• Atmospheric CO2 levels top 400 PPM

    Scientists at the Mauna Loa observatory in Hawaii have registered atmospheric carbon dioxide levels of 400ppm. It is the first time they've been this high in more than 2 million years. What does this mean for the fight against runaway climate change? Scientists and environmental leaders weigh in.

    More than 17 million people from all walks of life signed a global call-to-action in advance of the Copenhagen climate talks in 2009. The petition, organized under the TckTckTck campaign banner, was one of the largest of its kind and represented hundreds of organizations across a broad range of social and environmental causes. Though the UN climate talks have yet to deliver a fair, ambitious and binding treaty on carbon pollution, the climate movement goes stronger every day.

    The verdict is in -- record breaking weather extremes around the globe are increasing as a result of human-made carbon pollution. But there is good news. The latest research shows we can transition to clean, renewable energy sources while supporting healthy, sustainable economic development. There's only one climate. Let's work to reverse global warming and bring the climate back into balance, so generations to come have a safe planet to call home.

Cities at risk for more heat-related deaths due to climate change

New research has found that heat-related deaths in cities will increase as climate change continues to worsen a global pattern of heat waves and record-setting high temperatures. Urban areas are especially vulnerable to the impacts of heat waves because the concrete environment traps heat, making temperatures higher than in surrounding rural areas.
