This overview sets the scene for the various modules in the Renewables 2024 Global Status Report Collection. It provides high-level trends on the status of renewables in the wider fossil fuel-dominated energy system in the context of global challenges such as climate change, development goals and the geopolitical landscape. Urgent …
Urbanisation is one of the most important drivers of productivity and growth in the global economy. Between 2014 and 2050, the urban population is projected to increase by around 2.5 billion people, reaching 66% of the global population. By 2030, China’s cities alone will be home to nearly 1 billion …
A HEATWAVE hovered over Brisbane, the state capital of Queensland, as world leaders gathered on November 15th for a Group of 20 (G20) summit, the biggest such meeting Australia has hosted. Tony Abbott, the prime minister, had hoped to limit their talks to topics that chimed with his domestic political …
Setting stringent targets for emission cuts for the world, a UN body wants countries across the globe to collectively cut carbon emission to zero (achieve carbon neutrality) by 2070 and bring down emissions to net zero for all greenhouse gases, including methane, nitrous oxide and climate damaging refrigerant HFC, by …
The world must cut CO2 emissions to zero by 2070 at the latest to keep global warming below dangerous levels and prevent a global catastrophe, the U.N. warns. By 2100, all greenhouse gas emissions — including methane, nitrous oxide and ozone, as well as CO2 — must fall to zero, …
As carbon dioxide continues to enter out Earth's atmosphere, the ocean is continuing to acidify. Now, scientists have developed a new way to measure how this acidification is affecting marine ecosystems over an entire oceanic basin. When CO2 enters our atmosphere, it also mixes with seawater. This accumulation of CO2 …
Negative emissions’ are needed globally by second half of century to stave off dangerous climate change, say UN scientists The world must cut CO2 emissions to zero by 2070 at the latest to keep global warming below dangerous levels and prevent a global catastrophe, the UN warns. By 2100, all …
Brazil's annual greenhouse gas emissions increased last year for the first time since 2004 after years of reductions as deforestation and the use of thermal power plants rose, a new study found. Latin America's largest economy generated 1.56 billion tonnes of carbon dioxide equivalent (CO2e) in 2013, a 7.8 percent …
A majority of Americans support tougher pollution limits on coal-burning power plants even if it means paying more for electricity. The survey of 1,275 adults backs President Barack Obama’s efforts to bypass Congress and enact climate regulations by executive authority. Two thirds of those polled by researchers at Yale and …
Boosts in crop productivity such as corn reportedly cause an upswing in the carbon dioxide cycle, according to a new study, meaning plants are pulling in more atmospheric carbon as well as releasing more. Deluge, droughts, rising sea levels, and shrinking water tables - these are the things of nightmare …
China is ramping up efforts to curb domestic carbon emissions and to bridge differences in global negotiations, a welcome sign from a "constructive leader" in climate change, the United Nations' top climate official said on Tuesday. "Controlling greenhouse gas emissions for the world largest emitter is the equivalent of reducing …
Officials in San Francisco and Berkeley are considering what they say would be a first-in-the-nation move to require warnings about climate change to be placed at gas pumps at filling stations in the two California cities. In famously liberal Berkeley, the City Council voted on Tuesday to draft an ordinance …
Rich countries are meeting in Berlin on Thursday to pledge cash to smooth the way for a global climate change deal. The Green Climate Fund is designed to help poor nations adapt to climate extremes like droughts and floods and to buy low-carbon energy sources. Rich nations previously vowed that …
The atmospheric carbon dioxide (CO2) record displays a prominent seasonal cycle that arises mainly from changes in vegetation growth and the corresponding CO2 uptake during the boreal spring and summer growing seasons and CO2 release during the autumn and winter seasons. The CO2 seasonal amplitude has increased over the past …
Ground- and aircraft-based measurements show that the seasonal amplitude of Northern Hemisphere atmospheric carbon dioxide (CO2) concentrations has increased by as much as 50 per cent over the past 50 years. This increase has been linked to changes in temperate, boreal and arctic ecosystem properties and processes such as enhanced …
The International Energy Agency (IEA) laid out five actions needed over the short- and long-term to achieve a low-carbon energy sector, and proposed concrete options for their implementation in the international climate negotiations to be held next month in Lima, Peru. Energy accounts for two-thirds of global greenhouse gas emissions, …
China, a week after unveiling an accord aimed at limiting carbon emissions, plans to cap the increasing rate at which it consumes energy to 28 percent for the seven-year period to 2020. The nation is targeting energy use equivalent to an annual 4.8 billion metric tons of standard coal by …
The analysis calculates an emissions gap relative to expected emission levels in 2030, in recognition of the growing focus that action beyond 2020 is gaining in international climate change negotiations. Not least, the report provides an assessment of the carbon budget that is consistent with the 2° Celsius temperature target.
Brazil, Latin America’s largest source of carbon emissions, is maintaining its position that developed nations should be held responsible for their historic contributions to climate change, according to Carlos Klink, Brazil’s climate change secretary. The question has become more pressing since the Nov. 12 climate agreement between the world’s biggest …
The United Nations Food and Agriculture Organization (FAO) has today published a comprehensive pocketbook of nutrition-related data covering all regions of the world ahead of the Second International Conference on Nutrition (ICN2) taking place in Rome this week. Food and Nutrition in Numbers- a pocket-seized compendium dedicated to the state …
