The United Nations Environment Programme (UNEP) has warned countries that unless they cut greenhouse gas emissions to zero in a few year, catastrophic climate changes could occur and this could endanger life on earth. The UN agency further warned that carbon emissions from human activities like burning fossil fuels should hit net zero between 2055 and 2070, or climate change could take over as a result of rising temperatures that are over 2C.
The world environmental agency also asked that methane, nitrous oxide, and hydrofluorocarbons (HFCs) which are all greenhouse gases be cut down so that between 2080 and 2100, the pre-industrial levels will have come down to net zero. It is advised that halving all greenhouse carbon emissions by the mid-century will go a long way to protect the earth and the inhabitants.
There is actually no denying the fact that there could still be some industrial gas emissions left by then, but it is expected that planting trees as a counter measure would go a long way in reducing emissions, and this will actually result in carbon neutrality. According to Achim Steiner, the UNEP executive director “an increase in global temperature is proportional to the build-up of long-lasting greenhouse gases in the atmosphere, especially carbon dioxide. Taking more action now reduces the need for more extreme action later to stay within safe emissions limits.”
One thing that environmental experts and pressure groups clamor for is that world governments must understand what needs to be done environmentally to safeguard climate changes, and what they had promised to do so far in this regard. It is time governments stopped paying lip-service to protect the environment but actually take proactive measures and do something in this regard for their peoples and for posterity.
