Science Assessment
and Analysis

Climate science is highly complex and the policy implications are not always clear. We make the latest climate science easily accessible for stakeholders in the international climate change arena.

Ocean acidification

Besides increases in temperatures, the world’s oceans also take up CO2, leading to a lowering of pH-levels in the water. This process is especially relevant to marine ecosystems and coral reefs, which are very sensitive to changes in ocean chemistry. Strong ocean acidification depresses metabolic rates in some organisms and reduces the ability of species to sequester calcium required for building shells and skeletons, or even leads to dissolving existing coral reef structures. We assess greenhouse-gas emission scenarios regarding the possibility to prevent the worst of the projected effects of ocean acidification.

Regular food shortages in Sub-Saharan Africa….shifting rain patterns in South Asia leaving some parts under water and others without enough water for power generation, irrigation, or drinking….degradation and loss of reefs in South East Asia resulting in reduced fish stocks and coastal communities and cities more vulnerable to increasingly violent storms….these are but a few of the likely impacts of a possible global temperature rise of 2 degrees Celsius in the next few decades that threatens to trap millions of people in poverty, according to a new scientific report released today by the World Bank Group.
