US Climate Action 2014 Report

As reported HERE, the U.S. Department of State submitted the 2014 U.S. Climate Action Report on Thursday to the United Nations Framework Convention on Climate Change (UNFCCC).

The report details actions the United States will take domestically and internationally to address climate change and reduce greenhouse gas emissions by 17 percent below 2005 levels by 2020. It also outlines President Obama's "Climate Action Plan" or CAP, which includes: cutting carbon pollution from power plants, doubling renewable electricity generated from wind and solar by 2020, and increasing clean energy research funding by $7.9 billion. Here is a graphic from the report showing the scenario of greenhouse gas emissions "to reach our goal of reducing U.S greenhouse emissions in the range of 17 percent below 2005 levels by 2020" including the CAP, in green.

In their declaration, the working group calls, “on all people and nations to recognize the serious and potentially irreversible impacts of global warming caused by the anthropogenic emissions of greenhouse gases and other pollutants, and by changes in forests, wetlands, grasslands, and other land uses.” Read summary here. View entire report here. Hear the Working Group co-chair, Veerabhadran Ramanathan interviewed by Coalition director, Dan Misleh.

Executive Summary This study provides an overview assessment of the potential economic costs of climate change impacts and adaptations to climate change in eight major economic sectors in New York State. These sectors, all of which are included in the ClimAID report are: water resources, ocean and coastal zones, ecosystems, agriculture, energy, transportation, communications, and public health. Without adaptation, climate change costs in New York State for the sectors analyzed in this report may approach$10 billion annually by midcentury. However, there is also a wide range of adaptations that, if skillfully chosen and scheduled, can markedly reduce the impacts of climate change by amounts in excess of their costs. This is likely to be even more true when non-economic objectives such as environment and equity are taken into account. New York State as a whole has significant resources and capacity for effective adaptation responses; however, given the costs of climate impacts and adaptations, it is important that the adaptation planning efforts that are now underway are continued and expanded.

NEW JERSEY - Preparing NJ for Climate Change

HERE are presentations from a workshop on climate held at Rutgers University. The keynote speaker was from the U.S. Navy Task Force on Climate Change:

“This workshop takes the first step in the development of a common information base and the creation of a network of New Jersey leaders and practitioners who will be better prepared to serve New Jersey communities, businesses, and other stakeholders as we begin to address the challenges of climate preparedness,” said Dr. Anthony Broccoli, director of the Climate and Environmental Change Initiative.

The initiative is a university-wide multidisciplinary research, education, and outreach effort focused on understanding the mechanisms that drive global and regional climate change; predicting the future of the climate system and the impacts of change, including those on a densely populated, coastal society; and informing society about the causes and consequences of climate change.

America's Climate Choices project

The America's Climate Choices project issued the final 2011 volume of the US National Research Council's most comprehensive study of climate change to date.

Here is the the Press Release:

WASHINGTON — Warning that the risk of dangerous climate change impacts is growing with every ton of greenhouse gases emitted into the atmosphere, a National Research Council committee today reiterated the pressing need for substantial action to limit the magnitude of climate change and to prepare to adapt to its impacts.  The nation's options for responding to the risks posed by climate change are analyzed in a new report and the final volume in America's Climate Choices, a series of studies requested by Congress.  The committee that authored the report included not only renowned scientists and engineers but also economists, business leaders, an ex-governor, a former congressman, and other policy experts.

You can read the book online, free. You can also download it:

PDF Summary

Report In Brief

Previously, (May 2010) three reports were issued. These reports can be read free online. Here are the links along with a summary description for each volume:

1. Advancing the Science of Climate Change

The compelling case that climate change is occurring and is caused in large part by human activities is based on a strong, credible body of evidence, says Advancing the Science of Climate Change, one of the new books in the America's Climate Choices series. While noting that there is always more to learn and that the scientific process is never "closed," the book emphasizes that multiple lines of evidence support scientific understanding of climate change.

The core phenomenon, scientific questions, and hypotheses have been examined thoroughly and have stood firm in the face of serious debate and careful evaluation of alternative explanations, the book says.

2. Adapting to the Impacts of Climate Change

Reducing vulnerabilities to impacts of climate change that the nation cannot, or does not, avoid is a highly desirable strategy to manage and minimize the risks, says the book, Adapting to the Impacts of Climate Change. Some impacts--such as rising sea levels, disappearing sea ice, and the frequency and intensity of some extreme weather events like heavy precipitation and heat waves--are already being observed across the country.

The book notes that policymakers need to anticipate a range of possible climate conditions and that uncertainty about the exact timing and magnitude of impacts is not a reason to wait to act. In fact, it says boosting U.S. adaptive capacity now can be viewed as "an insurance policy against an uncertain future," while inaction could increase risks, especially if the rate of climate change is particularly large.

3. Limiting the Magnitude of Future Climate Change

Substantially reducing greenhouse gas emissions will require prompt and sustained efforts to promote major technological and behavioral changes, says Limiting the Magnitude of Future Climate Change, a new book from the America's Climate Choices study. Although limiting emissions must be a global effort to be effective, strong U.S. actions to reduce emissions will help encourage other countries to do the same.

In addition, the U.S. could establish itself as a leader in developing and deploying the technologies necessary to limit and adapt to climate change.

Global Climate Change Impacts in the United States

Global Climate Change Impacts in the United States (U. S. Global Change Research Program). The most comprehensive, authoritative report on Global Climate Change Impacts in the United States was released on Tuesday June 16th, 2009. This report presents, in plain language, the science and impacts of climate change on the United States, now and in the future. It focuses on climate change impacts on U.S. regions and various aspects of society and the economy such as energy, water, agriculture, and health. A comprehensive series of web-pages were developed that highlight the findings and major conclusions of the report and contain complete downloadable files of the report, as well as a host of additional content on climate change impacts on the U.S.

State of the Climate in 2009 (NOAA, UK MET)

### Unmistakable signs of a warming world

Now for the first time, a report has brought together all the different ways of measuring changes in the climate. The ten indicators of climate change include measurements of sea level rise taken from ships, the temperature of the upper atmosphere taken from weather balloons and field surveys of melting glaciers.

New technology also means it is possible to measure the temperature of the oceans, which absorb 90 per cent of the world's heat.

The State of the Climate report shows “unequivocally that the world is warming and has been for more than three decades”.

And despite the cold winter in Europe and north east America, this year is set to be the hottest on record.

HERE is the report which can be downloaded free.

### PBL (Netherlands) investigation of IPCC Regional Climate-Change Impacts

Key findings of IPCC on regional climate-change impacts overall considered well founded

"The PBL Netherlands Environmental Assessment Agency has investigated the scientific foundations for the IPCC summary conclusions of the Fourth Assessment Report of 2007 on projected regional climate-change impacts, at the request of the Dutch Minister for the Environment. Overall the summary conclusions are considered well founded, none have been found to contain any significant errors. The Working Group II contribution to the Fourth Assessment Report shows ample observational evidence of regional climate change impacts, which have been projected to pose substantial risks to most parts of the world, under increasing temperatures." HERE is the press release, HERE is the press conference presentation and HERE is the report.

### Climate Change Science Compendium 2009

The Climate Change Science Compendium is a review of some 400 major scientific contributions to our understanding of Earth Systems and climate that have been released through peer-reviewed literature or from research institutions over the last three years, since the close of research for consideration by the IPCC Fourth Assessment Report.

The Compendium is not a consensus document or an update of any other process. Instead, it is a presentation of some exciting scientific findings, interpretations, ideas, and conclusions that have emerged among scientists.

Focusing on work that brings new insights to aspects of Earth System Science at various scales, it discusses findings from the International Polar Year and from new technologies that enhance our abilities to see the Earth’s Systems in new ways. Evidence of unexpected rates of change in Arctic sea ice extent, ocean acidification, and species loss emphasizes the urgency needed to develop management strategies for addressing climate change.
