A protester demonstrating as part of the 'Exxon knew' movement in Washington, D.C. in 2015.

ExxonMobil's climate projections, made by in-house scientists between 1977 and 2003, were startlingly accurate and correctly predicted that fossil fuel burning would lead to global warming - while funding research and advertising to sow doubt about climate science. Read more»

While 70% of American adults describe climate change as an important concern, only 10% say they volunteered for an activity focused on addressing climate change or contacted an elected official about it in the previous year.

Global warming has increased the number of extreme weather events around the world by 400% since the 1980s, but there is a lack of of serious effort to combat the climate crisis - and one main reason is the public doesn’t believe in its own political power enough or use it. Read more»

Textbooks in the 70s and 80s focused primarily on describing the mechanics of the greenhouse effect, whereas books published in later decades contained significantly more information on harms such as sea level rise, risks to human health, species loss, extreme weather and food shortages. 

Evidence is mounting fast of the devastating consequences of climate change, but a study found that most college biology textbooks published in the 2010s contained less content on climate change than textbooks from the previous decade. Read more»

Climate model projections clearly show that warming beyond 1.5 C will dramatically increase the risk of extreme weather events.

The world could still, theoretically, meet its goal of keeping global warming under 1.5 degrees Celsius, a level many scientists consider a dangerous threshold - but realistically, that’s unlikely to happen, due to problems evident at COP27, the United Nations climate conference in Egypt.

As world leaders gather in Sharm el-Sheikh, Egypt, to discuss global climate policy at the 27th annual UN climate conference, Arizona leaders are working on the implementation of climate policy across the state.

Stark words greeted the leaders who have gathered in Egypt to discuss climate change at the United Nation’s annual conference - words that resonate with climate experts and some political leaders in Arizona, who are taking their own steps in the absence of a statewide policy. Read more»

Greenland will lose at least 3.3% of its ice, over 100 trillion metric tons. This loss is already committed – ice that must melt and calve icebergs to reestablish Greenland’s balance with prevailing climate.

Greenland’s ice sheet is set to retreat by at least 22,780 square miles, and - if all greenhouse gas emissions driving global warming ceased today - ice loss will raise global sea level by at least 10 inches. Read more»

Mexican Gray Wolf.

President Biden repealed a federal regulation that had giving landowners deference over habitat designations for endangered or threatened species by claiming they would face economic harm, and unveiled new initiatives aimed at combating climate change. Read more»

Heat waves are getting hotter and becoming more frequent, a great concern for everyone’s health - but especially for children, who are more susceptible to heat-related illness and the toll on their mental health affects their ability to learn. Read more»

Lake Powell, pictured near Wahweap, Arizona, is currently at a record low capacity of 24%.

The Southwest has been hit hard with dry conditions as shrinking snowpacks, parched topsoil and depleted reservoirs are symptoms of the West’s worst set of dry years since 800 A.D. - and there is a significant likelihood the megadrought continues. Read more»

Justin Anderson argues before the Massachusetts Supreme Judicial Court on March 9, 2022, in a bid to dismiss the commonwealth's lawsuit against Exxon Mobil under anti-SLAPP statute.

One of the world’s biggest oil and gas companies appeared to be running on fumes Wednesday as Exxon Mobil attempted to shield itself under a law that protects people or organizations from being sued for making statements in the public interest. Read more»

Tidal flooding is creeping farther into coastal towns like Miami Beach.

A new report led by scientists at the National Oceanic and Atmospheric Administration warns that sea levels are rising, and that will bring profound flood risks to large parts of the Gulf and Atlantic coasts over the next three decades. Read more»

Exxon, headquartered in Houston, argues that lawsuits filed by out-of-state politicians infringe on the sovereignty of Texas.

ExxonMobil is attempting to use an unusual Texas law to target and intimidate its critics, claiming that lawsuits against the company over its long history of downplaying and denying the climate crisis violate the U.S. Constitution’s guarantees of free speech. Read more»

The ‘bathtub ring’ around Lake Mead in June 2021 reflected record low water levels in the Colorado River reservoir, which fell below 35% capacity and triggered water use restrictions.

Alongside a global pandemic, 2021 was filled with climate disasters - some so intense they surprised the scientists who study them - and in the U.S., something in particular stood out: a sharp national precipitation divide, with one side of the country too wet, the other too dry. Read more»

La Selva Biological Station in northeast Costa Rica.

Tropical forests are among the best tools for fighting climate change and the loss of wild species - and research shows they recover surprisingly quickly: Tropical forests can regrow on abandoned lands and recover many of their old-growth features in as little as 10 to 20 years. Read more»

With 80% of the nation's population in urban areas, there are strong environmental, social, and economic cases to be made for the conservation of green spaces to guide growth and revitalize city centers and older suburbs.

The Build Back Better plan being debated in Congress would provide $2.5 billion to improve and maintain urban tree canopy - unshaded areas suffer from a heat island effect and trees help filter air pollution and absorb stormwater runoff - with focus on underserved communities. Read more»
