The article profiles researcher Vaclav Smil in relation to his thought of the past and future of energy production and energy transitions. Topics include Smil's thought on climate change mitigation, his views on the history of fossil fuel use, and his opinions on the potential of renewable energy in relation to its environmental impacts. The views of businessman Bill Gates on Smil are noted.

The article focuses on ideas of preventing climate change impacts discussed at a meeting at Montana State University (MSU) in Bozeman, Montana. Topics include plantations of crops, sown to capture carbon dioxide (CO2 from the atmosphere, developments of negative emissions technologies (NETs) to mitigate global warming such as bioenergy with carbon capture and storage (BECCS), presenting the view of Naomi Vaughan of University of East Anglia in Norwich, England on the issue.

The article discusses the notion of sensitive intervention points (SIPs) in relation to climate change prevention and socioeconomic events. Topics include the significance of nonlinear aspects of social change, investments in clean energy technologies, and the passage of a Climate Change Act in 2008 in Great Britain.

The article discusses hydrogen generation by an electrochemical membrane reactor to prevent climate change. It includes stripping hydrogen from more convenient carriers, including ammonia, methane, and biomass. These fuels could be delivered to the point of need by using an existing infrastructure, where they could then be converted to hydrogen for use in fuel cells.

Afforestation and forest management are considered to be key instruments in mitigating climate change. Here we show that since 1750, in spite of considerable afforestation, wood extraction has led to Europe's forests accumulating a carbon debt of 3.1 petagrams of carbon.We found that afforestation is responsible for an increase of 0.12 watts per square meter in the radiative imbalance at the top of the atmosphere, whereas an increase of 0.12 kelvin in summertime atmospheric boundary layer temperature was mainly caused by species conversion. Thus, two and a half centuries of forest management in Europe have not cooled the climate. The political imperative to mitigate climate change through afforestation and forest management therefore risks failure, unless it is recognized that not all forestry contributes to climate change mitigation.

The article reports that researchers in Washington, D.C. and Los Angeles in the United States and Madrid in Spain were arrested after demonstrations organized by the coalition Scientist Rebellion due to governments' failure to stop climate change.

The article discusses the creation of hydrogen using electrically heated reactors, noting research in an issue article by S. T. Wismann et al. Topics include the role of electrification in mitigating climate change, the use of renewable energy sources and energy storage, and the conversion of electricity to heat.

PHOTO (COLOR): President Donald Trump is moving forward with his plan to withdraw the United States from the Paris climate pact. Today's move has been expected ever since President Donald Trump stood in the White House Rose Garden on 1 June 2017, and blasted the global climate pact as a bad trade deal for the United States.

The article examines the potential and limitations of the planned planetary-scale carbon dioxide removal (CDR) from the atmosphere. It cites several proven strategies for limiting climate change, including enhancing energy efficiency and capturing wind and solar energy. It elaborates on the categories under which CDR fall into, which include the more mature strategies and engineered approaches. The drawbacks of CDR are also discussed.

Highlights from the article: Trees in forests where elephants live had denser wood by about 75 grams per cubic meter than those in forests without elephants. Even just one elephant per square kilometer could increase the amount of plant mass in the forest by up to 60 tons per hectare, enough to suck up more than 10 billion tons of planet-warming carbon dioxide across Africa's 2.2 million square kilometers of forest.

The article reports on the results of a May 18, 2019 election in Australia in relation to the lack of climate change prevention policies proposed by the Liberal-National coalition that won the election.

The article discusses efforts by U.S., Saudi Arabia, and Brazil representatives to block a study of geoengineering methods of climate change prevention at a United Nations environmental summit in Nairobi, Kenya.

The article reports on March 15, 2019 student protests to call for climate change prevention policies, noting support for the protests by scientists.

The article focuses on the development and implementation of the 2015 Paris Agreement (PA) to combat climatic changes. It states that diplomats meeting in November 2017 need to focus on the infrastructure of data and analysis necessary as the PA becomes operational. It comments on the decentralized nature of the PA and efforts to help policy-makers deal with climatic changes as a matter of risk-management. They talk about the use of Bayesian methodology in developing reliable risk indicators.

The article discusses the challenges in U.S.'s effort to reduce its greenhouse gas emissions for a 2025 goal, as established at the international climate agreement to limit climate change at the Paris, France summit in 2015.

The article discusses research on the role of rewilding in mitigating climate change. Topics include the significance of herbivore grazing in preventing forest fires, research about ancient habitats, and the impact of warming on Arctic tundra that is being overgrown by shrubs. Problems with predicting the results of rewilding are noted.

The article discusses the U.S. government body Global Change Research Program's recommendations that the U.S. should fund research on geoengineering to prevent climate change, including through reducing carbon in the atmosphere and improving Earth's albedo [ABSTRACT FROM PUBLISHER]

The article reports that only 56 nations have submitted pledges to reduce greenhouse gas emissions to the United Nations three months prior to a scheduled gathering of 195 nations in Paris, France to finalize a new international deal to reduce climatic changes.

The article discusses why the U.S. National Research Council (NRC) has announced that the U.S. government should fund research in the field of climate engineering. Topics include the concept of albedo modification through such methods as making clouds more reflective, how the Department of Energy has pulled funding initiatives for similar research in the past for fear of bad publicity, and how climate change skeptics have impacted research.
