The developing world and emerging markets are among the most exciting places for climate policy and innovation, according to a former White House official who advised the Obama administration in the run-up to the COP20 summit in Lima, Peru.

Some developing nations are already looking at climate technologies as a major economic opportunity, said Kelly Sims Gallagher, now a professor and director of the Center for International Environment and Resource Policy at Tufts University in the United States. She made the remarks on the opening day of Science Policy Research Unit’s (SPRU) 50th anniversary conference at Sussex University in Brighton, UK.

Developing countries have several advantages that put them in a good position to innovate, Gallagher told SciDev.Net. There is less existing built infrastructure, which tends to create a lock-in effect, making it difficult to adopt cleaner and more efficient technologies. And the cost of renewables and other energy efficiency technologies is now low enough to make investing in them a sensible economic decision, she said.

The past 12 months have seen an intensification of countries’ efforts to meet UNFCCC safeguard requirements as they move towards REDD+ implementation, and the UN-REDD Programme has been stepping up its technical assistance to meet this upsurge in demand for support on safeguards.

Signs of warming appear as early as 1830 say researchers, whose analysis will help build accurate baseline of temperature before influence of human activity.

Continents and oceans in the northern hemisphere began to warm with industrial-era fossil fuel emissions nearly 200 years ago, pushing back the origins of human-induced climate change to the mid-19th century.

The first signs of warming from the rise in greenhouse gases which came hand-in-hand with the Industrial Revolution appear as early as 1830 in the tropical oceans and the Arctic, meaning that climate change witnessed today began about 180 years ago.

Researchers in Australia found evidence for the early onset of warming after trawling through 500 years of data on tree rings, corals and ice cores that together form a natural archive of Earth’s historical temperatures.
