The climate crisis is not a distant threat; it's happening right now and affecting what matters most to us. Hurricanes intensified by a warming planet and drought-fueled wildfires are destroying our communities. Rising seas and flooding are swallowing our homes. And record-breaking heat waves are reshaping our way of life.

The good news is we know how to turn the tide and avoid the worst possible outcomes. However, understanding what needs to be done can be confusing due to a constant stream of climate updates, scientific findings, and critical decisions that are shaping our future.

That's why the ABC News Climate and Weather Unit is cutting through the noise by curating what you need to know to keep the people and places you care about safe. We are dedicated to providing clarity amid the chaos, giving you the facts and insights necessary to navigate the climate realities of today -- and tomorrow.

Soaking rain eases drought in parts of US but dryness still a problem for much of the country

Widespread drought conditions are still a significant concern across the country, with parts of the Northeast, northern Plains and Southwest currently experiencing some of the worst impacts, according to a U.S. Drought Monitor update released Wednesday.

Overall, more than 40% of the contiguous United States remains in a drought. This is an improvement, however, from the beginning of the month when more than half of the lower 48 faced drought conditions. Recent heavy rain along the West Coast and parts of the Midwest brought significant drought relief to portions of Washington, Oregon, Wisconsin and Illinois.

As a result, drought coverage decreased from 45.48% to 41.45% versus last week. While some regions experienced a notable improvement, the recent soaking in the Northeast was only enough to pause the fire danger and trend of intensifying drought conditions -- for now.

The current drought situation in the Northeast took months to evolve, and it will take several more rounds of significant rainfall over the span of weeks or even months to completely eliminate the widespread drought in the region.

After a few rounds of beneficial rain, the National Oceanic and Atmospheric Administration's Climate Prediction Center says a large part of the country will likely experience below-average precipitation in early December, particularly in the West, Plains and East Coast.

Much of the western Gulf Coast and northern Plains could see above-average rainfall during this period. Drought relief across the country will, at the very least, take a pause through the beginning of next month.

Colorado River at a tipping point over drought threat, new study finds

A major water supplier in the West is once again in the spotlight for its unpredictable future.

The Colorado River, the water source for 40 million people across the west, is in a worse state than previously believed, according to a recent study published in Earth's Future.

Drought and dry conditions, compounded by climate change, put the Colorado River in greater jeopardy, the study's authors said.

"It doesn’t take a lot of climate change to put the system into a very vulnerable future," said Dr. Patrick Reed, a civil and environmental engineer at Cornell University and co-author of the study.

Colorado's West Slope River Basins "are essential water sources for the Colorado River and play a vital role in supporting the state of Colorado's local economy and natural environment," according to the study. The West Slope River Basins contribute nearly 70% of the streamflow deliveries to Lake Powell, the nation's second-largest reservoir.

But drought has significantly depleted Lake Powell’s water supply, leading to the first-ever water shortage in the Upper Colorado River Basin in 2021 and more dependence on the West Slope Basin supply.

"The Colorado River is extremely stressed and overallocated," Reed said.

The Colorado River supplies water to seven states and Northern Mexico. Agreements about how the water is divided are up for renegotiation in 2026.

US fuel economy hits record high as CO2 emissions hit record low, EPA says

U.S. fuel economy reached a record high in 2023 at the same time that greenhouse emissions reached a record low, according to the U.S. Environmental Protection Agency's annual Automotive Trends Report released Monday.

The report also states that model year 2023 electric vehicles and plug-in hybrid vehicles have reduced carbon dioxide emissions by 11%.

"This report provides a critical data-driven affirmation that strong, technology-neutral standards can underpin environmental progress while saving drivers money at the pump," EPA Administrator Michael Regan said in a statement.

New vehicle CO2 emissions are now at a record low of 319 grams per mile, which reduces the impact on climate change. Battery and plug-in hybrid vehicles, combined with fuel cell vehicles, are expected to reach 14.8% of overall vehicle production in 2024, a trend that is expected to grow across the industry, according to the report.

Passenger cars and light trucks accounted for 17% of total U.S. greenhouse gas emissions in 2022, underscoring the need for further reductions across the industry, experts said.

In surprise turn, world leaders reach $300B climate cash deal at COP29

In a surprising turn of events, world leaders at the United Nations climate conference in Azerbaijan announced they have reached agreement on a new deal that calls for wealthy countries to contribute $300 billion annually to help developing nations deal with the effects of climate change.

After fears no deal would be reached as talks broke down, the announcement came around 3 a.m. local time and was met with a standing ovation and a wave of relief.

The deal in question was the "climate cash" agreement, under which developed nations will contribute an annual target of $300 billion to help climate-vulnerable, developing countries deal with the consequences of climate change.

President Joe Biden on Saturday praised the agreement, while touting his administration’s work on climate change, saying "nobody" can undo America’s "clean energy revolution," in an apparent swipe at President-elect Donald Trump.

"Today at COP29, thanks in part to the tireless efforts of a robust US delegation, the world reached agreement on another historic outcome," Biden said in a statement, going on to say the "ambitious" deal "will help mobilize the level of finance – from all sources – that developing countries need to accelerate the transition to clean, sustainable economies, while opening up new markets for American-made electric vehicles, batteries, and other products."

Biden, who is leaving office in less than two months, said states and cities will continue to tackle climate change -- notably not mentioning the federal government, while adding that no one can overturn progress on the issue, repeating something he said last week while visiting the Amazon.

In a statement, U.N. Secretary-General Antonio Guterres said he had "hoped for a more ambitious outcome" on both financing and climate change mitigation efforts from the conference.

"But this agreement provides a base on which to build," he said in the statement. "It must be honoured in full and on time. Commitments must quickly become cash. All countries must come together to ensure the top-end of this new goal is met."

Mukhtar Babayev, Azerbaijan's minister of ecology and natural resources who served as the COP29 president, said in a statement the $300 billion goal "represents the best possible deal we could reach."

The U.N. climate conference, known as COP29, was anticipated to be the "finance COP" -- the site of negotiations to determine how much fighting the climate crisis would cost and who would pay for it.

In 2015, under the Paris Agreement, participating countries agreed to set climate financing goals in 2024 that would account for the needs of developing countries.
