A new coalition has formed aimed at helping ensure federal efforts to expand solar power don't leave the poor and communities of color behind.

Driving the news: The dozen-plus members of the Solar Access for All Coalition include Earthjustice, Coalition for Community Solar Access, GreenLatinos, Solar United Neighbors and the NAACP.

Global energy-related carbon emissions will surge this year as coal, oil and natural gas consumption return from the pandemic that caused an unprecedented emissions decline, the International Energy Agency estimated Tuesday.

Why it matters: The projected rise of nearly 5% would be the largest since the "carbon intensive" recovery from the financial crisis over a decade ago, IEA said, putting emissions just below their 2019 peak.

The Biden administration has removed Trump-appointed atmospheric scientist Betsy Weatherhead from her role overseeing a comprehensive report on how climate change is affecting the U.S., the Washington Post first reported Monday.

Why it matters: Weatherhead has not been fired — merely reassigned to the U.S. Geological Survey — the move represents an effort by the Biden administration to remove Trump-era appointees from scientific roles, per CNN.

The Treasury Department offered more information Monday on plans to expand its focus on global warming, and said John E. Morton, a climate finance expert who served in the Obama administration, will lead the efforts.

Why it matters: Announcement of the new "Climate Hub" and Morton's appointment signal how the Biden administration is stitching climate policy into the fabric of agencies across the government.

International Energy Agency modeling underscores the kind of sweeping energy transformations needed in the relatively near future to meet the Paris Agreement's temperature goals.

The big picture: The chart above via IEA's World Energy Outlook last October shows changes in demand for various fuel sources in three IEA scenarios.

Amazon Monday morning announced investments in several new utility-scale wind and solar projects and said it's now Europe's largest corporate renewable power buyer.

The big picture: Look for a burst of corporate clean energy and climate pledges this week as companies hope to show their bona fides alongside this week's White House global climate summit and Earth Day.

Cities and states continue to push forward on their climate goals, raising their level of ambition as the White House prepares to host a global climate summit this week.

Why it matters: Cities account for a significant share of emissions and worked to reduce them despite the Trump-era federal pullback. City leaders also must prepare for climate impacts such as the sea-level rise and more intense heat waves.

Get ready for lofty statements, urgent calls for carbon-cutting progress, new pledges — and known unknowns about how much concrete action will follow — at President Biden's global climate summit this week.

What we're watching: The White House will showcase a new 2030 U.S. emissions-cutting target and unveil plans for billions of dollars to help developing nations fight climate change, according to Bloomberg.

The odds of calamitous climate events, from collapsing polar ice sheets and the ensuing sharp rises in sea levels to deadly heat waves, increases dramatically if the world exceeds the Paris Climate Agreement's temperature targets.

Why it matters: In order to have a decent chance of meeting the agreement's most ambitious temperature target — holding warming to 1.5 °C above preindustrial levels — greenhouse gas emissions need to be sharply reduced before 2030.
