The CDER participates in the approval of the special report of the UN Panel on Climate Change (IPCC) on the consequences of global warming of 1.5°C compared to the pre-industrial era
In his capacity as vice chair of the working group 1 of the UN Panel on Climate (IPCC: Intergovernmental Panel on Climate Change), Professor Noureddine Yassaa, director of the Renewable Energy Center, participated in the session that was dedicated to the approval of the special report of the IPCC on the impacts of global warming of 1.5°C compared to the pre-industrial era. The session was held in Incheon, South Korea.
The summary for decision makers has been approved on Saturday 6 October 2018 by 196 IPCC member countries. This report entitled “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 change, sustainable development and efforts to eradicate poverty », demonstrates that it is still possible to limit global warming of 1.5 °C on condition of operating an unprecedented multi sectorial transition, Accelerated and significant.
Limiting global warming to 1.5 °C rather than 2 °C enables populations and ecosystems to adapt and remain below relevant risk thresholds, thereby enhancing their resilience to climate change.
This report highlights that the impact of global warming at 1.5 °C will be evident in the increase in extreme weather events, torrential rains, rising sea levels, shrinking Arctic sea ice, drought, and heat waves. These effects Will Be even more dramatic at 2 °C.
This report underscores the numerous negative consequences of climate change that can be averted by restricting global warming to 1.5°C rather than 2°C or higher. In addition, by the year 2100, global sea level rise will be at least 10 cm lower if warming is limited to 1.5°C compared to when it is limited to 2°C .The probability of the Arctic Ocean being free of sea ice in summer would be once in a century event, if global warming is limited at 1, 5 °C, but could occur once per decade if warming is limited at 2 °C. 70 to 90% of coral reefs would disappear if global warming is constrained to 1,5 °C compared to larger loses - almost all (>99%) that would be wiped out at 2 °C . The risk of lasting or irreversible changes is heightened by a warming of 1.5 °C or more, on biodiversity as evidenced by the potential extinction of certain ecosystems in the environment.
The reduction of global warming to 1.5 °C, rather than 2 °C, will reduce the significant consequences on ecosystems, health, and the well-being of populations. This will aid in the realization of the sustainable development objectives outlined in the United States’ 2030 calendar.
It was indicated in this report that the reduction of global warming at 1, 5 °C necessitates fast and large-scale transitions in the fields of land use planning, energy, industry, construction, transport and urban planning. By 2030 Global net anthropogenic carbon dioxide (CO2) emissions should be reduced of approximately 45% compared to the levels of the year 2010, and it would be necessary to attain a net zero emissions around the year 2050, which signifies that the residual emissions should be offset by removing CO2 from the atmosphere.
This report provides decision-makers and professionals with the necessary information to make decisions about climate change, while also considering the needs of local specificities and the needs of populations. It will enable the identification of strategies for a resilient and long lasting the social and economic development.
This historical report comes in response to the invitation of the Paris Agreement on climate change was officially released on October 8, 2018 and it will support the Tolanoa dialogue at the COP24 in Katowice, Poland on climate change, next December.
