95% of existing ocean climates could disappear by 2100 if CO2 emissions continue to climb

95% of existing ocean climates could disappear by 2100 if CO2 emissions continue to climb

Canada is home to three oceans, all of which harbour thousands of fish and animals, on which many Canadians rely. But, with a warming planet, these bodies of water are rapidly changing.

A new study published in the journal Scientific Reports suggests that our oceans’ climates — existing environments with delicately balanced ecosystems — face extreme change under climate-change scenarios.

Climate change fueling warm ocean ‘blob’ causing Chile megadrought – study

By Cassandra Garrison

(Reuters) – A blob of warm water in the southern Pacific is fueling a decade-long megadrought in Chile, and climate change is at least partly to blame, scientists say.

Novel and disappearing climates in the global surface ocean from 1800 to 2100

Abstract

Marine ecosystems are experiencing unprecedented warming and acidification caused by anthropogenic carbon dioxide. For the global sea surface, we quantified the degree that present climates are disappearing and novel climates (without recent analogs) are emerging, spanning from 1800 through different emission scenarios to 2100. We quantified the sea surface environment based on model estimates of carbonate chemistry and temperature. Between 1800 and 2000, no gridpoints on the ocean surface were estimated to have experienced an extreme degree of global disappearance or novelty. In other words, the majority of environmental shifts since 1800 were not novel,

The amount of carbon dioxide in Earth’s atmosphere reached 419 parts per million in May, its highest level in more than four million years, the National Oceanic and Atmospheric Administration announced on Monday.

Innovation Outlook: Ocean Energy Technologies

Innovation Outlook: Ocean Energy Technologies

Oceans contain vast renewable energy potential – theoretically equivalent to more than double the world’s current electricity demand. Nascent ocean energy technologies could cut carbon dioxide (CO2) emissions from power generation and help to ensure a sustainable, climate-safe energy future.

Alongside other offshore renewable energy technologies, ocean energy – including wave, tidal, salinity gradient and ocean thermal energy conversion technologies – forms a crucial component in the world’s emerging blue economy.

This outlook from the International Renewable Energy Agency (IRENA)

Fostering a blue economy: Offshore renewable energy

Fostering a blue economy: Offshore renewable energy

Offshore renewable energy – including offshore wind and solar power, as well as emerging ocean energy technologies – could support sustainable long-term development and drive a vibrant blue economy. For countries and communities around the world, offshore renewables can provide reliable, stable electricity, as well as support water desalination and aquaculture. This report from the International Renewable Energy Agency (IRENA) considers the status and prospects of offshore renewable sources and recommends key actions to accelerate their uptake. The development of renewable sources and technologies at sea promises to spur new industries and create jobs in line with the global energy transition. Offshore wind towers, with either fixed or floating foundations, and floating solar photovoltaic (PV) arrays offer clear technological and logistical synergies with the existing offshore oil and gas industry. Offshore renewables could provide clean power and ensure energy security for small island developing states (SIDS) and many of the least-developed countries (LDCs). Among other findings: The predictability of power generation from ocean energy technologies complements the variable character solar PV and wind. Desalination of seawater using renewable energy sources – including solar and wind power, but also direct solar and geothermal heat – can further enhance the sustainable blue economy. Renewable-based shipping, powered with advanced biofuels, hydrogen or synthetic fuels as alternatives to oil, offer further synergies with offshore renewable energy. Islands and coastal territories could adopt renewable-based electric propulsion for short-distance (< 100 km) sea transport. Two reports, released concurrently, examine the potential for offshore renewables: Fostering a blue economy: Offshore renewable energy Innovation outlook: Ocean energy technologies See an overview their key findings. Key findings are also...
IRENA and Ocean Energy Europe Partner to Drive Ocean Energy Industry

IRENA and Ocean Energy Europe Partner to Drive Ocean Energy Industry

New IRENA reports forecast a 20-fold growth potential of ocean energy by 2030, providing coastal communities with a climate-safe roadmap for COVID-19 recovery The CEO of Ocean Energy Europe (OEE), Rémi Gruet and the Director-General of the International Renewable Energy Agency (IRENA), Francesco La Camera, signed a Memorandum of Understanding (MoU) today at the annual Ocean Energy Europe Conference & Exhibition. The partnership will deepen existing cooperation to accelerate the commercialisation of ocean energy technologies, by promoting the right policy incentives and innovative business models in Europe and globally. Oceans hold abundant, largely untapped renewable energy potential that could drive a vigorous global blue economy, as two new studies, also released today by IRENA show. Fostering a blue economy: Offshore renewable energy and the Agency’s Innovation outlook: Ocean energy technologies find that in addition to providing mainstream power generation, a blue economy driven by offshore renewables will bring major benefits to Small Island Developing States (SIDS) and coastal communities. Ocean energy can not only help to decarbonise power generation, provide affordable and reliable access to electricity, help countries to fulfil Paris Agreement pledges and contribute to global climate action. Offshore renewables can help meet energy needs for shipping, cooling and water desalination, laying the foundation for a broad-based blue economy and industry. They create jobs, improve health, strengthen people’s livelihoods and foster wider socioeconomic opportunities for a green recovery from COVID-19. Francesco La Camera, Director-General of IRENA said: “Renewable energy from oceans has the potential to meet four times the global electricity demand of today, foster a blue economy, and bring socio-economic benefits to some of the most vulnerable areas to climate change such as SIDS...
