'Last Chance': Warming Could Be Limited to 1.5°C With Immediate Phaseout of Fossil Fuel Infrastructure, Researchers Say

It is still possible to limit global warming to 1.5 degrees Celsius above pre-industrial levels, a study published Tuesday in Nature Communications found, as long as we act immediately to phase out fossil fuels.

The study used a climate model to determine what would happen if, beginning at the end of 2018, all existing fossil fuel infrastructure—from industrial equipment to cars to planes to ships to power plants—was replaced with renewable alternatives at the end of its design lifetime. The researchers found there would be a 64 percent chance of limiting warming to 1.5 degrees, in line with the most ambitious goal of the Paris agreement.

World’s Oceans Warming 40% Faster Than Previously Thought

An analysis of four recent studies of ocean temperatures has corrected some of the discrepancies between climate models that projected higher levels of ocean warming and observational data that turned up lower temperatures, concluding that the higher numbers were right.

Major Investors Pressure Exxon to Set CO2 Reduction Targets

The world's largest oil company is being pressured by major shareholders to take action on climate change.

Institutional investors with an estimated $1.9 trillion under management, led by the New York State Common Retirement Fund (NYSCRF) and the Church Commissioners of England (CCE), filed a shareholder resolution calling on ExxonMobil to set targets for lowering its greenhouse gas emissions, covering emissions from both its operations and the use of its products.

Report: Current Climate Policies Will Warm the World by 3.3˚C

This past October, a widely disseminated United Nations report warned that far-reaching and significant climate impacts will already occur at 1.5˚C of warming by 2100.

But in a study released Tuesday, researchers determined that the current climate polices of governments around the world will push Earth towards 3.3˚C of warming. That's more than two times the aspirational 1.5˚C target adopted by nearly 200 nations under the 2015 Paris agreement.

2018 Emissions on Pace to Hit ‘Record High’

As representatives from around 200 countries approach the end of first week negotiations on implementing the Paris agreement, a major new report underscores the urgency of their work.

The Global Carbon Budget 2018 was published in the journal Earth System Science Data Wednesday with the help of more than 70 authors from 53 research institutions, and the news is not good. After a three year lull in the rise of greenhouse gas emissions, emissions in 2018 are projected to shoot up by more than 2 percent, "a new record high," the report highlights from The Global Carbon Project said.

Ocasio-Cortez's Green New Deal Proposal Now Backed by 15 House Democrats

Calls for a Green New Deal are gaining traction in the two short weeks after the young climate activists of the Sunrise Movement and Representative-elect Alexandria Ocasio-Cortez stormed Democratic House Leader Nancy Pelosi's Capitol Hill office.

Fifteen members of Congress have now backed Ocasio-Cortez's proposal to establish a "select committee" in the House of Representatives to develop a plan to—basically—reduce greenhouse gas emissions and to transition the U.S. to 100 percent renewable energy sources within 10 years of passing the Green New Deal legislation.

The Last Four Years Were Likely the Hottest on Record

2018 will likely be the fourth hottest year on record, according to the United Nations' authoritative voice for weather and climate. The three years that were warmer? 2016, 2015 and 2017.

Furthermore, the 20 warmest years on record have been in the past 22 years, the World Meteorological Organization (WMO) said Thursday in its 2018 State of the Climate report.

EPA Head Wheeler Hints Administration Could Meddle With Next Climate Assessment

The Trump administration might have tried to bury the most recent U.S. government climate change report by releasing it the Friday of a holiday weekend, but it did not interfere with the writing of the report itself, officials at the National Oceanic and Atmospheric Administration confirmed to the Huffington Post. But if former coal lobbyist and U.S. Environmental Protection Agency (EPA) Acting Administrator Andrew Wheeler gets his way, that could change when it comes time to write the next national climate assessment.
