  • Governments must have detailed action plans and audits.
  • New and existing technologies must expand rapidly
  • Socio-economic and behavioral changes are also needed

LONDON, Oct 28 (Reuters) – Thirty-eight government scientific advisers have urged leaders of the upcoming COP26 climate conference to focus on detailed action plans, not just promises, on how to maintain the 1.5 ° temperature limit. C within reach.

In four days, governments will meet in Glasgow, Scotland, to meet this year’s deadline and commit to more ambitious emission reduction pledges, which could be the last chance for the world to take charge of keeping warming. below 2C at pre-industrial level and preferably 1.5 ° C (2.7 degrees Fahrenheit).

This week, a UN report found that current pledges will raise the world average by 2.7 degrees, and a separate report published in August warned that global warming caused by greenhouse gas emissions could exceed 1.5 degrees. degrees over the next two decades.

In a statement issued Thursday, senior scientific advisers in Argentina, Australia, the United Kingdom, Canada, Costa Rica, India, Mauritius, Mexico and Morocco said it was still possible to limit global warming to 1.5 degrees by the end of the century. . .

However, significant behavioral, technological and socio-economic changes are needed to achieve dramatic reductions in emissions by 2030 and net emissions by 2050.

The advisers said governments should develop long-term, evidence-based strategies to increase ways to reduce household CO2 emissions over the next decade, have clear and detailed policies and regular reviews of emission reduction plans.


“1.5 C (limit) is achievable if action is taken. Action must go beyond mere promise; it must be supported by clear plans and monitored, ”Patrick Vallance, UK Government Senior Scientific Adviser, told reporters.

The advisers said that a number of new and existing technology solutions need to be rapidly expanded and deployed in all sectors of the global economy.

Much more international cooperation should be done to accelerate research, development, demonstration and deployment of effective emission reduction methods and climate change adaptation solutions.

Many scientists have long called for rapid and drastic changes in society as a whole to limit global warming, including reducing meat consumption, reducing air travel, and internal combustion cars.

“I think these are things that need to happen,” Vallance said.

“There are behavioral changes that we all need. Small changes are important when combined for millions and millions of people. “

How it can be achieved is a decision of governments, not scientists, but the world should not depend on “magic technology” to save it, he said.

“The ‘green’ option should be an easy option. If there are too many obstacles, there will be little change. At the moment, some of these options are expensive. The cost premium should be lowered ”. Vallance added.
