Tampa Bay coastal acidification research featured in EPA National Estuary Program report

Tampa Bay coastal acidification research conducted by Dr. Kim Yates of SPCMSC was highlighted in the latest Environmental Protection Agency (EPA) National Estuary Program (NEP) Report, “The National Estuary Program: At the Forefront of Climate Change Adaptation, Hazard Mitigation, and Resilience.”

Dr. Kim Yates of the USGS St. Petersburg Coastal and Marine Science Center has partnered with the Tampa Bay Estuary Program, EPA National Estuary Program, University of South Florida, and other state and local collaborators for several years to conduct coastal acidification research in Tampa Bay. The partners developed and deployed two ocean carbon systems, one within the bay and a second 60 miles offshore in the Gulf of Mexico to study changes in acidification parameters within and near the bay. The results of these studies are used to study processes and consequences of acidification, effects of seagrass beds on seawater carbon chemistry and blue carbon, and the potential role of seagrass in protecting Tampa Bay’s marine species from harmful effects of climate change and coastal and ocean acidification. These data are shared and compared across regions and synthesized into national assessments such as the recent EPA report, “Measuring Coastal Acidification Using in Situ Sensors in the National Estuary Program.”

New report shows impacts of climate change and extreme weather in Latin America and Caribbean (text & video)

LAC State of the Climate 2020

Climate change and extreme weather are threatening human health and safety, food, water and energy security and the environment in Latin America and the Caribbean. The impacts span the entire region, including Andean peaks, mighty river basins and low-lying islands, according to a new report from the World Meteorological Organization (WMO). It flags concerns about fires and the loss of forests which are a vital carbon sink.

The “State of the Climate in Latin America and the Caribbean 2020” provides a snapshot of the effects of increasing temperatures, changing precipitation patterns, storms and retreating glaciers. It includes transboundary analyses, such as of the drought of the South American Pantanal and the intense hurricane season in Central America-Caribbean. It provides a detailed regional breakdown of worsening global climate change indicators.

The report and an accompanying story map show how marine life, coastal ecosystems and the human communities that depend on them, particularly in Small Island Developing States, are facing increasing threats from ocean acidification and heat and rising sea levels.

The report was released at a high-level conference on 17 August, “Working together for weather, climate and water resilience in Latin America and the Caribbean” under the auspices of WMO, the UN Economic Commission for Latin America and the Caribbean (UNECLAC), and the UN Office for Disaster Risk Reduction (UNDRR).

It follows the release of the Intergovernmental Panel on Climate Change report on Climate Change 2021: the Physical Science basis, which said that temperatures in the region have increased more than the global average and are likely to continue to do so. It also projected changing precipitation patterns, more sea level rise, coastal flooding and marine heatwaves.

Global warming ‘unequivocally’ human driven, at unprecedented rate: IPCC

Climate change is widespread, rapid, and intensifying, and some trends are now irreversible, at least during the present time frame, according to the latest much-anticipated Intergovernmental Panel on Climate Change (IPCC) report, released on Monday.

Human-induced climate change is already affecting many weather and climate extremes in every region across the globe. Scientists are also observing changes across the whole of Earth’s climate system; in the atmosphere, in the oceans, ice floes, and on land.

Many of these changes are unprecedented, and some of the shifts are in motion now, while some – such as continued sea level rise – are already ‘irreversible’ for centuries to millennia, aheadthe report warns.

But there is still time to limit climate change, IPCC experts say. Strong and sustained reductions in emissions of carbon dioxide (CO2) and other greenhouse gases, could quickly make air quality better, and in 20 to 30 years global temperatures could stabilize.

‘Code red for humanity’

The UN Secretary-General António Guterres said the Working Group’s report was nothing less than “a code red for humanity. The alarm bells are deafening, and the evidence is irrefutable”.

He noted that the internationally-agreed threshold of 1.5 degrees above pre-industrial levels of global heating was “perilously close. We are at imminent risk of hitting 1.5 degrees in the near term. The only way to prevent exceeding this threshold, is by urgently stepping up our efforts, and persuing the most ambitious path.

“We must act decisively now, to keep 1.5 alive.”

The UN chief in a detailed reaction to the report, said that solutions were clear. “Inclusive and green economies, prosperity, cleaner air and better health are possible for all, if we respond to this crisis with solidarity and courage”, he said.

He added that ahead of the crucial COP26 climate conference in Glasgow in November, all nations – especiall the advanced G20 economies – needed to join the net zero emissions coaltion, and reinforce their promises on slowing down and reversing global heating, “with credible, concrete, and enhanced Nationally Determined Contributions (NDCs)” that lay out detailed steps.

Key climate change effects on the coastal and marine environment around the Pacific UK Overseas Territories

• Climate-driven changes in the central south Pacific Ocean will cause widespread warming of ocean waters, altered circulation, increased stratification of the water column and limited nutrient supply to the surface, decreasing dissolved oxygen, ocean acidification and rising sea levels. These changes will impact marine and terrestrial ecosystems and the communities they support.

• Ultimately, important sectors, such as fisheries and tourism, will be affected by these changes, as will food and water security and essential services, such as energy, transport of goods and coastal protection.

• Coral reefs are unlikely to experience significant heat stress, but should they be impacted by changes in sea temperature, including cold water intrusion, their recovery appears challenging due to the islands’ isolation and therefore the low supply of healthy coral larvae from other reef systems. By the end of the century, even under lowemissions scenarios, acidification conditions in the seawater around the Pitcairn Islands are likely to become marginal for coral calcification.

• Increasing Sea Surface Temperature (SST), ocean acidification and related changes to oxygen concentrations and stratification are expected to affect the health of coral reefs that support coastal fisheries in the Pitcairn Islands, and reduce productivity. Pelagic tuna fisheries are also expected to be affected by climate change with a slight increase in biomass for all tuna species projected for this part of the central south Pacific Ocean.

• Rising sea levels, storm surges, severe storm events and heavy rains will impact infrastructure networks on Pitcairn Island and the safe transport of goods via shipping to the island. Integrating climate change considerations into existing and new infrastructure is essential for building resilience to future climate change impacts.

• Downscaled projections for the Pitcairn Islands (at a relevant scale) will be particularly important for SST, since it is postulated that coral reefs and marine species may be buffered from regional increasing SST due to circulation patterns. This dynamic needs to be examined further to determine if it is in fact occurring or likely to occur, and therefore improve understanding on the potential impacts of increasing SST on marine ecosystems.

State of the global climate 2020

In order to unpack such complexity, the WMO State of the Global Climate uses seven Climate Indicators to describe the changing climate providing a broad view of the climate at a global scale. They are used to monitor the domains most relevant to climate change, including the composition of the atmosphere, the energy changes that arise from the accumulation of greenhouse gases and other factors, as well as the responses of land, oceans and ice. The following site aims to provide an overview of the annually produced State of the Climate report.

New report highlights why the ocean matters in climate negotiations & suggests positive actions nations can take as the countdown to COP26 is underway

Leading UK experts shine a spotlight on the critical role the ocean plays in greatly slowing the rate of climate change but also the subsequent impacts of this and why support from nations for better inclusion of the ocean at the United Nations climate negotiations, such as COP26 in Glasgow this November, is so important.

The briefing, led by Plymouth Marine Laboratory, summarises the latest research and knowledge on the importance of the ocean, as well as offering a range of opportunities to nations in order to ensure that the ocean can be developed sustainably for the benefits it provides to people around the world.

Developed by a team of experts from leading UK marine and environmental science universities and centres and published in association with the COP26 Universities Network, the briefing also makes suggestions on how the ocean can be better incorporated in the United Nations Framework Convention on Climate Change (UNFCCC) process.

The key messages are:
