Climate change effects will always remain with us. Climate change is a change in global or regional climate patterns, usually attributed to the increased levels of atmospheric carbon dioxide caused by human use of fossil fuels and the release of greenhouse gases into the air. Such changes in the climate patterns often called global warming, manifest in unusual heat waves, flash floods, ocean acidification, desertification and its resultant food insecurity, rise in ocean level, among others.
The cause of the afore-mentioned have been traced to human activities such as depletion of the ozone layer, indiscriminate blockage of water channels with wastes that are not bio-degradable such as plastic bottles and polythene bags. This is in addition to the industrial pollution of the environment as well as gas emission and flaring.
It has been argued that global emissions of carbon dioxide have increased by almost 50% since 1990. To add to this, United Nations has also claimed that the atmospheric concentrations of carbon dioxide, methane, and nitrous oxide have increased to levels unprecedented in at least the last 800,000 years. Carbon dioxide concentrations have increased by 40% since pre-industrial times, primarily from fossil fuel emissions and secondarily from net land use change emissions. The ocean has absorbed about 30% of the emitted anthropogenic carbon dioxide, causing ocean acidification.
The effect of all these is the increase in danger pose to human existence. The sea level continues to rise, there has been several earthquakes, tornadoes, floods in a magnificent proportion leading to loss of lives and properties. Despite this, it is still possible to contain the effect of climate change. According to the United Nations, there are multiple mitigation pathways to achieve the substantial emissions reductions over the next few decades necessary to limit, with a greater than 66% chance, the warming to 2ºC – the goal set by governments.
Sustainable Development Goal 13, aims at encouraging everyone to take urgent action to combat climate change and its impacts.
To achieve this goal by 2030, we need to start the process now and sustain the efforts through the years to come.
Watch against personal attitudes that escalate climate issues: The way we live our daily lives has a lot of impact on the society. The way we dispose wastes means a lot. Blocking the drainages with polythene bags and plastic water bottles; indiscriminate felling of trees; weak regulatory and control of the environment including industrial wastes and Mining activities; are just a few activities that are capable of compromising safe environment.
Start an advocacy group: The least you can do is to start a climate action advocacy group in your area to help neutalise the dangers of climate change.
