Global temperatures have warmed significantly since 1880, the beginning of what scientists call the "modern record." At this time, the coverage provided by weather stations allowed for essentially global temperature data. As greenhouse gas emissions from energy production, industry and vehicles have increased, temperatures have climbed, most notably since the late 1970s. In this animation of temperature data from 1880-2011, reds indicate temperatures higher than the average during a baseline period of 1951-1980, while blues indicate lower temperatures than the baseline average.
A report by the United Nations Development Programme (UNDP) indicates that ocean surface water warming limits the upward movement of nutrients and this can cause a decrease in fish production.
If fossil fuel infrastructure is not rapidly changed, the world will 'lose for ever' the chance to avoid dangerous climate change
PRETORIA, 14 November 2011 (IRIN) - Soaring temperatures and erratic rains brought on by a changing climate may radically alter water flows in the world’s major river basins, including the Limpopo in southern Africa, forcing people to give up farming in some areas, says a new study.

Failures of urban planning are putting lives, infrastructure and businesses at risk as weather shocks – like the floods now surging through Bangkok – become more frequent as a result of climate change, urban planning and climate experts say.
Droughts and rising sea levels could reverse efforts to improve living conditions of world's poorest people, report warns
WASHINGTON, Oct 27 (Reuters) - The world's governments and relief agencies need to plan now to resettle millions of people expected to be displaced by climate change, an international panel of experts said on Thursday.
Global temperature rise could exceed "safe" levels of two degrees Celsius in some parts of the world in many of our lifetimes if greenhouse gas emissions continue to increase, two research papers published in the journal Nature warned.
