John Kerry, President Biden's special climate envoy, is expected to travel to China next week for meetings with officials aimed at boosting collaboration, the Washington Post reported Saturday.

Why it matters: China is the world's largest carbon dioxide emitter and the U.S. is second-largest.

After co-piloting President Obama's efforts to fight climate change as vice president, Joe Biden is having his second go, releasing a broad infrastructure proposal his administration hopes will lead to meaningful legislation and investment into stemming U.S. greenhouse emissions.

The big picture: Though there are no concrete programs yet — Congress will have to formulate those — many in venture capital are hopeful such programs will provide new opportunities for startups tackling climate change.

President Biden's first budget request to Congress contains large increases in climate-change-related spending, on the order of $14 billion above the prior year's levels, according to a White House summary.

Why it matters: It provides details on how the White House hopes to translate its vow to act aggressively on global warming, both at home and abroad, into specific funding levels and agency-by-agency plans.

Climate change will lead to a less secure, more crisis-prone world that will strain global institutions, according to a major national security assessment released Thursday.

Driving the news: The “Global Trends Report,” produced every four years by the National Intelligence Council, spotlights climate change among the main structural forces shaping the next two decades.

An analysis finds "increasing evidence" of a fraying connection between economic growth and higher carbon emissions — a needed first step toward steep CO2 cuts.

Driving the news: The Breakthrough Institute's Zeke Hausfather finds that since 2005, emissions have become "decoupled" from GDP growth in 32 nations with a population of at least 1 million people.

The new(ish) group Law Students for Climate Accountability just launched a pressure campaign against the heavyweight law firm Gibson Dunn over its work for oil industry clients.

Why it matters: It's just one of many examples of how climate activism has been tactically evolving in recent months and years. That includes taking aim at a wider suite of corporate targets, like PR agencies and big tech, and intensifying a years-long focus on the finance sector.

The White House is making the case that its climate moves to date create enough credibility to press other nations to bolster their commitments at an upcoming summit.

Where it stands: Congress has barely begun digesting President Biden's proposed $2.2 trillion infrastructure package that's stuffed with the biggest clean energy investments any president has put forward. But a top official hinted Tuesday that it would rely on all the climate policy moves it has set into motion when Biden convenes world leaders for a virtual White House climate summit on April 22-23.

Partner? Rival? When it comes to China and climate policy, the White House answer to both questions seems to be yes.

Driving the news: The last few days underscore the delicate role that China is playing in White House climate efforts.

The clean energy think tank RMI just launched a nonprofit journalism arm called Canary Media that's staffed by well-known names in energy and climate reporting.

The big picture: Canary will be "at the forefront of the clean energy transition" with a mission to cover global efforts to fight climate change, per RMI, formerly the Rocky Mountain Institute.

The Australian Academy of Science quietly released a report on March 31 that underlines the stakes of President Biden’s April 22 climate summit and the next U.N. climate confab in Glasgow.

The big picture: The report, produced by Australia’s equivalent to the Royal Society of London, heaps doubt upon the feasibility of the Paris Agreement's target of limiting global warming to “well below” 1.5 degrees Celsius (2.7 Fahrenheit) compared to preindustrial levels by 2100.
