Eastern China set for record-hot summers, study says

By 2024, more than half of summers in eastern China will be as hot as in 2013, when the region was hit by a record-busting heatwave and devastating drought, a study said Sunday.

Based on current trends, the big heat will happen even if rising greenhouse gas emissions are braked over the next decade, it said.

The summer of 2013 was the hottest on record in eastern China—a massive 1.1 degrees Celsius (two degrees Fahrenheit) above the long-term average.

On 31 days, the temperature reached or exceeded the heatwave benchmark of 35 degrees Celsius—more than double the usual June-August tally.

Nine provinces, with half a billion inhabitants, were affected. Direct economic losses, in China's most populated and economically developed region, have been put at 59 billion renminbi ($9.6 billion).

Reporting in the journal Nature Climate Change, scientists in Beijing, Canada and the United States said the probability of a 2013-like summer in eastern China had increased by a factor of 60 since the early 1950s.

Adding to the risk is the region's rapid urbanisation, they said.

They pointed to an effect called the , in which concrete buildings and tarmac roads store heat during the day but fail to shed it all at night, thus ratcheting up the daytime temperature bit by bit.

The team, led by Xuebin Zhang of Environment Canada in Toronto, extrapolated temperatures on the basis of the region's weather from 1955 to 2013 and on internationally-used simulations for global warming.

"By 2024, at least 50 percent of summers will be as hot as the 2013 summer," they wrote.

The estimate holds for the lowest , which yields a warming scenario called RCP4.5, and for the highest emissions, called RCP8.5.

"The increase in summer heat would inevitably lead to more widespread, long-lasting and severe heatwaves in the region," the paper warned.

"(...) Combined with the region's rising population and wealth, (it) would produce higher risks for human health, agricultural systems and energy production and distribution systems if sufficient adaptation measures are not in place."

So is this AGW or is it local weather. I've been told the USA is not the World when it's colder than normal, but China is the world because it is because its hotter than normal?

Can any idiot progressive democratic environmentalist make a simple statement, when is weather weather and when is weather AGW?

Does "freethinking" actually "think" life is a duality? Things are simply black or white?

Based on current global warming trends, the big heat will happen even if...
What "current global warming trends" are they talking about?

Frethinking as never had an original thought in his life. He is obviously and sadly one of the individuals that think Sean Hanity speaks for God and doesn't have the intellectual capacity for rational reasoning. He's all hate and nonthinking.

What was the temperature like for the rest of China in 2013? Hmm?

"In China the average January temperature became the coldest in 28 years. In northeast China the average temperature in January 2013 decreased to −15.3 °C (4.5 °F), the coldest in 43 years, while in northern China it dropped to a 42-year low of −7.4 °C (18.7 °F). About a thousand ships were stuck in ice in Laizhou Bay, while 10,500 square miles of ice reportedly covered the surface of the Bohai Sea. About 180,000 cattle deaths were reported in northern China by January 10. On May 2, 2013, a minimum temperature of 16.6 degrees Celsius was recorded at the Hong Kong Observatory, making it the coldest May temperature since 1917. It was also the third coldest minimum temperature in May since recorded."

I can't help but crack up with AGW believers say I can't think...... So while they are spewing word for word democratic national committee talking points (just like you would expect paid progressive government trolls to do), they ignore the fact that for almost two decades there hasn't been any temperature rise. When asked about this, they spew the DNC talking points that the heat is going into the deep oceans..... but now Scientists at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California, analyzed satellite and direct ocean temperature data from 2005 to 2013 and found the ocean abyss below 1.24 miles (1,995 meters) has not warmed measurably.

I would suggest to the AGW believers, quit believing everything the DNC and Profit Al Gore says and start looking at facts independently. The AGW lie is still a lie even if it is spewed for 20+ years.

Colder Winters and Hotter Summers are still indicative of Climate Change. We called it Global Warming back before we noticed that with warming comes less weather stability overall. I'm in the US and we have had colder winters, but the season is only a part of the weather. It can be winter and a warm front boosts the temps to 80 F, and the next day a cold front comes in and it drops to 19 F. Seasons matter less and weather patterns matter more, atleast that is what I have observed in my time here on planet earth.

Maybe this way it'll work - when some big-wigs start to see that climate change is just bad business.

First off is Vietvet is the sockpuppet of NOM or is Nom the sockpuppet of Vietvet?
Second, are they Paid Progressive Government Trolls?

NOM

Curiously enough more than one person thinks you are a tosser.

... and
Paid?: yes
Progressive?: Your political definitions are meaningless to me
Government?: Yep - got that one right, but your govt - no
Troll?:Read the TOU. You are the one dragging pointless politics into every discussion.

You had better get back to your banjo practice Conservative Unpaid Nongovt Troll

@Freethinging is neither free thinking nor thinking nor free. Everything the @freestinks says sounds like paid for OBstructiCON! In the case of Phys.org, he tries to be the obstructicon of any climate change issue, even though he knows he is wrong, ignorant and stupid about the issue. He's the Ted Nudgent of obstructionism. I think @freestinks is the paid for troll sent in here to inject his master's venom into phys.org freedom. In other words, a POS.

So let's get back to the story; what do we do to avoid this disaster? "Eastern China set for record-hot summers".

You mean he craps in his pants and walks around in it for a week? Ewwww.....
