Climate change or global warming occurs when changes in earth’s climate system result in new weather patterns that remain in place for an extended period of time, en.m.wikipedia.org.
For 2020, we are concerned with climate change given the fact that; the highest emission contributions are from industrial processes, waste, agriculture, land use and forestry. Emissions from energy are mainly through other fuel combustion whose latest values are 4.89 as absolute change from earliest 1990 to latest 2013, World Resources Institute Climate Analysis Indicators Tool (WRI CAIT) 2.0, 2015.
Human activities like deforestation, bush and rubbish burning, poor land use, swamp encroachment and destruction among many are driving global warming quite fast. Uganda’s greenhouse gas emissions grew 50% from 1990-2012, World Resources Institute Climate Analysis Indicators Tool ( WRI CAIT ) 2.0, 2015.
Greenhouse gases like carbon dioxide come from the bushes burned, rubbish burned, the factory toxic fumes and the effect of this is largely irreversible.
A greenhouse gas (GHG) is a gas that absorbs and emits radiant energy within the thermal infrared range. They cause the green house effect on planets. The primary ones are carbon dioxide, methane, water vapor and ozone, en.m.wikipedia.org.
According to United States National Research Council, Advancing the science of Climate Change, there is a strong credible body of evidence, based on multiple lines of research, documenting that climate is changing and these changes are in large part caused by human activities.
This therefore makes it largely our responsibility to curb the increasing global warming and this we can do by planting and maintain trees, not burning bushes, grass for anything, proper use of land like for planting crops so that we have more oxygen in the air which is more important than the harmful carbon dioxide.
By this, we can all have clean air to breath in like the good old days and reduce on the air pollution related issues in our society.
