The man who introduced us to climate change has issued a dire warning about sea levels in New York.

In 1988, James Hansen told Congress that climate change is real. Now, his new paper spells out why it's much worse than what we thought.

The man who introduced us to climate change has issued a dire warning about sea levels in New York.

If anyone knows climate change, it's James Hansen.

The former NASA scientist gained credit for forging wide awareness of the issue when, in 1988, he told Congress "the evidence is pretty strong" that human-caused global warming is — well — a thing.

Hansen, who now works at Columbia University's Earth Institute, has a history of being ahead of the curve when it comes to climate science. So you can imagine why a new paper he's set to publish this week alongside 16 other researchers is causing quite the stir.

Hansen's new research claims sea levels could rise about 7 feet higher than other estimates throughout the next 85 years.

As we know, higher temperatures caused by increased global greenhouse gas emissions is melting ice near the Earth's poles. That means higher sea levels.

In his new paper, which will be published in the peer-reviewed Atmospheric Physics and Chemistry journal, Hansen claims that — unless humans start emitting way fewer greenhouse gases, like, nowice at the poles will melt at exponentially faster rates than currently predicted.

The IPCC, the U.N.'s panel focused on climate change, predicts sea levels to rise about 3 feet by 2100. That figure's already alarming scientists. Hansen's new research, however, predicts it'll be more like 10 feet.

A sea level 10 feet higher would make coastal cities like New York, London, and Shanghai completely uninhabitable.

It's sort of difficult to overstate how big of a deal that is. Not only would this affect millions of people, several trillion dollars worth of infrastructure could be destroyed.

“Parts of [coastal cities] would still be sticking above the water," Hansen said. “But you couldn't live there."

The year 2100 ... some of us could still be alive!

The discrepancy between Hansen's figures and the U.N.'s largely comes down to melting freshwater ice as opposed to melting saltwater ice.

Hansen's research claims that when freshwater ice on land (and not saltwater icebergs) melts into the oceans near places like Greenland and Antarctica, the colder freshwater traps the warmer, saltier water below. This trapped, warmer water causes further melting below the surface — a process that only increases the amount of additional water being added to our oceans as more freshwater ice melts into the sea.

Scientists have claimed that limiting global climate change to 2 degrees Celsius (about 3.6 degrees Fahrenheit) could protect the Earth from devastatingly high sea levels. But the trapped warmer seawater is increasing the melting process quicker than expected, according to Hansen, so that 2 degrees Celsius figure won't cut it.

The IPCC doesn't consider this freshwater effect in its projections. Hansen says there's evidence it's already happening.

But before you panic! Don't worry. There are reasons to be hopeful we can prevent the worst that global warming has in store.

After all, combating climate change is no longer on the world's back burner (global warming pun unintended).

Ahead of the the United Nations' climate summit in New York City back in September 2014, more than 400,000 people took to the streets to show world leaders that curbing climate change needs to be a priority.

And government bodies are listening. The U.S. and China, for example, reached a historic agreement just months after the climate march that will cut each country's coal consumption way back in the years to come. So far, China is taking the commitment seriously.

This will result in significantly less greenhouse gas emitted by two of the largest nations contributing to global warming.

Hansen agrees: We still hold the fate of our planet in our hands when it comes to climate change.

He said we “could actually come in well under 2 degrees if we make the price of fossil fuels honest." That means taxing fossil fuel-burning businesses and governments, which will encourage eco-friendlier practices.

Even with his latest research painting a dire future ahead, if Hansen believes we can make a meaningful difference in the decades to come, we all should.

But we have to act big, and we have to act now.

The "Big 5" is an old term from the colonial era, denoting the five wild animals in Africa that were the most sought-after kills for trophy hunters. Killing those five—lion, leopard, rhinoceros, elephant, and Cape buffalo—meant ultimate success in the big-game hunting world.

Now there's a "New Big 5," but instead of a barbaric goal for trophy hunters, it's a beautiful goal for wildlife photographers.

The initiative was created by British wildlife photographer Graeme Green with the goal of raising awareness about threats to the world's animals including habitat loss, poaching, illegal animal trade, and climate change. In a global call for votes, 50,000 wildlife lovers shared which animals they most wanted to photograph or see in photos. And the winners are:

Each year, an estimated 1.8 million people in the United States are affected by cancer — most commonly cancers of the breast, lung, prostate, and blood cancers such as leukemia. While not everyone overcomes the disease, thanks to science, more people are surviving — and for longer — than ever before in history.

We asked three people whose lives have been impacted by cancer to share their stories – how their lives were changed by the disease, and how they're using that experience to change the future of cancer treatments with the hope that ultimately, in the fight against cancer, science will win. Here's what they had to say.

In September 2013, Celine Ryan woke up from a colonoscopy to some traumatic news. Her gastroenterologist showed her a picture of the cancerous mass they found during the procedure.

Ryan and her husband, Patrick, had scheduled a colonoscopy after discovering some unusual bleeding, so the suspicion she could have cancer was already there. Neither of them, however, were quite prepared for the results to be positive -- or for the treatment to begin so soon. Just two days after learning the news, Ryan had surgery to remove the tumor, part of her bladder, and 17 cancerous lymph nodes. Chemotherapy and radiation soon followed.

Ryan's treatment was rigorous – but in December 2014, she got the devastating news that the cancer, once confined to her colon, had spread to her lungs. Her prognosis, they said, was likely terminal.

But rather than give up hope, Ryan sought support from online research, fellow cancer patients and survivors, and her medical team. When she brought up immunotherapy to her oncologist, he quickly agreed it was the best course of action. Ryan's cancer, like a majority of colon and pancreatic cancers, had been caused by a defect on the gene KRAS, which can result in a very aggressive cancer that is virtually "undruggable." According to the medical literature, the relatively smooth protein structure of the KRAS gene meant that designing inhibitors to bind to surface grooves and treat the cancer has been historically difficult. Through her support systems, Ryan discovered an experimental immunotherapy trial at the National Institutes of Health (NIH) in Bethesda, MD., and called them immediately to see if she was eligible. After months of trying to determine whether she was a suitable candidate for the experimental treatment, Ryan was finally accepted.

The treatment, known as tumor-infiltrating lymphocyte therapy, or TIL, is a testament to how far modern science has evolved. With this therapy, doctors remove a tumor and harvest special immune cells that are found naturally in the tumor. Doctors then grow the cells in a lab over the next several weeks with a protein that promotes rapid TIL growth – and once the cells number into the billions, they are infused back into the patient's body to fight the cancer. On April 1, 2015, Ryan had her tumor removed at the NIH. Two months later, she went inpatient for four weeks to have the team "wash out" her immune system with chemotherapy and infuse the cells – all 148 billion of them – back into her body.

Six weeks after the infusion, Ryan and Patrick went back for a follow-up appointment – and the news they got was stunning: Not only had no new tumors developed, but the six existing tumors in her lungs had shrunk significantly. Less than a year after her cell infusion, in April 2016, the doctors told Ryan news that would have been impossible just a decade earlier: Thanks to the cell infusion, Ryan was now considered NED – no evaluable disease. Her body was cancer-free.

Ryan is still NED today and continuing annual follow-up appointments at the NIH, experiencing things she never dreamed she'd be able to live to see, such as her children's high school and college graduations. She's also donating her blood and cells to the NIH to help them research other potential cancer treatments. "It was an honor to do so," Ryan said of her experience. "I'm just thrilled, and I hope my experience can help a lot more people."

Patrice Lee got into scientific research in an unconventional way – through the late ocean explorer Jacques Cousteau.

Lee never met Cousteau but her dreams of working with him one day led her to pursue a career in science. Initially, Lee completed an undergraduate degree in marine biology; eventually, her interests changed and she decided to get a dual doctoral degree in physiology and toxicology at Duke University. She now works at Pfizer's R&D site in Boulder, CO (formerly Array BioPharma), leading a group of scientists who determine the safety and efficacy of new oncology drugs.

"Scientists focused on drug discovery and development in the pharmaceutical industry are deeply committed to inventing new therapies to meet unmet needs," Lee says, describing her field of work. "We're driven to achieve new medicines and vaccines as quickly as possible without sacrificing safety."

Among the drugs Lee has helped develop during her career, including cancer therapies, she says around a dozen are currently in development, while nine have received FDA approval — an incredible accomplishment as many scientists spend their careers without seeing their drug make it to market. Lee's team is particularly interested in therapies for brain metastases — something that Lee says is a largely unmet need in cancer research, and something her team is working on from a variety of angles. "Now that we've had rapid success with mRNA vaccine technology, we hope to explore what the future holds when applying this technology to cancers," Lee says.

But while evaluating potential cancer therapies is a professional passion of Lee's, it's also a mission that's deeply personal. "I'm also a breast cancer survivor," she says. "So I've been on the other side of things and have participated in a clinical trial."

However, seeing how melanoma therapies that she helped develop have affected other real-life cancer patients, she says, has been a highlight of her career. "We had one therapy that was approved for patients with BRAF-mutant metastatic melanoma," Lee recalls. "Our team in Boulder was graced by a visit from a patient that had benefited from these drugs that we developed. It was a very special moment for the entire team."

None of these therapies would be available, Lee says without rigorous science behind it: "Facts come from good science. Facts will drive the development of new drugs, and that's what will help patients."

Cynthia Kuk was just 10 years old when they had a conversation that would change their life forever.

"My mother, who worked as a translator for the government at the time, had been diagnosed with breast cancer, and after her chemotherapy treatments she would get really sick," Kuk, who uses they/them pronouns, recalls. "When I asked my dad why mom was puking so much, he said it was because of the medicine she was taking that would help her get better."

Kuk's response was immediate: "That's so stupid! Why would a medicine make you feel worse instead of better? When I'm older, I want to create medicine that won't make people sick like that."

Nine years later, Kuk traveled from their native Hong Kong to the United States to do exactly that. Kuk enrolled in a small, liberal arts college for their Bachelor's degree, and then four years later started a PhD program in cancer research. Although Kuk's mother was in remission from her cancer at the time, Kuk's goal was the same as it had been as a 10-year-old watching her suffer through chemotherapy: to design a better cancer treatment, and change the landscape of cancer research forever.

Since then, Kuk's mission has changed slightly.

"My mom's cancer relapsed in 2008, and she ended up passing away about five years after that," Kuk says. "After my mom died, I started having this sense of urgency. Cancer research is such that you work for twenty years, and at the end of it you might have a fancy medication that could help people, but I wanted to help people now." With their mother still at the forefront of their mind, Kuk decided to quit their PhD program and enter medical school.

Now, Kuk plans to pursue a career in emergency medicine – not only because they are drawn to the excitement of the emergency room, but because the ER is a place where the most marginalized people tend to seek care.

"I have a special interest in the LGBTQ+ population, as I identify as queer and nonbinary," says Kuk. "A lot of people in this community and other marginalized communities access care through the ER and also tend to avoid medical care since there is a history of mistreatment and judgement from healthcare workers. How you carry yourself as a doctor, your compassion, that can make a huge difference in someone's care."

In addition to making a difference in the lives of LGBTQ+ patients, Kuk wants to make a difference in the lives of patients with cancer as well, like their mother had.

"We've diagnosed patients in the Emergency Department with cancer before," Kuk says. "I can't make cancer good news but how you deliver bad news and the compassion you show could make a world of difference to that patient and their family."

During their training, Kuk advocates for patients by delivering compassionate and inclusive care, whether they happen to have cancer or not. In addition to emphasizing their patient's pronouns and chosen names, they ask for inclusive social and sexual histories as well as using gender neutral language. In doing this, they hope to make medicine as a whole more accessible for people who have been historically pushed aside.

"I'm just one person, and I can't force everyone to respect you, if you're marginalized," Kuk says. "But I do want to push for a culture where people appreciate others who are different from them."
