President Donald Trump on First June made his final call to pull the United States out of the Paris climate agreement.The deal was hammered out over weeks of tense negotiations in December 2015 and weighs in at 31 pages,Signed by all but two countries (Syrian and Nicaragua), is a broad framework designed to nudge nations to prevent catastrophic climate change.Though 195 countries have agreed to it. But there’s also no defined punishment for breaking it. The idea is to create a culture of accountability.
The backbone is the global target of keeping global average temperatures from rising 2°C (compared to temperatures pre-industrial revolution) by the end of the century. Beyond 2 degrees, we risk dramatically higher seas, changes in weather patterns, food and water crises, and an overall more hostile world.
The world is getting hotter, and so does Karachi, Yes! humans are responsible. That’s the short version.Temperatures over land and ocean have gone up 0.8° Celsius (1.4° Fahrenheit).
The glaciers and ice sheets around the world are melting. Satellite observations since the 1970s have shown warming in the lower atmosphere. There’s more heat in the ocean, causing water to expand and sea levels to rise. These are all signs that the Earth really is getting warmer — and that it’s not just a glitch in the thermometers.
Karachi has been once again invaded by heat wave and impact of the global warming is very much clear for the people Karachi-much more by the research result of an eminent Professor in the University of Karachi.
Temperatures like42°Cand43°Chave frequently occurred in Karachi without any casualties;even 46°C and 47°C inthe1970sand1980s.
On June 23, 2007, the maximum temperature in Karachi was 44°C with a maximum heat index of 52.3°C. The maximum temperature a day earlier was 42°C and a day later it was 40°C.Yet there were no heatstroke cases, despite widespread power failures for several days due to a severe storm.
On June 20, 2015, the maximum temperature was 44.8°C with a maximum heat index of 49.4°C, and this heat wave became a death wave for many people in Karachi. The lack of electricity must have played some part in it.
In such conditions staying indoors and keeping rehydrated and fedprotects againstsuchheatbutdaily-wage-earners, vendors, house-maids etcetera cannot do so. Back in the 1960s and most of the 1970s, restaurants and eateries used to remain open during Ramazan. For a labourer doing strenuous work outdoors in 40°C+ temperature, any amount of water and fluids taken as Sehari cannot keep him effectively hydrated over the 15-hour fast, making him highly vulnerable to heatstroke. All such people had benefitedfrom these eateries.”
The understanding from the above is clear that the impact of climate change is very hard so the whole world should stick to Paris Climate Deal for better, pleasant and livable planet for all.
