Three-quarters of the 184 countries that signed the Paris Climate Agreement have climate plans that experts deem “totally insufficient” to keep the planet well below 3.6 degrees Fahrenheit (2 degrees Celsius) of warming, according to the authoritativenew analysis. The Paris signatories a...
Many countries have recently announced the ambition to reach net-zero emissions targets. Here we explore the climate and energy transition impacts of the following strategies using the IMAGE integrated assessment model: 1) implementing the pledged 2030 targets and net-zero targets, 2) aligning the ...
The temperature targets in the Paris Agreement cannot be met without very rapid reduction of greenhouse gas emissions and removal of carbon dioxide from the atmosphere. The latter requires large, perhaps prohibitively large subsidies. The central estimate of the costs of climate policy, unrealistically...

The good news: the Paris climate agreement is likely tocome into effect this year, earlier than expected. But even if countries stick to their Paris targets itwill not be nearly enough to limit warming to 2 °C. And the bad news is that the second biggest polluter, the US, is...
“Currently, an estimated 18 million people work in the energy industries — a number that is likely to increase, not decrease, to 26 million or by over 50% if we reach our global climate targets,” says corresponding author Johannes Emmerling, an environmental economist...
(EV) market and meet its international climate commitments. Setting ambitious EV sales targets and transitioning to zero-carbon power sources in the United States and other nations could lead to significant reductions in carbon dioxide and other greenhouse gas emissions in the transportation sector and...
in full as soon as possible and by 2050 at the latest. The IMO plan is a first step in the right direction, but much more needs to be done to achieve climate stability. The initial deal will be revised in 2023 and reviewed again in 2028, giving opportunities to strengthen the targets....
Less than a year after its inception, the Paris climate change agreement is officially in force—but the United Nations has warned that governments must dramatically reduce carbon emissions to meet its goals. The agreement, drawn up last December, was formally ratified by enough nation-states l...
without biophysical feedbacks (Methods). We force these patterns with prescribed global temperature time series that approach 1.5° and 2 °C warming targets by 2100 (Methods)28. The use of JULES-IMOGEN allows climate change impacts to be included in an assessment of the effectiveness of an...
