Most serious birdwatchers can tell you about global warming and climate change, just from watching the birds at their feeders, and when those birds migrate.

Now comes a study to confirm with data and controlled observation what the birders have been saying all along. Phys.org reported:

Scientists have shown for the first time that common bird populations are responding to climate change in a similar pronounced way in both Europe and the USA.

An international team of researchers led by Durham University, UK, found that populations of bird species expected to do well due to climate change had substantially outperformed those expected to do badly over a 30 year period from 1980 to 2010.

The research, conducted in collaboration with the RSPB and the United States Geological Survey (USGS), is published in the journal Science.

It is the first real demonstration that climate is having a similar, large-scale influence on the abundance of common birds in widely separated parts of the world, the researchers said.

Among the species showing pronounced effects of climate change are common woodland and garden birds such as the wren, in Europe, and the American robin in the USA.

Biologists especially work to predict effects of warming on plants and animals, both to help plan changes in activities such as farming and hunting, and to protect species that are endangered now, or are likely to become so due to changing climate factors.

This study shows scientists can predict with accuracy some of the wildlife effects.

These changes are consistent with changing climate suitability within those areas, the researchers said.

Other factors, such as the size of the birds, the habitats they live in and their migratory behaviour, all affect , but did not differ systematically between groups advantaged or disadvantaged by climate change.

Therefore, only climate change could explain the differences between average population trends in advantaged and disadvantaged groups, the researchers said.

The study’s lead authors, Dr Stephen Willis and Dr Philip Stephens, of Durham University’s School of Biological and Biomedical Sciences, said the findings showed there was a large-scale, consistent response by bird populations to climate change on two continents.

The study was published in the April 1, 2016 issue of Science, “Consistent response of bird populations to climate change on two continents.

Why not a price on carbon, a tax with cap-and-trade capabilities?

October 29, 2015

Tax on air pollutants with a cap-and-trade process worked wonders cleaning up acid rain in the U.S.  Is there any rational reason to oppose such a plan, in the U.S. or anywhere else, to help clean up carbon air pollution to slow or stop global warming?

Germany’s Chancellor Angela Merkel issued a call for a carbon pricing system. Who will listen?

It’s a feature story from World Bank, who seems to have figured out that global warming poses great threats to commerce and growing the world’s economies.

Heads of State, City, Regional and Business Leaders Unite to Call for Price on Carbon

October 19, 2015

For the first time Heads of State, city and provincial leaders have come together with the support of leading companies to urge countries and companies around the world to put a price on carbon pollution.

For the first time Heads of State, city and provincial leaders have come together with the support of leading companies to urge countries and companies around the world to put a price on carbon pollution.


STORY HIGHLIGHTS
  • Carbon pricing is a key building block to tackle climate change and drive investment in a low carbon future.
  • Launched today, the Carbon Pricing Panel is an unprecedented alliance of Global Leaders united to put a price on carbon pollution.
  • The number of implemented or scheduled carbon pricing instruments has nearly doubled since 2012, reaching an aggregate market value of about $50 billion.

What can be done to reduce greenhouse gas emissions, protect our environment, and help support people most vulnerable to climate change?

The answer is simple: A key element for any strategy to tackle climate change must be to put a price on carbon pollution. The transition to a cleaner future requires government action and the right incentives. Carbon pricing is a key building block to help cut pollution and drive investment in a low carbon future.

It’s a point recognized by leaders from Europe, across to Africa and Asia, who have today – for the first time – come together with the support of leading private companies to urge countries and businesses around the world to put a price on carbon.

Convened by World Bank Group President Jim Yong Kim and the International Monetary Fund’s Managing Director Christine Lagarde, the high-level Carbon Pricing Panel is calling on their peers to follow their lead and put a price on carbon. They are joined in this effort by OECD Secretary General Angel Gurria.

The call by the leaders comes on the first day of the last round of negotiations ahead of the Paris climate talks in December. The leaders aim to seize the momentum generated by the Paris talks to spur further, faster action towards carbon pricing, as a necessary path to a low carbon, productive, competitive economy of the future.

Members of the Carbon Pricing Panel include German Chancellor Angela Merkel, Chilean President Michelle Bachelet, French President François Hollande, Ethiopian Prime Minister Hailemariam Desalegn, Philippines President Benigno Aquino III, Mexican President Enrique Peña Nieto, Governor Jerry Brown of California, and Mayor Eduardo Paes of Rio de Janeiro.

Private sector support is spearheaded by Anne Stausboll, CEO of US Institutional Investor CalPERS, Gérard Mestrallet, CEO of ENGIE of France, Anand Mahindra, Chairman and Managing Director of Mahindra Group of India, and Feike Sijbesma, Chairman and CEO of Netherlands-based Royal DSM.


” There has never been a global movement to put a price on carbon at this level and with this degree of unison. It marks a turning point from the debate on the economic systems needed for low carbon growth to the implementation of policies and pricing mechanisms to deliver jobs, clean growth and prosperity. The science is clear, the economics compelling and we now see political leadership emerging to take green investment to scale at a speed commensurate with the climate challenge. “

Around the world, about 40 nations and 23 cities, states and regions have implemented or are putting a price on carbon with programs and mechanisms covering about 12 percent of global greenhouse gas emissions.

The number of implemented or scheduled carbon pricing instruments has nearly doubled since 2012, reaching an aggregate market value of about $50 billion.

And already more than 400 businesses around the world are using a voluntary, internal price on carbon as part of their investment strategies, with prices ranging from US$4 to over US$100 per ton of CO2. This is a tripling in the number of companies compared with last year reporting that they price their emissions.

Carbon pricing delivers a triple dividend.

Firstly, it is good for the environment and it reduces emissions – lowering social costs of health impacts on people, as well as tackling the global warming.  A price on carbon can help alleviate health and environmental problems like premature deaths from exposure to outdoor air pollution. According to the World health Organization, an estimated 3.7 million people die prematurely from outdoor air pollution.

Secondly, carbon pricing is an essential part of getting prices right for the move to a low carbon more resilient growth. It raises revenue efficiently, making it possible to reduce more distortionary taxes, and it allows for targeted support for clean energy solutions rather than harmful subsidies that do little for poor people or the environment.

And thirdly, it drives innovation and critically needed investments in low-carbon solutions, boosting private sector investment in clean tech research and development, and offering the prospect of job creation in the sectors of the future.

Why is is it important to act now on carbon pricing? Because strong public policy gives the private sector the certainty and predictability to make the necessary long-term investments in climate-smart development and prevent catastrophic impacts from climate change. Carbon pricing is the cornerstone of a package of policy measures designed to achieve emission reductions at lowest cost.

Today, countries and regions are learning from one another and creating a set of successful approaches to pricing carbon. Some early lessons are described in the World Bank Group publication The FASTER Principles for Successful Carbon Pricing – which lays out principles for effective, efficient and fair pricing of carbon.

Some examples include:

  • The Canadian province of British Columbia was an early mover on carbon pricing, with the creation of a carbon tax in 2008, with the tax used to cut income taxes and fund tax credits. Also, British Columbia is home to a growing clean technology sector, with more than 150 firms in 2013, accounting for 22% of Canada’s clean tech presence in a province with only 12% of Canada’s GDP. Several experts attribute this growth to the carbon tax.
  • California, Quebec and the European Union allocate a portion of their emissions trading scheme (ETS) auction revenues to designated green technology funds and innovation, to support sectors affected directly or indirectly by higher carbon costs.
  • In Chile, the government has passed legislation on a carbon tax – effective as of 2017 – as part of a much larger tax reform package with the explicit aim of providing additional resources for education and other social protection programs.
  • In Northeastern United States, the Regional Greenhouse Gas Initiative is expected to save people money on energy bills. The RGGI states have invested over $1 billion from ETS proceeds in energy-efficiency program, which are expected to return more than $2.3 billion in lifetime energy bills savings to 1.2 million participating households. Also, from 2008-2012, RGGI invested more than $130 million to help energy and electricity customers in need.

The high level panel provides political momentum to complement the voices of government and industry leaders in the Carbon Pricing Leadership Coalition (CPLC), a working coalition that is being formed on the back of support for carbon pricing from 74 countries and 1,000 companies, at the 20014 UN summit on climate change.

Putting a price on carbon can be done in many ways: using an emissions trading system (ETS), like the one in Europe, or introducing carbon taxes and fees, like in Sweden and Norway. Most importantly, the “polluter pays” principle applies – those who are responsible for the pollution face the cost of it.


Annals of global warming: Would you worry if it shrinks your paycheck?

MarketWatch’s Silvia Ascarelli wrote:

Your grandchildren may pay a bigger price for global warming than you thought.

A hotter Planet Earth will cool down national economies, according to fresh research from scientists at Stanford University and the University of California, Berkeley.

Average U.S. income could shrink 36% by 2100 because of climate change from what it would be without global warming, they say. That is more than other, earlier studies have suggested.

But not all countries will suffer. Russia, Canada and countries in Northern Europe should benefit from warmer temperatures, according to the scientists’ models, because they have yet to reach what the scientists called the optimal average temperature for an economy — 55 degrees Fahrenheit, roughly where the U.S. is now.

“We were surprised at how important temperature is for the global economy,” said Solomon Hsiang, an associate professor of public policy at Berkeley and one of the co-authors of the study along with Marshall Burke, an assistant professor in earth system science at Stanford, and Edward Miguel, Oxfam professor in environmental and resource economics at Berkeley.

Global per capita gross domestic product will be down 23% at the turn of the next century if global warming isn’t slowed, the study found. The impact will be more severe in China — average income will shrink 43%—and Mexico, where average income could plunge 73%.

Annals of Global Warming: Warm the oceans, raise the sea level

September 15, 2015

Svein T veitdal is one of those rare scientists who can explain why science observations are important in effects on people in just living their lives. A good man to listen to (you can follow his Twitter account: @tveitdal).

Recently he sent this notice:

Critics of the science of climate change and the work to slow or halt warming don’t like charts like that. Sea level is something measured by humans, worldwide, for a long time. That’s real data.

And it’s scary.

T veitdal’s Tweet was just a small part of a very large graphic from NASA, explaining the observations that tell us sea levels rise, how the observations are made, and what it means to you and me.

NASA infographic on sea level rise

NASA infographic on sea level rise: We know seas are rising and we know why. The urgent questions are by how much and how quickly. Available to download, this infographic covers the science behind sea level rise, who’s affected, how much melting ice is contributing, and what NASA is doing to help.

Yeah. “Your planet is changing. We’re on it.”

As Ban-ki Moon said the other day, there is no Planet B. We have only one Earth.

Annals of Global Warming: A roadmap to the UN climate change treaty process

Alas, the U.S. has led a large contingent off-road.

From the Cut the Fluff blog:

If you stop the average climate change action opponent on the street (as many as 25 out of every 100 people, or every other person in Texas in my unscientific sample) they will be able to tell you they think scientists are all liars making big money off of scamming citizens and businesses, and that there is big money to be made in faking research. But they cannot seriously describe evidence to back their claims, nor can they describe the history of international work to stop human-caused warming.

As you might imagine, they cannot discuss the pending meetings in Paris, either. Heck, most scientists and well-informed people can’t explain the meetings, either.

I hope this helps.

“COP” and “UNFCC” are UN acronyms for Conference of the Parties to the United Nations Framework Convention on Climate Change.

The Sustainable Information Forum (SIF15) explains the Paris Conference In not-too-turgid prose:

COP – What’s it all about?

The international political response to climate change began at the Rio Earth Summit in 1992, where the ‘Rio Convention’ included the adoption of the UNFCCC. This convention set out a framework for action aimed at stabilising atmospheric concentrations of greenhouse gases (GHGs) to avoid “dangerous anthropogenic interference with the climate system.” The UNFCCC which entered into force on 21 March 1994, now has a near-universal membership of 195 parties.

The main objective of the annual Conference of Parties (COP) is to review the Convention’s implementation. The first COP took place in Berlin in 1995 and significant meetings since then have included COP3 where the Kyoto Protocol was adopted, COP11 where the Montreal Action Plan was produced, COP15 in Copenhagen where an agreement to success Kyoto Protocol was unfortunately not realised and COP17 in Durban where the Green Climate Fund was created.

In 2015 COP21, also known as the 2015 Paris Climate Conference, will, for the first time in over 20 years of UN negotiations, aim to achieve a legally binding and universal agreement on climate, with the aim of keeping global warming below 2°C.

France will play a leading international role in hosting this seminal conference, and COP21 will be one of the largest international conferences ever held in the country. The conference is expected to attract close to 50,000 participants including 25,000 official delegates from government, intergovernmental organisations, UN agencies, NGOs and civil society.

Now you know, I hope.
