What Are Some Solutions To Climate Change – Increasing renewable energy, greening the shipping industry and eating more seaweed are among ocean-based solutions that could help meet global goals to reduce greenhouse gas emissions, according to a landmark report. In the first analysis of its kind, scientists and policymakers have found that the ocean may play a much larger role in climate mitigation than previously thought.
It has the potential to deliver more than one-fifth (21%) of the emissions reductions needed by 2050 to keep global average temperature increases to the Paris Agreement target of 1.5C – the equivalent of shutting down all the world’s coal-fired power. Power generation plant.
What Are Some Solutions To Climate Change
It shows that the ocean is much more than a victim of climate change. It is also a powerful source of solutions. “Given political will, appropriate policies and investment in technology, the ocean can become a new ally in the war,” the authors wrote in the report titled “The ocean as a solution to climate change: five opportunities for action.”
What Is Climate Change?
“Our future health and prosperity are closely linked to the state of the oceans,” said panel co-chair and Norwegian Prime Minister Erna Solberg. “This report signals an exciting new path to a low-carbon, climate-resilient future. Combined with land-based emissions reductions, it shows that ocean-climate action is a frontline for climate disruption for economies, food sources, coastal communities and marine life. can provide a lifeline.”
It was published in New York on Monday at the UN Climate Action 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 climate change is having. 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 less productive. The effects of these changes are seen in intense coral bleaching, rising sea levels, rapid Arctic ice loss, extreme storms. Without action, the IPCC is expected to warn, these impacts will worsen, threatening the future of everyone – but especially the most vulnerable people living in small island states and densely populated coastlines.
“The ocean has not seriously been on the radar screen of the climate change policy community for a very long time,” said Jane Lubchenko, former NOAA (National Oceanic and Atmospheric Administration) administrator and co-chair of the expert group. Report “As a result of this report, it needs to be squarely on the radar screen. These options are going to give us some powerful new tools in our toolbox.”

The report, commissioned for the High Level Panel on a Sustainable Ocean Economy, a group of heads of government, explored five scenarios where a healthy ocean can help mitigate climate change, develop a sustainable ocean economy, protect coastal communities from storms, provide jobs . and improve food safety:
A fifth option explores carbon-based storage options such as injecting CO2 into the ocean floor to stimulate the growth of carbon-locking biomass or fertilizing the ocean with nutrients. But the potential for reducing emissions has not been factored in because of the uncertainty and risk surrounding such geoengineering methods.

“The first four opportunities are those for which we have sufficient data that there are good mitigation benefits but also strong co-benefits in other parts of the socio-ecological-economic nexus. These should be acted upon immediately,” said Ove Hoeg-Guldberg, lead coordinating author, director of the Global Change Institute and professor of ocean science at the University of Queensland in Australia. “[For Class V], additional research and consideration is needed before it is ready to be adopted at a scale that can make a difference from a climate perspective.”
Geoengineering Solutions For Climate Change Are Gaining Traction
Norway’s prime minister convened a high-level panel last year to find effective solutions on ocean health. With 14 heads of government from Australia, Canada, Chile, Fiji, Ghana, Indonesia, Jamaica, Japan, Kenya, Mexico, Namibia, Norway, Palau and Portugal, it represents about 30% of the world’s coastline, 30% exclusive economic zone, 20% Ocean catch and 20% of the global shipping fleet.
In addition to releasing its report, the leaders issued an urgent “call to action” on a number of ocean-based issues they say will meet both the Paris Agreement and the UN’s Sustainable Development Goals, including investing in nature-based solutions that already exist and ocean monitoring and Extension of research.
Nature-based solutions are a key part of the ongoing climate talks that are on the agenda in New York this week, as well as the upcoming Climate Conference (COP) in Santiago, Chile in December and the COP in Kunming, China next October on biodiversity. China and New Zealand are co-chairing the Nature-Based Solutions Initiative which will examine the feasibility of reforestation projects and the expansion of grasslands and wetlands to absorb greenhouse gases. On Friday, the IUCN released a report on nature-based solutions that noted that more than 70% of nationally determined contributions to emissions reductions refer to forest restoration or conservation, but only 20% of these include quantifiable targets and only 8% express targets. including Tons of carbon dioxide equivalent.
Ahead of a key UN ocean conference in Lisbon next June, several members of the panel also announced commitments to ocean action. Among them, Norway has pledged to halve its shipping emissions by 2030; Fiji has pledged to make its shipping sector 100% decarbonised by 2050; Kenya will include “blue carbon” ecosystems in its Nationally Determined Contribution; And Mexico will declare an additional 31 areas as fish sanctuaries.
Communicating Climate Change: Science, Solutions, Solidarity
The UN Secretary-General’s Special Envoy for Oceans, Peter Thomson, said: “The world already has the technology needed to accelerate ocean-based climate solutions. To stay true to the Paris Climate Agreement and hold warming to 1.5C, we will be ocean-based next year in their revised Nationally Determined Contributions. Calling for the inclusion of climate solutions.”

By now, the dire dangers of climate change are obvious to anyone paying attention, covered extensively in both the academic literature and the popular press.
Climate Change Documentaries And Series That Will Give You An Up Close Look — And Some Solutions |
For all the hand-wringing over climate change over the years, talk of solutions has remained surprisingly anemic and fractured. Some high-profile approaches, mainly around renewable energy and electric vehicles, dominate discussion and modeling. Until 2017, there was no real way for ordinary people to understand what they could do and what impact it could have. There was no single, comprehensive, reliable compilation of carbon-reduction solutions across sectors.
Hawken is a legend in environmental circles. Since the early 1980s, he has been starting green businesses, writing books on environmental commerce (President Bill Clinton called Hawkins’ Natural Capitalism one of the five most important books in the world), consulting with businesses and governments, speaking to civic groups and collecting. Honorary doctorates (six so far).
A few years ago, he began pulling together the careful coverage of solutions that had been lacking until now. With little funding, he and a team of dozens of research fellows “map, measure, and model” the 100 most important solutions to climate change, using only peer-reviewed research.
The results, published in April 2016, are called Drawdown: The Most Comprehensive Plan Ever Proposed to Reverse Global Warming.

Unlike most popular books on climate change, this is not a debate or a collection of anecdotes and advice. Indeed, apart from a few thoughtful essays scattered throughout, it is essentially a reference book: a list of solutions ranked by potential carbon impact, with cost estimates for each, and a brief description. A set of circumstances shows increasing probability.
