Delegates to the U.N. climate change conference in Bonn June 6-17 are expected to focus on relatively low-profile issues even though the gathering is likely to be the last round of large-scale negotiations before the U.N. summit in Durban, South Africa, in late November. Expected topics include national pledges for technology transfer; assessments of vulnerability and adaptation issues; public awareness issues; commitments to international cooperation; the need to establish political clarity on the future of the Kyoto Protocol; and greater agreement on the need to establish a second compliance period under the protocol.
