| President Trump expressed his support on Tuesday night for a global effort to plant one trillion trees, which itself was announced at a gathering of business and political leaders in Davos, Switzerland, in January. A trillion trees, it was said at that meeting of the World Economic Forum, would go a long way in addressing climate change. | President Trump expressed his support on Tuesday night for a global effort to plant one trillion trees, which itself was announced at a gathering of business and political leaders in Davos, Switzerland, in January.

| But while trees — and particularly forests full of trees — are vital for swallowing up and storing carbon, currently absorbing 30 percent of planet-warming carbon dioxide, they are also extremely vulnerable in the age of climate disruptions. | But while trees — and particularly forests full of trees — are vital for swallowing up and storing carbon, currently absorbing 30 percent of planet-warming carbon dioxide, they are also extremely vulnerable in the age of climate disruptions. |
| In a hotter, drier, more flammable climate, like here in the Mediterranean region, forests can die slowly from drought or they can go up in flames almost instantly, releasing all the carbon stored in their trunks and branches into the atmosphere. | In a hotter, drier, more flammable climate, like here in the Mediterranean region, forests can die slowly from drought or they can go up in flames almost instantly, releasing all the carbon stored in their trunks and branches into the atmosphere. |
| That raises an increasingly urgent question: How best to manage woodlands in a world that humans have so profoundly altered? “We need to decide what will be the climate-change forest for the future,” is how Kirsten Thonicke, a fire ecologist at the Potsdam Institute for Climate Impact Research, framed the challenge. | That raises an increasingly urgent question: How best to manage woodlands in a world that humans have so profoundly altered? “We need to decide what will be the climate-change forest for the future,” is how Kirsten Thonicke, a fire ecologist at the Potsdam Institute for Climate Impact Research, framed the challenge. |

| Today roughly 40 percent of the European Union’s landmass is covered by trees, making it one of the most forest-rich regions in the world. It’s also ripe for wildfire. | Today roughly 40 percent of the European Union’s landmass is covered by trees, making it one of the most forest-rich regions in the world.

| In 2019, intense heat and drought helped spread fires across roughly 1,300 square miles on the Continent, a swath of scorched land 15 percent bigger than the decade’s annual average, according to preliminary data issued in mid-January by the European Forest Fire Information System. | In 2019, intense heat and drought helped spread fires across roughly 1,300 square miles on the Continent, a swath of scorched land 15 percent bigger than the decade’s annual average, according to preliminary data issued in mid-January by the European Forest Fire Information System. |
| Marc Castellnou, a 47-year-old fire analyst with the Catalonian fire services, has seen that shift firsthand here in the hot, dry hills of Catalonia, in northeastern Spain, where his family has lived for generations in a medieval village overlooking the Ebro River. | Marc Castellnou, a 47-year-old fire analyst with the Catalonian fire services, has seen that shift firsthand here in the hot, dry hills of Catalonia, in northeastern Spain, where his family has lived for generations in a medieval village overlooking the Ebro River. |
| His mother’s family grew almonds up here. The terraces they once hacked into these hard rocks still remain, along with the brick oven of the old farmhouse and a row of juniper trees, which, by local custom, signaled to anyone walking up from the coast that they could barter their fish for bread there. | His mother’s family grew almonds up here.

| The almond orchard has long been abandoned. In its place, a scrubby forest of short oaks and white pines has come up. Where goats once grazed, there is now a carpet of dry grass. A perfect landscape for fire. | The almond orchard has long been abandoned. In its place, a scrubby forest of short oaks and white pines has come up.

| What happened with his ancestors’ farm has played out across Europe, profoundly altering the countryside over the past half century. As farmers walked away from the land in favor of less backbreaking, more profitable ventures, forests came back. | What happened with his ancestors’ farm has played out across Europe, profoundly altering the countryside over the past half century.

| Now Mr. Castellnou has been setting some of those forests ablaze, getting rid of the grasses and low-lying shrub so the flames can’t as easily race up to the crowns of the young, frail pines. The last thing he wants his two young children to inherit is a hillside strewn with dry, flammable brush. | Now Mr. Castellnou has been setting some of those forests ablaze, getting rid of the grasses and low-lying shrub so the flames can’t as easily race up to the crowns of the young, frail pines.

| In Europe last year, wildfires raged as far north as Sweden. Drought and beetle infestations killed swaths of forests in Germany, prompting a debate over what trees to plant in their place. Britain had more wildfires last year than ever before on record. Spain saw one of the sharpest increases in the number of individual fires. The European Union described forest fires as “a serious and increasing threat.” | In Europe last year, wildfires raged as far north as Sweden.

| The forests of Europe have been shaped and reshaped by human hands over centuries. Trees were cut for fuel and timber, then terraced so farmers like Mr. Castellnou’s forebears could plant whatever would fetch the most money. | The forests of Europe have been shaped and reshaped by human hands over centuries.

| His ancestors chose a steep hillside and planted almonds. The grandparents of his wife, Rut Domènech, 39, cultivated hazelnuts. Nearly everyone had olives to supply oil for the year. Some grew grapes to make wine. Every bit of hill was under cultivation. | His ancestors chose a steep hillside and planted almonds.

| By the second half of the 20th century, Catalonians began abandoning the steepest, hardest-to-farm hillsides in favor of the valleys, where machines and fertilizers made farming easier and more productive. | By the second half of the 20th century, Catalonians began abandoning the steepest, hardest-to-farm hillsides in favor of the valleys, where machines and fertilizers made farming easier and more productive. |
| Mr. Castellnou’s father gave up working on other people’s almond orchards altogether. He helped construct a new highway, then a new nuclear power plant in the next town, then went to work in a factory making wooden picture frames. | Mr. Castellnou’s father gave up working on other people’s almond orchards altogether.

| As Catalonians migrated to cities, the fingerprints of climate change also emerged. Heat records were broken, one after another. The grass turned dry. The white pines began to drop their needles. | As Catalonians migrated to cities, the fingerprints of climate change also emerged. Heat records were broken, one after another. The grass turned dry.

| Farmers in the Montsant wine region of Catalonia now harvest earlier in the season; the heat sweetens the grapes too early, leading to higher alcohol content, and some worry whether they’ll have to switch to dessert wines. | Farmers in the Montsant wine region of Catalonia now harvest earlier in the season; the heat sweetens the grapes too early, leading to higher alcohol content, and some worry whether they’ll have to switch to dessert wines. |
| On an exceptionally hot day last summer, on a poultry farm, a pile of manure caught fire, as mounds of animal waste have done before. But so fierce was the wind that the embers traveled across the hills, causing fires up to 13 miles away. | On an exceptionally hot day last summer, on a poultry farm, a pile of manure caught fire, as mounds of animal waste have done before.

| Fire, Mr. Castellnou pointed out more than once, is nature’s way of reshaping the landscape for the future. What will come up on these denuded hills will be less homogeneous, he said, and more resilient for a new climate. | Fire, Mr. Castellnou pointed out more than once, is nature’s way of reshaping the landscape for the future.

| He favors what he calls managed burns, getting rid of low brush in order to prevent the next fire from raging out of control. And sometimes, he favors letting fires burn. It’s part of the natural ecology of the forest, he said. The white pines, for instance, reproduce only during fires, when their seed pods explode in the heat. | He favors what he calls managed burns, getting rid of low brush in order to prevent the next fire from raging out of control.
