How warming affects crop yields worldwide

A new study shows that rising temperatures are cutting into the global yields of crops such as wheat and corn. Overall, however, the impact of global warming has been less than expected, as some countries also reported increases in crop yields because of higher levels of carbon dioxide, which can act like a fertilizer to encourage plant growth. However, the authors of the study caution that warming is expected to speed up in coming years, increasing pressures on the global food production system.

  • Annan: African leaders are wasting economic growth
    The rapid economic growth across Africa is at risk of being squandered by leaders who are more intent on clinging to power than promoting the health and welfare of their people, Kofi Annan, former UN secretary-general, said at a World Economic Forum meeting in South Africa. Growth across the continent is averaging 5.5%, he said, but too little is being done to create jobs for young people, or invest in manufacturing and infrastructure.

    The Bahrain regime is being pressured by Navi Pillay, the UN high commissioner for human rights, to release political activists detained since its bloody crackdown on anti-government protests.

  • Gadhafi regime assets to help fund Libyan rebels
    The administration of U.S. President Barack Obama is working with the U.S. Congress to pass a new law that would free up some $30 billion in frozen assets of the Libyan regime of Moammar Gadhafi, a portion of which would be steered to the country's rebel movement. Talks in Rome among the Libyan international contact group yielded a temporary fund through which funds could be delivered for food, medicine, military salaries and other basic supplies -- but, ostensibly, not for weapons.
