What is "Global Warming"  what are the causes, how will it affect us and what we can do about it!

​What is Global Warming? Definition: 
The long-term increase in Earth's average surface temperature, primarily driven by human activities that release greenhouse gases into the atmosphere.

Not just warming: 
Global warming is a part of the broader issue of climate change, which includes other shifts in weather patterns such as precipitation, extreme events, and sea level rise.

Causes of Global Warming - Greenhouse gases: 
Gases like carbon dioxide (CO2), methane, nitrous oxide, and fluorinated gases trap heat radiating from Earth, preventing it from going into space. This is known as the "greenhouse effect."

Human activities:
Burning fossil fuels (coal, oil, natural gas): This activity is the biggest contributor to greenhouse gas emissions.

Deforestation:
Trees absorb CO2. Cutting them down reduces this natural carbon sink and releases stored carbon. Industrial processes: Manufacturing of cement, chemicals, etc., releases greenhouse gases.

Agriculture:
Livestock farming produces methane, and fertilizers release nitrous oxide.

Effects of Global Warming Rising temperatures: 
The obvious one! Global temperatures are already about 1 degree Celsius warmer than pre-industrial levels and the rate is accelerating.

Melting ice: 
Glaciers, polar ice caps, and sea ice are melting faster than ever, leading to sea level rise.

Sea level rise: 
Coastal cities and low-lying areas are threatened by inundation and erosion.

Extreme weather events: 
More frequent and intense heatwaves, droughts, floods, wildfires, and storms.

Ocean acidification: 
Increased CO2 absorption makes seawater more acidic, harming marine life.

Loss of biodiversity: 
Climate change disrupts ecosystems, leading to species decline and extinction.

Human impacts: 
Food and water insecurity, displacement due to rising seas, health risks.

What Can We Do?

Shift to renewable energy: 
Solar, wind, geothermal, and other clean sources reduce fossil fuel dependence.

Energy efficiency: 
Using less energy through insulation, smarter appliances, and behavior changes.

Sustainable transportation: 
Electric vehicles, public transport, biking, and walking.

Protecting forests: 
Stop deforestation and promote reforestation to maintain carbon sinks.

Sustainable agriculture: 
Practices that reduce emissions and promote healthier soils.

Individual actions: 
Making choices about diet, transportation, and energy use all contribute.
​
Policy change: 
Pushing leaders to enact policies for large-scale energy shifts and emissions reductions.

Important Notes Scientific consensus: 
The overwhelming majority of scientists agree that global warming is real, human-caused, and a serious threat.

The time to act is now: 
The longer we wait, the more severe the effects and the more challenging it will be to address.
