Official Global Warming Thread

I doubt it. Alot of scientists consider Global Warming at worse would increase our global temperature by 4-5 degrees instead of what they once thought would be higher. 4-5 degrees would no doubt cause more and stronger disasters, but nothing on the level of global destruction. But water and food shortages would be worse for the poorer countries. My only issue is, we need to make more of an overall global effort to reduce carbon emissions and create bigger green projects moving forwards. We're already moving away from coal and most of the big powers are reducing their carbon footprint. But instead of minor reductions, we need a revolution in Green energy. This means governments changing policies, incentivize energy companies to move away from fossil fuels in a large and facilite/fund green projects with local and state governments to get the ball rolling in multiple avenues. All is not lost, but we haven't made that full step in that direction yet as a species and we need to if we want to REVERSE the effects of something we've been feeding into since the industrial revolution. We have technology, we just need policy-makers and the industry to make pivots in cleaner production AND consumption.

Lake Powell officials face an impossible choice in the West’s megadrought: Water or electricity​

Page, ArizonaCNN —
Lake Powell, the country’s second-largest reservoir, is drying up.

The situation is critical: if water levels at the lake were to drop another 32 feet, all hydroelectricity production would be halted at the reservoir’s Glen Canyon Dam.

The West’s climate change-induced water crisis is now triggering a potential energy crisis for millions of people in the Southwest who rely on the dam as a power source. Over the past several years, the Glen Canyon Dam has lost about 16 percent of its capacity to generate power. The water levels at Lake Powell have dropped around 100 feet in the last three years.

THE WEST'S MEGADROUGHT​



Bob Martin, deputy power manager for the Glen Canyon Dam, pointed toward what’s called the “bathtub ring” on the canyon walls. The miles of white rock represent this region’s problem.

“That’s where the water has bleached out the rock – and that’s how high the water was at one point,” Martin told CNN.

As water levels decline, so does hydropower production. The dam harnesses the gravitational force of the Colorado River’s water to generate power for as many as 5.8 million homes and businesses in seven states, including Nevada and New Mexico.

Bryan Hill runs the public power utility in Page, Arizona, where the federal dam is located, and likens the situation to judgment day.

“We’re knocking on the door of judgment day – judgment day being when we don’t have any water to give anybody.”

Forty percent of Page’s power comes from the Glen Canyon Dam. Without it, they’ll be forced to make up that electricity with fossil fuels like natural gas, which emits planet-warming gases and will exacerbate the West’s water crisis.

Loss of power at the dam would also mean higher energy costs for customers as the price of fossil fuels skyrockets.

Southern Nevada Water Authority's original water intake valve in Lake Mead -- in service since 1971 --is now standing above the waterline and, as of earlier this month, is no longer in use since it can no longer draw water.

“If nothing changes, in other words, if we don’t start getting some moisture for Page, in particular, we are looking at an additional 25 to 30% in power costs,” Hill told CNN.

Arash Moalemi, the Navajo Tribal Utility Authority’s deputy general manager, told CNN a loss of power at the Glen Canyon Dam would be devastating for the Navajo community.

“We have 40% unemployment, and our per capita income is a little over 10 thousand dollars,” Moalemi said. “Higher energy prices could mean some people aren’t able to heat or cool their homes.”

The federal government – which technically owns the hydropower flowing through federally managed dams – sells the electricity to states for what is often far less than the commercial market price. In a worst-case scenario, the Interior Department projects the dam could stop producing power by January.

The agency is now weighing an emergency action that would buy the dam more time.

If the water level falls another 32 feet, Glen Canyon Dam will no longer produce electricity.

In a letter to seven Western states this month, the Interior Department recommended releasing less water from Lake Powell to downstream states this year. The proposal calls for holding back the equivalent of 42.6 billion gallons of water in Lake Powell, which will mean deeper cuts to the amount of water people can use in Arizona, California, Colorado, Nevada, New Mexico, Utah and Wyoming.

More than 110 billion gallons of water have already been held back so far this year.

This impossible choice comes as new images show that Lake Mead – Powell’s downstream neighbor and the country’s largest reservoir – has dropped to such historically low levels that one of the lake’s original 1971 water intake valves is now exposed above the water line.

Inside the Glen Canyon Dam, the current water level is still producing energy.

At the dam’s power plant there are eight generators. The force of water traveling through 15-foot diameter pipes hits and spins turbines which then generate power. If water levels at Lake Powell drop just another 32 feet, those generators will stop spinning.

The climate crisis is forcing both federal and state governments to make tough choices and take drastic measures just to keep both power and water flowing to Americans in the Southwest.

The Interior Department is expected to make a final decision on how to handle the dire situation at the dam by early May.

The two largest reservoirs in California are already at 'critically low levels' and the dry season is just starting​

How many years do we realistically have left on Earth? Global warming and side effects are probably irreversible at this point.
 
Last week, there was flash flooding in my area. Had the streets looking like rivers.
