students brainstormed and referd to trusted experts and came up with a definition for Climate Change.
Climate change is an existential threat, a threat propagated and gravely accelerated by human activity, that activity being the release of greenhouse gases—mainly carbon dioxide—that has steadily been increasing global average temperature, with its effects beginning to seep into communities across the world: affecting natural resources, ecosystems, economies and public health across the world, leading to the increase in prolonged periods of high temperature, an increase in wildfires, an increase in severe droughts, the thawing of permafrost, the acidification of our oceans and drastic sea level rise that has the potential to kill and displace billions.
Students brainstormed various causes and effects and reflected their undertstanding by sharing their views on Padlet.
Humans are increasingly influencing the climate and the earth's temperature by burning fossil fuels, cutting down rainforests and farming livestock. This adds enormous amounts of greenhouse gases to those naturally occurring in the atmosphere, increasing the greenhouse effect and global warming.
Global warming is caused by the greenhouse effect, a natural process by which the atmosphere retains some of the Sun’s heat, allowing the Earth to maintain the necessary conditions to host life. Without the greenhouse effect, the average temperature of the planet would be -18ºC.
Carbon dioxide, Methane, Nitrogen oxide, HCFCs: caused mainly by the burning of fossil fuels in electricity generation, transport, heating, industry and construction. Also caused by livestock, agriculture (mainly rice farming), wastewater treatment and landfills among others.
The oceans are also carbon sinks, absorbing up to 50 % of CO2 The problem is that, when they reach their limit, the ocean acidifies and causes death and disease among marine flora and fauna.
Human population is growing exponentially. Today, barely 250 years later, we are more than 7.7 billion and will continue growing until 2050 by at least another 2 billion. An increasingly numerous population needs more and more resources, which speeds up the increase in greenhouse gas emissions from all production processes.
Deforestation is one of the most important causes of climate change. The forests and rainforests are disappearing at breakneck speed. In the past 10 years, they have destroyed no less than 13 million hectares.
Students brainstormed on Individual solutins and as an Organization the steps to be taken.
Climate change is one of the most challenging problems that humanity has ever faced. At stake are hundreds of millions of lives, innumerable species and ecosystems, the health and viability of the economy, and the future habitability of this planet.
1. cut emissions
2. remove carbon dioxide
3. prepare and adapt
6.invest in energy efficient appliances
7.reduce water waste
9.fuel efficient vehicle
students decided on the aspects of what they can start , continue and stop if playinga role of an environmentalist.
Students actively participated in the webinar and shared their experience in the class.
they created a long list of actions and made them happen by picking up various method sto bring about a change
