Context:
A new report issued by the UN’s Intergovernmental Panel On Climate Change paints a troubling picture of the world’s ice and oceans.
The ocean effects of climate change, from warming waters to ocean acidification to sea level rise, are already altering the weather, fisheries, and coastal communities.
The United Nation’s climate panel makes crystal clear that the planet’s oceans, snow and ice are in dire trouble and the damage is causing harm to the people who depend on them.
Even with aggressive efforts to lower greenhouse gas emissions, many nations will struggle to adapt.
Present condition of Ocean and Polar regions:
Ocean Ecosystem has been deteriorating faster than ever:
“Over the 21st century, the ocean is projected to transition to unprecedented conditions,” the IPCC report says, with the exact degree of change controlled by the levels of greenhouse gas emissions.
The IPCC report state that the ocean has already taken up more than 90% of the excess heat in the climate system since 1970, the surface is becoming more acidic, and oxygen is being depleted in the top thousand meters of the water column.
All those conditions are projected to get worse in the years ahead.
Ocean scientist and former NOAA Administrator Jane Lubchenco joins Ira to talk about the risks to the ocean, its effects on the global ecosystem, and how the ocean can also help to blunt some of the worst climate outcomes—if action is taken now.
The IPCC special report on the 1.5°C goal, for example, said it was possible to keep the rise in temperature to within 1.5°C, but for that the world would need to bring down its greenhouse gas emissions to half of its 2010 levels by 2030, and to net zero by 2050.
Net-zero is achieved when the total emissions is balanced by the amount of absorption of carbon dioxide through natural sinks like forests, or removal of carbon dioxide from the atmosphere through technological interventions.
Way Forward: What can we do?
Conclusion:
The new IPCC Special Report on the Ocean and Cryosphere makes clear that no action on climate change is not a viable path forward.
The United Nations Climate Action Summit, which convened intended to do that the goal of the meeting was to identify realistic plans toward reducing greenhouse gas emissions by 45 per cent during the next decade and further to net-zero by 2050.
Seventy-seven countries announced efforts toward net-zero emissions by 2050. Multiple businesses voiced intentions to follow Paris Agreement targets to reduce emissions.
During the same time, trees and forests absorbed almost 11.2 billion tonnes of carbon dioxide every year from the atmosphere.
The sum total of these processes meant that land, and the vegetation on it, was removing about 6 billion tonnes of carbon dioxide from the atmosphere annually.
Widespread climate strikes, led largely by young people, are also a sign of a broader social response to climate change.
