes climate change ? *The main problem is pollution and deforestation Change the natural climate into drastic… *The cause of current climate change is largely human activity, like burning fossil fuels, like natural gas, oil, and coal…. Burning these materials releases greenhouse gases into Earth's atmosphere… *Due to the emissions of green house gases the climate change take place .The water level in dams ,river ,ponds decreased…people are not getting enough water to drink…In future it lead to drought… *Forest fire happen in some places… *We are not getting experience proper rain fall… What is your personal connection to climate change? The state of Tamil Nadu is a weather-sensitive pocket that experiences different flavors of seasons throughout the year. *Pre -Monsoon. *Southwest Monsoon. *Post Monsoon or Northeast Monsoon. *Winter season. *Summer season. Tamil Nadu fills under Tropical savanna climate and smaller portions of the state fall under Humid subtropical climate; the climate of the state ranges from dry subhumid to semi-arid. We are living in Coimbatore, here the climate is always very warm and cool climate because the hill station The queen of Hill Nilgiri (Ooty) is located near the Coimbatore district of Tamilnadu… We feel very pleasant weather over a long period in all season… Week 1 (September 27 to October 03) Action report: * Online class explanation of PowerPoint presentation of what is climate change definition? *What are the causes of climate change? Given through Google meet for all classes from KG to grade V *Students activity regarding climate change given… ✓Poster making ✓Drawing ✓Placard making ✓Students voice to protect climate change …Collecting the students view regarding causes of climate change in local and making long list of it . ✓Video explanation of climate change in world wide…

Climate change effects week 2


Effects of Climate change on weather:

Rising global average temperature is associated with widespread changes in weather patterns. Scientific studies indicate that extreme weather events such as heat waves and large storms are likely to become more frequent or more intense with human-induced climate change.

Effects of Climate change on Plants:

Climate change can affect agriculture in a variety of ways. Beyond a certain range of temperatures, warming tends to reduce yields because crops speed through their develop- ment, producing less grain in the process. And higher tem- peratures also interfere with the ability of plants to get and use moisture.

Effects of Climate change on Agriculture:

Agriculture is extremely vulnerable to climate change. Higher temperatures eventually reduce yields of desirable crops while encouraging weed and pest proliferation. Pests management become less effective, meaning that higher rates of pesticides will be necessary to achieve the same levels of control.

Effects of Climate change on Health:

Climate change increases the risk of illness through increasing temperature, more frequent heavy rains and runoff, and the effects of storms. Health impacts may include gastrointestinal illness like diarrhea, effects on the body’s nervous and respiratory systems, or liver and kidney damage

Effects of Climate change on Environment:

Climate change may aggravate erosion, decline in organic matter, salinization, soil biodiversity loss, landslides, desertification and flooding. The effect of climate change on soil carbon storage can be related to changing atmospheric CO2 concentrations, increased temperatures and changing precipitation patterns.

Global warming:

Global warming, the gradual heating of Earth’s surface, oceans and atmosphere, is caused by human activity, primarily the burning of fossil fuels that pump carbon dioxide (CO2), methane and other greenhouse gases into the atmosphere. …


Drought is a prolonged dry period in the natural climate cycle that can occur anywhere in the. world. It is a slow-onset disaster characterized by the lack of precipitation, resulting in a water. shortage. Drought can have a serious impact on health, agriculture, economies, energy.

Melting glacier:

Melting Glaciers. A glacier is a big chunk of ice that is created from falling and accumulated snow over a period of time. ... Due to heat changes, especially to relatively high temperatures, the Glacier melting occurs – a process where the ice changes from solid to liquid or water.

Sea level increase:

As the rising ocean erodes the shoreline and floods the areas in which coastal animals live, animals like shorebirds and sea turtles will suffer. Their delicate nests may be swept away by flooding, an especially big problem for endangered animals like sea turtles that can’t afford to lose any offspring.

Wild fire:

Common causes of wildfires include lightning, human carelessness, arson, volcano eruption, and pyroclastic cloud from active volcano. Heat waves, droughts, and cyclical climate changes


Wild habitats affect:

When a habitat is destroyed, the carrying capacity for indigenous plants, animals, and other organisms is reduced so that populations decline, sometimes up to the level of extinction. Habitat loss is perhaps the greatest threat to organisms and biodiversity.

Decline of water level:

Climate change impacts the water cycle by influencing when, where, and how much precipitation falls. … Increasing global temperatures causes water to evaporate in larger amounts, which will lead to higher levels of atmospheric water vapor and more frequent, heavy, and intense rains in the coming years.

Solution for climate change:

Tree plantation:

Everybody needs a friend." "The true meaning of life is to plant trees, under whose shade you do not expect to sit." "Love is like a tree, it grows of its own accord, it puts down deep roots into our whole being." "Until you dig a hole, you plant a tree, you water it and make it survive, you haven't done a thing.

Climate change causes and effects globally


Climate change causes and effects globally

We are from PSGR Krishnammal Nursery and Primary School Peelamedu, Coimbatore, Tamil Nadu, India. Our  Children discuss about effects of Climate change and causes of Climate change with Climate Action Project- SSIPS, Salem,IndiaTuesday, October 12 · 3:00 – 4:00pmAs Google meet video call conference meeting…

Globally from Malaysia, Indonesia the Educators and Students take part in the international collaboration video Meeting and share their views and thoughts about climate change effects and causes…

Indian Public school, Erode, share their Power point presentation with us…

 Our children share their point about Climate change effects and causes In South Asia:

*The effects of climate change on South Asia include steady sea level rise, increased cyclonic activity, and changes in ambient temperature and precipitation patterns. Increased landslides and flooding are projected to have an impact on states such as Assam. 

*Ongoing sea level rises have already submerged several low-lying islands in the Sundarbans.

*Displacing thousands of people. The first among the countries to be affected by severe climate change is Bangladesh.

* Sea level, temperature, and evaporation are increasing, and the changes in precipitation and cross-boundary river flows are already beginning to cause drainage congestion.

*There is a reduction in freshwater availability, disturbance of morphological processes, and a higher intensity of flooding.

*Regarding local temperature rises, the IPCC figure projected for the mean annual increase in temperature by the end of the century in South Asia is 3.3 °C with the min-max range as 2.7 – 4.7 °C. The mean value for Tibet would be higher with mean increase of 3.8 °C and min-max figures of 2.6 and 6.1 °C respectively which implies harsher warming conditions for the Himalayan watersheds. India's GDP could decline by up to 9%, due to shifting growing seasons for major crops such as rice, production of which could fall by 40%. Around seven million people are projected to be displaced due to, among other factors, submersion of parts of Mumbai and Chennai, if global temperatures were to rise by a mere 2 °C (3.6 °F)

Effects of climate change on human health:

*The human body requires evaporative cooling to prevent overheating, even with a low activity level. With excessive ambient heat and humidity, adequate evaporative cooling does not take place. Human thermoregulatory capacity is exceeded.

*Human response to heat stress can be hyperthermia, heat stroke and other harmful effects. Heat illness can relate to many of the organs and systems including: brain, heart, kidneys, liver, etc.




Impact on natural resources

Drinking water

*Global Health Corps reports that when interruptions in the regular water supply, "forces rural and impoverished families to resort to drinking the dirty, sediment-and-parasite-laden water that sits in puddles and small pools on the surface of the earth.

*When there is an adequate amount of drinking water, humans drink from different sources than their livestock. However, when drought occurs and drinking water slowly disappears, catchment areas such as streams and depressions in the ground where water gathers are often shared between people and the livestock they depend on for financial and nutritional support, and this is when humans can fall seriously ill. *Although some diseases that are transferred to humans can be prevented by boiling the water, many people, living on just a litre or two of water per day, refuse to boil, as it loses a certain percentage of the water to steam.

Fresh water

*As the climate warms, it changes the nature of global rainfall, evaporation, snow, stream flow and other factors that affect water supply and quality. Freshwater resources are highly sensitive to variations in weather and climate. Climate change is projected to affect water availability. In areas where the amount of water in rivers and streams depends on snow melting, warmer temperatures increase the fraction of precipitation falling as rain rather than as snow, causing the annual spring peak in water runoff to occur earlier in the year. This can lead to an increased likelihood of winter flooding and reduced late summer river flows. Rising sea levels cause saltwater to enter into fresh underground water and freshwater streams. This reduces the amount of freshwater available for drinking and farming. Warmer water temperatures also affect water quality and accelerate water pollution.

Impact on Nutrition:

*Another area of concern is the effect of climate change on the nutritional content of food for human consumption. Studies show that increasing atmospheric levels of CO2 have an unfavourable effect on the nutrients in plants. As the carbon concentration in the plant's tissues increase, there is a corresponding decrease in the concentration of elements such as nitrogen, phosphorus, zinc and iodine. Of significant concern is the protein content of plants, which also decreases in relation to elevating carbon content.

*IrakliLoladze explains that the lack of essential nutrients in crops contributes the problem of micronutrient malnutrition in society, commonly known as “hidden hunger”; despite adequate caloric intake, the body still is not nutritionally satisfied and therefore continues to be “hungry”. This problem is aggravated by the rising cost of food, resulting in a global shift towards diets which are less expensive, but high in calories, fats, and animal products. This results in undernutrition and an increase in obesity and diet-related chronic diseases.

*Countries worldwide are already impacted by deficiencies in micronutrients and are seeing the effects in the health of their populations. Iron deficiency affects more than 3.5 billion people; increasing maternal mortality and hindering cognitive development in children, leading to education losses. Iodine deficiency leads to ailments like goitre, brain damage and cretinism and is a problem in at least 130 different countries. Even though these deficiencies are invisible, they have great potential to impact human health on a global scale.

*Small increases in CO2 levels can cause a CO2 fertilization effect where the growth and reproduction abilities of C3 plants such as soybeans and rice are actually enhanced by 10-20% in laboratory experiments. This does not take into account, however, the additional burden of pests, pathogens, nutrients and water affecting the crop yield.

Climate action


Climate Action week 6

Topic: Students take action and bring change at school, home, community and the government Students Action : In school: Our student give voice to zero literless campaign .we should not pollute the Environment . We should follow 5r concept Reduce Recycle,Reuse, Recover, Replace. Our Children collect the waste and convert into the useful material to reuse the product like water bottle as gardening purpose, craft work material from CD, paper work… In home: Our children plant a saplings in their home to prevent climate change… Homes and commercial buildings account for about a third of the country’s greenhouse gas emissions, because it takes energy to heat and cool them and to power all the gadgets we’ve got plugged in. Old-style incandescent light bulbs in your house, go buy LEDs instead. And stop electronic devices such as televisions and laptop computers from sipping power all night long. Plugging them into a power strip makes it easy to disconnect them at night, and a “smart power strip” The solar panels and heater renewable energy resources used in home. In Community: Solar renewable energy resources light plant in the streets as street lamp,parks. first and foremost, reduce their consumption; recycle and compost whenever possible; ask their apartment/workplace/church etc. to implement recycling and/or composting; if composting is not an option where they live, that talk to their local representatives about developing a composting program. Our children secure pet animals,birds by building a shed,nest and safeguard them. In government: India’s Prime Narendra Modi has set his country a target of net zero greenhouse gas emissions by 2070, a significantly later deadline than many other countries attending the Glasgow climate summit. India also set itself a deadline of 2030 to reduce its emissions by one billion tonnes.
