Possible Solutions To Global Warming – We are already seeing the devastating effects of global warming with rising sea levels, massive storms, prolonged droughts and increasing wildfires. Now, after two years of research and modeling, scientists have created an innovative new framework to meet – and even exceed – the goal of limiting warming to 1.5°C.
Research by leading scientists from the University of Technology Sydney (UTS), the German Aerospace Center and the University of Melbourne has been funded by the Leonardo DiCaprio Foundation (LDF) as part of its new One Earth initiative.
Possible Solutions To Global Warming
LDF founder Leonardo DiCaprio welcomes the framework, saying: “With an increase in urgent climate warnings, it is clear that our planet cannot wait for meaningful action. This ambitious and necessary journey shows that the transition to 100% renewable energy and strong measures to protect and restore our natural ecosystems can ensure a more sustainable climate within one generation.”
Fast Tracking Solutions To Climate Change
A special report by the Intergovernmental Panel on Climate Change (IPCC) last October warned that the planet must be kept under a dangerous temperature increase of 1.5°C compared to pre-industrial levels if we are to ‘ avoid more severe climate effects. found now. observed at 1°C. The 2016 Paris Agreement on climate change set a goal to keep warming below 1.5°C.
This new research has produced the most detailed energy model to date – and the first to capture negative emissions through natural climate solutions. Her proposal to transition to 100% renewable energy by mid-century, along with measures such as reforestation, would not only bring climate benefits but also create millions of permanent jobs. Scientists say this could be done for about a quarter of the cost of current fossil fuel subsidies.
The research will model 72 regional power grids in hourly increments to 2050 and include a comprehensive assessment of available renewables such as wind and solar, along with arrangements to effectively meet to projected energy demand and storage for each sector over the next 30 years.
“Scientists cannot fully predict the future, but advanced modeling allows us to develop the best conditions for creating a global energy system fit for the 21st century,” said lead author Dr. Sven Teske, director of research at the UTS Institute for Sustainable Futures. “As momentum around the Paris Agreement lags behind, it is important that policy makers around the world see that we can meet energy demand world at a lower cost with clean renewables.”
Global Warming Problem And Solutions
The inquiry will go to the World Economic Forum in Davos this week. Dr Teske discussed the work at a recent meeting of COP24, the 24th Conference of the Parties to the United Nations Framework Convention on Climate Change.
While climate scientists have created hundreds of models to help policymakers understand the effects of climate change and how to mitigate them, almost all of these models have been rely on technologies that are expensive and have not been proven to work at scale when trying to reach more. only one limit. about emissions, but about “negative” emissions, where the carbon in the atmosphere is reduced.
This model is the first to achieve desired negative emissions through natural climate solutions, including the restoration of degraded forests and other land, along with a shift to renewable energy. 100% modern by mid century.
“Drawing on a growing body of research, we show that using land reclamation efforts to meet negative emissions requirements, combined with a shift to 100% renewable energy by 2050 , giving the world a good chance of staying below the 1.5 °C target.” Malte Meinshausen, founding director of the College of Climate and Energy at the University of Melbourne and a member of the Potsdam Institute, says.

Switching to 100% renewable energy sources and implementing natural climate solutions provide additional benefits beyond monitoring the climate system, the researchers say. The energy transition will recycle our natural gas infrastructure and create millions of permanent jobs. Natural climate solutions could greatly enhance sustainable livelihoods in the developing world by providing better water security and less soil erosion.
“Nature is the best solution to the climate crisis,” says Leonardo DiCaprio Foundation Executive Director Justin Winters. “Our wild lands and oceans currently contain half of the CO2 emissions. While a shift to renewable energy sources is necessary to solve the climate crisis, it is not sufficient. As this climate model shows, to maintain global temperatures rising to zero. above 1.5°C, we need to keep our natural carbon pools intact, increase restoration efforts and move to renewable agriculture.”
The proposed energy transition outlined in the climate model is estimated to cost about $1.7 trillion annually. That may sound like a lot, says Dr Teske, but it pales in comparison to the huge subsidies governments provide to support polluting fossil fuels, which are largely dependent on change. climate These are estimated to be more than $5 trillion a year or $10 million a minute every day, according to the IMF. For a third of that cost, we could create the clean energy future we so desperately strive for.
The climate model will be published in Achieving Paris Climate Agreement Goals: Global and Regional 100% Renewable Energy Scenarios with Non-Energy GHG Pathways for +1.5°C and +2°C early this year. The book will be published by Springer Nature as an open access title.

What Is Climate Change ?
This shows that there is much more to the ocean than just suffering from climate change. It is also a powerful source of solutions. “With political will, appropriate policy and investment in technology, the ocean could become a new ally in the fight,” the authors write in the report titled “The Ocean as a solution to climate change : five possibilities of action.”
“Our future health and prosperity is closely linked to the state of the ocean,” said Erna Solberg, co-chair of the panel and Prime Minister of Norway. “This report points to an exciting new path towards a low-carbon and climate-resilient future. Along with reducing emissions from land, it shows that ocean climate action could provide a lifeline to economies, food supplies, communities coastal and marine life on the front lines of climate disruption.
It was launched in New York on Monday at the UN climate change summit, two days ahead of the UN Panel on Climate Change’s (IPCC) Special Report on the Ocean and Cryosphere, which is expected to highlight the devastating effects of climate change on the ocean. and human well-being…
Excess greenhouse gases in the atmosphere have made the world’s oceans warmer, more acidic, less able to hold oxygen and more productive. The effects of these changes are shown by severe coral bleaching, rising sea levels, rapid loss of Arctic ice and extreme storms. Without action, the IPCC is expected to warn that these impacts will worsen and threaten the future of everyone – but especially the most vulnerable people living in small island states and on densely populated coasts.
