Why there is a need to keep global warming within 1.5 degree celsius

The Intergovernmental Panel Of Climate Change Report looks into the consequences of the temperature jumping up to 1.5 degrees C and 2 degrees C above the pre-industrial era levels.

The report says the average warming of 1.5-degree Celsius produces a high risk of heat waves, rain falls, coral bleaching, and sea level rise and other issues. According to the Paris agreement, 195 countries agreed to keep up the global temperature below 2-degree Celsius level and make efforts to limit the warming under 1.5-degree Celsius.

 Because of the pollution causing from human actiities, the global average temperature raised to 1-degree Celsius. There is a 0.2-degree Celsius increase in every decade. If this trend continues world would reach 1.5 degree Celsius y 2040. Strong international cooperation and high efforts from countries is needed to reduce emissions rapidly in the coming decade to hold the temperature at 1.5 degree Celsius. There are some measures to be taken by the countries according to the report. That is, shift to low or zero emission power generation, changing food system systems such as moving away from land intensive animal products, electrifying transport, developing green infrastructure and improve energy efficiency by smart urban planning.
