A new study says when the weather heats up, things in the bedroom tend to cool down.
The study published in the National Bureau of Economic Research looked at the affects temperature shocks had on birth rates in the United States between 1931 and 2010. It found a steep decline in birth rates 8 to 10 months after days where the temperature went above 80 degrees. Did we need research to tell us there's nothing sexy about sweating from just sitting still?
While researchers noticed a partial rebound in birth rates during the fall months, it wasn't a full rebound, which leads them to the conclusion that as temperatures rise due to climate change, we'll see a decrease in population growth. This means as the planet keeps getting hotter, people are going to be having less sex.

Climate change will lead to less sex, new study says

The Obama Administrationâs hotly debated plan to cut the amount of heat-trapping carbon dioxide coming out of the nation's power plants will save about 3,500 lives a year from also reducing other types of pollutions, a new independent study concludes.

Evening rush hour traffic comes to a standstill on a hazy and polluted day in Beijing on December 1, 2010. China has met its 2010 target to cut emissions of key pollutants and is on track to meet its energy efficiency goal, state media said, quoting the country's top climate change official as saying after China last week acknowledged it had become the world's biggest emitter of the greenhouse gases that are blamed for climate change and global warming, surpassing the United States, though not in terms of emissions per capita. China's efforts to improve energy efficiency allowed for savings of 490 million tonnes of coal and prevented carbon dioxide emissions totalling 1.13 billion tonnes in 2006-2009, state media reported.

NEWBURG, MD - MAY 29: Emissions spew out of a large stack at the coal fired Morgantown Generating Station, on May 29, 2014 in Newburg, Maryland. Next week President Obama is expected to announce new EPA plans to regulate carbon dioxide emissions from existing coal fired power plants. (Photo by Mark Wilson/Getty Images)

FILE - In this Monday, Nov. 24, 2014 file photo, smoke streams from the chimneys of the E.ON coal-fired power station in Gelsenkirchen, Germany, and with a capacity of around 2300 MW of power it is one of the most powerful coal-fired power stations in Europe. Germany announced on Wednesday, Dec. 3, 2014 a cash boost for measures to cut greenhouse gas emissions, in a bid to meet its ambitious climate target for 2020. Germany has pledged to reduce its carbon dioxide output by 40 percent by the end of the decade, compared to 1990s levels. Current estimates predict it will only achieve a 32-35 percent cut.

FILE - In this Jan. 19, 2012 file photo, smoke rises in this time exposure image from the stacks of the La Cygne Generating Station coal-fired power plant in La Cygne, Kan. Carbon dioxide pollution has increased steadily, by 60 percent, from 1992 to 2013. In 1992, the world spewed 24.9 billion tons of carbon dioxide, now it is 39.8 billion, according to scientists at the Global Carbon Project international consortium. (AP Photo/Charlie Riedel, File)

Six countries produce nearly 60 percent of global carbon dioxide emissions. China and the United States combine for more than two-fifths. The planetâs future will be shaped by what these top carbon polluters do about the heat-trapping gases blamed for global warming. (AP Photo/Andy Wong, File)
LONDON - MARCH 25: Marketing manager Nick Cliffe of the 'Closed Loop Recycling' plant walks people through the recycling process on March 25, 2010 in London, United Kingdom. The state of the art plant is the first in the UK to produce food grade recycled plastic from bottle waste. Over 35,00 tonnes of plastic bottles are recycled at the plant annually, representing almost 20% of the plastic bottles currently collected for recycling in the UK, and saving approximately 52,500 tonnes of carbon dioxide per year.

In this photo taken Feb. 9, 2015, President Barack Obama listens in the East Room of the White House in Washington. The president is setting a goal of raising $2 billion from the private sector for investments in clean energy. The White House says it's launching a Clean Energy Investment Initiative as part of the Obama administration's effort to address climate change.The Energy Department will solicit investments from philanthropists and investors concerned about climate change. The aim is to spur development of technologies and energy sources that are low in carbon dioxide pollution, such as solar panels, wind power, fuel cells and advanced batteries.

While the nearby San Juan Generating Station will factor into New Mexicoâs proposed goal to reduce carbon dioxide emissions by one-third, the Four Corners Power Plant - which is located within the Navajo Nation - wonât. The Navajo Nation is pursuing an ownership stake in a coal-fired power plant in New Mexico as many utilities are divesting from the energy source. (AP Photo/Susan Montoya Bryan, File)
