Climate change to overtake land use as major threat to global biodiversity

Climate change will have a rapidly increasing effect on the structure of global ecological communities over the next few decades, with amphibians and reptiles being significantly more affected than birds and mammals, a new report by UCL finds.

The pace of change is set to outstrip loss to vertebrate communities caused by land use for agriculture and settlements, which is estimated to have already caused losses of over ten per cent of from ecological communities.

Previous studies have suggested that ecosystem function is substantially impaired where more than 20 per cent of species are lost; this is estimated to have occurred across over a quarter of the world's surface, rising to nearly two thirds when roads are taken into account.

The new study, published today in Proceedings of the Royal Society B, shows that the effects of change on are predicted to match or exceed land use in its effects on vertebrate community diversity by 2070.

The findings suggest that efforts to minimise on global biodiversity should now take both land use and climate change into account instead of just focusing on one over the other, as the combined effects are expected to have significant negative effects on the global ecosystem.

Study author, Dr. Tim Newbold (UCL Genetics, Evolution & Environment), said: "This is the first piece of research looking at the combined effects of future climate and land use change on local vertebrate biodiversity across the whole of the land surface, which is essential when considering how to minimise human impact on the local environment at a global scale.

"The results show how big a role climate change is set to play in decreasing levels of biodiversity in the next few decades and how certain animal groups and regions will be most affected."

Dr. Newbold's research has found that vertebrate communities are expected to lose between a tenth and over a quarter of their species locally as a result of climate change.

Furthermore, when combined with land use, vertebrate community diversity is predicted to have decreased substantially by 2070, with species potentially declining by between 20 and nearly 40 per cent.

The effect of climate change varies around the world. Tropical rainforests, which have seen lower rates of conversion to human use than other areas, are likely to experience large losses as a result of climate change. Temperate regions, which have been the most affected by land use, stand to see relatively small biodiversity changes from future climate change, while tropical grasslands and savannahs are expected to see strong losses as a result of both and land use.

We need AT LEAST 8 times more co2 than we currently have, if we want to feed everyone. Clearly co2 has no effect on warming at all, BUT we are dangerously close to the lowest levels of co2 possible to support life on earth.

The point being that as more trees and other vegetation are planted, the CO2 requirements become greater to accommodate their daily life cycles of CO2 in, Oxygen out.
It appears that the more forests that are cut down, the higher levels of CO2 remain in the atmosphere and the waters. Which is why there should be very little cutting of forests where alternatives for wood may be manufactured instead.
One of the worst causes of GHG is wildfires, very often caused by careless humans. Homeless people living out in the woods are also sometimes inconsiderate toward the environment and innocent wildlife. Many homeless people are mentally ill who should be kept in institutions to prevent such lack of concern for our ecological welfare.

But let me add my good friend @antiboracle, you climate change denial is pretty freaking lame too. First you don't know the freaking science, and rely too much on alt-right website for your news and references. You and I could have a good beer with a scientist moment... but you seem to be so un-cool with all of the insults and made up stuff. I hate to say it, but a typical trump fan.

My suggestion is that governmental agencies should prevent humans from entering into forests UNLESS they are trained prior to entering such places wrt the prevention of wildfires and knowing how to keep it under control in the event that a small fire has already started. The Boy Scouts have training manuals in this regard. So, in addition to paying a fee to camp in the woods, each individual should reveal whether or not he or she is aware of how to prevent wildfires. It has nothing to do with human or civil rights, just good common sense.

I don't know that 'fascism' applies to preventing wildfires and wild animal deaths in the forests for the sake of the rights of humans to commit ecological/environmental atrocities. Ever been to a burned-out forest? Just imagine your loved ones being caught in a burning forest with no way to get out. Firefighters trying to stop a forest fire have been killed when they were unable to exit. It has nothing to do with politics. Just saving lives.

So you've been listening to Senator Cummings in his big 'know-nothing' speech about illegal alien babies parted from their illegal alien mothers, while claiming that there are "concentration camps" in America...even though Obama did the same thing while he was president - separating illegal babies from their illegal mothers who should not have been in the country in the first place.

I would like to see all of you phony "bleeding hearts" fork over half of your wealth to pay for the upkeep of these children and their mothers AND fathers/brothers/uncles/MS-13 members and the coyotes who have taken their money. Maybe you and other UNAMERICAN Liberal/Socialists will be willing to pay for these people from Guatemala, Honduras, and anywhere else in Central America OUT OF YOUR OWN POCKET.
They are only here to suck off the American teat just like so many who have arrived before them from Mexico.
Under the Trump Admin, there is far less unemployment among Blacks and Hispanics - all LEGAL Americans.

No, that much CO2 increase will probably cause a world famine from the resulting severe whether events devastating crops.

Clearly the science says neither of those things are true.
You should study the science before commenting about such things.

S_E_G, I've been talking to my father's kinfolk about you altright fairytails. The consensus seems to be that we need to apologize to the American People. For our great-greats accepting the bribes to look the other way as your gramps and greats snuck into our country.

Go back to the old country cesspit you barely escaped being born in. If they'll take you back! My understanding is that the old country sheep sleep a lot easier without you lot there to sneak up and bugger them every night.

I am sure that you are totally unaware of the fact that the American People come from many countries (legally) and they all differ in race, skin color/hair texture, etc., background, religion, political views and levels of wealth, education and intelligence.
Science has found that the Amerindians never originated in the Americas, but their ancestors crossed over from Mongolia into Alaska and down the peninsula. So everyone has originated from somewhere else...even YOU.

LOL It is odd, and yet it seems normal for your type to show your affinity toward the buggering of sheep. I would never have thought of such an activity, but YOU seem to know all about such things. I can only surmise that you are indulging, and have indulged in such bestiality, else why would you choose to talk of it?

We don't really know that. There was a glut of CO2 in the atmosphere during the Ediacarian age, I believe, and there was enormous growth of trees and vegetation to absorb the extra CO2 which, in turn, made it possible for an enormous amount of Oxygen to be produced that helped to bring about the Cambrian explosion of new life forms. (Oxygen breathers). That was ~540 - 560 MYA where "severe weather events" were of far less importance since the trees and other sturdy vegetation could weather normal or severe weather patterns. Agriculture has always been a hit-or-miss endeavor where one region could have plenty and another region could have famine. But a world-wide famine is very unlikely.

When did he learn that pose? How has the GOP even given this guy one node of recognition (and not be ashamed). Sure if you trust a lying grifter I guess you can dismiss everything and if your gullible enough to believe the grifter, your not going to make very good decisions, are you?

You have got to be kidding. Hillary Clinton in 2016 was already proving that she was a sick woman as well as unfit for the job of POTUS. And while President Trump has made a few mistakes in his life, he has turned out to be an honest, hard working man who understands business and the true leadership of the USA. Trump doesn't tell lies the way Barack Obama did. Remember "if you like your plan, you can keep your plan", and "if you like your doctor, you can keep your doctor". And remember that Obama claimed that his Obamacare would not cost very much, even while people who didn't want it had to pay a penalty. If Hillary had won, it would have meant 4 or 8 more years of Obama and his agenda of the destruction of the U.S.
Hillary would have been President "in name only" and Obama would have told her what he wanted her to do as he would have been the power behind the presidency.
Perhaps you don't like Trump because he's White and male?

It is possible that you are not aware that the Democrat Party of which Clinton and Obama are connected with, is the traditional Party of Slavery. Many Blacks and Hispanics have finally realised this and have gone over to the Republican side. One of the reasons that Democrats are against building the Wall is that they want the US to be flooded with Hispanics who will work cheap as farm laborers, mainly. The other reason is to give them full citizenship so that their votes will keep the Democrats in power.
The Democrats were responsible for slavery in the old South, and they want to continue slavery since most Blacks will not work as farm laborers. And now, the Dems have a whole new demographic to enslave from Central American countries. Obama was the one made a law to separate Central American kids from their parents WHILE HE WAS PRESIDENT.
Trump has just signed an Executive Order to stop that from happening.

I assume you mean by "Many" that you can count them on your hand. I really hate racist people. It's bad enough that we have history that has left ill will among Americans groups but damn, there is nothing worst than a modern day racist Obama hater and Trump butt kisser! But with Trump that is not the only issue; its that he was elected with the help of Russian intelligence that managed to socially engineer Mrs Clinton's electoral loss of the election.

The Deep State part is there, and it is the GOP grifter party totally in control of it with their Russian intel support team assisting and advising on every step. The GOP has morphed from the anti-slavery party into a crockpot stew of alt-right brain washed troll, stooges and bozos.

and we have renounced that position, yet you all GOP grifters have not. Your a party of HIPPOCRATES! You say one thing, lie and then move on to the next cover up lie. Example; you site Obama care as a lie; but it was Mitch McConnell that vowed to make it a failure. But he will stand right in front of you face and lie about who ever dumps the most money in is coffer that day. That @surveil is where you differ, You are corrupt! You believe in corrupt thoughts, and believe in a corrupt philosophy!

With child separations the norm for the GOP, It's not only corrupt, it is CONTEMPTUOUS!
