Annual Temperature Deviation from Average by County in the United States

The amount of carbon dioxide we have been dumping into the atmosphere rapidly grows over time. Atmospheric carbon dioxide has been measured to average about 260 ppm in the last 400 thousand years. Pre-industrial levels were approximately 280ppm, the industrial level was around 315. Today it is about 410 ppm. That is a 57.6 percent increase. Since 1901, the average surface temperature across the contiguous 48 U.S. states has increased at an average rate of 0.16°F (0.09°C) per decade. Average temperatures have grown faster since the late 1970s (0.31 to 0.54°F or 0.17 to 0.30 °ะก per decade since 1979). Eight of the ten leading warmest years on record for the contiguous 48 U.S. states have happened since 1998, and 2012 and 2016 were the two warmest years in history. Since the late 1970s, the U.S. has warmed faster than worldwide. Some parts of the United States have experienced more warming than others, primarily the West, North, especially Alaska.  Below is the visualization created by


The road net of the U.S. is one of the greatest human structures on earth (4 million miles in combined length, 1% of the land of the U.S). The map of the United States below codes distance from roads. Via

The companies responsible for the most global carbon emissions

The issue of global carbon emissions is complex, and there are various ways to measure and attribute responsibility to companies. However, based on different data sources and methodologies, here are some of the companies that have been identified as significant emitters of carbon dioxide (CO2) and other greenhouse gases (GHGs) globally: Saudi Arabian Oil Company (Saudi Aramco) - Saudi Aramco is a state-owned oil company in Saudi Arabia and is considered the world's largest oil producer. It has been identified as one of the top emitters of carbon emissions globally, with its oil extraction and refining operations being major contributors to greenhouse gas emissions. Chevron Corporation - Chevron is one of the world's largest oil and gas companies, headquartered in the United States. Its operations in oil and gas exploration, production, and refining have been associated with significant carbon emissions. Exxon Mobil Corporation - Exxon Mobil, also known as Exxon or ExxonMobil, i

100 companies are responsible for most of the world's greenhouse gas emissions

The countries responsible for the highest greenhouse gas (GHG) emissions globally are: China: China is the world's largest emitter of greenhouse gases, accounting for approximately 28% of global GHG emissions. This is primarily due to its heavy reliance on coal for energy production and industrial activities. United States: The United States is the second-largest emitter of greenhouse gases, responsible for around 15% of global GHG emissions. This is primarily due to its high levels of industrial and transportation emissions, as well as energy production from fossil fuels. European Union (EU): The EU, as a collective entity, is also a significant emitter of greenhouse gases, accounting for approximately 9% of global GHG emissions. The EU consists of 27 member states, and its emissions are primarily from transportation, industry, and agriculture. India: India is also a major emitter of greenhouse gases, responsible for around 7% of global GHG emissions. Its emissions primarily come

How global warming will impact 6000+ cities around the world?

London could feel as hot as Paris by 2050, with Paris’s climate more like San Francisco. San Francisco feeling like Melbourne and New York City like Bologna (Italy). Moscow will resemble Boston.  Global environmental stratification (GEnS), based on the statistical clustering of bioclimate data (WorldClim). GEnS consists of 125 strata, which have been aggregated into 18 global environmental zones (labeled A to R) based upon a statistical clustering of climate variables averaged from 1960 to 2000. 4 emission scenarios (RCP) were analyzed using the CIMP5 model predictions for the year 2050, ranging from RCP 2.6 (lowest emission scenario) to RCP 8.5 (highest emission scenario). The Maximum Likelihood Classification algorithm in ArcGIS was used to create the predicted future spatial patterns of strata and zones, using the modeled future climate conditions as prognosticated by each of the emission scenario combinations (n = 63) as input parameters (Robert J. Zomer; Marc J. Metzger; An

Countries with the Most Sustainable Energy Policies

World Energy Council – classifies nations based on their mix of tactics for tackling problems like energy safety and environmental sustainability.  1. Energy Security A nation’s ability to meet contemporary and future energy needs reliably, and jump back swiftly from system collapses with minimal interruption to satisfy. This dimension includes the effectiveness of the administration of internal and external energy sources, as well as the reliability and flexibility of energy infrastructure. 2. Energy Equity A country’s capacity to provide a universal way to reliable, affordable, and sufficient energy for residential and practical use. This dimension takes basic access to electricity and clean cooking fuels and technologies, access to prosperity-enabling levels of energy consumption, and affordability of power, gas, and fuel. 3. Environmental Sustainability The transformation of a country’s energy system towards decreasing and avoiding environmental harm and climate change im
