No matter your perspective on global warming, data confirms immense growth of CO2 emissions during the period from 1753-2004, from 3 million to 4.2 billion metric tons of carbon.

  • China and the United States combined are responsible for almost 40 percent of today's global CO2 emissions.
  • On a per capita basis, US CO2 emissions stabilized at 5 metric tons per person in the early 1980s. In contrast, China's per capita CO2 emissions are relatively low at 1.4 metric tons. Such per capita discrepancies are standard between developed and developing countries and are central to the call globally to ensure climate-friendly economic growth and development.

COVID-19: Scientists Say Coronavirus is Connected to Climate Change

(8 February 2021) Scientists at Cambridge university published research last month linking climate change and the COVID-19 pandemic, but it may not be what you think. Early in the pandemic, speculation and initial research suggested a potential relationship between seasonal weather conditions and the spread of COVID-19. What the researchers at Cambridge have found is a link between shifts in global bat diversity, climate change, and the evolution or transmission of the two SARS coronaviruses, SARS-CoV-1 (the virus that caused severe acute respiratory syndrome (SARS) pandemic) and...

2020: The Second Hottest Year on Earth

(9 February 2021) 2020 was the second hottest year on Earth since the 1880s, according to the 2020 Global Climate Report from The National Centers for Environmental Information. For the northern hemisphere, the 2020 land and ocean surface temperature was the highest ever recorded in the 141-year reporting history at +1.28°C (+2.30°F) above average. This was 0.06°C (0.11°F) higher than the previous record set in 2016. The southern hemisphere was hot last year as well, reporting the fifth highest land and ocean surface temperature on record.

IPCC: Climate Change Is Irreversible Over Thousands of Years

(10 August 2021) "Climate change is irreversible." This was perhaps the most significant conclusion of the most recent report by the Intergovernmental Panel on Climate Change (IPCC). The report, a product of the combined efforts of 234 scientists from 66 countries, projects that in the coming decades climate changes will increase in all regions of the globe, with increasing heat waves, longer warm seasons, and shorter cold seasons. Sea level will continue to rise, and the likelihood of crossing the global temperature increase level of 1.5°C (relative to the preindustrial period,...

Carbon Majors' GHG Footprint Revealed

(10 June 2021) While 30% of the world's largest corporations have already made a commitment to reducing carbon emissions, there are other companies whose economic activity is inextricably linked to greenhouse gas (GHG) emissions and for whom reducing their carbon footprint is barely feasible — the so-called "carbon majors." In its 2020 Carbon Majors report, the Climate Accountability Institute estimates that between 1965 and 2018, 493 billion tons of greenhouse gases (in CO2 equivalent), or 35% of global GHG emissions from fossil fuels and cement production, were emitted from the...
