Global warming

While the calendar stays the same, the seasons seem to be changing due to ever increasing temperature on the planet earth. Lately, the Metrological Department has predicted the vanishing of the spring season altogether in Pakistan as global warming has turned to a dangerous level in the world. Decades of data collected around the world indicates that spring has been springing earlier and earlier in the year. Like Pakistan, other countries around the Equator are also at risk of experiencing dangerous weather patterns due to a persistent rise in mercury.

New research shows that summer conditions are now arriving earlier in Asia and Europe than four decades ago. The fact that warming seems to be changing the timing of the seasons should concern us. Scientists predict that the temperature of the world’s oceans will go up by three degrees Celsius by 2050. Climate change is drastically and rapidly altering ecosystems, agriculture and weather fluctuations all over the world. The life cycles of most plants and animals are critically tied to seasonal changes in temperature, precipitation, and light. The timing of bird migration and breeding is sensitive to changes in temperature, and global warming would be expected to lead to an earlier onset of those activities in the spring.

These changes are directly making an impact on human life in affected regions of the world. The warming trend over recent decades has already contributed to increased morbidity and mortality in many regions of the world. There are numerous areas that affect directly from climate change and ultimately bring in indirect affect for human life and eco-system on earth. A global assessment of potential effects of climate change on world food supply suggests that doubling of the atmospheric carbon dioxide concentration will lead to only a small decrease in global crop production.

The better way is to take some preemptive steps to at least delay such affects to touch this part of the earth. Unfortunately the government can be bracketed as most oblivious government in the world of the effects of climate change. While other countries are adapting to climate change and abiding by climate conventions, Pakistan has largely neglected this pressing issue so far. We need to decrease our dependence on fossil fuels and find sustainable solutions like increasing the capacity and number of hydroelectric power plants, building more nuclear power plants and relying on renewable resources to solve our energy crisis. Domestic, agricultural and industrial waste needs to be recycled and disposed of properly. One of the most pervasive forms of pollution in the country is the growing number of cars on the roads, most without catalytic converters. The best way to reduce motor vehicle caused pollution is by setting up safe and efficient public transport networks. Hopefully Pakistan will launch environmental initiatives and become greener by then.
