Scientists are observing changes in the Earthâ€™s climate in every region and across the whole climate system, according to the latest Intergovernmental Panel on Climate Change (IPCC) Report.
Many of the changes observed in the climate are unprecedented in thousands, if not hundreds of thousands of years, and some of the changes already set in motion, such as continued sea level rise.
India will also witness the rage of climate change in the coastal region by the global warming.
Mumbai will be one of the worst affected coastal regions by global warming. In the coming times, almost 65 percent of Mumbai will be submerged. The coastal state of Goa, will also witness a considerable rise in sea levels by 2050, and areas like Mapusa, Chorao Island, Mulgao, Corlim, Dongrim will be the most affected.
Kolkata will be impacted the most by the rise of sea-level rise as most of the areas of the capital of West Bengal, including Baranagar, Rajpur Sonarpur, and regions surrounding Howrah like Santragachi, Balitikuri is feared to be drowned.
Several coastal areas of Tamil Nadu, like Chidambaram, Mahabalipuram, Kalpakkam, Marakkanam, Chunampet, Thiruporir, Velachery are at risk of getting flooded due to rise in sea level, reports say that almost 45 percent of the state capital, Chennai is expected to be impacted the most.
IPCC report provides new estimates of the chances of crossing the global warming level of 1.5Â°C in the next decades, and finds that unless there are immediate, rapid and large-scale reductions in greenhouse gas emissions, limiting warming to close to 1.5Â°C or even 2Â°C will be beyond reach.
The report shows that emissions of greenhouse gases from human activities are responsible for approximately 1.1Â°C of warming since 1850-1900, and finds that averaged over the next 20 years, global temperature is expected to reach or exceed 1.5Â°C of warming. This assessment is based on improved observational datasets to assess historical warming, as well progress in scientific understanding of the response of the climate system to human-caused greenhouse gas emissions.
The report projects that in the coming decades climate changes will increase in all regions. For 1.5Â°C of global warming, there will be increasing heat waves, longer warm seasons and shorter cold seasons. At 2Â°C of global warming, heat extremes would more often reach critical tolerance thresholds for agriculture and health, the report shows. Climate change is bringing multiple different changes in different regions â€“ which will all increase with further warming. These include changes to wetness and dryness, to winds, snow and ice, coastal areas and oceans.
