Watch "The Power of Big Oil Part Two: Doubt," a FRONTLINE documentary. This episode is part of a three-part series.

It investigates the fossil fuel industry's historical efforts to sow doubt and impede action on climate change.

Independent analyses by NASA and NOAA confirm that Earth's global surface temperatures in 2019 ranked as the second-warmest since 1880. Temperatures were 2°F (1.1°C) warmer than the late 19th century, second only to 2016.

This data continues the planet's long-term warming trend, with the five warmest years on instrumental record all occurring in the last five years. More information is available at NASA's press release.

NASA reported that Earth's average surface temperature in 2022 tied with 2015 as the fifth warmest on record, continuing the planet's long-term warming trend.

Global temperatures were 1.6 degrees Fahrenheit (0.89 degrees Celsius) above the 1951-1980 baseline average, according to scientists from NASA's Goddard Institute for Space Studies (GISS).

Despite scientific consensus on human-induced global warming, former US President Donald Trump has consistently denied its human origins. In 2012, he famously claimed climate change was "a hoax invented by the Chinese to make US manufacturing less competitive."

This political stance, compounded by the pandemic, has significantly hindered environmental progress. SustainabilityX magazine summarizes Trump's impact and offers a "what not to do" list to inspire action for the new year.

We Mean Business Coalition and B Lab announce a new partnership to help companies accelerate greenhouse gas emission cuts. Join their CEOs on a LinkedIn Live event to mark this collaboration.

This conversational event will explore businesses' central role in delivering climate solutions, achieving a just transition to net zero, and acting as a force for good.

Tune in on May 4 at 1pm UTC to hear from Maria Mendiluce (CEO, WMBC) and Eleanor Ellen (Lead Executive, B Lab) as they discuss true climate leadership for responsible businesses.

Boudreaux, President & CEO, discusses Oberon Fuels' mission to decarbonize the fuel and energy sectors. The company aims to slash the environmental impact of fuels, particularly in hard-to-abate areas like heavy-duty transportation and agriculture.

Oberon achieves this through renewable dimethyl ether (rDME). Their low or carbon-negative rDME fuel can reduce LPG's carbon intensity by up to 60% when blended, potentially cutting global CO2 by 750 million metric tons annually. rDME also offers a compelling approach for transporting hydrogen for its fast-growing applications.

Sir David King, former chief scientific adviser to the UK government (2013–2017), discussed the governance of Arctic climate-altering technologies with the Carnegie Climate Governance Initiative (C2G).

At the 2019 Arctic Circle Assembly on October 10th, Sir David participated in two C2G sessions. There, scientists, policy experts, and civil society representatives explored critical questions concerning the Arctic's future.
