Biden Does NOT need a BILL to close the border
He only needs a PEN. Thats all he needed to open it.
Thats all he needed to close it. Thats all Trump needed.
Maybe this is just Proof Trump is better than Biden.

Last week, the annual summer melt of sea ice shocked scientists by falling 18 percent below the previous record low. Summer ice this year is half what it was 30 years ago and is disrupting weather patterns in the Northern hemisphere.
 
The vast Greenland ice sheet also experienced a record melt this year, nearly doubling the previous record melt said Marco Tedesco, an associate professor at the City College of New York and world-renowned specialist on the Greenland ice sheet.
 
Every summer, the surface of Greenland melts but this year’s melt was off the charts. Parts of Greenland ice continued to melt for 40 to 50 days longer than normal, Tedesco told IPS.
 
This process is being driven by warmer air temperatures, a drop in snowfall and the fact that much of the ice is no longer white but covered with black soot particles, he said.
 
Those soot particles come from burning diesel and biomass thousands of kilometres away, in Europe, Asia and North America. Snow and ice reflect much of the sun’s heat energy but the combination of the black soot and meltwater ponds, more of that heat is absorbed by the ice, leading to increased melting.
 
Shale gas production results in 40 to 60 percent more global warming emissions than conventional gas, Robert Howarth of Cornell University in New York State previously told IPS. Howarth has done two recent studies estimating the amount of methane escaping and concluded that natural gas from fracking was worse overall in terms of climate heating than burning coal.
 
Methane has 105 times the warming potential of CO2 over a 20-year time frame, after which it rapidly loses its warming potential. If large amounts of methane are released through fracking – as seems likely with hundreds of thousands of new wells forecast in the next two decades – Howarth says global temperatures could rocket upward from 0.8C currently to 1.8C in 15 to 35 years.
 
“We’d better have a zero tolerance for methane emissions from fracking,” said Baum.
 
However, even if there were mandatory requirements – presently there are none – it is difficult to enforce when governments at state and federal are cutting budgets and staff, said Baum.
 
All it would take is a few regulations and a few tens of millions of dollars over the next two decades to bring dramatic reductions in emissions of short-lived planet-heating pollutants like methane, black carbon or soot and smog.

What polution are you refering to, wvit? 400 ppm of CO2?

 Pure CO2 is delivered in bulk by truck to the greenhouse. Special storage tanks rented from the supplier are required at every site (Plate 6). The compressed CO2 is in a liquid state and must be vaporised through vaporiser units (Plate 7). The distribution system for liquid CO2 in the greenhouse is simpler to design and install. Most growers use 18 mm black flexible polyvinyl chloride (PVC) tubing with holes punched at an appropriate spacing (Plate Cool. For a small operation the CO2 may be supplied in cylinders.

When growers still growing in soil incorporate or surface apply animal manure or other organic materials, such as straw, levels of CO2 in the greenhouse will be increased during the breakdown process. The amount of CO2 produced depends on the stability of the mulch and the activity of the microorganisms, which convert the organic material into CO2. Production of CO2 from rotting manure will only be significant for about one month following incorporation. In some cases organic growing media such as coconut coir will increase the CO2 level in the greenhouse to 1,200 ppm during the night.

Leaks in the greenhouse allow a continuous infiltration   of outside air, which contains only 340 ppm CO2. An average   value for infiltration in a glass house would be one air change per hour.   To compensate for this dilution, approximately 0.37 kg CO2/100   m2 must be added to maintain the desired level of 1,300 ppm   CO2.

So LESS sunlight reaching the surface has a "heating" effect???  So if you want to warm your skin when you go outside, the best thing to do is carry an umbrella?

Now you understand why Vit's absurdities don't garner any respect.

So you're saying that I believe it's hotter in the shade than it is out in the sun?  Why would you think I would think anything so stupid as that as you do?
