This World Bank report is a stark reminder that climate change affects everything and spells out what the world would be like if it warmed by 4°C, which is what scientists are nearly unanimously predicting by the end of the century, without serious policy changes.

The purpose of this paper is to provide an overview of adaptation to climate the impact in Bangladesh. The combination of being located at the confluence of three major rivers, and being extremely low lying, Bangladesh is vulnerable to extreme weather events such as typhoons and flooding.

The policy brief, titled "Recalibrating food production in the developing world: global warming will challenge more than just the climate," notes that climate impacts are more complex than simply heat and water tolerance for plants, and that there are feedback cycles in how natural resource are managed and their resilience to climate change.

This new WHO report provides scientific information on the connections between weather and climate and major health challenges. These range from diseases of poverty to emergencies arising from extreme weather events and disease outbreaks.

Developing countries are not yet well adapted even to current climate risks: floods, droughts and storm. Yet those risks are becoming harsher as the world warms, climate extremes become more intense, and the oceans rise – the consequences of human-caused greenhouse gas emissions.
