Sadly, many of the catastrophic effects of modern civilization’s fossil fuel binge are already baked into the cake due to the lag time between temperature and CO2. The effects we are seeing now are from our emissions decades ago. Mankind’s radical alteration of the earth’s chemistry in the atmosphere, oceans, and soils is causing what has been dubbed the Sixth Mass Extinction. And we’re doing it at a rate never before experienced on the planet and in novel new ways like the plasticization of the oceans. Did you know that the table salt you eat most likely has microscopic bits of plastic in it? Coral reefs, the ‘rainforests of the sea’, are dying off globally and they provide many vital services to mankind. Insects, the base of the food chain, are declining at alarming rates. With their numbers cut in half in the last four decades, "biological annihilation" is what researchers have called the alarming decline in vertebrate wildlife this century. Just follow the science and environmental news for a few months and you’ll fall into a deep depression if you have any empathetic bone in your body. Certainly the human experiment has been a disaster for the planet’s biological diversity and it may well spell the end for us as well. Ernst Mayr’s argument is being proved correct —that intelligence is a lethal mutation.

You must be referring to this study by Peter Cox at the University of Exeter which downplays the possibility of "catastrophic consequences": "…So, is it time to uncork the champagne, heave a big sigh of relief, and tell the fossil fuel companies to “Drill, baby, drill?” Actually, no. A rise in global average temperatures of 2.8º C will still be a disaster for the earth and every living thing on it. The extinction of existing species will continue, ocean levels will still rise significantly, and drought will force many millions of people to become climate refugees. “We will still see significant warming and impacts this century if we don’t increase our ambition to reduce CO2 emissions,” says Piers Forster.

"The world is already well on the way to the 1.5º C plateau, which has been enough to cause the Arctic ice sheet to melt and weather patterns around the world to shift — drier in some locations, wetter in others. More frequent and more violent storms are occurring, along with intensified forest fires in some locations. Even if Cox is correct, adding another 1.3º C on top of the temperature rise that has already occurred will cause unimaginable changes to the earth’s ecosystems."

"The report is comforting. The worst case scenario the world has been fretting about for decades may not come to pass after all. But there is a latent danger associated with this study. The climate denial industry — and it is an industry — could easily seize upon these findings and use them to justify ignoring carbon emissions entirely. They could be fodder for the automakers who resist higher fuel economy and emissions standards, the fracking companies who insist that a few methane leaks never hurt anybody, and all the other business interests who depend on fossil fuels for their livelihood. Expect it to be used to argue against climate action of any sort." https://cleantechnica.com/2018/01/18/good-news-study-claims-global-warming-will-disastrous-not-catastrophic/
