Food, water, health, livelihoods already hit by climate change: IPCC

The effects of human-caused climate change are already evident on all continents and waters, the Intergovernmental Panel on Climate Change said today in a massive report, in the panel’s most plain language yet.

Climate Change 2014: Impacts, Adaptation, and Vulnerability warned of “pervasive risks” depending on the amount of future climate change — but said opportunities still exist for “effective responses,” albeit challenging ones.

Climate change has already hit agriculture, human health, water and land-based ecosystems, water supplies, and some people’s livelihoods, said the IPCC. It said the effects are evident everywhere on earth “from the tropics to the poles, from small islands to large continents, and from the wealthiest countries to the poorest.”

The world is ill-prepared for climate risks, warned the massive report, prepared and reviewed by nearly 2500 experts from 70 countries. It identified risks to people, industries, and ecosystems, from a lack of preparedness and exposure to climate-related hazards. It also said unpredictable surprises are in store for the world.

And the report placed the blame for climate change firmly on humans. “We live in an era of man-made climate change,” said Vicente Barros, Co-Chair of the group that produced the report, in a statement.

Adaptation to date focuses on reacting to past events rather than preparing for a different future, said group co-chair, Chris Field — but suggested the experience gained provides a starting point for more ambitious adaptations.

Field said opportunities exist to adapt economically and socially, if the challenges are understood. “Tackling them creatively can make climate-change adaptation an important way to help build a more vibrant world.”

The IPCC was set up in 1988 to assess the science related to climate change by the World Meteorological Organization and the United Nations Environment Programme. The report was released March 31 by a working group meeting in Yokohama, Japan.
