It is emphasized in the passage that ----.
Scientists have urged national leaders for years to
tackle climate change, based on the assumption that all
nations should take steps in harmony for the success of
their prevention efforts. But as anyone who has watched
the past 15 years of international climate negotiations
can attest, most countries are still reluctant to take
meaningful steps to lower their production of
greenhouse gases, much less address issues such as
how to help developing countries protect themselves
from the extreme effects of climate change. Mayors and
urban managers are taking over as they have a keener
sense about how changing weather patterns will affect
their cities’ political and economic futures. Indeed, within
months after Hurricane Katrina’s landfall, the C40 Cities
Climate Leadership Group launched in London in
October 2005, and the World Mayors Council on
Climate Change (WMCCC) got its start in Kyoto that
December. As of June 2011, more than 190 mayors and
other local authorities, representing some 300 million
people from around the world, have also signed a
voluntary pact sponsored by the WMCCC to reduce
greenhouse gas emissions. They are tackling climate
change, as their cities are suffering from floods, rising
sea levels and heat waves. They are innovating ways to
reduce carbon dioxide emissions, prevent further
changes in weather patterns and benefit from
transportation systems that protect the environment.
