LOS CAMBIOS CLIMATICOS AFECTAN LA AGRICULTURA.
En un nuevo informe de gobierno los científicos norteamericanos resaltan que el calentamiento global ya está afectando los recursos acuáticos y terrestres. Para tu comodidad, intercalamos un vocabulario blingüe a lo largo del audiotexto.

CLIMATE CHANGE AFFECTS AGRICULTURE |
AUDIO |

|
This is the VOA Special English Agriculture Report. A government report says climate change is already affecting American agriculture. |
|
report: informe; says: señala, indica; affecting: afectando; |
|
|
|
The new report is from the Climate Change Science Program, which brings together the research efforts of thirteen federal agencies. President George Bush launched the program six years ago. Here are some of the findings by scientists: |
|
brings together: concentra, reúne; research efforts: esfuerzos de investigación; federal agencies: organismos oficiales; launched: lanzó; six years ago: hace seis años; findings: conclusiones, hallazgos; by scientists: de parte de los científicos; |
|
|
|
The growing season has increased by ten to fourteen days in northern parts of the United States over the last nineteen years. |
|
growing season: temporada de cultivo; increased: aumentado, incrementado; by ten to fourteen days: de diez a catorce días; northern: del norte; over the last: en los últimos; |
|
|
|
Much of the East and South now get more rain than a century ago. But the report says there is some evidence of increased drought conditions in the West and Southwest. Western states have less snow and ice on the mountains and earlier melting in the spring. |
|
much of: gran parte de; get more rain: reciben más precipitaciones; a century ago: hace un siglo; evidence: prueba, evidencia, certeza;drought: sequía; western states: los estados occidentales; less snow and ice: menos nieve e hielo; earlier melting: deshielos anticipados; spring: primavera; |
|
|
|
Grain and oilseed crops are likely to develop faster with increased carbon dioxide in the atmosphere. But higher temperatures will increase the risk of crop failures. |
|
grain and oilseed crops: las cosechas de cereales y oleaginosas; are likely to develop: tienden a desarrollarse; faster: más rápidamente; increased carbon dioxide: aumento del dióxido de carbono; in the atmosphere: en el aire, en la atmósfera; higher: más elevadas; risk of crop failures: riesgo de fracaso en las cosechas; |
|
|
|
Also, horticultural crops such as tomatoes, onions and fruit are more easily affected by climate change than grains and oilseed crops. |
|
horticultural crops: las cosechas hortícolas; such as: tales como; onions: cebollas; more easily affected: afectadas con mayor facilidad; |
|
|
|
Fewer animals will die during warmer winters, but greater numbers will die during hotter summers. And temperature extremes reduce animal production of meat or milk products. |
|
fewer animals: pocos animales; will die: morirán; warmer: más cálidos; greater numbers: mayor cantidad; hotter: más tórridos; temperature extremes: los extremos de temperatura; reduce: reducen; milk products: productos lácteos; |
|
|
|
Forests in the West, the Southwest and Alaska already have increases in fires, insect outbreak and dead trees. But young forests on good soil will be more productive because of increased carbon dioxide levels. |
|
forests: los bosques; increases in fires: aumento de incendios; insect outbreak: ataque o invasión de insectos; dead trees: árboles secos; on good soil: sobre buen terreno; increased: incrementado, aumentado; |
|
|
|
At the same time, invasive plants will also grow faster and are likely to move northward. Recent research also suggests that weeds might get harder to kill with glyphosate, the most widely used plant killer in the United States. |
|
invasive plants: plantas invasoras; will also grow faster: también crecerán más rápido; to move northward: desplazarse hacia el norte; weeds: las malezas; might get harder to kill: podrían ser más difíciles de eliminar; glyphosate: glifosato (poderoso herbicida); most widely used: más ampliamente utiizado; |
|
|
|
The Department of Agriculture was the lead agency for the new report. Thirty-eight scientists from universities, national laboratories, nongovernmental organizations and federal service wrote it. They considered more than one thousand scientific publications. |
|
lead agency: organismo principal; nongovernmental organizations: organizaciones no gubernamentales (ONGs); wrote it: lo redactaron; one thousand: un mil; |
|
|
|
The report was the strongest statement yet by the Bush administration that human activity is the main cause of climate change in the last fifty years. Carbon dioxide from the burning of oil, natural gas and coal is the main gas blamed for trapping heat in the atmosphere. |
|
yet: a la fecha; main cause: causa principal; burning: combustión; coal: carbón; blamed for trapping heat: acusado de atrapar o concentrar el calor; |
|
|
|
The report says warming is very likely to continue in the United States during the next twenty-five to fifty years. And it says this is so even if future greenhouse-gas emissions are reduced. |
|
is very likely to continue: es muy probable que continue; this is so even: esto se mantendrá aunque; greenhouse-gas emissions: emanaciones con efecto invernadero; are reduced: se reduzcan; |
