With the current emission reduction targets set us on a pathway to 2.7-3.1 degrees Celsius, the report illustrates the urgent need for country leaders to step up their efforts to reach the targets set in the Paris climate agreement

MANILA, Philippines (Dec. 3, 2017) — The climate battle is an uphill trek. With our current commitments to reduce our carbon emissions, we are not on track to achieve the principal aim of the Paris climate agreement: keeping global temperature rise to well below 2 degrees Celsius, while pursuing 1.5 degrees Celsius.

Ocean Circulation, Carbon Cycling During the Last Deglaciation

Last summer, scientists met to discuss changes in ocean circulation between this glacial maximum period and the present time and how these changes are related to changes in the climate and carbon cycling.

Past Global Changes (PAGES) OC3 Working Group second workshop on Ocean Circulation and Carbon Cycling during Last Deglaciation: Regional Synthesis of Carbon Isotopes Data; Corvallis, Oregon, 27–29 June 2017

December 3, 2017 — Scientists still don’t fully understand the climatic transition that took place on Earth between the Last Glacial Maximum and recent times. Even though carbon cycling and the associated rise in atmospheric carbon dioxide (CO2) during this Continue reading Ocean Circulation, Carbon Cycling During the Last Deglaciation

Why climate change is one of the biggest health threats of the 21st century

HEALTH. Studies show that climate change can undo more than 50 years of gains in global health and development work.

The roles and responsibilities of health professionals go way beyond treating diseases

MANILA, Philippines (Nov. 23, 2017) — What makes climate change one of the biggest health threats of the 21st century? Continue reading Why climate change is one of the biggest health threats of the 21st century

Scientists measure dissolved black carbon in South China Sea water samples to better understand the carbon cycle in the oceans, which absorb roughly half of all carbon emitted into the atmosphere

November 21, 2017 — To fully understand how the oceans regulate carbon concentrations in the atmosphere, scientists must have detailed knowledge of the marine carbon cycle. A large amount of Continue reading Plumbing the Depths of the Marine Carbon Cycle

US mayors and governors want to show the world they stand by US commitments, but to their African counterparts solidarity means cash

November 13, 2017 — The presence of US cities and states at UN climate talks in Bonn has been big, brash and supercharged with billionaire cash. Continue reading For Africans, America’s pledge is about more than pollution

Fossil fuel burning set to hit record high in 2017, scientists warn

The rise would end three years of flat carbon emissions – a ‘huge leap backward’ say some scientists, while others say the longer term trend is more hopeful

November 13, 2017 — The burning of fossil fuels around the world is set to hit a record high in 2017, climate scientists have warned, following three years of flat growth that raised hopes that a peak in global emissions had been reached. Continue reading Fossil fuel burning set to hit record high in 2017, scientists warn

COP23: Plea for ‘urgent action’ on climate shadowed by Trump

The concern is more whether other leaders who were already reluctant to foreswear fossil fuels as the main engine of economic growth for their countries will lose resolve

BONN, Germany (Nov. 7, 2017) — Following a cascade of grim reports on the gathering pace of global warming, Fiji’s prime minister on Monday, November 6, appealed for “urgent action” on climate change at UN negotiations in Bonn.

India’s population and emissions are rising fast, and its ability to tackle poverty without massive fossil fuel use will decide the fate of the planet

November 6, 2017 — “It’s a lucky charm,” says Rajesh, pointing to the solar-powered battery in his window that he has smeared with turmeric as a blessing. “It has changed our life.” Continue reading How India’s battle with climate change could determine all of our fates

To avoid dangerous levels of global warming, the international community has pledged to limit global temperature rise to less than 2°C above pre-industrial levels

November 2, 2017 — This commitment requires rapid and sustained reductions in greenhouse gas (GHG) emissions over the next few decades from all of the world’s major emitters. To meet this Continue reading Analysis: WRI data suggests emissions have already ‘peaked’ in 49 countries

IPCC Chair Discusses Limiting Global Warming to 1.5°C

Several forthcoming reports by the Intergovernmental Panel on Climate Change examine what needs to be done to take control of our climate future

November 1, 2017 — With a United Nations climate change conference scheduled for Bonn, Germany, from 6 to 17 November, two high-level reports released this week warn about the increasing risk of climate change. In addition, the Intergovernmental Panel on Climate Change (IPCC) is working on a separate report, to be issued in 2018, about the effects of global warming at 1.5°C above preindustrial levels.
