Countries doing too little on warming: researchers

BONN, Germany (Reuters) - Greenhouse gas emissions in 2020 could rise to nine billion metric tons (9.92 billion tons) above what is needed to limit global warming as some countries look set to miss their emissions cut targets, a report by three climate research groups said on Wednesday.

Countries have agreed that deep emissions cuts are needed to limit an increase in global average temperature to less than 2 degrees Celsius this century above pre-industrial levels, a threshold that scientists say is the minimum required to limit devastating climate effects like crop failure and melting glaciers.
