Liberal philanthropy is dooming the planet to climate disaster

EXCLUSIVE: Liberal philanthropy is dooming the planet to climate disaster, documents reveal

A 2017 paper in Science lead authored by Johan Rockström, director of the Potsdam Institute for Climate Impact Research, concluded that global carbon emissions would have to be cut in half by 2020, then cut in half again by 2030, and then cut in half again each decade out to 2050.
This entails that emissions should be slashed by about 75 percent by 2030, and by nearly 95 percent by 2050 to stay within a safe climate.
A Nature Geoscience study similarly found that “limiting warming to 1.5C is not yet a geophysical impossibility, but is likely to require delivery on strengthened pledges for 2030 followed by challengingly deep and rapid mitigation.” Read More

We have, on this planet, vast renewable energy potential: First and foremost, the solar energy resource is very large (Perez et al., 2009a). Figure 1 compares the current annual energy consumption of the world to (1) the known planetary reserves of the finite fossil and nuclear resources, and (2) to the yearly potential of the renewable alternatives. The volume of each sphere represents the total amount of energy recoverable from the finite reserves and the annual potential of renewable sources.

While finite fossil and nuclear resources are very large, particularly coal, they are not infinite and would last at most a few generations. More

Threatened by rising seas, small island nations appeal for more aid at UN

25 September 2013 – On the front line of damage wrought by climate change, threatened with extinction from rising seas, leaders of some of the world’s small island States took to the podium at the United Nations General Assembly today to call urgently for greater international support to mitigate the perils.

“Disastrously off course,” “profound disappointment” and “moral failure” were some of the terms used by heads of Small Island Developing States, known as SIDS, to depict their situation as the 68th General Assembly prepares to draw up long-term development plans for the decades after the end in 2015 of the current cycle of the anti-poverty Millennium Development Goals (MDGs).

“The corresponding actions to address the unique and special circumstances of SIDS by the international community has been lacking,” the Prime Minister of Antigua and Barbuda, Winston Baldwin Spencer, told the Assembly’s annual General Debate, summing up the almost two decades since the Barbados Programme of Action was adopted by at a UN conference on the sustainable development of SIDS in 1994.

“It is a recognized fact, but it is worth repeating that small island States contribute the least to the causes of climate change, yet we suffer the most from its effects. Small island States have expressed our profound disappointment at the lack of tangible action,” he said referring to efforts in UN climate change talks to protect SIDS and other vulnerable countries.

“Developed countries should shoulder their moral, ethical and historical responsibilities for emitting the levels of anthropogenic greenhouse gases into the atmosphere. It is those actions which have now put the planet in jeopardy and compromised the well-being of present and future generations,” the Caribbean leader stressed.

Noting uneven progress in achieving the MDGs, Prime Minister Kamla Persad-Bissessar of Trinidad and Tobago, who is also chairperson of Conference of Heady of State and Government of the Caribbean Community (CARICOM), warned that current approaches will not advance the MDG agenda by 2015 or ensure sustainable development in the post-2015 context.

“SIDS have made significantly less progress in the area of development, than other vulnerable groups of countries. In some cases SIDS are on the frontlines of experiencing a reversal of many of the gains that have been achieved,” she said.

“Indeed in the preparations for our participation in that upcoming discourse (on the Post-2015 Development Agenda), the recognition of the vulnerabilities of small island developing States is one of the guidelines that CARICOM will apply when considering its commitments to the overall Agenda.”

From the other side of the planet, Kiribati President Anote Tong, stressing the “real and existential threat” his low-lying Pacific nation faces from rising seas, called for immediate international action to mitigate climate change and rising sea levels.

“We are disastrously off course. The scientists tell us that calamity awaits – and not just for those of us on low-lying islands,” he said. “What we are experiencing now on these low-lying atolls is an early warning of what will happen further down the line. No one will be spared. We cannot continue to abuse our planet in this way. For the future we want for our children and grandchildren, we need leadership.

“We need commitment. And we need action ....now,” he declared, noting that while Kiribati is taking adaptation measures to remain habitable for as long as possible, it is also looking to improve its people’s skills to a level where they can compete for jobs in the international labour market with dignity if the rising ocean forces them to migrate.

“All those countries with the ability to do so must contribute to the prevention of this calamity, or be forever judged by history.” More

Small Islands Push for New Energy

ST. JULIAN’S, Malta, Sep 14 2012 (IPS) - Most islands are well endowed with one or more renewable energy source – rivers, waterfalls, wind, sunshine, biomass, wave power, geothermal deposits – yet virtually all remain heavily or entirely reliant on imported fossil fuels to produce electricity and power transport.

With rising oil prices, fuel import bills now represent up to 20 percent of annual imports of 34 of the 38 small island developing states (SIDS), between 5 percent to 20 percent of their Gross Domestic Product – and even up to 15 percent of the total import bills of many of the European Union’s 286 islands.

Action advocated under ‘The Malta Communiqué On Accelerating Renewable Energy Uptake For Islands’ adopted by a 50-nation two-day conference that ended here last week will hopefully slash, in some cases eliminate, reliance on fossils and related pollution, while increasing energy security, employment as well as economic and social wellbeing.

‘The Renewables and Islands Global Summit’ in Malta was co-hosted by the 100-nation International Renewable Energy Agency (IRENA) based in Abu Dhabi and by the government of Malta – a 316 sq km Mediterranean island republic of 410,000 inhabitants, and EU’s smallest member state.

With rising oil prices, fuel import bills now represent up to 20 percent of annual imports of 34 of the 38 small island developing states (SIDS),

The meeting represents a key milestone in IRENA’s initiative on renewables and islands launched by its governing council last January, as well as a follow-up to the Rio+20 conference in June and the ‘achieving sustainable energy for all in Small Island Developing States’ ministerial meeting in Barbados in May.

The communiqué invites IRENA to establish a global renewable energy islands network (GREIN) as a platform for sharing knowledge, best practice, challenges and lessons learnt while seeking innovative solutions.

GREIN will also help assess country potential, build capacity, formulate business cases for renewables deployment involving the private sector and civil society while identifying available finance as well as new ideas for innovative financing mechanisms.

In addition, the network will develop methodologies for integrating renewables into sustainable tourism, water management, transport, and other industries and services.

IRENA’s Kenyan director-general Adnan Amin told the 120 delegates that “we have confirmed the enormous potential for renewables in small island developing states as well as for developed island countries, not to mention coastal countries with remote, energy-deprived islands of their own. Ambitious policy targets appear increasingly attainable because of great strides forward in technology and cost-effectiveness.

“We are laying the groundwork for a business council to bring investors – from major energy companies to innovative SMEs (small and medium-sized enterprises) and also financial institutions – into the discussion,” Amin added. “Academics and NGOs can also contribute to the search for practical solutions. Developed island states can do much by sharing their experience with small-island developing states that face broadly similar challenges.”

Representatives (including 15 ministers) from 26 developing Pacific, Caribbean and African developing island nations and from coastal developing states with islands reported a wide range of renewables deployment, from detailed long-term plans and ongoing activities to reach up to 100 percent renewables, to admissions of very low deployment and no firm goals or plans yet.

West African Cape Verde, a 10-island 4,033 sq km archipelago with 491,000 inhabitants, has started working towards 100 percent, then possibly 300 percent renewables, according to José Brito, senior adviser to Cape Verde’s Prime Minister, José Maria Neves. Surplus energy remaining from meeting domestic needs (including seawater desalination) could either be stored or exported, Brito said. Cape Verde aims to become a renewables training hub for Africa.

Dominica in the East Caribbean (71,000 inhabitants, 754 sq km) could also become a net energy exporter, Crispin Grégoire, its former ambassador to the UN and now a United Nations Development Programme (UNDP) official in charge of Caribbean issues told IPS.

“With 325 rivers and mountainous terrain, we have huge hydroelectric potential. Moreover, Iceland and the EU are helping assess our extensive geothermal resources. We could export surplus electricity by interconnector seabed cable to Guadelupe and Martinique, each just 60 km away. We could also attract high-tech industries to use our surplus power.” More
