Global Warming caused by Human Intervention with Environment is dangerously close to spiralling out of control.
We can see the evidence in the latest report of the UN Climate panel, where they have given a landmark report on the warning the world is already sure to face future climate disruption for decades if not centuries to come.
With no doubt in the report from the Intergovernmental Panel on Climate Change (IPCC), scientists have blamed Humans for this catastrophe. To reduce its impact, there is a need for rapid action to cut down greenhouse gas emissions.
UN Secretary-General Antonio Guterres described the report IPCC as “Code red for Humanity”.
We learned earlier that the average global temperature is likely to reach or cross the 1.5-degree Celsius warming threshold within 20 years.
India’s takeaway from Climate Change warning
As per the latest projections about India, the Warming over India is projecting to be in sync with the global average.
• Due to this, India is expecting to increase the frequency and severity of hot extremes. Due to growing heatwave conditions, forest fire incidents may rise.
• An increase in rainfall would be more severe over southern parts of the country. At the same time, around rain could increase by approximately 20% on the southwest coast.
• Snowline elevation will rise as glacier volume decreases, resulting in regional mean sea levels growing.
• Rising sea levels inundate low-lying coastal regions and threaten the local communities and the biosphere.
• The Sundarban delta, the world’s largest mangrove biosphere, is experiencing a 30-millimetre rise in sea level every year and subsequent significant land erosion.
If not checked, the crisis may turn severe shortly and also threaten Kolkata.
Sign of Global Warming on Greenland Ice Sheet
Greenland experienced a record-setting temperature of more than 20 degrees after rain comes during the summer season at northern Greenland.
Danish scientists on Monday said it was possibly the first time the rainfall at the highest point on the Greenland ice sheet, and it may be driven by climate change.
Rain was observed on August 14 for several hours at a measuring post more than 3000 meters up to the sheet, per the US Snow and Ice Data Center report.
Researcher at Danish Meteorological Institute, Martin Stendel, said, “this is an extreme event as it may never have happened before” he added the temperatures have risen above freezing at the peak of the sheet only nine times in the past 2000 years.
Giant Iceberg A74 was narrowly avoiding colliding with the Antarctica Ice shelf.
Earlier this month, a chunk more significant than the iceberg A-74 or 1270 square kilometres iceberg was knocked off the ice-shelf.
The iceberg broke off Brunt in late February this year. Strong ocean prevents it from floating westward into the Wendell Sea, and it hovered close to the shelf’s west coast for six months.
ESA’s Mark Drinkwater said, “If the berg had collided more violently with this piece, it could have accelerated the fracture of the remaining ice bridge, causing it to break away.”
The breaking of icebergs and the rapid melting of polar ice caps is attributed to the Global Warming of the land and sea.
These events result in an unprecedented rise in sea level and change in ocean currents, according to Samrat Sengupta, programme director, climate change and renewable energy, Centre for Science and Environment, a Delhi-based non-profit.
Talks resume protecting biodiversity.
UN negotiators have resumed their worldwide plan to protect nature and species for the next decade.
The draft propitiated on Global Biodiversity Framework aims to conserve at least 30% of the world’s land and oceans.
It will push nations to eliminate plastic waste and cut pesticides used by at least two thirds.
They have published a draft of the new agreement and proper 21 targets for 2030. The main takeaway from it is –
• At least 30% of the land and seas should be conserved through equitably managed measures.
• Reduce pesticides used by 2/3.
• Eliminate the discharge of plastic waste.
• Required or eliminate incentives harmful to biodiversity by at least $50b a year.
• An increase in funding for the conservation of nature to at least $200b a year.
Net-Zero Emissions
The idea of net-zero emissions has gotten much traction among global climate negotiators over the last year, and some agreement on it is expected at the UN Climate Change Conference in Glasgow in November.
Net-zero can be understood by balancing the number of greenhouse elements produced and the number of greenhouse elements removed from the atmosphere.
We reach net-zero when the amount we add is no more than the amount is taken away.
What is the net-zero campaign?
For the last two years, an aggressive campaign has been going on for every country to assign a net-zero target year.
For achieving the Paris Climate Agreement target, net zero-emission is mandatory. At Glasgow, we can see Joe Biden making to have an agreement on net zero.
137 of 192 countries part of the UN Climate Convention representing 80% of global emissions have committed to net zero emissions targets.
They include the world’s two largest emitters – the US and China. The third biggest emitter, India, is yet to announce a net-zero target year.
For a developing nation like India, it does not seem an easy way to go as it is believed that net-zero would slow down its economic growth and hamper its poverty alleviation programs.
