Sea-level legacy: 20cm more rise by 2300 for each 5-year delay in peaking emissions

02/20/2018 – Peaking global CO2 emissions as soon as possible is crucial for limiting the risks of sea-level rise, even if global warming is limited to well below 2°C. A study now published in the journal Nature Communications analyzes for the first time the sea-level legacy until 2300 within the constraints of the Paris Agreement. Their central projections indicate global sea-level rise between 0.7m and 1.2m until 2300 with Paris put fully into practice. As emissions in the second half of this century are already outlined by the Paris goals, the variations in greenhouse-gas emissions before 2050 will be the major leverage for future sea levels. The researchers find that each five year delay in peaking global CO2 emissions will likely increase median sea-level rise estimates for 2300 by 20 centimeters.

Sea-level legacy: 20cm more rise by 2300 for each 5-year delay in peaking emissions

Every delay in peaking emissions by 5 years between 2020 and 2035 could mean additional 20 cm of sea-level rise (Mengel et al 2018)

Provinces improve response to climate change

HÀ NỘI — Lessons learned from the strategic mainstreaming of ecosystem-based adaptation (EbA) was a good foundation for Việt Nam to prepare for climate change, according to Dr. Nguyễn Thế Chinh from the Natural Resources and Environment Strategic Institute.

Dr Chinh was speaking on Tuesday at a workshop reviewing a project on the subject. It was held by the Institute for Strategy and Policy on Natural Resources and Environment in collaboration with the German Development Co-operation Agency. The event marked more than three years of productive collaboration.

The Euro 4-million (US$4.9 million) project funded by the German Society for International Co-operation (GIZ) worked with the Vietnamese Government to mainstream ecosystem-based measures into pilot models in Hà Tĩnh and Quảng Bình provinces.

“After three years of implementation, the project evaluated the vulnerable ecological situation in Hà Tĩnh and Quảng Bình provinces,” Chinh said.

“The project also helped to set up a national plan of land use for 2016-2020, and an updated action plan for climate change preparedness until 2020 in the provinces,” he added.

The EbA project aims to support efforts in the strategic mainstreaming of ecosystem-based approaches into national policies on climate change adaptation, land-use and development planning.

EbA has been identified as an effective adaptation measure given that Việt Nam is heavily affected by the adverse effects of climate change.

Climate change vulnerability assessments have been conducted at both provincial and commune levels to introduce appropriate EbA solutions for implementation in the selected provinces.

From 2016, the project began pilot EbA activities in coastal areas suffering erosion and sand movement in Quảng Bình Province by planting and rehabilitating coastal forests in combination with livelihood activities, such as cattle-raising, fresh- water fish farming, and vegetable cultivation.

In Hà Tĩnh, the project piloted EbA approaches in a mountain ecosystem under drought conditions, enriching natural forest by using indigenous plants, oranges and pineapples grown in contour lines – plus bee-raising.

The two areas selected for the pilot EbA approaches shared common characteristics. Firstly, the communities in both areas showed real enthusiasm to participate; and secondly, they lived in areas suffering from difficult economic conditions, with limited access to the technologies required for agricultural production.

Strengthening the capacity of stakeholders at central and local levels was a key aspect of the project.

To improve knowledge and the sharing of information on EbA measures and activities, the project organised a series of training workshops on mainstreaming them into the development planning process.

The project also focused on mainstreaming EbA into the climate-change-adaptation legal framework by supporting Government agencies. For example, the Department of Land Management will implement strategic environmental assessments to collect inputs for revising national land-use planning for 2016-2020; the Department for Planning Management will mainstream EbA and climate-change issues into developing the Planning Law; and the departments of Natural Resources and Environment of Hà Tĩnh and Quảng Bình will mainstream EbA into the updated Provincial Climate Change Action Plans to 2020.

Ivo Litzenberg, GIZ expert, said after three years of implementation, the two provinces had cleaner water resources and a healthier ecological system which was less vulnerable to climate-change impacts.

Land erosion was also reduced, which helped local people produce rice crops on slopes, said Litzenberg.

The project had also helped local people understand the importance of production thast was less harmful to ecological systems, he said.

Meanwhile, according to Phan Lam Sơn, deputy head of Hà Tĩnh Province’s Natural Resources and Environment Department, the project helped people become aware of main reasons for climate change, such as improper use of natural resources, waste discharge and polluting the environment.

Việt Nam was assessed as one of nations worst affected by climate change.

If the sea water level rise by one metre, 40 per cent of land area in Cửu Long (Mekong) Delta, 11 per cent of land in the Hồng Delta, and 3 per cent of land areas along other coastal regions would be submerged.

About 10-12 per cent of population would be affected and losses would account for 10 per cent of the country’s GDP, said experts.

Understanding the consequences, the Government has issued several legal documents to deal with the situation, including a National Programme on Climate Change Preparedness, National Strategy on Climate Changes, National Strategy on Natural Calamity Reduction by 2020. — VNS

Bigger, Faster Avalanches, Triggered by Climate Change

When 247 million cubic feet of snow and ice collapsed off a glacier in the dry, mountainous region of western Tibet in 2016, the roiling mass took with it nine human lives and hundreds of animals, spreading more than five miles in three minutes at speeds of nearly 200 miles per hour. The event surprised scientists, who had seen a collapse that big and that fast only once before.

Fighting climate change with bioenergy may do ‘more harm than good’

Mongabay.com

  • A new study finds land-use like grazing and managing forests for resource extraction may have released more carbon than previously thought. Its results indicate the world’s terrestrial vegetation is currently sequestering less than half its full carbon-storage potential.
  • Of that missing half, the researchers discovered 42 to 47 percent is attributed to land uses that don’t technically change the vegetation cover type. The researchers say that climate change mitigation strategies often focus on reducing intensive land-use like deforestation, with less-intensive uses that don’t change cover type largely overlooked and under-researched.
  • One of these less-intensive uses is managing forests for biomass energy production. Many countries are trying to replace fossil fuels with biomass energy in-line with international climate agreements like the Paris Accord.
  • The researchers warn that strategies developed under the assumption that producing biomass energy doesn’t come at a carbon cost could harm efforts to fight climate change. They urge that in addition to stopping deforestation, the protection of forest functions, like carbon stocks, should be moved more into focus when it comes to land-use and climate change planning.

As nations try to stem emissions to keep the world from warming more than 2 degrees Celsius in line with their commitments towards the Paris Accord, replacing fossil fuels with renewable alternatives is widely seen as a big step in the right direction. A major source of energy oft-extolled as renewable is biomass from trees, which are usually harvested from managed forests either established on land that has already been deforested or planted where forests didn’t naturally grow. But a new study finds land-use like managing forests for biomass production may come at a much higher carbon cost than previously thought.

Climate change is triggering a migrant crisis in Vietnam

Theconversation

The Vietnamese Mekong Delta is one of Earth’s most agriculturally productive regions and is of global importance for its exports of rice, shrimp, and fruit. The 18m inhabitants of this low-lying river delta are also some of the world’s most vulnerable to climate change. Over the last ten years around 1.7m people have migrated out of its vast expanse of fields, rivers and canals while only 700,000 have arrived.

On a global level migration to urban areas remains as high as ever: one person in every 200 moves from rural areas to the city every year. Against this backdrop it is difficult to attribute migration to individual causes, not least because it can be challenging to find people who have left a region in order to ask why they went and because every local context is unique. But the high net rate of migration away from Mekong Delta provinces is more than double the national average, and even higher in its most climate-vulnerable areas. This implies that there is something else – probably climate-related – going on here. Tiếp tục đọc “Climate change is triggering a migrant crisis in Vietnam”

PENANG, Malaysia, Jan 2 2018 (IPS) – Another new year has dawned, and on a world facing serious disruption on many fronts.  What are the trends and issues to watch out for in 2018?

One obvious answer is to anticipate how Donald Trump, the most unorthodox of American Presidents, will continue to upset the world order.  But more about that later.

Just as importantly as politics, we are now in the midst of several social and environmental trends that have important long-lasting effects.  Some are on the verge of reaching a tipping point, where a long-term trend produces critical and sometimes irreversible events. We may see some of that in 2018.
