Here are few of the things that scientists think may happen as the temperature rises. Some of them are already happening:
Glaciers melting - Many glaciers are already melting and shrinking throughout the world. If the temperature increases they will continue to melt. This will cause animals that rely on glaciers such as polar bears and other species to become extinct.
Ocean levels will rise - As the glaciers melt, the ocean levels will rise. This could cause flooding in cities located near the coast.
Migration of animals - Animals will migrate to cooler spots as their old habitats get too warm. This could upset the food chain and put some species in danger of extinction.
Extreme weather - Some scientists think that warming will fuel more powerful hurricanes as well as more droughts and flooding in different areas of the world.
Change in ecosystems - cold weather biomes such as the tundra will shrink, while desserts will continue to expand.

Answer:
Explanation:
La fecundación es el proceso por el cual dos gametos (masculino y femenino) se fusionan durante la reproducción sexual para crear un cigoto con un genoma derivado de ambos progenitores. Los dos fines principales de la fecundación son la combinación de genes derivados de ambos progenitores y la generación de un cigoto.
En el caso de las plantas con semillas pros, hay que diferenciar el fenómeno de la fecundación propiamente dicho (unión íntima de dos células sexuales hasta confundirse sus núcleos respectivos y, en mayor o menor grado, sus citoplasmas),1 del proceso biológico que lo antecede: la polinización, en el que los granos de polen, desarrollados en las tecas que contiene cada antera de un estambre (hoja reproductora masculina), son transportados por el viento o los insectos a los estigmas, donde germinan emitiendo un tubo polínico que crece hacia el ovario. En este caso no se trata de gametos, sino de esporas, pues cada grano de polen contiene dos gametos o células reproductoras masculinas
