Hi, I'm Josh Haner and I'm a staff photographer at the New York Times covering climate change.
For years we've sort of imagined this picture of a polar bear floating on a piece of ice.
Those have been the images associated with climate change.
My challenge is to find stories that show you how climate change is affecting our world right now.

This is the Opinions, a show that brings you a mix of voices from New York Times opinion.
You've heard the news.
Here's what to make of it.
My name is Nicola Guess.
I am a registered dietitian and today we're going to be talking about ultra processed food ready meals, chocolate, biscuits, sausages, fizzy drinks, chicken nuggets, burgers and hot dogs.
Well, we know they may be delicious, but new research finds eating them too often could be taking years off your life.
Scientists now say these foods should be regulated with tobacco style warnings and advertising bans.
It's been an issue that's been bubbling for a number of years and I think really has come to the fore, particularly in the US and this is the time of year when people are thinking, how am I going to get healthy for the new year?
Like what am I going to do?
Should I be eating this or that?
And I think ultra processed food has now become the dominant question in nutrition.
And that really concerns me because I feel like five years ago we would be thinking, is this food healthy or not?
That's not what's happening now.
Patients are now asking, is this an ultra processed food?
And I'm going to be making the case that I don't yet think it is a useful way of describing whether a food is healthy or not.
