The Euclid Avenue United Methodist Church in Oak Park, Illinois, transitioned toward net-zero energy by replacing a gas boiler with a $350,000 geothermal heat pump system in 2011, which reduced annual gas costs by $11,500 and greenhouse gas emissions by 81%. To offset the resulting increase in electricity demand, the church installed a 35-kW rooftop solar system in 2014 and later subscribed to a community solar farm in Rockford in 2021. Additional efficiency measures, including LED lighting and night setback temperature controls, further reduced electricity consumption by approximately 47,000 kWh annually.

Since 1970, all 50 U.S. states and 241 analyzed cities have warmed, with the contiguous U.S. increasing by 2.5°F. While states reduced greenhouse gas emissions by an average of 19% between 2005 and 2020, the current pace of reduction is insufficient to meet the national target of a 50% reduction by 2030.

In 2022, global electricity reached its lowest emissions intensity ever at 436 gCO2/kWh, with wind and solar hitting a record 12% of generation. Despite this, total power sector CO2 emissions reached a record high of 12,431 mtCO2 because wind and solar growth could not fully keep pace with a 2.5% increase in global electricity demand. This gap was filled by coal and other fossils, with coal generation rising by 108 TWh to a record 10,186 TWh. While clean electricity sources other than wind and solar saw their first year-on-year decline since 2011 due to nuclear outages and droughts, 2022 is characterized as an 'accelerator year' due to policy shifts like the EU's REPowerEU and the US Inflation Reduction Act.

The European Central Bank's (ECB) March 2023 climate disclosures reveal that its corporate asset portfolios have not decarbonized at a pace matching European climate goals, with total carbon emissions increasing by approximately 88% between 2018 and 2022. The report argues that the ECB's 'climate tilting' framework is insufficient because it only applies to reinvestments rather than the existing stock of assets and fails to exclude fossil fuel developers. To align with its 2021 climate roadmap, the author recommends that the ECB extend its climate approach to the stock of corporate bonds and exclude companies inconsistent with the 1.5°C objective.

The document analyzes how warming average annual minimum temperatures in the U.S. are shifting plant hardiness zones northward, affecting the geographic range of crops, invasive species, and pests. Based on an analysis of 242 U.S. locations from 1951 to 2022, it finds that 95% of these locations experienced warming, with some cities seeing significant zone shifts. This trend may expand the range of high-value crops but also facilitates the spread of invasive species like Kudzu and the brown marmorated stink bug.

The 2023 report by Global Energy Monitor and partners highlights a divergence in global coal trends: while most of the world is reducing coal capacity, China is significantly increasing its domestic pipeline. In 2022, China's under-construction coal capacity grew by 38%, while the rest of the world saw a 20% decrease. The report notes that 70% of OECD coal capacity is moving toward phase-out, but only 6% of non-OECD capacity is scheduled for retirement before 2040. In Pakistan, coal capacity grew from 150 MW in 2016 to 7.6 GW in 2023, with the government signaling a shift toward increasing local coal-based electricity capacity to 10 GW despite environmental and social concerns in the Thar region.

The report finds that while a majority of Americans (57%) have heard little or nothing about the Inflation Reduction Act (IRA), 68% of registered voters support it after learning about its goals. Support is particularly high among Black Americans (78%), Gen Z/Millennials (78%), and women (75%), groups that were also among the least familiar with the law. Politically, support is strongest among liberal Democrats (97%) and moderate/conservative Democrats (91%), while conservative Republicans are the least supportive (23%) despite having relatively high initial awareness.

The report finds that while a majority of registered voters (57%) have heard little or nothing about the Inflation Reduction Act (IRA), 68% support the law after learning about its goals. Support is particularly high among Black Americans, women, Gen Z/Millennials, and lower-income individuals, who are also among the groups least familiar with the legislation. Politically, the IRA sees strong support from liberal Democrats (97%), moderate/conservative Democrats (91%), and liberal/moderate Republicans (66%), while conservative Republicans are the least supportive (23%).

Atmospheric rivers are corridors of moisture that provide essential water resources to the western U.S. but also cause severe flooding and landslides. Climate change is increasing the intensity and moisture content of these storms, which is projected to raise annual flood damages in the western U.S. to between $2.3 and $3.2 billion by 2090. While a series of atmospheric rivers in early 2023 significantly reduced drought coverage in California, the trend toward warmer storms is reducing snowpack and increasing the risk of compounding climate hazards.

The document analyzes the failure of technology mandates to achieve 100% substitution of traditional brick kilns in Bangladesh, predicting that this goal will likely not be met by 2035 despite its priority in the updated Nationally Determined Contribution (NDC). It highlights that full conversion to energy-efficient kilns could reduce carbon dioxide emissions by 1177 kilotonnes, Black Carbon by 11 kilotonnes, and PM2.5 by 13 kilotonnes by 2030. Additionally, the paper maps the activities of development partners, finding they primarily focus on the 'Guidance of Search' and 'Creation of Legitimacy' functions of innovation systems.

The document outlines eight reasons why the UK should not increase its military spending, asserting that the UK and NATO already possess significant force advantages over Russia and China. It highlights recent budget increases, such as a £24bn boost in 2020, and criticizes the arbitrary nature of NATO's 2% GDP spending target. The author argues that funds would be better allocated to the National Health Service, overseas aid, and carbon emission reductions, noting that military spending is more than seven times the budget for reducing national carbon emissions.

Natural gas is the fastest growing source of CO2 emissions from fossil fuels, with methane leakage potentially making its climate impact equivalent to coal. To align with the 1.5°C goal, global gas production and consumption must decrease by 30% by 2030 and 65% by 2050, with developed countries phasing out gas power by 2035. The document rejects the use of gas as a bridge fuel or a solution to the 2022 energy crisis, noting that expanding infrastructure creates stranded asset risks, particularly for non-OECD countries. It further argues that converting gas infrastructure to hydrogen is technically unproven and economically inefficient, and highlights severe public health risks associated with gas extraction, flaring, and domestic use.

The guide advises consumers to first consider car-free alternatives to reduce costs and carbon emissions. For those who need a vehicle, it recommends the lowest-emission option, noting that EVs produce less than half the lifetime heat-trapping emissions of gasoline cars. It discusses the trade-offs between battery size and cost, explains three levels of charging (Level 1, Level 2, and DC fast charging), and addresses the impact of cold weather on battery range.

The Anabaptist Mennonite Biblical Seminary in Indiana has significantly reduced its carbon footprint and energy costs through a series of sustainable upgrades. Central to these efforts was the 2007 completion of a 31,500 square foot library, which became the first LEED-certified theological library in North America by utilizing a ground-source geothermal heat pump system and other high-performance design elements. Between 2013 and 2022, the seminary decreased its annual energy consumption by approximately two-thirds by implementing recommendations from an ASHRAE Level 2 energy audit, replacing outdated 1950s boilers with fuel-efficient models, and installing two solar arrays (50-kW and 80-kW) that have offset over 320 tons of carbon emissions.

The report finds broad support among registered U.S. voters for clean energy research, tax rebates for energy efficiency, and conservation policies, though views on offshore drilling and the Inflation Reduction Act of 2022 vary by political affiliation. While many voters believe corporations and government should do more to address global warming, few have engaged in significant political action in the past year, and only 11% believe the U.S. government is responding well to the issue.

A survey of 861 registered U.S. voters in Spring 2023 reveals broad support for clean energy research, tax rebates for energy efficiency, and local climate-friendly infrastructure. While 71% support the Inflation Reduction Act of 2022 after reading a description, only 11% believe the U.S. government is responding well to global warming. There is a significant gap between the willingness of voters to take political action and their actual engagement over the past year.

The report details a surge in EU gas infrastructure projects, including 30 fast-tracked LNG terminals and extensive pipeline networks, driven by the 'gas panic' after Russia's invasion of Ukraine. It warns that the proposed 227.2 bcm/y of additional LNG capacity would increase the EU's maximum import capacity by 136%, potentially costing €53.5 billion and emitting up to 950 million tons of CO2 annually. The document argues that these uncoordinated efforts, led by countries like Germany, Greece, and Italy, conflict with the EU's 'Fit for 55' climate goals and the European Climate Law. Additionally, it critiques the 'European Hydrogen Backbone' initiative, stating that repurposing methane pipelines for hydrogen is technically risky and economically unjustified, further entrenching fossil fuel use.

One year after the invasion of Ukraine, the EU has substituted nearly 75% of Russian gas imports and seen wind and solar generate a record 22% of its electricity in 2022. Globally, gas demand is forecast to peak by the end of the decade, with 88% of electricity demand growth to 2025 expected to be met by renewables. While renewable energy saved billions in fossil fuel costs, high gas and coal prices drove 90% of the global increase in electricity costs in 2022. Russia faces significant financial losses from sanctions, including a USD 25 billion public deficit in January 2023, while EU industrial production grew by over 2% on average despite a 15% drop in industrial gas demand.

The document asserts that the current cost of living crisis is driven by fossil fuel price volatility, particularly natural gas, rather than the costs of net-zero policies. It identifies that poorer households are disproportionately affected by energy poverty and argues that short-term government subsidies are insufficient. The briefing proposes that expanding renewable energy capacity, implementing building energy efficiency retrofits, installing heat pumps, and electrifying transport can lower energy bills, reduce market volatility, and enhance energy security.

The document describes the El Niño-Southern Oscillation (ENSO) as a natural climate pattern consisting of warm (El Niño), cold (La Niña), and neutral phases driven by sea surface temperatures and pressures in the tropical Pacific. It details how these phases disrupt atmospheric circulation, affecting global precipitation and temperature. Specifically, La Niña is associated with wetter conditions in Australia and Indonesia and warmer, drier winters in the southern U.S., while El Niño is linked to drought in Australia and Indonesia and cooler, wetter winters in the southern U.S. The text emphasizes that while ENSO can nudge global temperatures, it does not mask the long-term warming trend caused by carbon pollution; for instance, 2022 remained the sixth hottest year on record despite a persistent La Niña. Historical data from the 2015-2016 El Niño event highlights severe consequences, including forest fires in Indonesia, flooding in Peru, and an estimated 60 million people impacted by extremes across Africa, Latin America, the Caribbean, and the Asia-Pacific region.
