The United Nation’s Intergovernmental Panel on Climate Change (IPCC) issued a report on Monday with a warning to limit the global warming to 1.5ºC above pre-industrial levels. This would require rapid, far reaching and unprecedented changes in all aspects of society, the IPCC report said. If the global temperature rises by 2ºC, there is a threat of deadlier heatwaves in India and Pakistan. The temperature rise will also increase food shortage and loss of cereal crops, poverty and vector-borne diseases like Dengue and Malaria.
Here Are More Details About The IPCC Report On Global Warming
- The report specifically stated Karachi and Kolkata to be under the major threat of heatwaves which will be equivalent to the deadly 2015 heatwaves. Climate change is significantly contributing to increased heat-related mortality.
- Human activities cause around 1.0°C of global warming above pre-industrial levels which is estimated to reach 1.5°C between 2030 -and 2052 if it continues to increase at the current rate.
- Estimated anthropogenic global warming is currently increasing at 0.2°C. Even an increase of 0.5ºC in the global warming may adversely affect the human health all over the globe.
- Climate-related risks to health, livelihoods, food security, water supply, human security, and economic growth are projected to increase with global warming of 1.5°C and increase further with 2°C.
- Countries in the tropics and Southern Hemisphere subtropics would experience the largest impacts on economic growth due to climate change, the IPCC report said.
- Arctic Ocean would be free of sea ice in summer once per century with global warming of 1.5°C, compared with at least once per decade with 2°C.Coral reefs would decline by 70-90 percent with global warming of 1.5°C,with 2°C, they will be wiped out.
- Global net emissions of carbon dioxide should fall by 45% from 2010 levels by 2030 and reach “net zero” around 2050 to keep the warming around 5°C.
- Lowering emissions would require widespread changes in energy, industry, buildings, transportation and cities.
- The full name of the report is- Global Warming of 1.5°C, an IPCC special report on the impacts of global warming of 1.5°C above pre-industrial levels and related global greenhouse gas emission pathways, in the context of strengthening the global response to the threat of climate change, sustainable development, and efforts to eradicate poverty.
- The Intergovernmental Panel on Climate Change (IPCC) is the leading international body for the assessment of climate change with 195 countries as its members.
