Solutions To Climate Change And Global Warming – Increasing renewable energy, greening the shipping industry and eating more seaweed are among ocean-based solutions that could help meet global targets to reduce greenhouse gas emissions, according to a landmark report. In the first analysis of its kind, scientists and policymakers have found that the oceans may play a larger role in climate mitigation than previously thought.

It has the potential to deliver more than a fifth (21%) of the emissions reductions needed by 2050 to keep global average temperature rises to the Paris Agreement target of 1.5C – the equivalent of shutting down all the world’s coal burning . power plant.

This shows that the ocean is more than a victim of climate change. It is also a powerful source of solutions. “Given political will, appropriate policy and investment in technology, the ocean can become a new ally in the fight,” write the authors in the report titled “The ocean as a solution to climate change: Five opportunities for action”.

How Much Would It Cost To End Climate Change? Get The Facts

“Our future health and prosperity are closely linked to the state of the oceans,” said Erna Solberg, co-chair of the panel and Norway’s prime minister. “This report points to an exciting new path towards a low-carbon and climate-resilient future. Together with land-based emissions reductions, this shows that ocean climate action can provide a lifeline for economies, food sources, coastal communities and marine life on the front lines of climate disruption.”

It was released in New York on Monday at the UN Climate Action Summit, two days ahead of the UN Climate Panel’s (IPCC) special report on the oceans and cryosphere, which is expected to highlight the devastating effects of climate change on the oceans. 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 severe coral bleaching, sea level rise, 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 along densely populated coasts.

“For too long, the ocean has not been seriously on the radar screen of the climate change policy community,” said Jane Lubchenco, former NOAA (National Oceanic and Atmospheric Administration) administrator and co-chair of the expert group that advised on the report. “The results of this report, it should be right on the radar screen. This option will give us some powerful new tools in the toolbox.”

Solutions For Climate Change

The report, commissioned by the High-Level Panel on a Sustainable Ocean Economy, a group of government leaders, examines five scenarios in which healthy oceans can help mitigate climate change, develop a sustainable ocean economy, protect coastal communities from storms, provide jobs and improve food security. :

A fifth option explores carbon-based storage options such as injecting CO2 into the seabed or fertilizing the ocean with nutrients to stimulate the growth of carbon-locking biomass. But such geoengineering methods are not considered in the emission reduction potential because of the uncertainties and risks that surround them.

“The first four opportunities are opportunities for which we have sufficient information that there are good mitigation benefits, but also strong co-benefits for other parts of the social-environment-economic nexus. This requires immediate action,” said lead coordinating author Ove Hoegh-Guldberg, director of the Global Change Institute, and professor of marine science at the University of Queensland, Australia. “[For] the fifth category, additional research and consideration is needed before it is ready for adoption. on a scale that will make a difference from a climate point of view.”

Unleashing Agi’s Potential: Catalyzing Solutions For Climate Change And Global Warming

A high-level panel was set up by the Norwegian prime minister last year to find workable solutions on ocean health. With 14 serving heads of government from Australia, Canada, Chile, Fiji, Ghana, Indonesia, Jamaica, Japan, Kenya, Mexico, Namibia, Norway, Palau and Portugal, it represents approximately 30% of the world’s coastline, 30% of the exclusive economic zone, 20% of the marine catch and 20% of the global shipping fleet.

In addition to releasing its report, the leaders also issued an urgent “call to action” on a number of ocean-based issues they say will meet the Paris Agreement and the UN’s Sustainable Development Goals, including investing in nature-based solutions that already exist and the expansion of ocean observation and research.

Nature-based solutions are an important part of the ongoing climate negotiations that will be on the agenda this week in New York, as well as at the upcoming Climate Conference of the Parties (COP) in Santiago, Chile, in December, and the biodiversity COP in Kunming, China, next October. China and New Zealand are co-chairing a nature-based solutions workstream that will explore the potential of reforestation schemes and the expansion of grasslands and wetlands to absorb greenhouse gases. On Friday, the IUCN published a report on nature-based solutions which showed that more than 70% of nationally determined contributions to reducing emissions refer to the restoration or conservation of forests, but only 20% of these include measurable targets, and only 8 % includes stated target. . in tonnes of carbon dioxide equivalent.

Ahead of the UN ocean summit in Lisbon next June, some of the panelists also announced pledges about ocean action. Among them, Norway has committed to halve its shipping emissions by 2030; Fiji has pledged to make its shipping sector 100% carbon-free by 2050; Kenya will incorporate the “blue carbon” ecosystem into its nationally determined contribution; and Mexico will declare an additional 31 areas as fish reserves.

Solutions For A World On Boil

The UN Secretary-General’s Special Envoy for Oceans, Peter Thomson, said: “The world already has the technology needed to mobilize ocean-based climate solutions. To stay committed to the Paris climate agreement and keep warming to 1.5C, we call on all states to include ocean-based climate solutions in their nationally determined contributions next year.”

Although changes to the Earth’s climate are nothing new, the recent effects appear to be having a negative impact on many people, places and wildlife. If you want to know what climate change really is and why it matters, read on to learn more about its causes, effects and practical solutions to stop it.

You may have heard the terms climate change and global warming used interchangeably. This is because both describe changes in the Earth’s climate. While global warming focuses on raising the planet’s average temperature, climate change generally refers to changes in things like rainfall, wind patterns, and temperatures over a period of time. Measured climate change can last for years, decades or even millions of years.

Climate change has been happening for as long as the earth has existed. This occurs when Earth’s climate patterns change and remain in place for a measurable period of time. This is evident in the natural cycle of cooling and heating. Before human causes begin to change the global climate, five main factors interact as climate change occurs. These five factors include: [1]

The American Association for the Advancement of Science stated: “The scientific evidence is clear: global climate change caused by human activity is occurring now, and it is an increasing threat to society.” [2]

What Is Climate Change? Causes, Consequences And Solutions

Greenhouse gases play an important role in the Earth’s climate cycle. When the planet hits the sun’s rays, some of the energy is absorbed, and the rest of the energy and heat is reflected back into space. Greenhouse gases in the atmosphere capture the reflected energy, redirect it back to the earth and ultimately contribute to global warming. Various gases play this role, including:[3]

While some of these greenhouse gases, such as water vapor, are naturally occurring, others, such as CFCs, are synthetic. CO2 is released into the atmosphere from natural and man-made sources and is one of the main contributors to climate change. CO2 is increasing at an alarming rate and has the potential to remain in the Earth’s atmosphere for thousands of years unless absorbed by the oceans, soil, trees and other sources. [4] However, as CO2 production increased, the earth’s natural resources to absorb it also decreased. It has already happened
