Climate crisis to hit sooner than feared:


Context:

A landmark draft report was recently released by the UN’s climate science advisers. The report has not yet been officially released. It is, however, designed to influence critical policy decisions.

Highlights of the report:

Climate change will fundamentally reshape life on Earth in the coming decades, even if humans can tame planet-warming greenhouse gas emissions.

Impacts: Species extinction, more widespread disease, unliveable heat, ecosystem collapse, cities menaced by rising seas — these and other devastating climate impacts are accelerating and bound to become painfully obvious by 2050.

Concern: Dangerous thresholds are closer than once thought, and dire consequences stemming from decades of unbridled carbon pollution are unavoidable in the short term.

Food insecurity: Tens of millions more people are likely to face chronic hunger by 2050, and 130 million more could experience extreme poverty within a decade if inequality is allowed to deepen.

In 2050, coastal cities on the “frontline” of the climate crisis will see hundreds of millions of people at risk from floods and increasingly frequent storm surges made more deadly by rising seas.

Water scarcity: Some 350 million more people living in urban areas will be exposed to water scarcity from severe droughts at 1.5 degrees Celsius of warming — 410 million at two degrees Celsius.

About the Scientific Advisory Board of the United Nations Secretary-General:

The UN Secretary-General announced the creation of the Scientific Advisory Board on 24 September 2013, during the inaugural meeting of the High-Level Political Forum on Sustainable Development.

  • Composition: It will comprise renowned scientists representing various fields of natural, social and human sciences.
  • The central function of the Board will be to provide advice on science, technology and innovation (STI) for sustainable development to the UN Secretary-General and to Executive Heads of UN organizations.
