Limiting global warming to 1.5ºC would require rapid, far-reaching and unprecedented changes in all aspects of society, the Intergovernmental Panel on Climate Change (IPCC) said in a new assessment. With clear benefits to people and natural ecosystems, limiting global warming to 1.5ºC compared to 2ºC could go hand in hand with ensuring a more sustainable and equitable society.
The WMO Greenhouse Gas Bulletin reports on atmospheric concentrations of greenhouse gases in the earth’s atmosphere. The report found that levels of heat-trapping greenhouse gases in the atmosphere have reached another new record high, according to the World Meteorological Organization. There is no sign of a reversal in this trend, which is driving long-term climate change, sea level rise, ocean acidification and more extreme weather.
The flagship report from UN Environment is the definitive assessment of the ’emissions gap’ – the gap between anticipated emission levels in 2030, compared to levels consistent with a 2°C / 1.5°C target. It found that global emissions are on the rise as national commitments to combat climate change come up short. But surging momentum from the private sector and untapped potential from innovation and green-financing offer pathways to bridge the emissions gap.
The next 2-3 years are a critical window when many of the policy and investment decisions that shape the next 10-15 years will be taken. The New Climate Economy report found that leaders are already seizing the exciting economic and market opportunities of the new growth approach, while the laggards are not only missing out on these opportunities but are also putting us all at greater risk. More than US$26 trillion and a more sustainable planet are on offer, if everyone gets on board.
