Take a moment to cherish your plants and appreciate the animals you see around you.(CNN) In 50 years, a third of them may no longer exist.Using data from surveys that studied 538 animals, insects and plants from 581 sites across the globe, researchers John J. Wiens and Cristian Román-Palacios from the University of Arizona found that approximately one in three plant, insect and animal species could face extinction by 2070. However, things could be even worse if emissions continue to rise as rapidly as they have in recent decades. In a worst-case scenario, that number could rise to over 55%.In 141 years of record-keeping, there has never been a warmer JanuaryOf the 538 species studied, 44% of them have already experienced an extinction in a particular local area. The researchers found that local extinction sites had larger and faster changes in the hottest yearly temperatures than those that did not.Read MoreWhile many species were able to tolerate a moderate increase in maximum temperatures, 50% of the species had local extinctions if maximum temperatures increased by more than 0.5 degrees Celsius. That number rose to 95% if temperatures increased by more than 2.9 degrees Celsius. The researchers found that the key to predicting whether a population will go extinct is the maximum annual temperature, as opposed to the average yearly temperature. This is notable because average temperatures are typically used as markers in measuring climate change.With January going in the record books as the warmest January in 141 years and statistical analysis done by NOAA scientists predicting 2020 to be one of the five warmest years on record, the researchers believe there will be more local extinctions across the globe. And with summer heat waves potentially becoming more dangerous in the coming decades, the potential for loss of life will likely only grow from here.However, that number could drop if we make a collective effort to address climate change, they say.If we stick with the Paris climate agreementThe Paris Agreement was signed in 2015 by ministers from 195 countries from around the globe.It committed these countries to keep global warming below 2 degrees Celsius above pre-industrial levels and below 1.5 degrees, if possible.11,000 scientists warn of 'untold suffering' caused by climate changeThe researchers found that achieving the Paris goals could be the difference between extinction and survival for many species."Based on our sample of 538 species, we projected a loss of 30% of the species under a more extreme warming scenario, but only about 16% if we stick to the Paris Agreement," Wiens told CNN."So, think in 1 in 6 species, not 1 in 3."The researchers believe that some species loss is inevitable at this point, no matter what we do to curb greenhouse gas emissions. However, it is still possible to protect biodiversity and prevent massive species loss."I think that we should focus on preserving forests and other habitats in tropical areas, and this is part of the Paris Agreement," Wiens said."Preserving forests protects biodiversity and can help reduce or even reverse global warming. It's a win-win."If we don't stick with the Paris climate agreementThe Paris Agreement is an international pact aimed at curbing global emissions of heat-trapping gases.Unfortunately, studies have shown that so far, many countries are failing to meet the emissions cuts they set to limit climate change.Countries are not doing enough to keep Earth's temperature from rising to near-catastrophic levels, a UN report saysMaking matters worse, President Trump formally notified the United Nations that the U.S. would be pulling out of the Paris climate agreement in November. While it will take a full year for the U.S. to withdraw, losing the world's second-largest contributor of greenhouse gas emissions makes it more difficult to reach the agreement's goals."Some researchers have estimated that two-thirds of all species of plants and animals could be lost due to tropical deforestation alone," Wiens said."If you combine that with climate change (which can impact species in protected forests and other reserves), then it really is terrible. Even from our data alone, there are extreme warming scenarios where 55% of the species would be lost from intact habitats. And note that deforestation also increases global warming. It is a double whammy against biodiversity."Species that are in tropical regions are two to four times likelier to face extinction than those in temperate regions."This is a big problem, because the majority of plant and animal species occur in the tropics," Román-Palacios said.Many species have migrated to cooler habitats to escape the warming temperatures, but the researchers found that most will not be able to disperse quickly enough to avoid extinction."In a way, it's a 'choose your own adventure,'" Wiens said."If we stick to the Paris Agreement to combat climate change, we may lose fewer than two out of every 10 plant and animal species on Earth by 2070. But if humans cause larger temperature increases, we could lose more than a third or even half of all animal and plant species, based on our results."CNN's Drew Kann, Brandon Miller, Hannah Levy and Rob Picheta contributed to this report.

'Course REAL science - and your own F'ing EYES - says biodiversity is INCREASED by a warmer climate. 'The diversity of plants and animals in Earth's arctic regions is moderate. Tropical latitudes in contrast are teeming with different species...' What happened to Philip Haney? Hogwash Brainwashing at it’s best.
1000 new species a year are discovered. Stop trying to scare people to click Good. GoresHoax is not going to make the sky fall. CillSarain Depletion of our natural environment would weaken our resilience as a species Too bad ! Our hope is that climate change will somehow doom cnn to extinction. And either give rise to a new species and/or allow a more hardy one to further populate: adaptation.

You can add me to that list of not existing in 50 years as well. In 50 years CNN “could” and “may” stop posting statements that contain such words as it basically means you guys have no facts to back up your claims. At current rates, more like 20 years! 🤔 In 50 yrs humans prob won’t exist.. Who knows what’s going to happen. Life is for living NOW.
News flash in 50 years I want exist CNN is FEAR Porn for MORONS. Think for yourself God is in control. A thousand new species are discovered yearly. Stop with your never ending agitprop. What a load of garbage. No research behind it, just pure click bait But emissions are falling. They are now down to 1994 levels.
Discovery Ramps Up 'BattleBots' With 50 Hours of Programming (Exclusive)The cable network says the robot-fighting series is coming back with an 'unprecedented' amount of time on its schedule. Hurray! Yeaaaaahhhhhhh!!!! HyperShockTV Oooohhh, baby! I’m pumped!!!
🤷♂️ How is that, we are “all going to be dead in 9 years” Jesus is coming back before then! 'No more flights, no more cars, no more trains, no more food, no more air, and just die. If we're not willing to lay down and die as a people, there is no way the human race can survive.' It seems that we need to do something different.
But profits first! Said by all Republicans I wish vegetables like asparagus, broccoli, Anderson Cooper & Don Lemon would disappear... If that was true...which it is not...answer me this... Why are people living longer? Bullshit No onder, stop GeoEngineering OMG, I'm shocked with the comments here... we are doomed!

GREEN NEW DEAL Why do we call unspent fuel, emissions? The Earth has literally not figuratively hooked a hose to a tailpipe and closed the garage door. We need to Respend fuel properly. Major priority. djtwin But now isn’t the time for us to be stubborn about it....let’s wait until we can hardly survive.
Yolo! You do know that plants thrive with more C02 right? Where did this info come from? Please post it with your climate claims This just hurts my heart. It feels like our world is falling apart. When they do you will see the DominoEffect! ClimateCrisis Lies and fear mongering. Addie97039280 China is killing all what moves!

This needs to be campaigned broadcasted and retweeted as much as possible Who cares? Humans only have 13...errrr....14 months left...according to your BS agenda... They are getting smarter. Claiming the end in 50 years assures they are correct for 50 years vs claiming the end in 10 years. Enough of the doom and gloom scare tactics.
I'm a raccoon and sh*t has got nothing on me. I hope the works still exists in 50 years The earths climate has been changing for billions of years. We have had ice ages, heat waves many times. during the dark ages we were having a mini ice age. Species die and are created all the time. No amount of taxes will stop the earth from changing.
Climate News Network is working overtime But I thought we had only 10 years left?...which is it? This is heart breaking. We are killing our planet.
Blockchain 50Bitcoin may have brought the world blockchain, but the billion-dollar companies on this year’s Blockchain 50 are bringing it into a wide range of industries. Cypherium is better.
Very nice isnt that what evolution is for? lol! Declare Bernie the winner you cowards Hopefully it's Mosquitos!! But I thought we only had 10 years left?... So which is it?.. But AOC told me we will all be dead in 12 years. This must be some kind of mistake. No if only CNN would go extinct Hope Liberal Media and CNN are on that list.
They will adapt. Life will find a way. Simply Marvellous! At To The Human Limits Of Perfection And Accuracy, In Assessment And Estimation. Thanks So Much To Share.

meh, there's only one species I care about, and even nukes can't kill it off. How much the journalist was paid for this propaganda. We know that it is so lucrative for journalist and scientific to pushed this hoax. This is your news to run with utmost priority. Nobody’s schemes/plans matter if we lose our ecosystem.
And ? At this has been happening for billions of years. Hmmm 🤔 I wonder what happen to the dinosaurs 🦕 How do you have 538 animals, insects and plants from 581 sitese That's for sure... 🎸 ........2070? Gee...... I can’t wait! 😘 Good one less thing for people to bitch about.
No. Because end of the world is for the weak Where do they come up with this stuff. Oh yeah, they are funded by special interest government groups. Hmmmmmmm 7/8. well maybe they'll all just magically be fine at some time similar to the polar bear as 2070 gets closer Because of many of your sponsors. More doomsday propaganda
We must save bug s We should start saying climate change effects guns, they might listen finally Hopefully mosquitoes, ticks, and fleas are one of them.
This Industrial era is not working for this planet.
